To Remove the Main Broom, To Install the Main Broom

MAINTENANCE

MAIN BROOM (Refer to the Main Broom Group and Main Broom Lift Group in the Parts section)

FOR SAFETY: The main broom and the vacuum impeller automatically begin to operate when the main broom lever is positioned in the forward end of its slot.

The main broom spans the width of the machine, and sweeps debris into the hopper. Inspect the main broom daily for wear or damage. Remove any obstructions found in the main broom chamber, main broom drive hub or idler hub.

The main broom should be replaced when the remaining bristles measure 5/8 “ (16mm) or less in length.

NOTE: All original equipment brooms are equipped with “Perform Alert™”. This feature tells the operator when it is time to replace the main broom. “Perform Alert™” brooms have bright yellow tufts located on each end of the broom. These tufts are pre-trimmed to indicate the length of a worn out broom. When the main body of the broom wears to a length that matches the yellow tufts, the broom should be replaced.

Always check the main broom pattern when installing a new broom.
