CLEAN/LUBRICATE WHEEL GEARS
Every two years remove the wheels and clean the
gears found inside the wheel housing. After clean-
ing, lubricate with an even coat of light grease. To
remove the wheel, pop off the hub cap using a
screwdriver, remove the lock nut and flat washer
and then the wheel. See figure 24.
CLEAN SWEEPER
1. Clean sweeper housing with a soft brush or cloth.
2. Clean debris from hopper bag with a brush or
broom.
3. Remove any material which has wrapped around
brushes or ends of brush shaft.

RATCHET GEAR/DRIVE PIN REPLACEMENT
IMPORTANT: Do not
remove both wheels at the
same time to avoid mixing of parts. (The R.H. and
L.H. ratchet 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 ratchet 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 25.
4. To reassemble, insert the drive pin through the
hole near the end of the brush shaft. Make sure the
pin slides back and forth easily in the shaft.
5. Lightly grease the shaft and fill the ratchet 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 reverse rota-
tion of the wheel, either the RH and LH ratchet
gears have been switched or the drive pin is jam-
ming in the ratchet gear. Clean and lubricate the
drive pin and the ratchet gear to prevent jamming.
1. Clean the sweeper and hopper bag thoroughly to
help prevent rust and mildew.
2. To collapse the hopper bag for storage, remove the
two hopper support rods from the rear of the
hopper.
3. Store in a dry area.
CAUTION: Before storing
the sweeper,
always empty the hopper bag to avoid
spontaneous combustion.
