Skid Shoe Height Adjustment
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.

per or lower sides of the stand support. Adjust
