blown out from the motor at regular intervals (approx.
every four weeks), if possible using compressed air.
Conductive dust may collect inside the tool when it is
used under extreme conditions for working on metals.
This may reduce the effectiveness of the tool's electri-
cal insulation. In such cases, the use of a stationary dust
extraction system and a ground fault interrupter switch
(FI) are recommended. Dust should also be blown out
from the ventilation slots at frequent intervals.
Repairs / Carbon brushes
– The tool has been manufactured carefully and sub-
jected to stringent tests and inspections. Neverthe-
less, should it become necessary, the tool should be
repaired at a Hilti service centre.
– Repairs may be carried out only by trained electrical
specialists.
– The carbon brushes are of the automatic cut-out type.
The tool will be switched off automatically when it
becomes necessary to replace the carbon brushes.
Use only original Hilti carbon brushes.
– The tool requires no other maintenance.

Manufacturer's warranty – tools
Hilti warrants that the tool supplied is free of defects
in material and workmanship. This warranty is valid so
long as the tool is operated and handled correctly,
cleaned and serviced properly and in accordance with
the Hilti Operating Instructions, and the technical sys-
tem is maintained. This means that only original Hilti
consumables, components and spare parts may be
used in the tool.
This warranty provides the free-of-charge repair or
replacement of defective parts only over the entire lifes-
pan of the tool. Parts requiring repair or replacement
as a result of normal wear and tear are not covered by
this warranty.
Additional claims are excluded, unless stringent
national rules prohibit such exclusion. In particular,
Hilti is not obligated for direct, indirect, incidental
or consequential damages, losses or expenses in
connection with, or by reason of, the use of, or inabil-
ity to use the tool for any purpose. Implied warranties
of merchantability or fitness for a particular purpose
are specifically excluded.
For repair or replacement, send tool or related parts
immediately upon discovery of the defect to the address
of the local Hilti marketing organization provided.
This constitutes Hilti's entire obligation with regard to
warranty and supersedes all prior or contemporane-
ous comments and oral or written agreements con-
cerning warranties.
