WHEEL GEAR AND PAWL SERVICE
CAUTION: Before storing the sweeper, always empty the hopper bag to avoid spontaneous combustion.
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.
SERVICE AND ADJUSTMENTSBRUSH REPLACEMENT
NOTE: Brush replacement should be done one brush at a time.
1.Remove the hopper bag from the sweeper.
2.(Figure 27) 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.
3.(Figure 27) Slide the brush out of the retainers, noting on which side of the brush the bristles overlap.
4.(Figure 27) Install new brush, making sure the bristles overlap on the same side of the brush as before.
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 only one wheel from the sweeper.
2.Remove the retaining rings and washers which hold the ratchet gear onto the brush shaft.
3.(Figure 28) 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.)
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 ratchet gear back onto the shaft.
6.Lightly grease the axle and the gear teeth on the wheel, 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 ratchet gear. Disassemble to clean and lubricate the drive pin and the ratchet gear.
7.Remove the second wheel and repeat the procedure.
