Before Use - Hilti SCM 22-A Operating Instructions Manual

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
en
with the chuck system and that they are secured
in the chuck correctly.
c) Take care to ensure that metal cuttings do not
find their way into the tool or battery.
d) Empty the chip collector and clean the power
tool before putting it away in the toolbox or other
container for storage or transport. Metal chips may
otherwise fall out of the collector and find their way
into the power tool, battery or charger, presenting a
risk of damage or malfunction.
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 batter-
ies and do not subject them to temperatures over
80°C. This presents a risk of fire, explosion or injury
through contact with caustic substances.

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

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

wear suitable eye protection, a hard hat, ear protec-
