Connecting the Dust Extraction (see figures D–E)
Insert the vacuum connection 20 into the opening of base
plate 7.
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.
Splinter Guard (see figure F)
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°. When saw-
ing with the splinter guard, the base plate 7 may not be offset
to the rear for sawing close to edges.
Insert the splinter guard 22 into base plate 7 from the front.
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 23.
To mount the steel sliding shoe 23, slide it onto base plate 7
from the front.
Operation

Operating Modes

Orbital Action Settings
The four orbital action settings allow for optimal adaptation
of cutting speed, cutting capacity and cutting pattern to the
material 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
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.
Bosch Power Tools
Adjusting the Cutting Angle (see figure H)
(only GST 18 V-LI B)
The base plate 7 can be swivelled by 45° to the left or right for
mitre cuts.
Remove the vacuum connection 20.
Loosen screw 24 with hex 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
25. 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 10.
Tighten the screw 24 again.
The vacuum connection 20 and the splinter guard 22 cannot
be used for bevel cuts.
Offsetting the Base Plate (see figure H)
(only GST 18 V-LI B)
For sawing close to edges, the base plate 7 can be offset to
the rear.
Loosen screw 24 with hex key 5 and slide the base plate 7 in
toward the battery 3 to the stop.
Tighten the screw 24 again.
The splinter guard 22 must not be used when sawing with the
base plate 7 offset.

Starting Operation

Inserting the battery
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 se-
curely locked.
Starting and Stopping (GST 18 V-LI B)
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.
To save energy, only switch the power tool on when using it.
Starting and Stopping (GST 18 V-LI S)
To start the machine, push the On/Off switch 2 forward so
that the "1" is indicated on the switch.
To switch off the machine, push the On/Off switch 2 toward
the rear so that the "0" is indicated on the switch.
Controlling 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.
