8.1 Care of the power tool
DANGER
When working on metal under extreme conditions, con-
ductive dust may accumulate inside the power tool. This
may negatively affect the power tool's protective in-
sulation. Under such conditions, the tool should be
plugged into a ground fault circuit interrupter (GFCI)
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 air vents are
blocked. Regularly clean the power tool's air vents care-
fully with a dry brush. Do not permit foreign objects to
enter the interior of the tool. The motor's fan will draw
dust into the casing and an excessive accumulation of
conductive dust (e.g. metal, carbon fiber) may cause
electrical hazards. 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 elec-
trical safety of the tool. Always keep the grip surfaces

of the tool free from oil and grease. Do not use cleaning
agents which contain silicone.
NOTE
Frequent work on conductive materials (e.g. metal, car-
bon fiber) may make shorter maintenance intervals nec-
essary. Take your individual work place risk assessment
into account.
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
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.
Possible cause
Interruption in the electric supply.
The supply cord or plug is defective.
The carbon brushes are worn.
The electronic restart interlock is acti-
vated after an interruption in the elec-
tric supply.
The extension cord's conductor cross
section is inadequate.
Press the on/off switch as far as it will go.
In this way, the hand is closed around the power
tool, which ensures optimum safety while working.
maintenance
Remedy
Plug in another electric appliance and
check whether it works.
Have the parts checked by a trained
electrical specialist and replaced if
necessary.
Have it checked by a trained electrical
specialist and replaced if necessary.
Switch the power tool off and on
again.
Use an extension cord with an ade-
quate conductor cross section.
