When changing the saw blade, take care
that the saw blade holder is free of material
residue, e. g. wood or metal shavings.
Selecting a Saw Blade
An overview of recommended saw blades can
be found at the end of these instructions. Use
only ½" universal shank saw blades. The saw
blade should not be longer than required for the
intended cut.
The shank thickness of the saw blade must be
0.8–1.6 mm.
Use a thin saw blade for narrow curve cuts.
Inserting the Saw Blade (see figure A)
Press the SDS clamping lever 5 forward and
guide the saw blade 1 behind the clamping plate
8 into the saw blade holder 3. Release the SDS
clamping lever 5.
Check the tight seating by pulling on the
saw blade. A loose saw blade can fall out and
cause injury.
For certain work, the saw blade 1 can also be
turned through 180° (with the teeth pointed up-
wards) and re-inserted again.
Removing the Saw Blade
Before removing, allow the saw blade to
cool down. Danger of injury when touching
the hot saw blade.
Press the SDS clamping lever 5 forward and pull
out the saw blade 1. Release the SDS clamping
lever 5.

Dust/Chip Extraction

Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
Bosch Power Tools
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Prevent dust accumulation at the work-
place. Dusts can easily ignite.
Operation

Operating Modes

Before any work on the machine itself, pull
the mains plug.
Pivoting Footplate (see figure B)
Due to its movability, the adjustable footplate 2
adapts to the required angular position of the
surface.

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.
Switching On and Off
To start the machine, press the On/Off switch 6
and keep it pressed.
To switch off the machine, release the On/Off
switch 6.
Note: For safety reasons, the On/Off switch 6
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 6 enables stepless stroke-rate
control of the switched-on machine.
Light pressure on the On/Off switch 6 results in
a low stroke rate. Increasing the pressure also
increases the stroke rate.
