MAIN BROOM MAINTENANCE

Since the Main Broom Motor always turns in the same direction, the bristles on the broom eventually become curved, reducing sweeping
performance. Sweeping performance can be improved by removing the broom and turning it around (end-for-end). This procedure, known as
"rotating" the main broom, should be done once every 15-20 hours of operation.
The main broom should be replaced for optimal performance when the bristles are worn to a length of 2-1/2 inches (6.35 cm). The main broom
stop must be re-adjusted when the broom is replaced. NOTE: Bristle length on a new broom is 3-3/4 inches (9.5 cm).
NOTE: The machine should be stored with the Main Broom in the raised position.
WARNING!
The engine must not be running when performing this procedure.
To Rotate or Replace the Main Broom:
1. Turn the Ignition Key Switch (A) OFF.
2. Open the Main Broom Access Door (36).
3. See Figure 17. Move aside the right side skirt (EF).
4. Pivot the Idler Arm Assembly (EG) out of the main broom core. NOTE: The Idler Arm is held in place by the Main Broom Access Door (36).
5. Pull the Main Broom (EH) out of the broom housing and remove any string or wire wrapped around it. Also inspect the skirts at the front,
back and sides of the broom housing. The skirts should be replaced or adjusted if they are torn or worn to a height of more than 1/4 inch
(6.35 mm) off the ground.
6. Turn the broom around (end-for-end) and slide it back into the broom housing. Make sure that the lugs on the broom core (left side) engage
the slots in the broom drive hub and that the broom is fully seated.
7. Swing the idler arm assembly back into the broom core. NOTE: Make sure the lugs on the idler arm engage the slots in the broom core
8. Move the right side skirt (EF) back into position being sure to press the skirt over the two Pins (EJ).
9. Close and latch the Main Broom Access Door (36).
10. If you are replacing a used broom with a new broom go to the Main Broom Maintenance section to readjust the broom height.
