Inserting the Saw Blade (see figure A)
 Clean the shank of the saw blade before inserting it.
An unclean shank cannot be fastened securely.
Note: The saw blade 8 can only be inserted when the SDS saw
blade receptacle 9 is open.
For jigsawing, insert the saw blade 8 with the cutting direction
toward the front; for sable sawing, insert the saw blade with
the cutting direction toward the rear. Slide it in the desired
position to the stop in the SDS saw blade receptacle 9, so that
it can be heard to engage.
Note: If you cannot insert the saw blade 8, check if the SDS
saw blade receptacle 9 is open. To open, press the SDS saw
blade receptacle 9 in the direction of the arrow.
 Check the tight seating of the saw blade. A loose saw
blade can fall out and lead to injuries.
Ejecting the Saw Blade (see figure B)
 When ejecting the saw blade, hold the machine in such
a manner that no persons or animals can be injured by
the ejected saw blade.
Press the SDS saw blade receptacle 9 in the direction of the
arrow. The saw blade is released and ejected.
Dust/Chip Extraction
 Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– Provide for good ventilation of the working 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 workplace. Dusts can
easily ignite.
Operation
Starting Operation
Inserting the battery
 Use only original Bosch lithium-ion batteries with the
voltage listed on the nameplate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
Note: Use of batteries not suitable for the machine can lead to
malfunctions of or cause damage to the power tool.
Insert the charged battery 2 into the handle until it can be felt
to engage and faces flush against the handle.
Switching On and Off
To switch on the power tool, first press the lock-off button 4
right or left. Then press the On/Off switch 3 and keep it
pressed.

The power light 5 lights up when the On/Off switch 3 is slightly
or completely pressed, and allows the work area to be illumi-
nated when lighting conditions are insufficient.
To switch off the power tool, release the On/Off switch 3.
To save energy, only switch the power tool on when using it.
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the power tool is switched off by means of a protective
circuit: The inserted tool no longer moves.
 Do not continue to press the On/Off switch after the
machine has been automatically switched off. The bat-
tery can be damaged.
Controlling the Stroke Rate
Increasing or reducing the pressure on the On/Off switch 3
enables stepless stroke-rate control of the switched-on ma-
chine.
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.
Battery Charge-control Indication
The battery charge-control indicator 10 indicates the charge
condition of the battery for a few seconds when the On/Off
switch 3 is pressed half or fully through. It consists of a three-
colour illuminating LED.

Working Advice
 Before any work on the machine itself (e.g. mainte-
nance, 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 working small or thin workpieces, always use a
stable support or a saw station.
For precise work, the power tool can be used as a jigsaw; for
coarse and swift cuts, it can be used as a sabre saw. For jig-
sawing, mount the saw blade with the cutting direction to-
ward the front; for sabre sawing, mount the saw blade with
the cutting direction toward the rear.
Saw with moderate pressure in order to achieve optimal and
precise cutting results.
For long and straight cuts in thick wood, the cutting line can
become inaccurate. In this case, using a Bosch circular saw is
recommended to achieve accurate cuts.
