Graco 332574D - RS Gun Cutter Assemblies Manual De Usuario

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. 

3.

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

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.

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 F

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.

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

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.
