engage the catch and, at the same time, lift the unit

Care and maintenance

Care
The housing, container and cover are made of impact-
resistant plastic. The protective sleeve of the cable and
the hoses are made of an elastomer material. The out-
er sheath of the hose set consists of a hard-wearing
woven synthetic material.
Clean the parts of the unit regularly with a
damp cloth. Do not use spray equipment, a
steam cleaning system or running water for cleaning.
This may negatively affect the electrical safety of the unit.
Always keep the grip sections of the unit free of oil and
grease. Do not use cleaning agents which contain sili-
cone. Do not allow foreign objects to enter the interior
of the unit.
Regenerate the main filter and clean the container at
regular intervals, particularly before each long pause
between periods of use (e.g. at the end of the work-
ing day). Check the entire diamond drilling system for
leakage before each period of operation. Check and
clean the seals at regular intervals. Never leave drilling
slurry or water in the container for long periods.
Maintenance
Check all functional components and operating
controls of the unit for damage and correct oper-
ation at regular intervals. Do not operate the unit if parts
of it are damaged or when the operating controls do not
operate faultlessly. The unit should be repaired at a Hilti
service centre if necessary.

– Switching off after use.
