BRUSH REPLACEMENT

NOTE: Brush replacement should be done one brush at
a time.
1. Remove the hopper bag from the sweeper.
2. Loosen the hex bolts and lock nuts on two single
brush retainers which clamp one brush to the double
brush retainers. Do Not loosen or remove the bolts
which fasten the double brush retainers to the brush
shaft. See figure 21.
3. Slide the brush out of the retainers, noting on which
side of the brush the bristles overlap. See figure 21.
4. Install new brush, making sure the bristles overlap on
the same side of the brush as before. See figure 21.

TROUBLESHOOTING

1. Brushes set too low.
2. Brushes are jammed
3. Wheels are jammed.
WHEEL GEAR AND PAWL SERVICE
IMPORTANT: Do not remove both wheels at the same
time to avoid mixing of parts. (The R.H. and L.H. pinion
gears are not interchangeable.) Make notes on the position
of washers and snap rings during disassembly.
1. Remove one wheel from the sweeper.
2. Remove the retaining rings and washers which hold
the pinion gear onto the brush shaft.
3. Remove the gear by sliding it off the brush shaft. (Look
for the drive pin, which may fall out of the brush shaft
when the ratchet gear is removed.) See figure 22.
4. To reassemble, insert the drive pin into the hole in the
brush shaft. Make sure the pin slides back and forth
easily in the shaft.
5. Lightly grease the shaft and fill the pinion gear with
grease. Assemble the gear back onto the shaft.
6. Lightly grease the axle and the wheel's gear teeth
and then reassemble the wheel. The brushes should
rotate only during forward rotation of the wheel. If
the brushes are driven (rotated) by both forward and
reverse rotation of the wheel, the drive pin is jamming
in the pinion gear. Disassemble to clean and lubricate
the drive pin and the pinion gear.
