Additional Safety Precautions - Hilti WSR 650-A Mode D'emploi

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 ejected
from the battery; avoid contact. If contact acciden-
tally occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from
the battery may cause irritation or burns.
5.1.6 Service
a) Have your power tool serviced by a qualified repair
person using only genuine replacement parts. This
will ensure that the safety of the power tool is main-
tained.

5.2 Additional safety precautions

5.2.1 Personal safety
a) Wear ear protection. Excessive noise may lead to a
loss of hearing.
b)Always hold the tool securely, with both hands on
the grips provided. Keep the tool, especially its grip
surfaces, clean and free from oil and grease.
c)Wear respiratory protection when the work causes
dust.
d)Exercise your fingers during pauses between work
to improve the blood circulation in your fingers.
e)Switch the tool on only once it has been brought into
the working position close to the workpiece.
f) Operate the tool only as directed and only when it
is in faultless condition.
g)Wear protective gloves when changing insert tools.
The insert tool may become hot during use.
h) Avoid unintentional starting. Do not carry the tool
with your finger on the on/off switch. Disconnect
the tool from its battery pack when the tool is not in
use, during pauses between work, before mainte-
nance, when changing insert tools and during trans-
port.
5.2.2 Work area
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Poor-
ly ventilated workplaces may be injurious to the health
due to exposeure to dust.
5.2.3 Electrical safety
a) Before beginning work, check the working area
(e.g. with a metal detector) to ensure that no con-

cealed electric cables or gas and water pipes are
present. External metal parts of the tool may become
live if, for example, an electric cable is damaged
inadvertenly. This presents a serious risk of elec-
tric shock.
5.2.4 Power tool use and care
a) Secure the workpiece. Use clamps or a vice to hold
the workpiece in place. The workpiece is thus held
more securely than by hand and both hands remain
free to operate the tool.
b) Ensure that the insert tools used are equipped with
the appropriate connection end system and that
they are properly fitted and secured in the chuck.
5.2.5 Special safety precautions for
reciprocating saws
a) When cutting, always guide the tool away from the
body.
b) Never place your hands in front of or on the saw
blade.
c) Do not cut unknown base materials. The blade may
cause the tool to kick back if it strikes a hidden object.
d) To ensure efficient and safe operation, the contact
shoe of the tool must be pressed against the work-
piece.
e) Always use saw blades of adequate length. To avoid
kick-back while sawing, the blade must always pro-
ject at least 40 mm beyond the workpiece during the
stroke cycle.
f) When using the pipe cutting adaptor (accessory),
especially when cutting large-diameter pipes, apply
only moderate pressure and select a suitable cut-
ting speed in order to avoid overheating the tool.
g) The cutting produced when sawing, especially metal
cuttings, may be hot. Wear suitable protective
clothing.
h) Never use the tool without the hand guard fitted.
i) Before beginning work, find out the hazard class of
the dust produced by the work. Use only an indus-
trial vacuum cleaner with an officially approved pro-
tection classification in compliance with your local
dust control regulations for work with the tool.
5.2.6 Battery tool use and care
a)Use only the batteries listed in these operating
instructions (see section 6).
b)Ensure that the outer surfaces of the battery are clean
and dry before inserting it in the corresponding
charger.
c)Check that the battery is securely attached to the
tool. A falling battery could injure you or other persons.
d)The batteries must be disposed of correctly on reach-
ing the end of their life (see section 10).
e) Pay attention to the supply cord when using the belt
adaptor. It increases the risk of tripping or catching
on things.
f) Do not charge or continue to use damaged batter-
ies (e.g. batteries with cracks, broken parts, bent
or pushed-in and/or pulled-out contacts).
