Sawdust Blower
The sawdust blowing device directs a stream of
air at the saw blade. This prevents the cut line
from being covered by sawdust while working.
The air stream can be adjusted to one of three
levels with adjustment lever 11:
Blower effect switched on:
For working with wood, plastic and
similar materials that produce large
amounts of sawdust.
Blower effect switched off:
For working with metals and when
cooling or lubricating agents are
used.
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 10 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. You can find relevant information in the fol-
lowing table.
Cutting Angle Adjustment
(Figure C)
Before adjusting the cutting angle (e.g.,
for mitre cuts), remove the vacuuming
connector piece 15.
After loosening the screw 18 and lightly sliding in
the direction of saw blade, the base plate 12 is
continuously adjustable to a maximum of 45° to
the right or left.
After coarse adjustment, tighten the screw 18 so
that the base plate 12 can still just be adjusted.
Set the exact cutting angle with the aid of a trian-
gle, for example. Firmly tighten the screw 18.
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 18.
Offsetting the Base Plate
For sawing close to an edge, the base plate can
be offset to the rear.
Loosen the screw 18 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 19 as
well as the splintering protector 17 can-
not be used in this case.
