2. Install cutter:
a. If necessary, use a crescent wrench to adjust
pivot (541) so that it is parallel to gun front end
and the open end points to the front of the gun.
See F

4. Adjust anvil to blade tension:
a. Release lockdown (AG). See F
IG. 1 on page 4.
b. Adjust tension knob (AF) as desired.
c. Tighten lockdown (AG).
d. Release idler lock down screw (AN).

b. Back out screws (630). See F
IG. 3.
c. Install cutter onto pivot so glass feed holes are
on top.
NOTE: Ensure proper engagement of o-ring (542) into

FIG. 4
RS guns with a cutter installed have two modes of operation. When the trigger is pulled halfway, material sprays
but the cutter is not activated. When the trigger is pulled
all the way, the air motor in the cutter is started and
glass begins dispensing.
AJ
AC
1. Do a bag check to establish a baseline for the current cutter output.
a. Weigh a bag.
b. Dispense glass into the bag for 15 or 30 sec-
onds depending on the output.
c. Weigh the bag to determine glass output. This
is your fiberglass output baseline.
2. Add another strand of roving to the cutter inlet.
3. Engage trigger lock.
To prevent skin injection, engage the trigger lock
before adjusting cutter motor.
4. With the trigger lock engaged, rotate the cutter
motor (AH) clockwise to decrease speed. See F
4. If necessary, rotate counter-clockwise to increase
speed.
5. Do another bag check to determine the new glass
output.
IG.
Premature Blade or Anvil Wear
NOTICE
More tension between the anvil and blades leads to
the anvil and blades wearing out faster. To prevent
premature wear and to maximize 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. See Adjust Anvil to
Cutter Head Tension, page 8.
The most common causes of premature anvil or blade
wear are excessive tension between the anvil and
blades, excessive cutter speed, and excessive tension
between the idler wheel and anvil. See page 8 for the
Adjust Anvil to Cutter Head Tension procedure.
To reduce the cutter speed while keeping the same
glass output, perform the following procedure:
332574D 7
a. Weigh a bag.
a. Dispense glass into the bag for the same
amount of time as in step 1b.
b. Weigh the bag to determine glass output.
6. If the weight does not match the baseline bag
weight, adjust the cutter speed then do another bag
check. Repeat until the new bag weight matches the
baseline bag weight.
Anvil and Blade Replacement
See Replace Anvil and Replace Blades procedures on
pages 11 and 12.
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 piercing the bag which will lead to inaccurate dispense 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 recommendations for ratio requirements.
f. If ratio is ok, then no adjustment is needed. Oth-
erwise, continue with adjustment procedure.
Adjust Anvil to Cutter Head Tension
NOTICE
More tension leads to the anvil and blades wearing
out faster. To prevent premature wear and to maximize 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: counter-clockwise to increase tension, clockwise to
decrease tension. See F
4. Engage tension lockdown.
If there is still excessive anvil or blade wear after performing this procedure, see Premature Blade or Anvil
Wear on page 7.
IG. 4.
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, counter-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.
8 332574D
IG. 4.
Operation
Adjust Anvil to Idler Tension
To adjust the anvil (AC) to idler (AJ) tension, the idler
position can be adjusted. See F
1. Follow Pressure Relief Procedure found within the
RS Gun and Cutter, Operation-Repair manual.
2. Engage trigger lock.
3. Remove cover (627). See page 20.
4. Loosen idler lockdown screw (617) using 3/16 in.
hex key.
5. Slide idler to desired position.
6. Tighten idler lockdown screw to lock idler in position.
IG. 4 on page 7.
Adjust Blower Air
NOTE: Blower air adjustment only applies to cutters
shown in F
The cutter has blower air to help keep the anvil cool and
to keep the inside of the cover free of debris. The blower
air has been factory set to optimize performance of the
cutter, however it can be adjusted.
IG. 1, page 4.
Adjust Cutter Air Pressure
Adjust the incoming air pressure according to the table
below.
Number of
Strands US Metric
One Strand 50-75 psi 3.4-5 bar, 0.3-0.5 MPa
Two Strands 80-125 psi 5.5-8.6 bar, 0.6-0.9 MPa
Three Strands 80-125 psi 5.5-8.6 bar, 0.6-0.9 MPa
Use a 3/32 hex allen key to turn adjusting screw (635)
counter-clockwise to allow more air flow into the inside
of the cover on the cutter assembly. This will affect air
motor performance as less air will go to the air motor
resulting in slower cutter speeds.
