Step 2: Brush Off Loose Dust and Debris
Use a soft-bristled brush or a dry cloth to gently remove dust, dirt, and debris from the surface, vents, and around the chuck.
Step 3: Use Compressed Air for Internal Cleaning
Hold compressed air about 6-8 inches away from the vents and motor housing. Use short bursts to blow out dust from hard-to-reach areas, avoiding direct contact with internal components.
Step 4: Clean the Chuck and Gear Case
Wipe the metal chuck and gear case with a clean, slightly damp cloth. For stubborn grime, use a mild degreaser or isopropyl alcohol on a cloth, then dry thoroughly.
Step 5: Inspect and Lubricate if Needed
Check the chuck for smooth operation. If needed, apply a small amount of lubricant designed for power tools to the chuck and moving parts, then wipe away excess.
