Sliding Shoe (see figure G)
The plastic guide plate 6 of base plate 7 reduces sensitive sur-
faces from being scratched up. When cutting metal, use the
steel sliding shoe 21.
To mount the steel sliding shoe 21, slide it onto base plate 7
from the front.
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 four orbital action settings allow for optimal adaptation of
cutting speed, cutting capacity and cutting pattern to the ma-
terial being sawed.
The orbital action can be adjusted with the adjusting lever 8,
even during operation.
No orbital action
Small orbital action
Medium orbital action
Large orbital action
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 fin-
er 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 H)
The base plate 7 can be swivelled by 45° to the left or right for
mitre cuts.
Remove the vacuum connection 18.
Loosen screw 22 with Allen key 5 and slide the base plate 7 in
toward the battery 3 to the stop.
For adjustment of precise mitre angles, the base plate has ad-
justment notches on the left and right at 0° and 45°. Swivel
the base plate 7 to the desired position according to the scale
23. Other mitre angles can be adjusted using a protractor.
Afterwards, push the base plate 7 to the stop in the direction
of the saw blade 11.
Tighten the screw 22 again.
The vacuum connection 18 and the splinter guard 20 cannot
be used for bevel cuts.
Offsetting the Base Plate (see figure H)
For sawing close to edges, the base plate 7 can be offset to
the rear.
Loosen screw 22 with Allen key 5 and slide the base plate 7 in
toward the battery 3 to the stop.
Bosch Power Tools
Tighten the screw 22 again.
When sawing with the base plate 7 offset, the parallel guide
with circle cutter 25 as well as the splinter guard 20 may not
be used.

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.
Insert the charged battery 3 from the rear into the base of the
power tool. Press the battery completely into the base until
the red stripe can no longer be seen and the battery is secure-
ly locked.
Switching On and Off
To start the machine, firstly press on the safety switch 1 next
to the symbol to deactivate it. Then press and hold the
On/Off switch 2.
To switch off the machine, release the On/Off switch 2. Acti-
vate the safety switch 1 by pressing on it next to the
symbol .
Note: For safety reasons, the On/Off switch 2 cannot be
locked; it must remain pressed during the entire operation.
Controlling the Stroke Rate
Increasing or reducing the pressure on the On/Off switch 2
enables stepless stroke-rate control of the switched-on ma-
chine.
Light pressure on the On/Off switch 2 results in a low stroke
rate. Increasing the pressure also increases the stroke rate.
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.
Temperature Dependent Overload Protection
When using the machine as intended for, it cannot be subject
to overload. In case of excessive load or when not within the
permitted battery temperature range of 0–70 °C, the speed
is reduced or the machine switches off. With reduced speed,
the machine will not run at full speed again until after reaching
the permitted battery temperature or when the load is re-
duced. In case of automatic shut-off, switch the machine off,
allow the battery to cool down and then switch the machine
on again.
Protection Against Deep Discharging
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
