Hilti TE 7-A Operating Instructions Manual page 9

b) Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one
type of battery pack may create a risk of fire when
used with another battery pack.
c) Use power tools only with specifically designated
battery packs. Use of any other battery packs may
create a risk of injury and fire.
d) When battery pack is not in use, keep it away
from other metal objects like paper clips, coins,
keys, nails, screws, or other small metal objects
that can make a connection from one terminal to
another. Shorting the battery terminals together
may cause burns or a fire.
e) Under abusive conditions, liquid may be ejec-
ted from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquids ejected from the battery may cause irrita-
tion or burns.
5.1.6 Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
5.2 Additional safety precautions
5.2.1 Personal safety
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Use auxiliary handles supplied with the tool.
Loss of control can cause personal injury.
c) Always hold the power tool securely with both
hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.
d) Breathing protection must be worn if the power
tool is used without a dust extraction system for
work that creates dust.
e) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
f) Avoid touching rotating parts. Switch the power
tool on only after bringing it into position at
the workpiece. Touching rotating parts, especially
rotating drill bits, discs or blades, etc. may lead to
injury.
g) Activate the safety lock (forward / reverse switch
in the middle position) before storing or trans-
porting the power tool.
5.2.2 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.
5.2.3 Cordless tool 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) Batteries must not be opened or dismantled,
squashed, heated to temperatures over 100°C
or incinerated. A risk of fire, explosion or in-
jury through contact with caustic substances may
otherwise result.
d) 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.
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).
5.2.4 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.
