DeWalt Impact Driver How to & Troubleshooting Guide

An impact driver solves all the problems your drill can’t fix. And while it may make working on your home projects much easier. Unfortunately, it can also make your life a living hell when it starts acting up. So keep reading to learn how to use an impact driver. And how to troubleshoot and fix it when it starts malfunctioning.

Why did my DeWalt impact driver stop working?

Below are some reasons why your impact driver is not working;

The battery is dead

If the impact driver does nothing when the trigger is pulled, first check to see if you have a dead battery. Remove the battery from the bottom of the tool, then attach a known charged battery.

Poor contact between the battery and the battery terminals

If you are certain the battery has charged, check to see if the contacts on the bottom of the tool are dirty or corroded. If so, clean them with a brush and contact cleaner.

Work out or dirty Brushes

Over time, the brushes in the tool will become worn and dirty to the point that the tool will cease to function. In this case, the brush assembly will need to be replaced.

Faulty Switch assembly

If the battery and contacts are good and the brush assembly is clean and functioning, then the culprit may be the switch assembly. Replace the switch assembly.

Faulty Motor

If the battery contacts, brushes, and switch assembly are all working properly, you must replace the motor.

How to service a DeWalt impact driver

Blow dirt and dust out of the main housing with dry air as often as dirt is seen collecting in and around the air vents. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

Note: Wear approved eye protection and an approved dust mask when performing this procedure. Never use solvents or other harsh chemicals to clean the tool’s non-metallic parts. These chemicals may weaken the materials used in these parts.

Charger Cleaning Instructions

Dirt and grease may be removed from the exterior of the charger using a cloth or soft non-metallic brush. Do not use water or any cleaning solutions.

WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning.

Why does my DeWalt Impact driver keep stopping?

The Impact driver may stall if overloaded, causing a sudden twist. Always expect the stall. Grip the impact driver firmly to control the twisting action and avoid injury. If the impact driver stalls, it is usually overloaded or improperly used.

Release trigger immediately removes impact driver bit from work and determines the cause of stalling. Do not depress the trigger on and off in an attempt to start a stalled impact driver. This can damage the impact driver.

To minimize stalling or breaking through the material, reduce pressure on the impact driver and ease the bit through the last fractional part of the hole. Keep the motor running when pulling the bit out. Always make sure you are using the correct impact driver bit for the application. 

DeWalt Impact Driver Chuck Wobble causes and fixes

The most common reason an impact driver doesn’t spin straight is that the impact driver bit is not properly centered in the chuck. Be sure the impact driver bit is fully inserted into the center of the chuck and is not clamped off-center.

More detailed instructions on properly inserting the impact driver bit are provided below, as well as couple more reasons your impact driver won’t spin straight!

Ensure the Impact driver Bit Is Correctly Inserted

Even a slightly off-center impact driver bit can make an impact driver unusable, and it’s easy to clamp the impact driver bit incorrectly or accidently. So here is what that looks like:

To ensure your impact driver bit is properly centered in the chuck, twist the chuck until the available hole is too small to insert the bit. Then open the hole slowly until the hole is just large enough to slip in the bit. Place the bit all way into the hole. Tighten and lock the bit in place.

This method forces the impact driver bit to be perfectly centered since the hole is never large enough for the bit to move around and become incorrectly oriented.

Inspect Your Impact driver Bit

Impact driver bits bend when they reach high temperatures, which frequently happens during use. So if you’ve used the impact driver bit before, it’s worth making sure it’s not the problem since it will spin strangely if your impact driver bit is bent.

If you think a bent impact driver bit might be the issue, test the impact driver with a different impact driver bit. Also, try a few different sizes – larger impact driver bit sizes are less likely to bend.

To ensure the impact driver bit isn’t the problem, you can also test the impact driver with a brand new impact driver bit. If the impact driver still has issues, it’s probably not the impact driver bit.

Inspect the Chuck

The previous two sections should have eliminated the possibility of user error, so it’s time to look a little closer at the impact driver itself. First off, if your impact driver is brand new, consider returning it to the store. Sometimes there are issues during manufacturing that cause problems with the chuck, and a different impact driver may solve the problem entirely.

