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
en
correctly.
c) Large and heavy insert tools must only be operated in first
gear. There is otherwise a risk that the tool will be damaged
when it is switched off or, under unfavorable conditions, the
chuck might be detached.
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) Do not expose batteries to high temperatures or fire. This
presents a risk of explosion.
c) Do not disassemble, squash or incinerate batteries and do
not subject them to temperatures over 80°C. A risk of fire,
explosion or injury through contact with caustic substances
may otherwise result.
d) Avoid ingress of dampness.Dampness may cause a short
circuit resulting in a risk of burning injury or fire.
e) Do not use batteries other than those approved for use
with the applicable power tool or appliance. 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) Observe the special instructions applicable to the trans-
port, storage and use of Li-ion batteries.
g) 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 battery terminals presents a risk of fire, explosion
and chemical burns.
h) Do not charge or continue to use damaged batteries (e.g.
batteries with cracks, broken parts, bent or pushed-in
and/or pulled-out contacts).
Hold power tool by insulated gripping surfaces when per-
i)
forming an operation where the fastener may contact hid-
den wiring or its own cord. Fasteners contacting a "live" wire
may make exposed metal parts of the power tool "live" and
could give the operator an electric shock.
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. Exposure to
dust at a poorly ventilated workplace may result in damage to
the health.
