Lubrication
CAUTION
Before servicing or making adjustments
to the machine, stop engine and remove
the key from the ignition switch.
The rear wheel has grease fittings that must be lubri-
cated regularly with No. 2 general purpose lithium base
grease. If the machine is operated under normal condi-
tions, lubricate all bearings and bushings after every 50
hours of operation. Lubricate fittings immediately after
every washing, regardless of the interval listed.
The rear wheel bearings and bushings that must be lu-
bricated are: rear wheel hub, castor fork bearing, and
ball joints.
1. Wipe grease fittings clean so foreign matter cannot
be forced into the bearing or bushing.
2. Pump grease into the bearing or bushing.
3. Wipe up excess grease.
