conveyor. If a side broom is tilted at too large an
angle, debris will trail or be scattered, and the
broom will wear too fast. If the main broom is not
kept parallel to the swept surface, the broom will
wear into a coned (tapered) shape and will give
poor sweeping performance.
If a broom’s bristles have worn to less than half of
their original length, the broom will produce a
small pattern and poor sweeping performance.
To check the broom patterns:
1. Make sure that the tires are inflated to the
correct pressure.
2. Park the sweeper on a level, paved surface.
3. Using the MB / Conv Height switch (50, Figure
O-1) and the Broom Height switch(es) (26
and/or 46), lower the main broom and side
broom(s).
4. As necessary, use the Broom Rotate switches
(22, 27, 45) to start rotation of the brooms.
5. Using the Engine Throttle Control knob (53,
Figure O-2), increase engine speed to about
2500 rpm.
6. Sweep in one spot for about 15 seconds.
7. Stop broom rotation by using the Broom
Rotate switches (22, 27, and/or 45, Figure O-1).
8. Use the Broom Height switch(es) (26 and/or
46) to raise the side brooms.
9. If the sweeper has standard main broom sus-
pension, use the MB / Conv Height switch (50)
to raise the main broom.
If the sweeper has hydraulic main broom sus-
pension, use the CONV LOWER / MB/CONV
UP switch (47) to raise the main broom.
10. Drive forward far enough to reveal the pat-
terns left on the pavement by the brooms.
11. Check that the side broom patterns are cres-
cent-shaped and approximately 4 inches wide
