Sawing with the base plate
9
offset is possible
only with a mitre angle of 0°. In addition, the
parallel guide with circle cutter
27
(accessory)
as well as the splinter guard
21
may not be used.
Changing the Pre-tension of the Base Plate
With the thumbwheel
23
, the pre-tension of the
base plate clamping lever
24
can be changed.
When the base plate
9
is not seated tightly after
closing the lever, open the clamping lever and
turn the thumbwheel for pre-tension of the base
plate in the
“+”
direction.
When the base plate cannot be adjusted or only
with difficulty after opening the clamping lever,
turn the thumbwheel in the
“
–
”
direction.
Precision Control
Precision Control improves the lateral stability
of the inserted saw blade. The lateral guidance
from the Precision-Control guide cheeks
13
en-
able precise cuts.
To switch on Precision Control, push button
12
.
To switch off Precision Control, press the SDS
lever
19
sideward to the stop and eject the saw
blade
15
. Reinsert the saw blade afterwards, if
required.
f
Wear protective gloves when changing the
saw blade.
The ejected saw blade can be hot.
Precision Control can be used for all applica-
tions, even for mitre cuts. It is especially recom-
mended for cuts in thick wood: The lateral guid-
ance ensures that the cutting angle is
maintained and reduces run-off of the saw blade
(also see “Sawing Thick Wood”, page 25).
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
f
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
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 depressed
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 thumbwheel for stroke rate preselec-
tion
5
, the stroke rate can be preset and
changed during operation.
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.
