9 Tips and Tricks

Only moderate pressure is required for hammer
drilling and chiselling. Exerting a high force does
not increase performance.
When drilling deep holes, remove the drill bit
periodically from the hole to release the stone dust.
Drill tiles and other brittle materials without impact.

10 Maintenance

Keyless chuck cleaning:
After prolonged use hold the chuck vertically, with
the opening down, and fully open and close 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.
The vent slots of the machine should be cleaned
from time to time.

11 Trouble Shooting

If the trigger (14) can not be depressed, check to
see that the direction of rotation selector
switch (12) is fully set to the R or L position.
Electronic signal indicator (9) with
VTC electronics (KHE 28, KHE 26, KHE 26 SP,
BHE 26, KHE Partner Edition)
Rapid flashing - restart protection
When power is restored after a power supply
failure, for reasons of safety the still switched-on
machine will not start. To continue operation switch
the machine off, 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.
