Important:

You only need to apply minimal pressure for hammer
drilling. Do not apply too much pressure as this will
put unnecessary strain on the motor. Check the
hammer drill at regular intervals.
Re-sharpen or replace bits whenever blunt.
6. Maintenance
Always unplug the machine before starting any
maintenance work!
Keep your machine clean at all times.
Do not use aggressive agents to clean plastic
parts.
To prevent dust from collecting in the air vents,
clean them with compressed air (max. 3 bar)
each time you finish working with the machine.
Check the carbon brushes at regular intervals
(dirty or worn carbon brushes cause excessive
sparking and interference in speed).
