Lubrication
• Drive Mechanism: Once a season or after every
25 hours of operation, remove rear frame cover and
lubricate any chains, sprockets, gears, bearings,
and shafts with engine oil or lubricant spray.
IMPORTANT: Avoid oil spillage on rubber friction
wheel and aluminum drive plate.
• Hex Gear Shaft: Once a season, lubricate the hex
shaft with a penetrating oil, but not grease,
• Gear Case: The gear case is lubricated with
grease at the factory and does not require regular
lubrication. However, if disassembled for any
reason, lubricate with 2 ounces of Shell Alvania
TM
grease (part # 737-0168). Before reassembling,
remove old sealant and apply new sealant.
IMPORTANT: Do not overfill the gear case, since
damage to the seals could result.
• Wheels: Once a season, remove the bolt from
each wheel and take the wheel off the axle. Apply a
multipurpose automotive grease on the shaft
before putting back the wheels.
• Shift Rod: Use a grease or light oil to lubricate the
rotating parts of the shift rod after 25 hours of
operation.
• Pivot Points: All pivoting points on the snow
thrower should be lubricated with a light oil once a
season.
