MAINTENANCE MAIN BROOM Fig. 79 MAIN BROOM To prevent the broom from setting in one direction and to provide the maximum life of the broom it is recommended that the broom be turned end over end periodically. MAIN BROOM ADJUSTMENT KNOB Fig. 80 ADJUSTING THE MAIN BROOM HEIGHT The main broom adjustment knob for changing the sweep height to compensate for broom wear is located in front of the machine as shown in figure 80. Turning the knob to the left (counterclockwise) will lower the main broom.
MAINTENANCE MAIN BROOM ACCESS DOOR Fig. 81 MAIN BROOM ACCESS DOOR The main broom access door is located in front of the left side tire of the machine as shown in figure 81. The door provides access to the main broom for service or inspection. The hopper must be raised to access.

Remove the main broom from the from the broom idler exposing the main broom compartment as shown in figure 86. Check and clean out the main broom compartment before installing the new main broom. Slide the main broom onto the broom idler as shown in figure 87.
MAINTENANCE SIDE BROOM The side broom (Fig. 89) sweeping angle is not adjustable. However, the height of the side broom can be adjusted to compensate as the broom becomes worn from use. Always check and adjust the sweep pattern after changing the side broom. Fig. 89 SIDE BROOM ADJUSTMENT KNOB ADJUSTING THE SIDE BROOM HEIGHT Turn the side broom adjustment knob (Fig. 90) to change the side broom sweep height. Recheck for proper sweep pattern after adjustment.
MAINTENANCE DUST CONTROL PANEL FILTER Fig. 92 Fig. 93 HOPPER The hopper (Fig. 92) houses the debris compartment, the dust control filter and the removable dust baffle. For maximum performance and service life, keep the hopper clean and inspect the seals and flaps daily. Clean the hopper prior to parking the sweeper at the end of the day. A clean hopper will make inspecting the flaps and seals much easier and will prevent premature deterioration of hopper components.
MAINTENANCE DUST FLAPS The dust flaps are very important to sweeping and dust control and are susceptible to damage and should be inspected daily and maintained in good condition. CHECKING THE DUST FLAPS The dust flaps are used on the wheel well, broom chamber and broom door. Inspect the flaps daily and replace any flap that shows signs of wear or deterioration. All flaps should be replaced when worn or damaged to the point that they can no longer perform their normal function.
TROUBLESHOOTING PROBLEM PROBABLE CAUSE REMEDY Machine moves slowly or erratically 1. Battery charge low 2. Brakes dragging 3. Loose connection at foot pedal 4. Drive circuit overloaded 1. Change 2.
