c) When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another. Shorting the battery terminals together may
cause burns or a fire.
d) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact acci-
en
dentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejec-
ted from the battery may cause irritation or burns.
5.1.6 Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
5.2 Hammer safety warnings
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Use auxiliary handles, if supplied with the tool.
Loss of control can cause personal injury.
c) Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring. Cutting ac-
cessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give
the operator an electric shock.
5.3 Additional safety precautions
5.3.1 Personal safety
a) Always hold the power tool securely with both
hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.
b) Breathing protection must be worn if the power
tool is used without a dust removal system for
work that creates dust.
c) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
d) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotat-
ing insert tools, may lead to injury.
e) Activate the safety lock (forward / reverse switch
in the middle position) before storing or trans-
porting the power tool.
f) When restarting after the electronic overload pro-
tection system has switched the tool off, care
must be taken to ensure that the power tool is held
securely with both hands on the grips provided.
g) Children must be instructed not to play with the
power tool.
h) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
i) Dust from material such as paint containing lead,
some wood species, minerals and metal may be
harmful. Contact with or inhalation of the dust may
22
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
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.
5.3.2 Power tool use and care
a) Secure the workpiece. Use clamps or a vice to
secure the workpiece. The workpiece is thus held
more securely than by hand and both hands remain
free to operate the power tool.
b) Hold power tool by insulated gripping surfaces
when performing an operation where the fastener
may contact hidden wiring or its own cord. Fasten-
ers contacting a "live" wire may make exposed metal
parts of the power tool "live" and could give the
operator an electric shock.
c) Check that the insert tools used are compatible
with the chuck system and that they are secured
in the chuck correctly.
5.3.3 Cordless tool use and care
a) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
b) Do not expose batteries to high temperatures or
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. A risk of fire, explosion or injury through con-
tact with caustic substances may otherwise result.
d) 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.
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 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.
