Initial Operation
Observe correct mains voltage: The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.
Switching On and Off
GST 135 BCE
To start the machine, press the On/Off switch 3
and keep it depressed.
To lock on, push the lock-on button 2 to the left
or right while the On/Off switch 3 is pressed.
To switch off the machine, release the On/Off
switch 3 or push and release it then.
GST 135 CE
To start the machine, press the On/Off switch 3
forward.
To switch the machine off, press the On/Off
switch 3 to the rear.
Electronic Soft Start
The electronic soft start feature increases the
service life of the motor and the mechanical
transmission. After brief soft starting, the ma-
chine reaches the preselected stroke speed.
Constant Electronic Control
The constant electronic control keeps the stroke
speed at no-load and under load almost constant;
this ensures uniform operation feed and an even
cutting pattern.
Stepless Stroke-speed Control
(GST 135 BCE)
Lightly pressing the On/Off switch 3 results in low
stroke speed. Applying more pressure increases
the stroke speed.
Stroke Rate Preselection
The required stroke rate can be preselected (also
during operation) using the thumbwheel 4.
1 – 2 = low stroke rate
3 – 4 = medium stroke rate
5 – 6 = high stroke rate
The required stroke rate is dependent on the ma-
terial and the working conditions and can be de-
termined by a practical trial.
After working for longer periods at low stroke rate
allow the machine to cool down by running it at
maximum stroke rate and no-load for approx.
3 minutes.

Contact Protector
The contact protector 16 attached to the housing
prevents unintentional contact with the saw blade
while working and should not be removed.
Sawdust Blower Device
The sawdust blower device leads an air jet to the
saw blade. The air jet keeps sawdust from cover-
ing the cutting line during operation.
The air flow can be switched on or off with the
switch for the sawdust blowing device 9:
Pendulum Action Setting
The pendulum action can be adjusted in four
steps with the adjustment lever 10. Switching is
possible with the machine running:
Step 0:
Step I:
Step II:
Step III:
Recommendations:
– The more narrow and clean the cutting edge
should be, the lower the pendulum action level
should be selected (or switched off).
– For thin materials, e. g. sheet metal, switch the
pendulum action off.
– For hard materials, e. g. steel, work with low
pendulum action.
– For soft materials and when sawing in the di-
rection of the grain, work with maximum pen-
dulum action.
The optimal setting can be determined by practi-
cal testing.
English - 3
Blower effect switched on:
For working with wood, plastic and
similar materials that produce large
amounts of sawdust.
Blower effect switched off:
For working with metals and with
use of coolant/lubricant as well as
when using dust/chip extraction.
The four pendulum action settings
allow optimum adaptation of cutting
speed, cutting capacity and cutting
pattern to the material being
sawed.
No pendulum action
Small pendulum action
Medium pendulum action
Large pendulum action
