MAIN BROOM

To prevent the main broom from setting in one direction and to provide maximum life of the broom. It is recom- mended that the broom be turned end for end periodically.

TO CHECK 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. Allow the machine to sweep in one spot for a short period of time.

2.Before moving machine, move main broom lever to the “UP” position and move the sweeper forward until you can 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.

The recommended 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”.

TO ADJUST THE MAIN BROOM SWEEP 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. Locate the Main Broom Height Adjustment which is located at the rear bottom of machine. Turn the adjustment screw as described below.

-Turn the adjustment bolt counterclockwise to INCREASE the sweep pattern width. -Turn the adjustment screw clockwise to DECREASE the sweep pattern width..

WARNING

To prevent unexpected movement always park on a hard, level surface and turn key switch off before working on

the machine.
