- For stubborn dirt, lightly dampen the cloth with water—avoid excessive moisture.
- Avoid using abrasive cleaners or solvents that could damage the surface.
Step 3: Clear Vents and Airflow Openings
Use compressed air to blow out dust and debris from the vents and motor cooling openings. Hold the can upright and keep the nozzle at a safe distance to prevent damage. Do not shake or tilt the can excessively to avoid propellant leakage.
Step 4: Clean the Chuck and Bit Holder
Wipe the metal chuck with a dry cloth. If there’s debris stuck inside, use a small brush or compressed air to clear it. Do not use liquids, as moisture can cause rust or damage the internal components.
Step 5: Inspect and Maintain Moving Parts
Check for any dirt or buildup around the trigger and gear area. Use a dry brush or compressed air to remove debris. Occasionally, apply a small amount of silicone lubricant to the chuck and moving parts—avoid over-lubricating.
