position when jam cutting. The desired cutting depth can be maintained by holding firmly the depth
feed handle on the blade guard. If the full depth of cut requires excessive pressure (on very dense
material e.g.) make 2 or 3 shallow cuts.
5.2.2 Multiple step cutting
Multiple step cutting consists of moving the conveyor cart with the material to be cut back and forward
under the rotating blade,

Place the material to be cut on the conveyor cart firmly against the guide-a-cut and the backstop,
keeping the hands well away from the blade.

Move conveyor cart forward near the blade and pull down the cutting head until blade is lowered
to a point where it will lightly contact the surface of the material.

Then pass the material beneath with rapid full length strokes, taking a shallow cut (approximately
3 mm deep as shown on the picture) on the forward. On the backward stroke, lift the blade just
clear over the cutting line.

Complete each rapid stroke backward and forward by passing the material beyond the centre of
the blade before starting the reverse movement of the conveyor cart.
NOTE: the harder the material, the more rapid should be the forward and backward strokes.
Step cutting lessens the area of the blade circumference in contact with the material, keeping the
blade cool, running free and cutting at peak efficiency.
5.2.3 Cutting thicker material
You can cut thicker material by reversing the material on the cart. In order to raise the head to pass
the material under it, you have to slide the upper head stop from position 1 to position 2 as shown on
the picture 4. You can then cut up to 300mm thick material. If you want to cut again fewer than 110mm,
turn the stop from position 2 to position 1.
