When the On/Off switch 3 is locked, it is not possible to re-
duce the stroke rate.
With the thumbwheel for stroke rate preselection 2, 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.
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.
Contact Protector
The contact protector 9 attached to the casing prevents acci-
dental touching of the saw blade during the working proce-
dure and may not be removed.
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 5 on
to the workpiece without the saw blade 8 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 5 fully lays on the workpiece, continue
sawing along the desired cutting line.
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
 Before any work on the machine itself, pull the mains
plug.
 For safe and proper working, always keep the machine
and ventilation slots clean.
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.

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 residual current device (RCD). When work-
ing metals, conductive dust can settle in the interior of the
power tool. The total insulation of the power tool can be im-
paired.
Lubricate the guide roller 7 occasionally with a drop of oil.
Check the guide roller 7 regularly. If worn, it must be replaced
through an authorised Bosch after-sales service agent.
