Lubrication
Note: The drive pulley end of auger shaft is supported
by a sealed ball bearing and requires no lubrication.
The ball bearing on other end of auger shaft is also
sealed, and will not require lubrication.
Lightly Oil
• A few drops of oil should be placed on
wheel hubs occasionally to keep wheels
turning freely.
• Apply oil to pivot points of auger control
periodically, wiping off any excess oil.
• A couple of drops of light machine oil applied to
upper end of auger control cable will assure free
movement of cable through outside casing. Wipe
off any excess oil (Figure 5).
• Remove belt cover and lightly apply oil to the pivot
point for idler pulley arm. BE CAREFUL NOT TO
GET OIL ON BELT OR PULLEYS.
Grease
• At the beginning of each snow throwing sea-
son, remove discharge chute, clean, and
generously lubricate steel flange at back of
rotating ring with light grease. Rotate ring
with crank to distribute grease (Figure 8).
Engine Lubrication
The two cycle engine used in this snow thrower is lubri-
cated by the fuel and oil mixture. Observe recommend-
ed fuel to oil mixture ratio shown on page 5.
