Rotor Disassembly
4. Loosen the two Socket Cup Point Set Screws (7102-14-6), and slide the 8-Blade
Rotor Assembly (5103-03-01) off of the Air Motor (8402-1-1) shaft.
NOTE: Be very careful when handling the Rotor Assembly as the blades are sharp
and could cause injury.
5. Loosen the Socket Flat Head Screws (7102-13-6) used to secure the Wedge Inserts
(5103-29-1), and remove the Chopper Blades (9210-1-1) from the 8-Blade Wedge
Rotor Assembly (5103-03-01).
Super Cutter Assembly
NOTE: The sharp edge of the Chopper Blades should be slightly dulled by stropping
them on cardboard prior to installation into Rotor Assembly. This intentional dulling
of the blades by the whetting process will avoid slicing and nicking of the Rubber
Roll and will assure longer life of both Blades and Rubber Roll.
Rotor Assembly
1. Insert Chopper Blades (9210-1-1) between the Rotor Hub (5103-28-1) and Wedge
Insert (5103-29-1). The back edge of the Blade must be bottomed against the Rotor.
2. Align the edges of the blade with the end of the Rotor Hub (5103-28-1). Tighten the
Socket Flat Head Screw (7102-13-6) in the Wedge Insert (5103-29-1) to secure the
blades in place.
3. Wipe a small amount of grease on the Air Motor (8402-1-1) shaft.
4. Slide the Wedge Rotor Assembly (5103-03-01) onto the Air Motor (8402-1-1) shaft,
so the Set Screws (7102-14-6) in the Rotor Hub (5103-28-1) ride on the flat of the
chopper motor shaft.
NOTE: The rotor must be positioned on the Air Motor shaft so it aligns with the
Rubber Roll.
Rubber Roll Assembly
1. Press the Rubber Roll (5103-6-1) onto the Mandrel Assembly (5103-5-01). Secure
the Rubber Roll by inserting the E-Ring (7205-3-31) into the groove in the Mandrel.
2. Insert the Mandrel/Rubber Roll Assembly into the top of the T-Slot on the Base
Plate (5103-1-1). Align the Slide Adjust Nut (5103-4-1) with the T-Slot.
3. Slide Rubber Roll Assembly toward the Wedge Rotor Assembly (5103-03-01) and
tighten the Socket Head Cap Screw (7102-2-20).
