Regular Maintenance

There are two grease fittings on the auger shaft (Figure
15). 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 14 - 16). 

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.

See lubrication notes at bottom of page.

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.
