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
To start the machine, press the On/Off switch 4
forward.
To switch the machine off, press the On/Off
switch 4 to the rear.
Stroke Rate Preselection
(GST 85 PE/GST 85 PAE/GST 2000)
The required stroke rate can be preselected (also
during operation) using the thumbwheel 2.
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 13 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 adjusted to three levels with the switch 6:
Sawdust blowing level I:
Low airstream, for cuts in metals
and when coolants/lubricants are
used.
Sawdust blowing level II:
Medium airstream, for cuts in mate-
rials with low chip removal rate,
e. g. hardwood.
Sawdust blowing level III:
High airstream, for cuts in materials
with high chip removal rate, e. g.
soft wood, plastic, etc.

Pendulum Action Setting
The four pendulum action settings allow optimum
adaptation of cutting speed, cutting capacity and
cutting pattern to the material being sawed.
The pendulum action can be adjusted in four
steps with the adjustment lever 7. 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.
Adjusting the Cutting Angle
GST 85 PAE: Remove the cover guard 12 and
open the slider 22 at the bottom side of the base
plate.
After loosening the screw 15 and sliding lightly
forward in the direction of the saw blade, the base
plate 8 can be swung to the right or left to a max-
imum of 45°. The angles 0°, 15°, 30° and 45° are
indicated with markings on the scale 14. Interme-
diate settings are also possible.
After coarse adjustment, tighten the screw 15 so
that the base plate 8 can still just be adjusted.
Set the cutting angle using scale 14.
Then tighten the screw 15 again.
To achieve precise cutting angles, the base plate
is fitted with a locking device at 0° and 45° (left
and right). For this, however, the base plate must
be pushed back (towards the motor) to the stop,
so that the notch in the base plate engages in the
positioning pin 18.
