Sawdust Blower Device
With the air jet of the sawdust blower device 10,
the cutting line can be kept free of dust and
chips.
Switching on the sawdust blower device: For
cuts in materials with high removal rate, such as
in wood, plastic, etc., push the switch 10 to
position "I".
Switching off the sawdust blower device: For
cuts in metal and when a dust extraction system
is connected, push the switch 10 to position "0".
Starting Operation
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the type plate of the
power tool.
Switching On and Off (GST 135 CE)
To start the machine, push the On/Off switch 3
forwards.
To switch off the machine, push the On/Off
switch 3 toward the rear so that the "0" is indi-
cated on the switch.
Switching On and Off (GST 135 BCE)
To start the machine, press the On/Off switch 3.
To lock the On/Off switch 3, keep it pressed and
push the lock-on button 2 to the right or left.
To switch off the machine, release the On/Off
switch 3. When the On/Off switch 3 is locked,
press it first and then release it.
Controling the Stroke Rate (GST 135 BCE)
Increasing or reducing the pressure on the
On/Off switch 3 enables stepless stroke-rate
control of the switched-on machine.
Light pressure on the On/Off switch 3 results in
a low stroke rate. Increasing the pressure also
increases the stroke rate.
When the On/Off switch 3 is locked, it is not
possible to reduce the stroke rate.

Presetting the Stroke Rate
With the dial control for stroke rate preselection
5, the stroke rate can be preset and changed
during operation.
1 – 2:
Low stroke rate
3 – 4:
Medium stroke rate
5 – 6:
High 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 aluminum.
After longer periods of work at low stroke rate,
the machine can heat up considerably. Remove
the saw blade from the power tool and allow the
machine to cool down by running it for approx.
3 minutes at maximum stroke rate.

Working Instructions

When working small or thin work pieces,
always use a sturdy support or a saw table
(accessory).
While working, hold the machine by the handle
4 and guide it alongside the desired cutting line.
For precise cuts and quiet running, guide the
machine additionally with the other hand by the
plastic cap 1.
Contact Protector
The contact protector 16 attached to the casing
prevents accidental touching of the saw blade
during the working procedure and may not be
removed.
Sawing Thick Wood
For straight cuts in thick wood, please observe
the following recommendations:
– Switch on Precision Control for lateral guid-
ance of the saw blade (see "Precision Con-
trol", page 11).
– Use Bosch saw blades marked with "Preci-
sion for Wood".
– Adjust the precise mitre angle using an angle
measurer.
