Operation; Stroke Rate - Hilti WSR 650-A Manual De Instrucciones

7. Operation

The cutting edges of the saw blade
●
are sharp.
The cutting edges may present a risk
●
of injury.
Wear protective gloves.
●
The sawing operation swirls up dust
●
and wood chips into the air.
The dust and wood chips may be harm-
●
ful to the eyes and respiratory system.
Wear protective goggles and breath-
●
ing protection.
Operation of the tool creates noise.
●
Excessive noise may damage the
●
hearing.
Wear ear protection.
●
-NOTE-
To ensure good cutting performance and ease the load
●
on the tool, use only saw blades that are in good con-
dition.
Do not overload the tool.
●
-CAUTION-
When working, always guide the tool away from the
●
body.
Lift the tool away from the workpiece only once the
●
blade has come to a standstill.
Do not lay the tool down before the blade has come
●
to a standstill.
The saw blade becomes hot when
●
used for long periods.
There is a risk of burning if the blade
●
is touched.
Wear protective gloves.

7.1 Switching on
Press the switch interlock and then press the control
switch.
7.1.1 Switching off
Release the control switch.

7.2 Stroke rate

7.2.1 Adjusting the stroke rate
The recommended stroke rate can be selected by turn-
ing the stroke rate regulator.
When the control switch is pressed the tool will then run
at the pre-selected speed. The electronic speed control
system maintains an almost constant stroke rate even
under load. The recommended stroke rate settings and
information concerning the correct choice of saw blade
can be found in the product information and in the cor-
responding table of applications.
7.2.2 Recommended stroke rates
(1 = low stroke rate, 6 = high stroke rate)
Material to be cut
Wood
Wood with embedded nails
Interior finishing, drywall
Plastic
Steel
Non-ferrous metals
Aluminum
Stainless steel
The above settings are recommendations intended to
ensure optimum cutting performance. The optimum set-
ting may differ from these recommendations depend-
ing on the saw blade used, the electric supply voltage
and on how the tool is used. Setting the wrong stroke
rate may cause the saw blade to wear more quickly.
7.3 Orbital action
Use of the orbital action can increase cutting perfor-
mance in certain materials such as wood or wood mate-
rials. The orbital action can be switched on or off by
moving the orbital action selector switch as far as it will
go in each position. Move the switch only when the motor
has stopped.
