Controlling/Presetting the Stroke Rate
With the thumbwheel for stroke rate preselection 3, the
stroke rate can be preset and changed during operation.
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. Remove the saw blade from the ma-
chine and allow the machine to cool down by running it for ap-
prox. 3 minutes at maximum stroke rate.
Starting Operation
 Observe correct mains voltage! The voltage of the pow-
er 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.
Switching On and Off
To switch on the power tool, press the On/Off switch 2 and
keep it pressed.
To lock the pressed On/Off switch 2, push the lock-on button
1 toward the right or left.
To switch off the machine, release the On/Off switch 2. When
the On/Off switch 2 is locked, press it first and then release it.
To save energy, only switch the power tool on when using it.
Working Advice
 Before any work on the machine itself, pull the mains
plug.
 When working small or thin work pieces, always use a
sturdy support or a saw table (accessory).
Check wood, press boards, building materials, etc. for foreign
objects such as nails, screws or similar, and remove them,
if required.
Plunge Cutting (see figure D)
 The plunge cutting procedure is only suitable for treat-
ing soft materials such as wood, plaster board or simi-
lar! Do not work metal materials with the plunge cut-
ting procedure!
Use only short saw blades for plunge cutting. Plunge cutting is
possible only with the mitre angle set at 0°.
Place the machine with the front edge of the base plate 6 on
to the workpiece without the saw blade 10 touching the work-
piece and switch on. For machines with stroke rate control,
select the maximum stroke rate. Firmly hold the machine
against the workpiece and by tilting the machine, slowly
plunge the saw blade into the workpiece.
When the base plate 6 fully lays on the workpiece, continue
sawing along the desired cutting line.

Parallel Guide with Circle Cutter (Accessory)
For cuts using the parallel guide with circle cutter 19 (acces-
sory), the thickness of the material must not exceed a maxi-
mum of 30 mm.
Parallel Cuts (see figure E): Loosen the locking screw 18 and
slide the scale of the parallel guide through the lead 17 in the
base plate. Set the desired cutting width as the scale value on
the inside edge of the base plate. Tighten the locking screw
18.
Circular Cuts (see figure F): Set the locking screw 18 to the
other side of the parallel guide. Slide the scale of the parallel
guide through the lead 17 in the base plate. Drill a hole in the
workpiece centred in the section to be sawn. Insert the cen-
tring tip 20 through the inside opening of the parallel guide and
into the drilled hole. Set the radius as the scale value on the in-
side edge of the base plate. Tighten the locking screw 18.
Coolant/Lubricant
When sawing metal, coolant/lubricant should be applied
alongside cutting line because of the material heating up.

Maintenance and Service

Maintenance and Cleaning
 For safe and proper working, always keep the machine
and ventilation slots clean.
Clean the saw blade holder regularly. For this, remove the saw
blade from the machine and lightly tap out the machine on a
level surface.
Heavy contamination of the machine can lead to malfunc-
tions. Therefore, do not saw materials that produce a lot of
dust from below or overhead.
 In extreme conditions, always use dust extraction as
far as possible. Blow out ventilation slots frequently
and install a portable residual current device (PRCD).
When working metals, conductive dust can settle in the in-
terior of the power tool. The total insulation of the power
tool can be impaired.
Lubricate the guide roller 9 occasionally with a drop of oil.
Check the guide roller 9 regularly. If worn, it must be replaced
through an authorised Bosch after-sales service agent.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
