wards) and re-inserted again.
Ejecting the Saw Blade (see figure B)
When ejecting the saw blade, hold the ma-
chine in such a manner that no persons or
animals can be injured by the ejected saw

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.
– 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.
Operation
Starting Operation
Inserting the Battery
Use only original Bosch lithium ion batter-
ies with the voltage listed on the nameplate
of your power tool. Using other batteries can
lead to injuries and pose a fire hazard.
Bosch Power Tools
To protect the machine against unintentional
starting, set the stroke speed selector switch 6
to the centre position. Insert the charged bat-
tery 9 from the front into the handle of the pow-
er tool. Push the battery completely into the
handle until the red stripe can no longer be seen
and the battery is securely locked.

The stroke speed setting of the power tool can
be changed with the stroke speed selector
switch 6. However, this is not possible when the
On/Off switch 7 is pressed.

tion:
The safety lock is activated.
The On/Off switch 7 is blocked and
the machine is secured against being
switched on unintentionally.

1. Gear, low stroke speed.
The low stroke speed is suitable for
sawing hard materials such as steel,
non-ferrous metal, hard plastics or for
precision cuts in wood and plunge
cutting.
The low stroke speed enables sawing
with less vibrations.
Stroke speed selector switch 6 – right:
2. Gear, high stroke speed.
The high stroke speed is suitable for

The high stroke speed enables quick-
er operational progress, e. g., for
coarse cuts in wood.
