Professional maintenance procedures to maximize tool performance and service life
Proper battery maintenance extends tool life and maintains performance
Avoid deep discharge; recharge at 20-30% capacity remaining
Store at 40-60% charge in cool, dry environment (15-25°C)
Avoid charging below 0°C or above 45°C ambient temperature
Use isopropyl alcohol to clean battery terminals monthly
Weekly inspection, monthly deep maintenance
Proper chuck maintenance ensures accurate drilling and secure bit retention
Remove debris from chuck jaws using brush and compressed air
Apply light machine oil to chuck threads and moving parts
Check for wear, cracks, or damage that affects gripping force
Inspect drill bits for wear, resharpen or replace as needed
After each use in dusty environments, weekly for regular use
