Prepare the Drill
Ensure the drill is turned off and unplugged or the battery is removed. This prevents accidental activation during cleaning. Remove any bits or attachments to access all surfaces easily.
Clean the Exterior
- Use the microfiber cloth to wipe down the entire exterior of the drill, removing surface dust and dirt.
- Gently brush around vents, buttons, and crevices with the soft brush to dislodge debris.
- If needed, lightly dampen the cloth with isopropyl alcohol to remove stubborn grime, then dry immediately.
Clear Dust from Vents and Motor Housing
Use compressed air to blow dust out of vents, motor housing, and other hard-to-reach areas. Hold the can upright and use short bursts to avoid moisture buildup. Do not insert the nozzle directly into small openings—maintain a safe distance.
Inspect and Maintain Internal Components
If you’re comfortable, remove the battery and open the drill casing if possible (referring to manufacturer instructions). Use compressed air to clear internal dust. Do not use liquids inside the casing, as moisture can damage electrical parts.
