SWEEPING SYSTEM
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 30 hours of operation.
The main broom should be replaced when the bristles are worn to a length of 2-1/2 inches (6.35 cm). The main broom stop (JJ) must be re-adjusted
when the broom is replaced. NOTE: Bristle length on a new broom is 3-1/4 inches (8.25cm).
NOTE: The machine should be stored with the Main Broom in the raised position.
To Rotate or Replace the Main Broom...
WARNING!
The battery pack must be disconnected when performing this procedure.
1 Turn the Key Switch (MM) OFF.
2 Put the Main Broom Raise / Lower (ON / OFF) Lever (II) in the DOWN position.
3 Open the Main Broom Right Access Door (38) .
4 See Figure 5.1. Remove the large T-Bolt (A) from the side of the broom idler arm. Pivot the idler arm assembly out of the main broom core.
5 Pull the main broom 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 (B) on the broom drive hub (left side
of machine) engage the slots in the broom core.
7 Swing the idler arm assembly back into the broom core and re-install the T-Bolt that holds the idler arm in place.
8 Close and latch the Main Broom Right Access Door (38) .
To Adjust the Main Broom Height...
1
Drive the machine to an area with a level floor and set the parking brake (GG) .
2 Pull the Main Broom Raise / Lower (ON/OFF) Lever (II) back and slide to the right and up to lower the main broom. Push lightly on the front of
the Drive Pedal (OO) to start the main broom rotating. DO NOT move the machine.
3 Let the main broom run in place for 1 minute. This allows the broom to polish a “strip” on the floor. After 1 minute, raise the broom, release the
parking brake and move the machine so that the polished strip is visible.
4 Inspect the polished strip on the floor. If the strip is less than 2 inches (5.08 cm) or more than 3 inches (7.62cm) wide, the broom needs to be
adjusted.
5 To adjust, loosen the Main Broom Adjust Knob (JJ) and slide forward or backward to lower or raise the Main Broom. The farther the Knob (JJ)
travels up in the slot, the lower the Main Broom will be. Tighten Knob (JJ) after adjustment is complete.
6 Repeat steps 1-5 until the polished strip is 2-3 inches (5.08-7.62cm) wide. The width of the polished strip should be the same at both ends of
the broom. If the strip is tapered, move the machine to a different area and follow steps below “To Level the Main Broom”.
To Level the Main Broom...
1
Follow the steps “To Adjust the Main Broom
Height” and determine if the taper is larger
on the right or left side of the broom.
2 See Figure 5.2. Loosen the lock nut on Bolt
(C) , then loosen the two Screws and Nyloc
Nuts (D and E) for the right pillow block
Bearing (F) .
3 If the taper is larger on the right side raise
the Adjuster Weldment (G) , if the taper is
larger on the left side lower the Adjuster
Weldment (G) .
4 Tighten the lock nut on the adjustment Bolt
(C) , Nyloc nuts, and screws, and then run
the broom.
5 Check the polished strip left by broom, if the
broom strip is not even all the way across,
repeat the above steps.
