5.3.3 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.
5.3.4 Battery 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 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.
d)
Use only batteries that are approved for use with
the applicable tool or appliance.
Use of unap-
proved batteries or use of the batteries for areas of
application for which they are not approved 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.
5.3.5 Work area
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.
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.
5.3.7 Safety precautions
Do not switch the power tool on if the saw blade,
the blade guard or the pivoting guard are not fitted
correctly.
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 the heat of the sun, on a
radiator or behind glass, e.g. at a window. Batteries that
have reached the end of their life must be disposed of
safely and correctly to avoid environmental pollution.
Insert the battery in the corresponding charger.
6.2 Charging the battery
DANGER
Use exclusively the specified Hilti batteries and Hilti
battery chargers listed under “Accessories”.
DANGER
Ensure that the outer surfaces of the battery are
clean and dry before inserting it in the correspond-
ing charger. Read the operating instructions for the
charger for further information about the charging
procedure.
