Operation

Adjust Cutter Speed

When dispensing a material and glass mixture, the speed at which the cutter spins can be adjusted to ensure the correct ratio of glass to dispensed material.

NOTE: It may be possible to prevent premature anvil and blade wear by slowing the cutter speed and adding an additional strand of roving. See Premature Blade or Anvil Wear on page 7.

1.Determine whether more or less glass is needed.

a.Place bag over cutter chute.

b.Place bag over gun fluid outlet. Try to keep bag away from the dispense outlet to prevent pierc- ing the bag which will lead to inaccurate dis- pense measurements.

c.Dispense a 15-30 second shot.

d.Weigh both bags and calculate ratio.

e.Determine whether more or less glass is needed. Consult material manufacturer recom- mendations for ratio requirements.

f.If ratio is ok, then no adjustment is needed. Oth- erwise, continue with adjustment procedure.

2.Engage trigger lock.

To prevent skin injection, engage the trigger lock before adjusting cutter motor.

3.With the trigger lock engaged, rotate the cutter motor (AH): clockwise to decrease speed, coun- ter-clockwise to increase speed. See FIG. 4.

4.Go to step 1 to test ratio and repeat adjustment as necessary.

5.Tighten the air motor lock down screw to avoid speed changes during operation.

Adjust Anvil to Cutter Head Tension

NOTICE

More tension leads to the anvil and blades wearing out faster. To prevent premature wear and to maxi- mize anvil and blade life, use the minimum tension required to cut the glass and make small increases in tension when strands are not cut correctly.

To cut the glass strands, the blades are pressed against the anvil. If the strands do not appear to be getting cut correctly an adjustment may be needed.

To adjust the tension:

1.Engage trigger lock.

2.Disengage the tension lockdown (AG) by pushing towards the front of the gun.

3.Turn the tension knob (AF) on the cutter: coun- ter-clockwise to increase tension, clockwise to decrease tension. See FIG. 4.

4.Engage tension lockdown.

If there is still excessive anvil or blade wear after per- forming this procedure, see Premature Blade or Anvil Wear on page 7.
