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) 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 General advice for the cutting
Material weighing under 30 kg and having dimensions smaller than 600x500x265mm can be cut
with the CM70 ALU.
Before commencing work make sure tools are firmly seated!
Select the right tools as recommended by the manufacturer depending on the material to be
worked, the working procedure (wet cut) to be carried out and the required efficiency.
Apply cooling water continuously whilst cutting and in good time!
When cutting work is finished, close the water-tap so you can remove the cut pieces from the
conveyor cart without getting wet.
If the thermal protection trips, wait a few minutes to allow the motor to cool down before
restarting the machine.
In case of the triggering of the thermal protection, press the black button on the switch (230V
motor) .
