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 13 - 16).
Apply 5W-50 synthetic motor oil to the friction disc hex
shaft (see Figure 13).
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.
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.
LUBRICATION
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.
CAUTION
In order to keep the free-hand controls disengaging
properly when released, it is important to oil the free-
hand controls every 10 hours.
