Establishing the Cutting Position
The vertical centre mark of cut 12 on the angle
and height stop indicates the centre of the cut
(vertical to the cutting disc). The maximum
width of the cut is indicated by the two marks
11 on the adjustable height stop 10.
For positioning of the height, the horizontal cen-
tre mark of cut 8 on the base plate, which indi-
cates the horizontal centre of the cutting disc, is
helpful.
The direction-of-rotation arrow 14 on the hous-
ing of the power tool indicates the rotation di-
rection of the cutting disc.
Cutting Groove Joints
Examples for the following groove joints are
shown on the graphic pages:
– Corner joints: With the angle stop, see
figure C; with the adjustable height stop, see
figure D
– Mitre joints: With the angle stop, see
figure E; with the adjustable height stop, see
figure F
– Longitudinal and lateral joints: With the an-

Cutting Thin Workpieces (see figure K)
For cutting workpieces with a thickness below
16 mm, place the attachment plate 16 on the an-
gle stop 17. This ensures that the groove is not
cut too close to the upper surface of the work-
piece. When calculating the horizontal cutting
position, consider the 4 mm thickness of the at-
tachment plate.
Also use the attachment plate 16 for mitre joints
in thin workpieces so that the groove is not cut
too deep.
Cutting Narrow Workpieces
If possible, use the adjustable height stop 10
when cutting narrow workpieces. Pay attention
that the marks for the maximum cutting disc
width 11 on the height stop are within the work-
piece.

Maintenance and Service

Maintenance and Cleaning

Before any work on the machine itself, pull
the mains plug.
For safe and proper working, always keep
the machine and ventilation slots clean.
Clean and grease the guides as necessary. Use
exclusively non-gumming oil for this (e. g., sew-
ing machine oil).

and 13 can be readjusted, if required. For this,
loosen and then screw off the clamping lever.
Screw on the clamping lever again displaced by
at least 30° in anticlockwise direction.
