8 Service / Maintenance
Before starting inspection and service works shut
off the compressed air supply and secure it
against unintended activation!
CAUTION
The drive medium must be clean (filter 5 µm,
class 3). Unfiltered compressed air leads to high
wear, blocked silencers or complete break-down of
the impactor. The maintenance intervals will be
shorter.

The screw connections must be checked after an hour of
operation (after first startup), then at regular intervals and if
necessary be tightened and secured with Loctite.
If the safety rope has been extremely loaded by the vacuum
fixing device dropping down, it should be replaced by a new
one.
Vacuum fixing devices may be cleaned from outside with
pressurized water. After cleaning run the unit for a short
moment.
The suction cups must be permanently checked for wear and
need to be replaced if necessary.
The vacuum nozzle may be clogged by contaminated
compressed air. In this case the nozzle must be disassembled
and cleaned.
On VAC 8, VAC 10, VAC 11 and VAC 12 the externally
vacuum nozzle is easy to disassemble and clean.
Disassembly and cleaning of vacuum nozzles on VAC 13,
VAC 15, VAC 20, VAC 30 and VAC 40 should only be per-
formed by kÉííÉêVibration.
Clean if necessary. The maintenance intervals depend mainly
on the purity of the drive medium and the ambient conditions.
Replace filter insert, empty the filter when required or clean the
filter insert (wash out).
