Cutter Assembly
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.
Adjust Cutter Speed
When dispensing a material and glass mixture, the
speed at which the cutter spins can be adjusted to
ensure the ratio of glass to dispensed material.
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 (AJ): clockwise to decrease speed, coun-
ter-clockwise to increase speed. See F
. 11.
4.
Go to step 1 to test ratio and repeat adjustment as
necessary.
Adjust Anvil to Blade Cartridge Tension
To cut the glass strands, the blade cartridge is pressed
against the anvil. If the strands do not appear to be get-
ting 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
. 11.
4.
Engage tension lockdown.
NOTE:
More tension leads to the anvil and blade car-
tridge wearing out faster. Do not apply more tension
than is necessary.
