2. CAB-OVER
a. Spring - a long spring (1) is used to counter-balance the gutter broom assembly.
As the gutter broom bristles wear out, this spring tension must be reduced by
backing off the eye bolt nut (2) used to attach spring to the boom arm. However,
when new bristles are installed on gutter broom, the spring must be re-tensioned
to counter the increased weight of the new bristles. Failure to re-tension the
spring eye bolt nut will result in premature wear of the gutter broom bristles.
Proper tension of the eye bolt nut for new segments is approximately one-half
way up the eye bolt.
b. Tilt - there is no established dimension for setting the gutter broom tilt because
street curbs and gutters vary from place to place. To tilt the gutter broom, located
on the end of the boom arm are the wrist and hand. The hand adjustment allows
forward tilt; the wrist allows side to side tilt. Both require a 15/16" wrench to re-
lease locking bolts. To adjust the hand, two bolts are found behind the torque mo-
tor (3). Two bolts lock the wrist adjustment: one bolt is found on each side of
the wrist bracket (4). When setting the gutter broom tilt, approximate the new
bristle contact pattern for best results.
