b) Always wear protective gloves when starting and
operating the power tool.
c) Breathing protection must be worn if the power
tool is used without a dust removal system for
work that creates dust.
d) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
e) 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.
Do not direct the lamp either at yourself or at
f)
anyone else. Do not, under any circumstances,
look into the lamp. There is a risk of dazzling
yourself and causing damage to the retina of the
eye.
g) Activate the safety lock (forward / reverse selector
switch in the middle position) or pull the battery
out slightly until it engages in the first position
before making adjustments to the tool or before
fitting drill bits, the side handle or depth gauge
and before storing or transporting the tool.
h) 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.
i)
Children must be instructed not to play with the
power tool.
j)
The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
k) Whenever the power tool is knocked or dropped,
check its operation and, if necessary, do not con-
tinue to use it.
l)
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
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) 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) Ensure the switch is in the off position before
inserting battery pack. Inserting the battery pack
into power tools that have the switch on invites
accidents.
b) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
c) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.
d) 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.
e) 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.
f)
Do not use excessive force when fitting or remov-
ing the battery.
g) 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).
h) 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.
i)
Avoid ingress of dampness.Dampness may cause
a short circuit resulting in a risk of burning injury or
fire.
j)
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.
5.3.4 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.
5.3.5 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.
c) If the work involves breaking right through, take
the appropriate safety measures at the opposite
side. Parts breaking away could fall out and / or fall
down and injure other persons.
