Align Rubber Roll with Blade Rotor
1. Be sure rubber roll and blade rotor align properly.
2. The blade rotor should lightly rub against the rubber roll when held still. The
rubber roll should exert just enough pressure against the blade rotor to turn the
rotor.
NOTE: If the blades press too hard against the rubber roll, the rubber roll will
need to be replaced more often.
NOTE: The rubber roll may not be perfectly round, adjust to the middle point not
the high or low point.
3. Adjust the idler (also called the “bearing or sleeve roll”) and the rubber roll until
the idler is barely touching the rubber roll.
NOTE: Turn the roller eccentric nuts clockwise to tighten the roller.
NOTE: The idler should be just close enough to the rubber roll to pull the
fiberglass into the chopper without pulling the glass too tightly.
4. When you have properly aligned the rubber roll, blade rotor, and idler roll, tighten
them into position by using the eccentric nuts on the back of the base plate.
Note: It will be necessary to periodically readjust the chopper as rubber roll
becomes worn.
Reinstall Chopper Cover
1. Slide the chopper cover extension (sideways) onto the front bottom lip of the
chopper cover.
2. Attach the cover to the chopper, aligning the base plate’s notch with the boss in
the cover. Twist the cover stud to lock the cover in place.
WARNING: Never operate the chopper unless the cover is installed, or personal
injury may result.
