Personal Protective Equipment; Before Use - Hilti WSR 900-PE Mode D'emploi

e) It is recommended that a ground fault circuit break-
er (RCD) with a maximum rating of 30 mA (max.
30 mA tripping current) is always used.
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
en
free to operate the tool.
c) 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 .
d) In the event of a power faillure, switch the tool off
and unplug the supply cord. This prevents inadver-
tent starting when the power returns.
e) Avoid using extension cords with multiple sockets
and the simultaneous use of several electric tools
connected to one extension cord.
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) Switch the tool off before transporting it.

6. Before use

-NOTE-
The electric supply voltage must comply with the infor-
mation on the type plate.
The cutting edges of the saw blade
●
are sharp.
The cutting edges may present a risk
●
of injury.
Moving parts may present a risk of
●
injury.
Wear protective gloves.

If extension cords are used: Use only extension cords
of a type approved for the intended purpose and of ade-
quate cross section. Failure to observe this point may
result in reduced performance and may cause the cord
to overheat. Replace damaged extension cords. Use only
correspondingly marked and approved extension cords
for working outdoors. Recommended minimum cross
sections and max. cord lengths:

-CAUTION-
f) 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.
g) 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
(see 7.2.2).
h) The cutting produced when sawing, especially metal
cuttings, may be hot. Wear suitable protective
clothing.
i) Never use the tool without the hand guard fitted.
j) 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.