If you haven’t used the impact driver at all, it’s easier to just get a different one than mess around with the solutions below;

If you’ve had the impact driver awhile, try retightening the chuck. After a fair amount of use, the chuck can become loose, causing the impact driver bit to wobble during use.

To tighten the chuck, remove the battery pack and select the middle “off” position of the rotation direction selector.

Then open the chuck jaws as large as they will go, and insert a hex key into the chuck. Finally, tighten the chuck around the hex key.

Turning the key by hand will result in turning the chuck. To tighten the chuck, grab a mallet and hit the hex key firmly in the clockwise direction to twist it. This will tighten the chuck on the spindle.

Remove the hex key and test your impact driver.

If this doesn’t solve your problem, consider replacing the chuck. Now, if you’re working with a fairly budget-level impact driver ($100 and under), you might be better off just buying a new impact driver. But for professional-level tools, replacing the chuck instead of the entire impact driver is worth your money.

Once you’ve installed a new impact driver chuck, removing the current impact driver chuck is similar to the tightening process. First, insert a hex key into the chuck, tightening the chuck around the hex key.

This time, instead of hitting the hex key in the clockwise direction, you’ll hit it in the counter-clockwise direction to loosen the chuck. Once the chuck is loosened, you can twist it right off the spindle and replace it with your new chuck.

DeWalt Impact Driver losing power

Below are some reasons why your impact driver is losing power;

Worn Brushes

When you use a brushed impact driver, you can see there is a carbon brush that will touch the commutator. The brush is used to supply the current to the winding (wiring loop). Each rotation brush is in touch with the commutator. When the brush touches, it can be worn due to friction. There is spacing in the commutator. When the brush is moving on it, it can be scratching.

When the tool is used for a long time, its brush is worn, and the electric supply can be weak. When the electric supply is weak, it affects the motor rotation directly. So you had better change the brushes when they reach 1/4 of the original length. Also, sometimes worn particles can be attached to the inner parts, shortening the commutator panels.

Use the tool in low temperatures. It will help to minimize the wearing due to friction.

Low Battery Capacity

Its capacity can be decreased when a battery is used for a long period because the current battery results from a chemical process. When the same process happens for a long period, its efficiency can be decreased if we see the battery has fully charged but may not. On the other hand, when we use that kind of battery, it can discharge quickly.

If this is happening continuously, replace the battery. Before using the battery, make sure it is fully charged. Then, follow the steps on how a battery can last long with maximum efficiency.

Winding Burning

We can see a wire wrapped around the armature when considering the brushed motors. Normally when the windings are increased, their power and smoothness also increase. However, when the winding is damaged for any reason or burning, its power can be reduced from the total power.

Although a winding plane has burned, the motor can be worked. But it will not produce the maximum torque and power the motor had. Its efficiency can be reduced due to this. You can observe only the torque has reduced when you use it.

You have to use an experienced electrician to check the windings. Changing the brushes will not solve this.

Sometimes dust can scratch the winding, and due to electricity, it can be short and burn. So make sure to lubricate the tool as much as possible and not to use it in the dusting area.

Trigger Damage

The trigger is used as a power switch of the impact driver. When the trigger is pressed, it provides electricity, and the motor generates power. So mostly, RPM depends on the trigger pressing. If we press less, there is low RPM; if we press completely, high RPM can be seen. So now you can realize if there is a problem with the trigger, its RPM can be changed.

If the trigger inside is clogged with dust or damaged wire and the current leaks, its performance will not be seen. Test the trigger with proper RPM before you use it. When you see this while you are working, you can see power lost. Service and maintain the trigger correctly.

Worn out Bearings

This is mostly happening in brushless motors. The bearing is used to fix the rotor with housing. So bearing supports to complete the rotation of the rotor. If there is a problem in the bearing, it can directly affect the impact driver spinning mechanism.

So if you use a brushless motor, you should pay attention to this matter. That is the most difficult part of the brushless impact driver. Of course, you can replace the bearing if there is a problem. But identify that early to reduce the damages.

