Utility Hook (see figure D)
Your tool is equipped with a utility hook 6 for
hanging it, e. g., to a ladder, etc. Simply fold out
the utility hook 6 to the required position.
When the tool is hanging by the utility hook,
ensure that the saw blade is protected
against unintended contact. Danger of inju-
ry.
Fold the utility hook 6 back in again when you
are ready to continue working.

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 8 and then press the
On/Off switch 7 and keep it pressed.
To switch off the machine, release the On/Off
switch 7.
Note: For safety reasons, the On/Off switch 7
cannot be locked; it must remain pressed during
the entire operation.
Orbital action
To achieve a high cutting speed, the orbital ac-
tion is continuously in operation.
Constant Electronic Control
The constant electronic control keeps the
stroke rate almost constant at no-load and un-
der load, and ensures uniform working perform-
ance.
Controlling/Presetting the Stroke Rate
Increasing or reducing the pressure on the
On/Off switch 7 enables stepless stroke-rate
control of the switched-on machine.
Bosch Power Tools
Light pressure on the On/Off switch 7 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.

Working Advice

Tips
When sawing light building materials, ob-
serve the statutory provisions and the rec-
ommendations of the material suppliers.
Check wood, press boards, building materials,
etc. for foreign objects such as nails, screws or
similar, and always 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 figure E)
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.
