Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Connecting the Dust Extraction (see figures C–E)
Insert the vacuum connection 20 into the opening of base
plate 9.
Place a vacuum hose 21 (accessory) onto the vacuum con-
nection 20. Connect the vacuum hose 21 with a vacuum
cleaner (accessory). An overview for the connection of vari-
ous vacuum cleaners can be found at the end of these instruc-
tions.
To enable optimum dust extraction, use the splinter guard 22
if possible.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Place the extraction hood 16 onto the contact protector 19.
Splinter Guard (see figure E)
The splinter guard 22 can prevent fraying of the surface while
sawing wood. The splinter guard can only be used with certain
saw blade types and only at a cutting angle of 0°.
Insert the splinter guard 22 into base plate 9 from the front.
The splinter guard 22 can also be fitted with the mounted
plastic sliding shoe 12.
Sliding Shoe (see figure F)
When working with sensitive surfaces, use the plastic sliding
shoe 12.
To put on the plastic sliding shoe 12, place the front edge of
the base plate 9 under the nose of the plastic sliding shoe 23.
Then press the power tool onto the plastic sliding shoe 12 un-
til it engages.
When using the plastic sliding shoe 12, the splinter guard 22 is
inserted not into the base plate 9, but rather the sliding shoe.
Operation

Operating Modes

 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.
Orbital Action Settings
The adjustable orbital action allows for optimal adaptation of
cutting speed, cutting capacity and cutting pattern to the ma-
terial being worked.
The orbital action can be adjusted with the adjusting lever 8,
even during operation.
Orbital action switched off (level 0): No orbital action
Orbital action level I:
Orbital action level II:
Bosch Power Tools
The optimal orbital action setting for the respective applica-
tion can be determined through practical testing. The follow-
ing recommendations apply:
– Select a lower orbital action setting (or switch it off) for a
finer and cleaner cutting edge.
– For thin materials such as sheet metal, switch the orbital
action off.
– For hard materials such as steel, work with low orbital
action.
– For soft materials and when sawing in the direction of the
grain, work with maximum orbital action.
Adjusting the Cutting Angle (see figure J)
The base plate 9 can be swivelled by 45° to the left or right for
mitre cuts.
Remove the vacuum connection 20.
In mitre angle 0° there is a pin in a corresponding recess.
Loosen the screw 24 with the Allen key 29 until you can slide
the base plate 9 in toward the battery 1. Let the pin slide into
the guide groove.
For adjustment of precise mitre angles, swivel the base plate
9 to the desired position according to the scale 25. Every
angle can be adjusted to 45° using a protractor.
Tighten the screw 24 again.
The vacuum connection 20 and the splinter guard 22 cannot
be used for bevel cuts.
Starting Operation
Removing the battery (see figure K)
To remove the battery 1 press the unlocking buttons 2 and
pull out the battery downwards. Do not exert any force.
Switching On and Off
To start the machine, push the On/Off switch 7 forwards.
To switch off the power tool, push the On/Off switch 7 back
to the "0" position.
Controlling the Stroke Rate
With the thumbwheel for stroke rate preselection 4, 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
machine and allow the machine to cool down by running it for
approx. 3 minutes at maximum stroke rate.
Temperature Dependent Overload Protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or not kept within the
permitted battery temperature range, the speed is reduced or
the power tool switches off. At reduced speed, the power tool
will run again at full speed once the permitted battery temper-
ature is reached or the load is reduced. During automatic

shut-down, switch off the power tool, allow the battery to cool

down, then switch the power tool back on.
