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 solid object.
The gutter broom is controlled from the 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 is engaged 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. Maximum gutter broom rotation of 100 RPM is
achieved at 2000 RPM engine speed.
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, never exit cab with
gutter broom down and rotating.
A. ADJUSTMENTS
1. Spring - a long spring is used to counter-balance the gutter broom assembly (1).
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 onto gutter broom, the spring must be re-tensioned
to counter the increased weight of the new bristles. Failure to retention 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.
2. 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 Model 600 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
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 Page 30
for best results.
