8. Care and maintenance

8.1 Care of insert tools
Remove any dirt adhering to the surface of the insert
tools and protect them from corrosion by rubbing them
with an oily cloth from time to time.
8.2 Care of the tool
Before cleaning, remove the battery from the tool in
order to prevent inadvertent starting.
-CAUTION-
Keep the power tool, especially its grip surfaces, clean
and free from oil and grease. Do not use cleaning agents
which contain silicone.
The outer casing of the tool is made from impactresis-
tant plastic. Sections of the grip are made from a syn-
thetic rubber material. Never operate the 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 tool. Clean the outside of the
tool at regular intervals with a slightly damp cloth. Do not
use a spray, steam pressure cleaning equipment or run-
ning water for cleaning. This may negatively affect the
electrical safety of the tool.
8.3 Maintenance
Check all external parts of the tool for damage at reg-
ular intervals and check that all controls operate fault-
lessly. Do not operate the tool when parts are damaged
or when the controls do not operate faultlessly. If nec-
essary, have the tool repaired at a Hilti service center.
Electrical parts of the tool may be repaired only by
trained electrical specialists.
8.4 Care of the battery
Keep the electrical contacts free from dust, oil and
grease. If necessary, use a clean cloth to clean the con-
tact surfaces.
Do not continue to operate the tool until the battery is
completely discharged as this may damage the battery
cells. Recharge the battery as soon as a drop in per-
formance is noticed.

7.9.2 Removing the insert tool
1. Remove the battery from the tool.
2. Turn the chuck ring to the ( ) symbol.
3. Pull the insert tool out of the chuck.
4. Turn the chuck ring back to the ( ) symbol.
At monthly intervals or, at the latest, when battery capa -
city drops significantly, the battery should be condi-
tioned as follows:
– With the C 7/24 or TCU 7/36 charger: Charge for 24
hours in normal charging mode or for 12 hours in
conditioning mode.
– With the C 7/36-ACS charger: The charger detects
automatically whether initial charging or normal char -
ging is necessary.
If, after conditioning, battery capacity is still unsatis-
factory, we recommend returning the battery to Hilti
for diagnosis.
8.5 Checking the tool after care and maintenance
After carrying out care and maintenance work on the
tool, check that all protective and safety devices are fit-
ted and that they function faultlessly.
