Replacing/Inserting the Saw Blade
Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as
during transport and storage, remove the
battery from the power tool. There is danger
of injury when unintentionally actuating the
On/Off switch.
When mounting the saw blade, wear protec-
tive gloves. Danger of injury when touching
the saw blade.
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
Use only saw blades suitable for the material be-
ing worked.
An overview of recommended saw blades can
be found at the beginning of these operating in-
structions. Use only saw blades with single-nose
shank. The saw blade should not be longer than
required for the intended cut.
Use a thin saw blade for narrow curve cuts.
Inserting the Saw Blade (see figure A)
Press the red SDS clamping lever 4 forward and
guide the saw blade 1 behind the clamping plate
11 into the saw blade holder 3. Release the SDS
clamping lever 4.
Check the tight seating of the saw blade. A
loose saw blade can fall out and lead to injuries.
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
Press the red SDS clamping lever 4 forward and
pull out the saw blade 1. Release the SDS
clamping lever 4.

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.
Bosch Power Tools
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.
– 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.

Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as
during transport and storage, remove the
battery from the power tool. There is danger

ed with the stroke length selector switch 7.
However, this is not possible when the On/Off
