8 Care and maintenance
CAUTION
Disconnect the mains plug from the power outlet.
8.1 Care of the power tool
DANGER
Under extreme conditions, when used for working on
metal, conductive dust may accumulate inside the tool.
This may have an adverse effect on the tool’s protective
insulation.
Under such conditions, the tool should be
plugged into a ground fault circuit interrupter (RCD)
and use of a stationary dust removal system and
frequent cleaning of the tool’s cooling air slots is
recommended.
The outer casing of the power tool is made from impact-
resistant plastic. Sections of the grip are made from a
synthetic rubber material.
Never operate the power tool when the ventilation slots
are blocked. Clean the ventilation slots carefully using
a dry brush. Do not permit foreign objects to enter the
interior of the power tool. Clean the outside of the power
tool at regular intervals with a slightly damp cloth. Do
not use a spray, steam pressure cleaning equipment or
running water for cleaning. This may negatively affect the
electrical safety of the power tool. Always keep the grip
surfaces of the power tool free from oil and grease. Do
not use cleaning agents which contain silicone.
8.2 Maintenance
WARNING
Do not operate the power tool if parts are damaged,
if the electronic control unit is defective or when the
controls do not function faultlessly. Have the power
tool repaired by Hilti Service.
WARNING
Repairs to the electrical section of the power tool may
be carried out only by trained electrical specialists.
Check all external parts of the power tool for damage
at regular intervals and check that all controls operate
faultlessly.
8.3 Checking the power tool after care and
maintenance
After carrying out care and maintenance work on the
power tool, check that all protective and safety devices
are fitted and that they function faultlessly.
