5.2.1 Full depth or fixed cutting
In full depth or fixed cutting, the cutting head is locked in a fixed position and the material is pushed
into it as shown.
•
Lower the cutting head to the desired cutting depth (in “through cutting”, lower cutting head until
blade periphery reaches max. 3mm under the surface of the conveyor cart) by means of the
handle on the blade guard
•
Fix position by tightening the clamping device
•
Put material on conveyor cart
•
Push the conveyor cart slowly and without undue pressure towards the rotating blade and cut
the material as shown on the picture.
NOTE: While recommended, it is not absolutely necessary to lock the cutting head into a given
depth 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
