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 clean-
ing agents which contain silicone.
The outer casing of the tool is made from impactre-
sistant plastic. Sections of the grip are made from a
synthetic rubber material. Never operate the tool when
the ventilation slots are blocked. Clean the ventilation
slots carefully using a dry brush. Do not permit for-
eign 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 clean-
ing equipment or running 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 centre.
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 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 performance
is noticed.
At monthly intervals or, at the latest, when battery
capacity drops significantly, the battery should be con-
ditioned as follows:
– by charging with the SFC 7/18 H charger for 24 hours
in normal charging mode, or
– by charging with the C7/24, SFC 7/18 or TCU 7/36
charger for 12 hours in conditioning mode.
If, after conditioning, battery capacity is still unsatis-
factory, we recommend returning the battery to Hilti
for diagnosis.
