) After extended use of the PBC, the rollers and
bearing will need to be replaced. Fischbein offers the
rollers with the bearings mounted in the roller. To
replace the rollers, follow these steps:
1. Turn “OFF” and lock out the electrical and
pneumatic supplies to the PBC machine.
2. Remove the rear and front channel shrouds. Also
remove the top channel cover, which is near the
drive motor.
3. Loosen each of the two, ½ inch socket cap screws,
which act as the shafts for the compression roller
assemblies. (

REAR CHANNEL
:
To move the compression roller away from the
compression belt, the block adjustment screw (
C
)
must be turned into the block, after the jam nut is turned. (
Illustration 8.9
) This will allow
the block to be moved away from the belt.
FRONT CHANNEL
:
To move the front compression roller away from the belt, the adjustment screw (
A
) must be
turned clockwise into the block. This will pull the block from the center of the machine so
the roller mechanism can be replaced. (
