Maintenance
LUBRICATION
IMPORTANT NOTE
It is very important that grease fittings on the auger shaft are lubricated regularly. If auger rusts to shaft, damage to worm gear may occur if shear pins do not break.
To prevent wheels rusting to axles, it is also necessary to remove the wheels and grease the axles regularly.
Remove wheels and grease axles once each year.
There are two grease fittings on the auger shaft. Wipe the fittings clean and apply grease, using a grease gun. Also apply grease on other points indicated.
Apply medium weight (10W) oil to points shown (See Figures 15 - 18).
Apply
Generally, all moving metal parts should be oiled where contact is made with other parts. Keep oil and grease off belts, pulley grooves, drive disc, and friction disc.
LUBRICATION NOTES:
Grease locations indicated by grease gun symbol. Use grease fittings when present. Disassemble parts to apply grease to moving parts when grease fittings are not installed.
Oil locations indicated by oil can symbol. Do not allow oil to drip onto traction drive or friction disc.
