SWEEPING SYSTEM SERVICE
MAIN BROOM
To prevent the broom from “setting” in one direction and to provide the maximum life of the broom it is recom-
mended that the broom be turned end over end periodically.
CHECKING THE MAIN BROOM SWEEP PATTERN
Check the main broom sweep pattern after changing the broom or when poor sweeping performance is encoun-
tered while sweeping.
1. While the machine is not moving, lower the main broom to the “SWEEP” position and let machine sweep in
one spot for a short period of time.
2. Before moving the machine, raise main broom lever to the “UP” position and move the sweeper forward
enough to see the pattern left by the main broom bristles on the floor.
3. Check the width of the pattern on the floor to determine if the main broom requires adjustment.
-A normal sweep pattern left on the floor will be between 1 and 2 inches wide.
-A pattern that is more than 2 inches wide indicates the broom linkage needs to be adjusted “UP.”
-A pattern that is less than 1 inch wide indicates the broom linkage needs to be adjusted “DOWN.”
ADJUSTING THE MAIN BROOM HEIGHT
When changing the sweep height adjustment it is recommended that the bolt be adjusted 1 turn at a time. After
adjustment, recheck the sweep pattern to determine if further adjustment is necessary.
-Turn the adjustment knob counterclockwise to INCREASE the sweep pattern width.
-Turn the adjustment knob clockwise to DECREASE the sweep pattern width.
REPLACING THE MAIN BROOM
The Main Broom should be replaced when the bristles become worn to less than 2". The main broom is held in
place by the right side broom door. This feature provides for easy removal and installation of the main broom
without the need for special tools or equipment. Follow the instructions below for main broom removal &
replacement.
1. Park sweeper on a smooth level surface, engage parking brake, turn key switch to “O”, place the main
broom lever in the “SWEEP” position.
2. Lift the door latch to open the right side broom door.
3. Swing the broom drive idler hub out to clear the main broom.
4. Remove the broom from the broom compartment.
5. Install the replacement broom. Pay special attention to the slots on the broom, it may be necessary to
rotate the broom so the tabs on the drive hub align with the slots on the broom.
6. Swing the idler hub to engage the main broom and close the access door. Check the door latch for proper
engagement when closed.
7. Check the Main Broom sweep pattern and adjust as necessary.
MAIN BROOM LEVEL ADJUSTMENT
The main broom level is factory set and should not need adjustment. If the level becomes out of adjustment and
the broom bristle contact pattern is not an even 1" to 2" wide, the broom arm lift frame will need to be adjusted.
The frame is supported by two plates located inside the broom doors. The carriage bolts that secure the plates
to the frame will need to be loosened. The frame can then be leveled and the bolts re-tightened.
