harmful. Contact with or inhalation of the dust may
cause allergic reactions and/or respiratory diseases
to the operator or bystanders. Certain kinds of dust
are classified as carcinogenic such as oak and beech
dust especially in conjunction with additives for wood
conditioning (chromate, wood preservative). Material
containing asbestos must only be treated by special-
ists. Where the use of a dust extraction device is
en
possible it shall be used. To achieve a high level
of dust collection, use a suitable vacuum cleaner
of the type recommended by Hilti for wood dust
and/or mineral dust together with this tool. Ensure
that the workplace is well ventilated. The use of a
dust mask of filter class P2 is recommended. Fol-
low national requirements for the materials you
want to work with.
m) Do not lift or carry the tool by the accessories
attached to it.
5.2.2 Careful use of the power tool
Check that the insert tools used are compatible with
the chuck system and that they are secured in the
chuck correctly.
5.2.3 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.
5.2.4 Battery tool use and care
a) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.

6 Before use

6.1 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
20
b) Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over
80°C. A risk of fire, explosion or injury through con-
tact with caustic substances may otherwise result.
c) Do not use batteries other than those approved
for use with the applicable power tool or appli-
ance. Use of other batteries or use of the battery for
purposes for which it is not intended presents a risk
of fire and explosion.
d) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
e) Avoid short-circuiting the battery. Check that the
terminals on the battery and in the power tool
are free from foreign objects before inserting the
battery in the power tool. Short circuiting the bat-
tery terminals presents a risk of fire, explosion and
chemical burns.
f) 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).
g) 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.
5.2.5 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.
5.2.6 Personal protective equipment
The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protec-
tion and protective gloves while the power tool is in
use.
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.
