to cool down. Contact Hilti Service after the battery has been
allowed to cool.
The Li-ion battery features a charge status LED display. The
charge status is indicated by the LEDs on the battery during
charging (please refer to the operating instructions for the charger).
en
When the battery is not in use, pressing one of the battery release
buttons or inserting the battery into the power tool causes the
battery charge status to be displayed by the four LEDs for three
seconds.
7.11 Belt hook
CAUTION
Check that the belt hook is fitted securely before beginning
work.
The belt hook allows the power tool to be attached to a belt worn
by the operator. The belt hook can also be fitted to the other side
of the power tool for use by left-handed persons.
1. Pull the battery out of the tool.
2. Fit the mounting plate into the guides provided.
3. Secure the belt hook with the two screws.

8 Care and maintenance

CAUTION
Before beginning cleaning, remove the battery from the power
tool in order to prevent unintentional starting.
8.1 Care of insert tools
Clean off dirt and dust deposits adhering to the insert tools and
protect them from corrosion by wiping the insert tools from time
to time with an oil-soaked rag.
8.2 Care of the power tool
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 power tool is made from impact-resistant
plastic. Sections of the grip are made from a synthetic rubber
material.
Never operate the power 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 power
tool. Clean the outside of the power tool at regular intervals with a
slightly damp cloth. Do not use a spray, steam pressure cleaning
equipment or running water for cleaning. This may negatively
affect the electrical safety of the power tool.
8.3 Care of the Li-ion battery
Avoid entrance of moisture.
Charge the battery fully before using it for the first time.
In order to achieve maximum battery life, stop discharging the
battery as soon as a significant drop in performance is noticed.
NOTE
If use of the power tool continues, battery discharge is stopped
automatically (indicated by LED 1 blinking) before the battery cells
suffer damage.
Charge the battery with the Hilti charger approved for use with
Li-ion batteries.
NOTE
– A conditioning charge (as is required with NiCd or NiMH
batteries) is not necessary.
– Interruption of the charging procedure has no negative effect
on battery life.
– Charging can be started at any time with no negative effect
on battery life. There is no memory effect (as with NiCd or
NiMH batteries).
– For best results, batteries should be stored fully charged in a
cool dry place. Avoid charging the battery in places subject
to high ambient temperatures (e.g. at a window) as this has
an adverse effect on battery life and increases the rate of
self-discharge.
– If the battery no longer reaches full charge, it may have lost
capacity due to aging or overstressing. It is possible to
