GUTTER BROOM
The Model 600 utilizes a vertical digger design enabling the gutter broom to remove heavy de-
bris from the gutter and transfer it in front of the pick-up head. The gutter broom is also designed
such that it will fold under the cab if run into the curb or any other stationary object.
The gutter broom is controlled from inside the cab with an electric toggle switch located on the
control console panel. The sweeper auxiliary engine must be running in order for the gutter
broom(s) to work. When the toggle switch control is shifted in the DOWN position, the gutter
broom rotational speed is directly related to the sweeper auxiliary engine RPM. As the engine
RPM is increased, gutter broom rotation increases.
Always use care when gutter broom is down. Never back up with broom down or broom could
hang on stationary object resulting in severe damage!
WARNING : Never work on or near rotating gutter broom or exit cab with
gutter broom down and rotating.
A. ADJUSTMENTS
1. 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 back-
ing off the eye bolt nut (2) used to attach spring to the boom arm. However, when
new bristles are installed onto gutter broom, the spring must be re-tensioned to
counter the increased weight of the new bristles. Failure to reset the spring eye bolt
nut will result in premature wear of the gutter broom bristles. Proper position of the
eye bolt nut for new segments is approximately one-half way up the eye bolt.
2. Tilt - there is no established dimension for setting the gutter broom tilt because
street curbs and gutters vary from place to place. Located on the end of the boom
arm are the gutter broom wrist and hand. The hand adjustment allows forward tilt;
the wrist allows side to side tilt. Both require a 15/16" wrench to release locking bolts.
To adjust the hand two bolts are found behind the torque motor (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 Drawing on Page 17 for best results.
