Care And Maintenance - Hilti SF180-A Bedienungsanleitung

7.9 Charging the battery
The battery cannot be charged through the belt adaptor.
Use only the Hilti C 7/24, C 7/36-ACS, SFC7/18H, SFC7/18
or TCU7/36 charger.
Incorrect use may lead to electric shocks, overheating
of the battery or leakage of a caustic liquid from the
battery.
Read the operating instructions for the charger before
beginning charging.
7.10 Changing the bit
-CAUTION-
The insert tool may become hot during use. There is a
risk of burning the hands. Wear protective gloves when
changing insert tools.

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.
The outer casing of the tool is manufactured from impact-
resistant plastic. The grip comprises a synthetic rubber
section.
The ventilation slots must be unobstructed and kept clean
at all times. Use a dry brush to clean the ventilation slots
carefully. Do not permit foreign objects to enter the inte-
rior of the tool. Use a slightly damp cloth to clean the out-
side of the tool at regular intervals. Do not use a spray,
steam-cleaning system or running water for cleaning.
This may negatively affect the electrical safety of the tool.
Always keep the grip sections of the tool free from oil
and grease. Do not use cleaning agents or polishes, etc.
containing silicone.
8.3 Maintenance
Check all external parts of the tool for damage at regular
intervals and check that all controls operate faultlessly.
Do not operate the tool when parts are damaged or when

the controls do not operate faultlessly. If necessary, 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 contact sur-
faces.
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 perfor-
mance 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 C 7/24, C 7/36-ACS, SFC 7/18 or
TCU 7/36 charger for 12 hours in conditioning mode.
If, after conditioning, battery capacity is still unsatisfac-
tory, we recommend returning the battery to Hilti for diag-
nosis.
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 fitted and
that they function faultlessly.
