Rotary Broom Brush Leveling

IMPORTANT: The proper level adjustment of the broom is essential for efficient operation and life of the bristles. The broom should regu- larly be adjusted to prevent uneven brush wear.

1.Extend the parking stands and raise the broom to the transport position (so that the bristles do not contact the ground).

2.Loosen the three bolts on the upper coupler of the pivot bracket.

3.Gently lower the broom head until the brush is parallel to ground level on both sides. Place a block of wood under each side of the brush to keep the brush in place.

4.Tighten the three bolts on the upper coupler, re- move the wood blocks, and lower the broom to the ground to make sure the brush is level.

This adjustment is required for lawn thatching or leaf raking operations. Height is adjusted to the nearest 1/4 in. (6 mm) by placing spacer sleeves on the up- per or lower sides of the stand support. Adjust height according to type of application. Refer to Lawn Thatching and Leaf Raking in Operating In-
