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 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 regu-
lar 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.

7.9 Charging the battery
Use only the Hilti C7/24, C7/36-ACS, SFC 7/18H, SFC
7/18 or TCU 7/36 charger.
Incorrect use may lead to electric shocks, overheating
of the battery or leakage of a caustic liquid from the bat-
tery.
Read the operating instructions for the charger before
beginning charging.
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 contact sur-
faces.
Do not fully discharge the battery, 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 capac-
ity drops significantly, the battery should be conditioned
as follows:
– by charging with the SFC 7/8 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.
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.
