Chopper Adjustment:
Caution: Before adjusting the chopper, the resin, catalyst, and solvent should be
pressurized and operating correctly. Please refer to your operating instructions
before proceeding with the next steps.
NOTE: The chopper can be adjusted vertically and from side to side.
Adjust Chopper Vertically
1. Move the chopper up or down so the glass will enter the spray fan 1.5 to 2 inches
(3.8 to 5.08 cm) in front of the gun nozzle. To move the chopper up or down,
loosen the hex cap screw which connects the chopper mount to the base plate.
Adjust Chopper Horizontally
1. Position the chopper as close to the center of the gun nozzle as possible.
Loosen the large screw on the chopper mount, then insert a screwdriver in the
eccentric stud and turn the stud to actually position the chopper. Retighten the
screw on the chopper mount.
2. Turn the chopper regulator to approximately 1/3 higher psi than the resin pump
pressure.
NOTE: This is only a starting point. Test shots of glass and weighing will
determine the correct pressure to achieve the desired output.
3. The glass should enter the spray fan at the point where the width of the glass
pattern is the same as the width of spray fan.
4. Make a test pass on a flat surface. If the glass is entering the fan to the left or
right of the spray fan, then the chopper is not centered on the spray fan.
5. If the glass is:
A: falling off both sides of the spray fan, then the chopper is set too close to the
spray fan.
B: “lumped” in the middle of the spray fan, then the chopper is set too high
vertically to the spray fan.
