9.5 Moving the mitre fence
Ÿ According to regulations, a higher or a lower
workpiece guide face must be available as a stop
depending on the workpiece.
Ÿ Release the rotary knob (4.1) to remove the guide
ruler and replace in the guide groove after rotating

dimensioned so that both a high guide face and
the lower guide face required for flatter
workpieces is available.

The fence ruleris set off on one side by 8 mm.
The cross fence can be moved up to the saw cut to

The fence ruler is set parallel to the saw cut for line-
ar cuts. Use the slide stick (6.1) to push through
narrow workpieces.
To enable the fence to be aligned according to the
scale on the front edge of the table, the zeroes of
the two scales on the left and right are set to the left
and right cutting edge of the saw blade in the works
(7.1).

10.2 General remarks
If dust chips block the suction channel of the lower
protective hood, open the flap (5.6) by a gap of
approx. 8 mm by releasing the rotary knob (5.8)
and remove the blockage.
In the event of serious blockages, or if saw sections
jam, the seals (5.7) can be released with the
enclosed hexagon key so that the flap (5.6) can be
fully opened.
The hexagon key is fastened on the saw blade cover
directly above the flap (5.6).
Attention: disconnect the plug from the mains
before unscrewing the seals.
Once the blockage has been removed reclose the
flap with the seals.

cuts and bring the riving knife into its lower locked
position by pressing down firmly (7.1).
When carrying out concealed cuts make sure of a
good workpiece guidance by pressing the
workpiece firmly onto the table.
Select the sequence of cuts so that sides of the
workpiece which have already been cut are not on
the side facing the fence.
Return the riving knife into its upper position (7.2)
and replace the protective cover on completion of
any concealed cuts.
