8. Tips and Tricks

Only moderate pressure is required for hammer
drilling and chiselling. Applying a high degree of
pressure does not increase performance.
When drilling deep holes, remove the drill bit
periodically from the hole to remove dust.
Drill tiles and other brittle materials without impact.
9. Servicing
Always keep the safety coupling (17) clean and
free from dust.
Always keep the spindle (6) clean and apply a light
coating of grease. (for information on special
grease, see Accessories section: order no.
6.31800)
Keyless chuck (1) cleaning:
After prolonged use, hold the chuck vertically, with
the opening facing down, and fully close it and open
it several times. The dust collected falls from the
opening. The application of cleaning spray to the
jaws and jaw openings at regular intervals is
recommended.
Ventilation slits:
Clean the ventilation slits on the machine
occasionally.
10. Troubleshooting
If the trigger (13) can not be depressed, check to
see that the direction of rotation selector switch (11)
is fully set to the R or L position.
Electronic signal indicator (10):
Rapid flashing - restart protection
When power is restored after a power failure, the
machine - which is still switched on - will not start for
safety reasons. To continue operation, switch the
tool off and then on again.
Slow flashing - carbon brushes worn
The carbon brushes are almost completely worn.
If the brushes are completely worn, the machine
switches off automatically. Have the brushes
replaced by an authorized service centre.
