9 Tips and Tricks
When working with the chisel hammer, only a
moderate amount of press-on pressure (approx.
20 kg) is required. High press-on pressure does
not increase work capacity and can possibly
shorten the service life of your tool.
In the case of deep bores, pull the drill bit out of the
bore from time to time in order to remove the stone
dust.
10 Maintenance
Motor cleaning: blow out the machine regularly
and thoroughly through the air slots with
compressed air.

Rapid flashing - CODE! System
The tool was locked with a CODE! Key. The elec-
tronic anti-theft device is active. The tool can be
unlocked again with a CODE! key.
Slow flashing - carbon brushes worn (only KHE 75)
The carbon brushes are almost completely worn. If
the brushes are completely worn, the machine
switches off automatically. Have the brushes
replaced by an authorised service centre.

The tool cut out automatically. Bring the tool to a
Metabo Service Centre.
Rotational speed fluctuations:
High-energy, high-frequency interference can
cause rotational speed fluctuations up to the
maximum idling speed. The fluctuations disappear
again as soon as the interference fades away.
