Stroke length selector switch 7 - centre posi-
tion:
The safety lock is activated.
The On/Off switch 8 is blocked
and the machine is secured
against being switched on unin-
tentionally.
Stroke length selector switch 7 – left:
Short stroke (19 mm).
The short stroke is suitable for
sawing hard materials such as
steel, non-ferrous metal, hard plas-
tics, precision cuts in wood and for
plunge cutting.
Due to the shorter stroke, sawing
with less vibrations is enabled.
Stroke length selector switch 7 - right:
Long stroke (32 mm).
The long stroke is suitable for
sawing soft materials.
The long stroke increases the ef-
fective cutting length of the saw
blade and enables quicker oper-
ational progress (e. g. for rough
cuts in wood).

Starting Operation

Inserting the Battery
Use only original Bosch O-pack batteries
with the voltage given on the type plate of
your machine. The use of other batteries can
lead to injuries and danger of fire.
Insert the charged battery 10 into the handle un-
til it can be felt to engage and faces flush against
the handle.
Switching On and Off
To release the On/Off switch 8, select the re-
quested stroke length with the stroke length se-
lector switch 7.
To start the machine, press the On/Off switch 8
and keep it depressed.
To switch off the machine, release the On/Off
switch 8.

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.
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 remove them, if required.
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 D–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.
