Ejecting the Saw Blade (see figure A2)
u When ejecting the saw blade, hold the machine in
such a manner that no persons or animals can be
injured by the ejected saw blade.
Turn the SDS lever 12 toward the front in the direction of the
contact protector 9. The saw blade is released and ejected.
Splinter Guard (see figure B)
The splinter guard 13 (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 5
must not be moved back for cuts that are close to the edge.
Press the splinter guard 13 from the bottom into the base
plate 5.
Dust/Chip Extraction
u Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one's health. Touching or breathing-in the dusts can
cause allergic reactions and/or lead to respiratory
infections of the user or bystanders. Certain dusts, such
as oak or beech dust, are considered as carcinogenic,
especially in connection with wood-treatment additives
(chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
u Prevent dust accumulation at the workplace. Dusts
can easily ignite.
Operation
Operating Modes
u Before any work on the machine itself, pull the mains
plug.
Orbital Action Settings
The four orbital action settings allow for optimal adaptation
of cutting speed, cutting capacity and cutting pattern to the
material being sawed.
The orbital action can be adjusted with the adjusting lever 6,
even during operation.
Setting 0
No orbital action
Setting I
Small orbital action
Setting II
Medium orbital action
Setting III
Large orbital action
The optimal orbital action setting for the respective
application can be determined through practical testing. The
following recommendations apply:
– Select a lower orbital action setting (or switch it off) for a
finer and cleaner cutting edge.
– For thin materials such as sheet metal, switch the orbital
action off.
– For hard materials such as steel, work with low orbital
action.

Manual GST 75 E Professional.indd 19
– For soft materials and when sawing in the direction of the
grain, work with maximum orbital action.
Adjusting the Cutting Angle (see figure C)
For adjustment of precise mitre angles, the base plate has
adjustment notches on the left and right at 0° and 45°.
Swivel the base plate 5 to the desired position according
to the scale 14. Other mitre angles can be adjusted using a
protractor.
Afterwards, push the base plate 5 to the stop in the direction
of the saw blade 8.
Tighten the screw 15 again.
The splinter guard 13 can not be inserted for mitre cuts.
Offsetting the Base Plate (see figure C)
For sawing close to edges, the base plate 5 can be offset to
the rear.
Loosen the screw 15 and slide the base plate 5 to the stop
toward the mains cable.
Tighten the screw 15 again.
Sawing with the base plate 5 offset is possible only with a
mitre angle of 0°.The splinter guard 13 may not be used.
Starting Operation
u 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
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 1 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.
Controlling/Presetting the Stroke Rate
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.
With the thumbwheel for stroke rate preselection 2, 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.
After longer periods of work at low stroke rate, the machine
can heat up considerably. Remove the saw blade from the
machine and allow the machine to cool down by running it for
approx. 3 minutes at maximum stroke rate.
Working Advice
u Before any work on the machine itself, pull the mains
plug.
