7.8 Reading the charge status LED display on
Li ion batteries 6 7
NOTE
The charge status cannot be indicated while the power
tool is in operation. LED 1 blinks when the battery is
fully discharged or when it is too hot (temperature
above 80°C). The battery must then be inserted in the
charger.

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.

CAUTION
If the battery gets too hot to touch, this may indicate
that it is faulty. Place the tool at a location where
there is no risk of causing a fire (at least 3 meters
away from flammable materials), where it can be
kept under observation and allowed to cool. Contact
Hilti Service after the battery has been allowed to
cool.
The Li-ion battery features a charge status LED dis-
play. The charge status is indicated by the LEDs on the
battery during charging (please refer to the operating
instructions for the charger). 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.
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 dis-
charging 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 neg-
ative 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.
