Care And Maintenance; Care Of The Battery - Hilti UH 240-A Manual De Instrucciones

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 capa-
city drops significantly, the battery should be conditioned
as follows:
– With the C 7/24 charger: Charge for 24 hours in nor-
mal 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 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.
