which fasten itto the wheel housing.(It isnot necessary
to remove the dust cover ifyou are onlycleaningand
lubricatingthe chain and sprockets.)
• Remove the retainingringsand washers which holdthe

• To reassemble, insertthe drive pinthroughthe hole at
the end of the brush shaft. Make sure the pinslides
