15. Tension the blades to the belt. Rotate the blades until they contact
the belt. While holding the spring bushing flat on the torque arm,
rotate the torque arm until the pivot arm is against the end of the
slot nearest the pole. Tighten the locking bolts and jam nuts on the
torque arm (Fig. 9). NOTE: The torque arm should be up against
the mounting plate.
16. Set the correct blade tension. Refer to the chart on the pivot shaft bracket (also shown below) for the spring
length required for the belt width. Lightly pull the pivot arm toward the end of the torque arm slot nearest the pole
and turn the adjusting nuts until the required spring length is achieved (Fig. 10). Lock the top adjusting nut.
17. Verify your “C” dimension
to insure the pole is in the correct position.
Test run the cleaner.
Run the conveyor for at least 15 minutes and inspect the cleaning performance. Check the
spring length for proper tensioning. Make adjustments as necessary.
14. Reassemble the spring assembly. Slide the spring, washer and
bushings onto the pivot arm and turn the two adjusting nuts so
about 6mm (1/4") of the pivot arm is exposed above the nuts
(Fig. 8).