Magnet Crashing

This is a really rare situation. However, if the tool is dropped from the high, it can break the inner magnets. When the magnets are breaking, their magnetic field can be weird. If you use the brushless impact driver, this can be seen.

Because most magnets are included in the rotor, which is outside the stator, remove the part by part if the torque is reduced to find the problem.

Power Supply Problems

Electric impact drivers are of two types. Cordless and corded are them. Both are based on the power supply to the impact driver. Normally corded impact drivers are powered with a permanent power cord. If there is any damage to the power cord, its performance can be reduced. So you had better check the power cord for a better power supply without any problem.

If you use the cordless impact driver, its battery and tool can be overheated due to high torque usage. So, performance can be reduced due to this. So, do not use the impact driver in the high torque requirement area.

When you fix the battery, it can be loose fixing. So its power will not receive to the motor. Therefore, you can see there is low performance. Make sure the battery is fixed with the tool and there are no internal particles to clog the connections.

Signs that you have a faulty trigger switch on your DeWalt impact driver

A broken switch can also cause the impact driver to lose variable speeds or fail to switch between forward and reverse mode. It will also cause the impact driver not to turn on. Fortunately, it is extremely easy to replace it.

How to replace a broken trigger switch;

  • To get started, open the impact driver casing.
  • Unscrew the two screws holding the transmission to the case, then a series of screws holding the two case halves together.
  • Separate the two halves of the impact driver. If a sticker on the base holds the two halves together, you’ll need to cut through it with a box cutter.
  • Remove the wires connecting the switch to the brush holder.
  • You’ll need to remove the impact driver’s motor assembly to do that. Remove the motor by removing the two screws outside the impact driver case that hold the transmission in place.
  • Remove the two blocks holding the motor assembly in place. These blocks are attached to the case by four screws.
  • Pull the motor and transmission assembly away from the impact driver.
  • Now you can separate the brush holders from the wires going to the switch. Be sure to note which wire goes to which brush holder, as you’ll need to reassemble it the same way.
  • Next, remove the switch from the impact driver.
  • The wires of the switch can be tested with a multimeter. But, first, test the current on both switches.
  • The wires of the switch can be tested with a multimeter. First, test the current on both switches.
  • Test its electrical continuity with a multimeter.
  • Set your multimeter to the continuity setting. Checking for continuity is done in the ohm’s settings. An ohm is the unit of measurement of resistance in a circuit. In addition, many multimeters have an audible tone setting which can be used when checking for continuity.
  • Touch one of the test probes on the multimeter to one of the battery connections on the switch. Then touch the other test probe to the opposite connection and pull the switch trigger. Repeat this process on the other side.
  • You’ll need to replace the impact driver’s switch if your multimeter does not beep or indicate resistance on either side.
  • Replacement switches can be found at for roughly $50. Test the new switch with the multimeter before installing.
  • Place the new switch into the impact driver body where the old one was. Then, route the switch’s wires into the impact driver’s housing.
  • Replace the wire to the lower brush assembly and replace the assembly with the impact driver.
  • Reinstall the motor and transmission assembly into the impact driver, and replace the blocks around the armature bearings to secure them to the housing.
  • Replace the two screws on the case that hold the transmission in place.
  • Reconnect the wire to the second brush holder and reinstall it into the impact driver. Tuck any wires that come out of the casing as necessary.
  • Finally, reinstall the other half of the impact driver casing, screw it together, and install the last two transmission screws.
  • Your impact driver should now be fully operable.

Common DeWalt impact driver trigger problems and their fixes

The trigger is jammed

The trigger cannot be pushed in, and the lock is in the off position. Therefore, the impact driver must be opened to remove the obstruction if the trigger is jammed. The impact driver should be removed, and the jam can be undone.

You can use pressured air to remove any debris trapped around the trigger. This will help loosen it. You may need to replace the trigger if the issue is a broken spring.

The trigger is too loose

The trigger is fully compressed, but the motor does not run. The trigger may also not fully recoil upon releasing it. If the trigger is loose, the impact driver can be opened up and easily tightened.

The trigger is broken

A rattling can be heard when the impact driver is shaken. Pressing the trigger does nothing. To remedy this issue, replace the trigger switch.

