Pendulum Action Setting
The saw blade pendulum action
that is adjustable in four steps
makes possible the optimum adap-
tation of sawing advancing (cutting
speed), cutting performance and
cut appearance of the material to
be worked.
For each downward movement, the saw blade is
lifted off the material which facilitates sawdust
ejection, reduces heat generated by friction and
increases the service life of the saw blade. At the
same time, the reduction of the necessary ad-
vancing force makes fatigue-free working possi-
ble.
The adjustment lever 8 makes possible the ad-
justment of the pendulum action in four steps.
The switching can take place with the machine
running:
Step 0:
No pendulum action
Step I:
Small pendulum action
Step II:
Medium pendulum action
Step III:
Large pendulum action
The following basic recommendations are to
be observed:
– The finer and cleaner the cut edge should be,
the smaller the pendulum step selected should
be or switch off.
– For the working of thin material such as sheet
metal, switch off the pendulum action (Step 0).
– In hard material such as steel, work with a
small pendulum action.
– In materials such as softwood and cutting in
the direction of the grain, the maximum pendu-
lum action can be used.
The optimal setting can be determined in prac-
tice.

Cutting Angle Adjustment
(Figure
Before adjusting the cutting angle (e.g.,
for mitre cuts), remove the vacuuming
connector piece 13.
After loosening the screw 16 and lightly sliding in
the direction of saw blade, the base plate 11 is
continuously adjustable to a maximum of 45° to
the right or left.
After coarse adjustment, tighten the screw 16 so
that the base plate 11 can still just be adjusted.
Set the exact cutting angle with the aid of a trian-
gle, for example. Firmly tighten the screw 16.
When returning the base plate to the 0° (normal)
position, press the base plate lightly in the direc-
tion of the motor until it can be felt to engage and
again tighten the screw 16.
Offsetting the Base Plate
For sawing close to an edge, the base plate can
be offset to the rear:
Loosen the screw 16 by approx. two turns. Slide
the base plate to the rear in the direction of the
motor to the stop and retighten the screw.
With the base plate offset, only the 0° (nor-
mal) position can be used.
The circle cutter/parallel guide 18 as
well as the splintering protector 17 can-
not be used in this case.
Splintering Protector
(see figure
The splintering protector 17 prevents the splinter-
ing of the surface when sawing in wooden mate-
rials.
Press the splintering protector from below into
the base plate 11.
The splintering protector cannot be
used for certain saw blade types (e.g.,
saw blades with set).
Glide Shoe for Base Plate
(see figure
The aluminium base plate 11 with a steel inlay
provides the highest possible stability and is in-
tended for the working of metal or insensitive sur-
faces without the use of the glide shoe 12.
