MAINTENANCE
Controls and Linkage
All bushings, spindle shafts, and tie rod ends should be coated with a
light coat of oil or grease. Throttle and brake controls and cables
should be lubricated with LBS1, WD-40, etc. Force a small amount of
lubricant down the cable.
Bearings
To prevent corrosion which will destroy the bearings, always grease
drive shaft clutch side bearings with a high quality bearing grease.
Electrical Connections
Separate electrical connector blocks and clean corrosive build up from
connectors. Lubricate or pack connector blocks with Nyogelt grease
(PN 2871329) and re-connect. Replace worn or frayed electrical wire
and connectors. Be sure wiring harness is properly secured away from
sharp edges, steering linkage, moving parts, and hot exhaust.
Front Suspension
To minimize fatigue on the front shocks and springs during extended
storage, it is recommended that the front end of the machine be safely
blocked off the ground to remove tension from the shocks and springs.
