What You'll Learn

Keep ventilation slots clear
Maintaining the ventilation slots of your Dewalt corded electric drill is essential to ensure optimal performance and prolong the life of the tool. Here are some detailed instructions on keeping the ventilation slots clear:
First, it is important to understand why keeping the ventilation slots clear is crucial. The ventilation slots, also known as vents, allow airflow to circulate within the drill, helping to regulate its temperature and prevent overheating. Over time, these slots can become clogged with dust, debris, wood chips, and other particles, leading to reduced airflow and potential damage to the internal machinery.
To keep the ventilation slots clear, regular cleaning is necessary. Start by unplugging the drill or removing the battery to ensure it is turned off. Then, use canned or compressed air to blow into the ventilation slots and remove any accumulated dust and debris. Avoid using a brush as it may push the dirt further into the slots. Canned air can be purchased from most auto parts stores.
In addition to using compressed air, you can also gently blow into the ventilation slots to dislodge any debris. Alternatively, you can use a mild cleaning method by adding a few drops of mild dish soap to a rag, rinsing it with warm water, and gently wiping the vents to remove any remaining dust or grease. Ensure you wring out excess liquid from the rag before wiping.
It is recommended to clean your Dewalt corded electric drill weekly to maintain optimal performance and prevent the ventilation slots from becoming clogged. Always allow the drill to air-dry completely before storing it in a clean and secure area, preferably in its original case to minimise exposure to dust and moisture.
By following these instructions and keeping the ventilation slots clear, you can help ensure your Dewalt corded electric drill remains in good working condition for an extended period.

Inspect outer casing for cracks
Dewalt power tools are widely used by contractors and homeowners alike. They are lightweight, durable, and come in both corded and cordless versions. To maintain your DeWalt corded electric drill, it is important to inspect the outer casing for cracks.
Firstly, it is important to keep the drill clean. A few minutes of mild cleaning once a week will keep your DeWalt drill running and looking like new. Unplug the drill or remove the battery. Force a stream of canned air through the vents of the drill repeatedly to remove all dust. Canned air is available at most auto parts stores.
Next, add two drops of mild dishwashing soap to a rag and run it under warm water. Rub the soap into a lather and wring out the excess liquid. Wipe all areas of the plastic casing with the soapy rag, paying close attention to any crevices or cracks. Ensure you immediately clean grease off the cover of the drill as grease and oil can permanently stain the plastic.
After cleaning, allow the drill to air dry before inspecting the outer casing for cracks. If cracks are present, you may need to replace the outer casing. This will involve removing the outer shell of the drill to access the internal components.
By regularly inspecting your DeWalt corded electric drill for cracks and keeping it clean and dry, you can ensure its longevity and maintain its performance.

Check insulation on the power cord
To maintain your DeWalt corded electric drill, it is important to check the insulation on the power cord regularly. This is because the wire insulation coating inside motors can deteriorate over time due to typical wear and tear, moisture, or contamination. Failure to do so can lead to motor failure and lost production.
To check the insulation on the power cord of your DeWalt drill, you will need to inspect the insulation for any tears or damage. Look for any cracks or signs of deterioration on the insulation. If you feel a slight tingling sensation when using the drill, it may indicate an insulation issue, especially if you are standing in a puddle of water.
To test the insulation resistance, you can use a megohmmeter, which is specifically designed to measure the quality of insulation in cables. A typical megohmmeter applies a higher voltage than a standard multimeter and measures resistance in megohms, making it more suitable for testing insulation.
- Disconnect both ends of the power cord from the drill.
- Connect the black test lead of the megohmmeter between the common terminal and the ground wire of the power cord.
- Connect the red test lead between the Volts/Ohm terminal and one of the power conductors.
- Select the appropriate voltage setting, typically 1000V, and press the test button for several seconds.
- Allow a moment for the resistance reading to stabilize.
- Repeat the test between the second power conductor and the ground, as well as between the two power conductors.
- Ensure that the resistance between any two conductors is higher than 1 megohm.
By regularly inspecting the insulation on your DeWalt drill's power cord and utilizing a megohmmeter for more comprehensive checks, you can help ensure the drill's longevity and maintain your own safety.

Clean the drill regularly
To maintain your DeWalt corded electric drill, it is important to clean it regularly. This will ensure that your drill stays in good condition and prolong its lifespan. Here are some detailed instructions on how to clean your DeWalt drill:
Firstly, before you begin cleaning, it is important to unplug the drill from the power source. This is a crucial safety precaution to prevent any accidents. Once the drill is unplugged, use a can of compressed air to blow out any dust, debris, or wood chips from the ventilation slots. Ensure you wear safety glasses when blowing out the vents to protect your eyes from any debris that may be blown out.
Next, you can use a mild cleaning agent to wipe down the drill. Add a few drops of mild dish soap to a damp cloth and gently wipe down all areas of the plastic casing. Ensure you wring out any excess liquid from the cloth before cleaning. Grease and oil can stain the plastic, so it is important to clean these substances off immediately. Avoid using harsh cleansers or scrubbers as they may damage the drill.
Finally, allow the drill to air dry completely before storing it in a clean and secure area. Regular cleaning will help maintain the drill in good condition. Aim to clean your DeWalt drill once a week to keep it in optimal condition.

Store in a secure area
To properly store your Dewalt corded electric drill, you should first ensure that the tool is switched off and unplugged from the power source. It is important to store your drill in a secure area to prevent theft or damage and to ensure it doesn't accidentally turn on. A locked toolbox or shed is ideal. You should also ensure that the drill is clean and dry before storing it.
To clean your drill, start by forcing a stream of canned air through the vents to remove any dust or debris. You can purchase canned air from most auto parts stores. Next, add two drops of mild dishwashing soap to a rag, run it under warm water, and wring out the excess liquid. Wipe all areas of the plastic casing with the soapy rag, taking care to remove any grease or oil, which can permanently stain the plastic. Do not use harsh cleansers or scrubbers on the drill.
It is important to keep the drill's vents clear and the casing free of grease and dirt to prolong the life of the tool. A few minutes of mild cleaning once a week will keep your drill in good condition. Always wear safety glasses when blowing out the vents with air.
Before storing your drill, ensure that it is completely dry to prevent rusting. You can use a dry cloth to wipe down the drill, or you may choose to allow it to air dry. Once your drill is clean and dry, you can store it in a secure area until its next use.
