RS guns with a cutter installed have two modes of oper-
ation. 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.
Premature Blade Cartridge or
Anvil Wear
NOTICE
More tension between the anvil and blade cartridge
leads to the anvil and blade cartridge wearing out
faster. To prevent premature wear and to maximize
anvil and blade cartridge life, use the minimum ten-
sion required to cut the glass and make small
increases in tension when strands are not cut cor-
rectly. See Adjust Anvil to Blade Cartridge Ten-
sion, page 7.

The two most common causes of premature anvil or
blade cartridge wear are excessive tension between the
anvil and blade cartridge and excessive cutter speed.
See page 7 for the Adjust Anvil to Blade Cartridge
Tension procedure.
To reduce the cutter speed while keeping the same
glass output, perform the following procedure:
1. Do a bag check to establish a baseline for the cur-
rent 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
3. If necessary, rotate counter-clockwise to increase
speed.
5. Do another bag check to determine the new glass
output.
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.