The trigger is disconnected from the motor

If the impact driver does not switch rotational direction, it is likely slightly shifted within the drill. Opening the drill and readjusting the switch will likely fix this issue.

The forward/reverse switch is not fully engaged to one side

If the forward/reverse switch is not fully engaged to one side, it will lock the trigger. Try moving the forward/reverse switch to one side fully.

The battery is dead

Remove the battery and charge it.

The wires are loose

If it fully engages, it may be a wiring or electrical issue. Check for any shorts, strips, or disconnects along the wires. If damage is found along wires, you may need to replace them.

The internal lock is inoperative

Open the drill and inspect around the forward/reverse latch for any debris, i.e., sawdust. If no debris is found, look deeper into the lock setting and see if the lock is bent or damaged. If so, replace the internal lock.

DeWalt 20V impact driver not charging

Your battery is not charging because;

The battery to charging connection is incomplete.

If the battery is not fully connected to the charger, it will not charge. First, check to make sure that the battery is clipped in. If it is fully pressed in, the issue may be within the battery or charger.

The charging dock is broken

Before buying a replacement, make sure the issue is in the charging dock by connecting the impact driver to a working charger. If the dock is the problem, buy a replacement.

The battery is faulty

The battery pack may not retain a charge, so a new battery is required. The issue can be distinguished if the impact driver works while connected to using a cord.

How long does the DeWalt 20V impact driver battery last?

The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. DeWalt warrants their Lithium-ion batteries for 2–3 years. That’s a real good indicator of their minimum expectations for those packs. If you take care of your batteries, there’s no reason not to expect them to last at least that long or longer.

DeWalt impact driver not impacting

To troubleshoot your impact driver;

1. Check the Battery

Most of the time, the problem occurs on the cordless impact drivers from DeWalt, and you will need to ensure that you are sorting it out perfectly to get the perfection that you might have been seeking with the work at hand.

To ensure that, you must check the battery power and health. If the batteries are not in the right health, they might not be able to provide the right power and current to all the components, and you will have to ensure that you are replacing the battery.

Yet, another problem might be the low charge on the battery. So, if your battery health is fine, you will need to ensure that you get the battery fully charged, and that should be helping you out perfectly to sort out this problem, and you will not have to worry about it again either.

2. Check Fuses

Once you get that sorted out and the problem is still there, you will need to make it right by checking on the fuses. There are several fuses on the impact driver, and you should ensure that you are fixing it properly.

You need to inspect the fuse for the impact motor on the Impact driver. If the fuse is blown, you will have to replace it with a new one to ensure that you can get it sorted out correctly, and that will ensure the right experience for you that you might be looking for on the impact driver.

3. Get it Checked

Lastly, if nothing so far has worked out for you. There might be something wrong with the wiring, or some other component such as the impact motor might have gone bad. It is better to get the impact driver thoroughly diagnosed by a DeWalt authorized technician, and that should be helping you out just perfectly in getting it sorted.

You will not have to worry about a single thing afterward for sure. They will be able to check if some wire has broken, some connector might not be connected properly, or the motor might have gone bad. So, you should ensure that it is fixed up properly, sorting out the problem for you perfectly.

DeWalt impact driver not spinning

Below are some reasons why your impact driver is not spinning;

The forward/reverse switch is not fully engaged to one side

If the forward/reverse switch is not fully engaged to one side, it will lock the trigger. Try moving the forward/reverse switch above the trigger to one side.

The trigger assembly is disconnected or broken

Disassemble the impact driver and check the wires going to the trigger assembly. If the wires are properly secured, the trigger assembly must be replaced.

The control switch is not in the lock position

On the left side of the drill, there is a control switch at the top of the handle. When the button is in the lock position, the drill will not perform. You need to press the control switch on the right side of the drill for it to move in a forward clockwise motion or on the left side fort to move in a reverse counter-clockwise motion.

Faulty battery pack

If the drill is not performing, check the battery pack at the bottom of the handle to confirm the battery is inserted correctly and locks into place with the latch fully engaged. If your battery pack is not properly charged, the drill will not operate.

The battery is dead

Remove the battery by squeezing the red tabs on either side of the battery. Now place it on the charger.

