Splinter Guard (see figure B)
Before any work on the power tool itself, pull
the mains plug.
The splinter guard 9 (accessory) can prevent fraying of
the surface while sawing wood. The splinter guard can
only be used for certain saw blade types and only for
cutting angles of 0°. When sawing with the splinter
guard, the base plate 3 must not be moved back for
cuts that are close to the edge.
Press the splinter guard 9 from the bottom into the
base plate 3.
Operation
Operating Modes
Before any work on the power tool itself, pull
the mains plug.
Adjusting the Cutting Angle (see figure C)
The base plate 3 can be swivelled by 45° to the left or
right for bevel cuts.
• Loosen the screws 10 and lightly push the base
plate 3 in the direction of the saw blade 5.
• For adjustment of precise bevel angles, the base
plate has adjustment notches on the left and right at
0° and 45°. Swivel the base plate 3 to the desired
position according to the scale 11. Other bevel
angles can be adjusted using a protractor.
• Afterwards, push the base plate 3 to the stop
toward the power cable.
• Push the assembly plate with the guide roller 4 for-
wards until it faces against the back of the saw
blade and tighten the screws 10 again.
The splinter guard 9 can not be inserted for miter cuts.
Offsetting the Base Plate (see figure D)
For sawing close to edges, the base plate 3 can be off-
set to the rear.
• Completely unscrew the screws 10.
• Lift the base plate 3 off and offset it in such a man-
ner that the front screw 10 can be screwed into the
rear bolt hole 13. The second screw 10 is not
required for sawing with the base plate offset.
• Push the base plate 3 toward the positioning
pin/mark 14 until it engages and slide the assembly
plate with the guide roller 4 forwards against the
saw blade back. Then tighten the screw 10.
Sawing with the base plate 3 offset is possible only
with a bevel angle of 0°. In addition, the parallel guide
with circle cutter 17 (accessory) as well as the splinter
guard 9 may not be used.

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
To start the power tool, press the On/Off switch 2 and
keep it pressed.
To lock the pressed On/Off switch 2, push the lock-on
button 1 toward the right or left.
To switch off the machine, release the On/Off switch
2. When the On/Off switch 2 is locked, press it first and
then release it.
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 maxi-
mum stroke rate.
Controling the Stroke Rate
(GST 65 E/GST 65 BE)
Increasing or reducing the pressure on the On/Off
switch 2 enables stepless stroke-rate control of the
switched-on machine.
Light pressure on the On/Off switch 2 results in a low
stroke rate. Increasing the pressure also increases the
stroke rate.
When the On/Off switch 2 is locked, it is not possible
to reduce the stroke rate.
Working Instructions
When working small or thin work pieces,
always use a sturdy support or a saw table
(accessory).
Check wood, press boards, building materials, etc. for
foreign objects such as nails, screws or similar, and
remove them, if required.
Plunge Cutting (see figure E)
The plunge cutting procedure is only suitable
for working soft materials such as wood, plas-
ter board or similar! Do not work metal mate-
rials with the plunge cutting procedure!
Use only short saw blades for plunge cutting. Plunge
cutting is possible only with the bevel angle set at 0°.
Place the machine with the front edge of the base plate
3 on to the workpiece without the saw blade 5 touching
the workpiece and switch on. For machines with stroke
rate control, select the maximum stroke rate. Firmly hold
the machine against the workpiece and by tilting the
machine, slowly plunge the saw blade into the work-
piece.
When the base plate 3 fully lays on the workpiece, con-
tinue sawing along the desired cutting line.
