OPERATING THE SCORING BLADE (OPTIONAL)
0 The scoring saw unit is specially used for
cutting double side plastic covered
panels.
The scoring blade always rotates
simultaneously with the main saw-blade.
The position of the scoring blade is
determined by the place of the pressure
pad. The pressure pad has to touch the
material at all times when cutting. In the
most forward position the scoring blade
will be approx. 3 mm out of the pressure
pad.
Check the direction of rotation of the scoring
blades. See the arrows on the pressure pad
(Fig. 32).
ADJUSTING SCORING BLADES
FRONT/BACKWARDS
1 The scoring blade is operated with the
delivered 5 mm allen key.
2 Put the key in the hexagon insert screw in
the middle of the cover Fig. 32).
3 Turn the key clockwise. The scoring unit
locks in its backwards position.
4 Turn the key anti clockwise; the scoring
unit moves, under spring pressure, to its
forward position.
ADJUSTING THE WIDTH OF THE GROOVE
1 Open the cover of the saw unit.
2 Remove the scoring blades. Use the
delivered 5 mm allen key for the shaft
and the spanner 19/24 mm for the
hexagon nut (Fig. 33).
3 Adjust the scoring blades with the
delivered spacers.
4 Mount the scoring blades on the spindle.
Watch the direction of rotation (see
pressure pad).

width of the groove in regard to the main
saw-blade.