Dewalt Impact driver will rotate in one direction but not the other

The forward/reverse switch is not fully engaged to one side

If the forward/reverse switch is not fully engaged to one side, it will lock the trigger. Try moving the forward/reverse switch to one side fully.

The wires are loose

If the trigger fully engages, it may be a wiring or electrical issue. Disassemble the impact driver and check for any shorts, strips, or disconnects along the wires. If damage is found along wires, you may need to replace them.

The forward/reverse switch is broken

If the forward/reverse switch is broken, debris could hinder the switch from fully engaging. Disassemble the impact driver to troubleshoot. If further inspection reveals no debris, you may have to replace the switch.

Dewalt Impact driver Battery won’t charge

The main reasons your battery is not charging include;

Dirty or corroded contacts

Check the contacts on both the battery and the bottom of the tool. If they are dirty or corroded, clean them with a brush and contact cleaner.

Faulty Battery

If you have charged the battery and the driver is not working, test the battery with a volt meter. Place the positive lead of your volt meter on the positive contact of your battery and the negative lead on the negative contact.

If you do not see approximately 20 volts on the display of the volt meter, then chances are your battery is not good. And you should replace the battery with a new one.

Faulty Charger

If you put a battery on the charger and it does not charge the battery, but a different charger will charge the battery, your charger may be faulty. Replace the charger.

DeWalt impact driver lights not working

Poor connection to switch assembly

Open the tool and check the wire connection from the motor assembly to the switch assembly. If the connection is loose or disconnected, reconnect it. If the wires are damaged, replace them wires.

The switch assembly is faulty

Disconnect the switch, remove it, and replace it with a new one.

DeWalt impact driver not holding a bit

If the impact driver is not holding the bit;

The bit is not properly secured in the chuck

Remove the bit and inspect the chuck for any possible damage. If no damage is found, reinstall the bit and properly secure it in the chuck.

The Chuck is damaged or broken

Remove the chuck from the impact driver and replace it with a new chuck.

How to Replace the Chuck on a DeWalt Impact Driver

  • Use a pick and a small screwdriver to pry up one end of the retaining ring. Then pry it away from the impact driver.
  • Remove the flat washer, spring, and chuck collar. There is a ball bearing in the driver’s anvil. You do not have to remove this bearing, but be careful not to lose it.
  • With the tension removed from the bearing, you can tap the driver on your workbench to remove a broken driver bit if that’s why you removed the chuck.
  • Slide the collar into place and add the spring and flat washer.
  • Use a screwdriver to snap one end of the retaining ring into place. Then use another screwdriver or your finger to finish seating the retaining ring.

How much power does a DeWalt impact driver draw?

The average cordless impact driver has a battery that needs 25 to 100 watts, whereas most corded impact drivers need 800 to 1,200 watts to operate. An 18v cordless impact driver with a 250-watt motor will draw about 14 amps. While a 20V impact driver can draw up to 30 amps.

DeWalt impact driver works intermittently

The Impact driver may stall if overloaded, causing a sudden twist. Always expect the stall. Grip the impact driver firmly to control the twisting action and avoid injury.

If the impact driver stalls, it is usually overloaded or improperly used. Release trigger immediately removes impact driver bit from work and determines the cause of stalling. Do not depress the trigger on and off in an attempt to start a stalled impact driver — this can damage the impact driver.

To minimize stalling or breaking through the material, reduce pressure on the impact driver and ease the bit through the last fractional part of the hole. Keep the motor running when pulling the bit out. Always make sure you are using the correct impact driver bit for the application. 

Signs that my DeWalt impact driver is old and needs replacement

Here are some signs it is time to replace your impact driver;

Weakened Power

Your tool starts, but the power level is so weak that you’d probably be better off with a manual screwdriver. Or handsaw. Or bicycle pump. When your power tools lose their oomph (and it’s not a low battery), the most likely cause is old, worn carbon brushes that need replacing.

The carbon brushes are the small carbon blocks that transfer the electrical current from your power source to the tool’s motor. Unfortunately, these wear out through use. If your tool is losing power and doesn’t have the speed or strength it should, it could indicate that it is time to replace it.

