Maintenance
LUBRICATION
General: 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.
Auger Shaft: There are two grease fittings on the auger
shaft (Figure 16). 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 in
Figures 15-17.
Drive System: Keep grease and oil off the friction disk
(see Figure 15) and drive disk. Clean and lubricate the
hex shaft with 5W-50 synthetic motor oil.
CHECK / LUBRICATE FREE-HAND
LINKAGE
Check the function of the Free-Hand controls: the con-
trols should function as described in the CONTROLS
section. It is critical for the safe operation of the unit
that the controls disengage when released.
If the controls do not function properly, lubricate them. If
lubrication does not rectify the problem, see your dealer.
Under no circumstances should the unit be used if the
controls are not functioning properly.

NOTICE
It is very important to lubricate the grease fittings on
the auger shaft regularly. If the augers rust to the
shaft, damage to the gear box may occure if the
shear pins do not break.
To prevent the wheels from rusting to the axles it is
necessary to remove the wheels and grease the axle
shafts yearly.
