Starting Operation
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
The "Power Light" 10 is lit when the mains plug
is inserted, and allows for illumination of the
working range under unfavourable light condi-
tions.
Switching On and Off
To start the machine, first push the lock-off but-
ton for the On/Off switch 7 and then press the
On/Off switch 8 and keep it pressed.
To switch off the machine, release the On/Off
switch 8.
Note: For safety reasons, the On/Off switch 8
cannot be locked; it must remain pressed during
the entire operation.
Controling the Stroke Rate
Increasing or reducing the pressure on the
On/Off switch 8 enables stepless stroke-rate
control of the switched-on machine.
Light pressure on the On/Off switch 8 results in
a low stroke rate. Increasing the pressure also
increases the stroke rate.
The required stroke rate is dependent on the
material and the working conditions and can be
determined by a practical trial.
Reducing the stroke rate is recommended when
the saw blade engages in the material as well as
when sawing plastic and aluminium.
After longer periods of work at low stroke rate,
the machine can heat up considerably. Allow the
machine to cool down by running it for approx.
3 minutes at maximum stroke rate.
Working Advice
Tips
When sawing light building materials, ob-
serve the statutory provisions and the rec-
ommendations of the material suppliers.
Bosch Power Tools
Check wood, press boards, building materials,
etc. for foreign objects such as nails, screws or
similar, and allways use the correct sawblade.
Switch the machine on and guide it toward the
workpiece. Position the footplate 2 onto the sur-
face of the work and saw through the material
applying uniform contact pressure and feed. Af-
ter completing the working procedure, switch
the machine off.
If the saw blade should jam, switch the machine
off immediately. Widen the gap somewhat with
a suitable tool and pull out the machine.
Plunge Cutting (see figures E–F)
The plunge cutting procedure is only suita-
ble for treating soft materials such as wood,
plaster board or similar! Do not work metal
materials with the plunge cutting proce-
dure!
Use only short saw blades for plunge cutting.
Place the machine with the edge of the footplate
2 onto the workpiece and switch on. For power
tools with stroke speed control, set the maxi-
mum stroke speed. Press the power tool firmly
against the workpiece and allow the saw blade
to slowly plunge into the workpiece.
As soon as the footplate 2 fully lays on the sur-
face of the workpiece, continue sawing along-
side the desired cutting line.
For certain work, the saw blade 1 can also be in-
serted turned through by 180° and the sabre
saw can be guided accordingly in a reversed
manner.
Flush Cuts (see figure G)
Using elastic bimetal saw blades, items still at-
tached to a wall (e. g. projecting building ele-
ments such as water pipes, etc.) can be sawn off
flush at the wall.
Pay attention that the saw blade always ex-
tends beyond the diameter of the material
being worked. There is danger of kickback.
Position the saw blade directly against the wall
and apply some lateral pressure via the tool until
the footplate faces against the wall. Switch the
power tool on and saw through the workpiece,
applying constant lateral pressure.