Extreme wear and tear

Similar to a tool that won’t start, check your carbon brushes for any heavy wear or signs of damage. If your brushes are clear, there may be damage to your tool’s commutator or the rest of the assembly. Again, Discoloration, build-up, and even melted insulation are signs that these parts are the root cause.

Burning Smell

Malfunctioning motors give off a recognizable burning smell when something is wrong. Everything is still spinning, but the tool is no longer working and stinks.

Diagnosing this smell could change depending on your impact driver’s age, type and design. It could also just be a case of the tool overheating. Motors generate a lot of heat when in use. If the tool runs too long or too hard, the tool can overheat and cause a burning smell.

For safety purposes, immediately turn off any power tool emitting a burning smell and let it sit for about 30 minutes before attempting to diagnose the problem. If troubleshooting and repair does not work, it is time to replace it.

High-Pitched Screeching Noise

Using power tools can be pretty loud. However, sometimes a power tool starts making a high-pitched screeching noise or screaming; that goes above and beyond the loud hum of your electric hammer impact driver.

If your impact driver makes this noise, ensure it is properly lubricated. Check the manufacturer’s specifications for maintaining your tool to find the best method to keep your tool lubed.

Another easy tip for a squealing tool is to check the gears. If your tool has a forward and reverse control (as most powerful impact drivers do), your gear switch may get stuck between the gears. Move the switch back and forth and try running the impact driver again.

It is time to replace it if it still makes the screeching noise after lubrication.

Sparks and Smoke

Turn off your impact driver if begins to emit smoke or sparks immediately. You should never continue using power tools that are smoking or sparking. Set your tool aside and allow it to cool down before diagnosing or fixing an issue. Once the driver is cooled, check to see if any dust or debris has gotten into the tool.

Why are sparks and smoke coming from the Impact driver?

Excessive build-up of dust inside the case

If there is excessive dust inside your impact driver, you will need to take the impact driver apart and blow it out with compressed air.

The electric motor is shorting out and needs to be replaced

After disassembling the impact driver, if you see burn marks on the motor, it’s time to replace it.

Since this Impact driver has an electric motor that uses carbon brushes, sparks may be noticed in low light conditions, but if an excessive amount of sparks or smoke is noticed, do not continue to use the impact driver. If it still smokes after cleaning, it is time to replace it.

How to take care of your DeWalt impact driver batteries

Here are our top ten tips for getting the most out of your Lithium-Ion batteries, helping to maximize performance and runtime:

  • Use only original DEWALT batteries for best performance and safe compatibility with DEWALT tools and chargers.
  • Store and charge batteries in a cool, dry location.
  • Avoid exposing batteries to liquids, oils, or extreme temperatures.
  • Clean batteries with a slightly damp cloth; do not use solvents.
  • If your battery no longer holds a charge, take them to a DEWALT Service Center near you for fast, free, and safe disposal.
  • Follow proper transportation guidelines. For instance, engage the red transport cap when shipping FLEXVOLT batteries.
  • Disengage battery from tool before placing into storage for extended periods.
  • Fully charge the battery before storing it for extended periods (longer than six months).
  • Do not use batteries with visible damage or cracks.
  • Visit a DEWALT Service Center for help with your battery. Do not attempt repair or service.
  • Recharge only with the charger specified by the manufacturer. A charger suitable for one type of battery pack may create a risk of fire when used with another battery pack.
  • Use power tools only with specifically designated battery packs. Using any other battery packs may create a risk of injury and fire.
  • When the battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws, or other small metal objects, that can connect one terminal to another. Shorting the battery terminals together may cause burns or a fire.
  • Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts the eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

Dewalt Impact Driver Use and Care

  • Do not force the power tool. Instead, use the correct power tool for your application. The correct power tool will do the job better and safer at the rate at which it was designed.
  • Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
  • Disconnect the plug from the power source and the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
  • Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
  • Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Poorly maintained power tools cause many accidents.
  • Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp edges are less likely to bind and are easier to control.
  • Use the power tool, accessories and tool bits, etc., following these instructions, considering the working conditions and the work to be performed. Using the power tool for operations different from those intended could result in a hazardous situation.
