eyes, or to remain on your skin may promote absorp-
tion of harmful chemicals.
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 bat-
teries and do not subject them to temperatures
over 80°C (176°F).
A risk of fire, explosion or in-
jury through contact 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.
5.3.6 Personal protective equipment
The user and any other persons in the vicinity must
wear ANSI Z87.1-approved eye protection, a hard
hat, ear protection, protective gloves and breathing
protection while the machine is in use.
6 Before use
CAUTION
Wear protective gloves when handling the battery
back.
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.
