f)
Use only the Hilti chargers listed under “Acces-
sories”.
g)
Ensure that the outer surfaces of the battery are
clean and dry before inserting it in the corre-
sponding charger. Read the operating instruc-
tions for the charger for further information about
the charging procedure.
h) If the battery gets too hot to touch, this may indicate
that it is faulty.
Place the tool in a location where
it can be kept under observation, well away from
flammable materials, and allow it to cool down.
Contact Hilti Service after the battery has been
allowed to cool.
6.2.5 Electrical safety
Before beginning work, check the working area (e.g.
using a metal detector) to ensure that no concealed
electric cables or gas and water pipes are present.
External metal parts of the power tool may become
live, for example, when an electric cable is damaged
accidentally. This presents a serious risk of electric shock.
6.2.6 Work area safety
Ensure that the workplace is well ventilated.
Exposure
to dust at a poorly ventilated workplace may result in
damage to the health.
6.2.7 Personal protective equipment
The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protec-
tion, protective gloves and breathing protection while
the tool is in use.
7 Before use
DANGER
Wear protective gloves when changing insert tools as
the insert tools get hot during use.
7.1 Changing the saw blade
CAUTION
Wear protective gloves.
The cutting edges of the saw
blade teeth are sharp. The cutting edges may present a
risk of injury.
7.1.1 Fitting the saw blade

connection end (fig. 3).
4. Turn the blade holder locking sleeve counterclock-
wise and hold it in this position.
5. Push the saw blade into the blade holder from the
front end of the tool.

4. Pull the blade forward out of the blade holder.
5. Release the locking sleeve and allow it to move back
to its original position.
7.2 Battery use and care
NOTE
Battery performance drops at low temperatures. Never
use the battery until the cells become fully discharged.
Change to the second battery as soon as a drop in per-
formance is noticed. Recharge the battery immediately
so that it is ready for reuse.
Store the battery in a cool, dry place. Never store the
battery where it is exposed to direct sunlight or sources
of heat, e.g. on heaters / radiators or behind a motor
vehicle windscreen. Batteries that have reached the end
of their life must be disposed of safely and correctly to
avoid environmental pollution.
