Sweep System, Main 383Service Manual – CS7000
Note: If the width of the main broom sweep pattern is not consistent along the entire length of the
main broom, you may need to adjust the main broom tilt. Refer to the To Adjust the Main
Broom Tilt section below.
To Adjust the Main Broom Tilt
1. Loosen the two 1/4”-20 Nyloc
®
Nuts
holding the Bearing on
which the Broom Support
Weldment
pivots on the right
side. Note that the 1/4”-20
Nyloc
®
Nuts and Bearing are
accessed from the inside of the
main broom compartment and
are located behind the 1/2”-13
Screw
just to the rear of the
Broom Arm Assembly. Also note
that the Bearing and mounting
screws ride in slotted holes in
the supporting weldment to
allow for up/down adjustment.
2. Move the Bearing and attached
Broom Support Weldment up
or down as necessary so the
width of the main broom
sweep pattern is consistent
along the entire length of the
main broom. Note that:
• Raising the right side of the
main broom will narrow the
sweep pattern on the right
side.
• Lowering the right side of
the main broom will widen
the sweep pattern on the
right side.
3. Tighten the two 1/4”-20 Nyloc
®
Nuts
.
4. Check the main broom sweep
pattern.
5. Readjust the main broom tilt
as necessary.
