Maintenance Tips
-
Clean the motor after each use – Wipe dust and slurry from the housing and ventilation openings with a dry or slightly moist cloth; do not use running water to avoid water entering the motor or gearbox.
-
Check power cord & plugs – Inspect the power cable, plug and switch before operation for cuts or wear; damaged electrical parts reduce performance and can be unsafe.
-
Tighten fasteners & movable parts – Ensure all external screws, handles and mounting points are secure before drilling to maintain stability.
-
Lubricate drill bit threads – Apply water‑resistant grease to the spindle/bit threads for easier installation and removal of diamond bits.
-
Inspect seals & water connection – Check shaft seals and water inlet fittings for leaks; replace seals promptly if water leakage appears to protect internal components.
-
Replace gear oil & brushes per schedule – Have an authorized service agent replace gear oil and inspect/replace carbon brushes as needed to protect the gearbox and motor.
-
Store dry & protected – Always disconnect power and store the drill motor in a dry, cool area to reduce corrosion and prolong service life.
