section is long enough to take up the length of
the drive spindle.
h) The workpiece must be fixed securely in place.
i) Do not use cutting discs for grinding.
j) Take steps to ensure that flying sparks from the
tool do not present a hazard, i.e. by striking your-
self or other persons or by igniting inflammable
substances. Adjust the position of the disc guard
en
accordingly.
k) When working in dusty conditions, check to en-
sure that the cooling air openings remain unob-
structed. Should it become necessary to remove
dust deposits from the air openings, first unplug
the tool from the electric supply and then use a
non-metallic object to remove the dust, taking
care to avoid damaging parts inside the tool.
l) If the nut securing the disc and flange is not
tightened firmly, the disc may work loose from
the spindle due to the braking effect of the motor.
Tighten the disc / flange securing nut in accordance
with the directions given in the operating instructions.
Wait until the disc comes to a standstill.
5.6.3 Electrical safety
a) 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.
b) Dirty or dusty power tools that have been used fre-
quently for work on conductive materials should
be checked at regular intervals at a Hilti Service
Center. Under unfavorable circumstances, damp-
ness or dust adhering to the surface of the tool,
especially dust from conductive materials, may lead
to damage to the tool.
5.6.4 Battery use and care
a) Observe the special guidelines applicable to the
transport, storage and use of Li-ion batteries.

6 Before use

WARNING
Never use the power tool without the guard.
6.1 Battery use and care
NOTE
Battery performance drops at low temperatures. Use the
tool only after fully charging the battery. This ensures
that maximum battery capacity is available. Change to
a second battery as soon as a drop in performance is
26
b) Do not expose batteries to high temperatures and
keep them away from fire. This presents a risk of
explosion.
c) Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over
80°C. This presents a risk of fire, explosion or injury
through contact with caustic substances.
d) Use only batteries of the type approved for use
with the applicable power tool. Use of unapproved
batteries or use of the batteries in areas of application
for which they are not approved presents a risk of
fire and explosion.
e) Do not charge or continue to use damaged bat-
teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).
f) If the battery is too hot to touch it may be defective.
Place the tool in a location where it can be kept
under observation, well away from flammable ma-
terials, and allow it to cool down. Contact Hilti
Service after the battery has cooled down.
5.6.5 Work area safety
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.

5.6.6 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

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.
