Main broom taper (one end of the main
broom wears more, and so is smaller in
diameter than the other end). This can be
eliminated by adjusting the main broom
bearing blocks.
The sweeper must be on a smooth surface,
and leveled.
1. Remove the main broom.
2. Obtain two equal-size spacer blocks
and place one below the main broom
drive hub.
3. Lower the main broom lever until the
drive hub rests on the spacer block.
4. Replace the main broom mounting plate
and tighten the retaining bolt.
5. Position the second spacer block under
the main broom idler hub.
6. If both broom hubs are in contact with
the spacer blocks then no adjustment
is required. If one of the broom hubs is
in contact with the spacer block, but
the other hub is not, an adjustment is
required.
7. Loosen the two bolts that hold the main
broom bearing block to the adjustment
bracket.
8. Move the bearing blocks up or down
until both broom hubs are in contact
with the spacer blocks.
9. Tighten the two bearing block bolts.
10. Remove the spacer blocks.
11. Reinstall the main broom.
12. Close the main broom.
13. Adjust the main broom.
