MAIN BROOM ADJUSTMENT
Standard (Chain) Suspension
To adjust the main broom contact area with a chain
suspension (Figure SP-11), take the following steps.
1. Lower the main broom on a flat, level surface.
2. Adjust the spring tension on one side as neces-
sary using the chain. For example, if the left
side shows more wear (or taper) than the right
side, shorten the chain on the left side to raise
the left side of the broom.
Hydraulic Suspension
In the optional hydraulic main broom suspension
(Figure SP-12), the snubbing spring is compressed
or released to adjust for even broom wear. The fac-
tory adjustment for the left side is approximately
3.75 in, for the right 1.25 in. This counterbalances
the added weight of the drive motor on the right
side.
If the left side shows more wear than the right
side, raise the left side.
To adjust the main broom contact area with the
optional hydraulic suspension, use the following
procedure:
1. Lower the main broom on a flat, level surface.
