TABLE SAW RIVING KNIFE ADJUSTMENT
MODEL: W660
It is possible that the factory setting of the riving knife restricts the maximum cutting
depth of the saw. If this is the case, the riving knife can be adjusted as follows:
1) Ensure that the machine is isolated from the power supply.
2) Raise the blade to its maximum height using the blade height adjustment hand
wheel at the front of the saw.
3) Remove the hose from the crown guard, remove the crown guard from the riving
knife, by loosening the black thumb screw.
4) In order to keep the Crown Guard parallel to the table, once the riving knife has
been adjusted, a slight modification will be needed to the plastic part.
Extend by 7mm

This allows the crown guard to rotate further on the pivot point and remain parallel to
the table after the adjustment. Use a sharp craft knife, carefully extend the slot at the
rear of the guard by approximately 7mm. You might find this easier if the two sides of
the guard are first split.
5) Slide the carriage fully forward to expose the riving knife attachment nut.
6) The nut holding the riving knife can now be loosened using a 16mm spanner.
7) Raise the riving knife and crown guard assembly, so that the crown guard is
situated just above the top of the saw blade. If necessary adjust the riving knife so
that there is an even gap between the leading edge of the riving knife and the radius
of the saw blade. Adjust the crown guard so that it is parallel to the table.
8) Re-tighten the bolt.
The saw can now be used to the full cutting capacity.
