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 adap-
tation of cutting speed, cutting capacity and cutting
pattern to the material being sawed.
The orbital action can be adjusted with the adjusting
lever 10, 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 test-
ing. 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.
– For soft materials and when sawing in the direction
of the grain, work with maximum orbital action.
Adjusting the Cutting Angle (see figure E)
The base plate 8 can be swivelled by 45° to the left or
right for mitre cuts.
Remove the dust cover 17 and the vacuum connec-
tion 6.
Release the clamping lever 23 of the base plate and
lightly push the base plate 8 toward the mains cable.
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 8 to the desired position
according to the scale 21. Other mitre angles can be
adjusted using a protractor.
Afterwards, push the base plate 8 to the stop in the
direction of the saw blade 14.
Close the base plate clamping lever 23 to lock the
base plate in the adjusted position.
The dust cover 17, vacuum connection 6 and splinter
guard 20 cannot be used for mitre cuts.

Offsetting the Base Plate (see figure F)
For sawing close to edges, the base plate 8 can be
offset to the rear.
Remove the dust cover 17 (see "Dust Cover",
page 36).
Release the clamping lever 23 of the base plate and
push the base plate 8 toward the mains cable to the
stop.
Close the base plate clamping lever 23 to lock the
base plate in the adjusted position.
Sawing with the base plate 8 offset is possible only
with a mitre angle of 0°. In addition, the parallel guide
with circle cutter 26 (accessory) as well as the splinter
guard 20 may not be used.
Changing the Pre-tension of the Base Plate
With the thumbwheel 22, the pre-tension of the base
plate clamping lever 23 can be changed.
When the base plate 8 is not seated tightly after clos-
ing 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 Pre-
cision-Control guide cheeks 12 enable precise cuts.
To switch on Precision Control, push button 11. To
switch off Precision Control, press the SDS lever 18
sideward to the stop and eject the saw blade 14.
Reinsert the saw blade afterwards, if required.
Wear protective gloves when changing the
saw blade. The ejected saw blade can be hot.
Precision Control can be used for all applications,
even for mitre cuts. It is especially recommended for
cuts in thick wood: The lateral guidance ensures that
the cutting angle is maintained and reduces run-off of
the saw blade (also see "Sawing Thick Wood",
page 38).
Sawdust Blower Device
With the air jet of the sawdust blower device 9, 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 9 to position "I".
Switching off the sawdust blower device: For cuts in
metal and when a dust extraction system is con-
nected, push the switch 9 to position "0".
