Operation

Operating Modes

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 ad-
justing 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 respec-
tive application can be determined through
practical testing. The following recommenda-
tions 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.
– For soft materials and when sawing in the di-
rection of the grain, work with maximum or-
bital action.
Adjusting the Cutting Angle (see figure C)
The base plate 7 can be swivelled by 45° to the
left or right for mitre cuts.
– Loosen the screw 15 and lightly slide the
base plate 7 in the direction of the saw blade
9.
– 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 7 to the desired position according to
the scale 14. Other mitre angles can be ad-
justed using a protractor.
– Afterwards, push the base plate 7 to the stop
toward the mains cable.
– Tighten the screw 15 again.
The splinter guard 13 can not be inserted for mi-
tre cuts.

Offsetting the Base Plate (see figure D)
For sawing close to edges, the base plate 7 can
be offset to the rear.
– Completely unscrew the screw 15 using the
Allen key 3.
– Take the base plate 7 off and remount it off-
set again so that the screw 15 can be
screwed into the rear bolt hole 17.
– Push the base plate 7 toward the positioning
pin/mark 18 until it engages. Now, tighten
the screw 15 again.
Sawing with the base plate 7 offset is possible
only with a mitre angle of 0°. In addition, the
parallel guide with circle cutter 21 (accessory)
as well as the splinter guard 13 may not be used.
Sawdust Blower Device
With the air jet of the sawdust blower device 5,
the cutting line can be kept free of dust and
chips.
Sawdust-blower setting I:
Low blow effect for sawing in metal and
operation with coolant/lubricant.
Sawdust-blower setting II:
Medium blow effect for sawing materi-
als with low chip removal rate, e. g.,
hardwood.
Sawdust-blower setting III:
Large blow effect for sawing materials
with high chip removal rate, e.g., soft-
wood, plastic, etc.

Starting Operation

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 power tool, push the On/Off switch
4 forwards.
To switch off the machine, push the On/Off
switch 4 toward the rear.
