Cleaning the Exterior
- Use a dry soft brush or microfiber cloth to gently remove dust and dirt from the surface.
- For stubborn grime, dampen the cloth with a mixture of mild detergent and water. Wring out excess liquid to avoid moisture entering openings.
- Wipe down the entire exterior, including vents and switches, ensuring no moisture gets into internal components.
Cleaning the Battery Contacts
- Use a dry cloth or a soft brush to clean the battery contacts and terminals.
- If corrosion or dirt is present, lightly dampen a cloth with isopropyl alcohol and gently wipe the contacts.
- Allow contacts to dry completely before reattaching batteries.
Cleaning the Chuck and Bits
- Remove drill bits from the chuck.
- Use compressed air to blow out dust and debris from the chuck.
