SECTION 6: MAINTAINING YOUR SNOW THROWER
WARNING: Before lubricating, repairing, or
inspecting, disengage all controls and stop
engine. Wait until all moving parts have come
to a complete stop. Disconnect the spark plug
wire and ground it against the engine to
prevent unintended starting. Always wear
safety glasses during operation or while
performing any adjustments or repairs.
General Recommendations
• Always observe safety rules when performing any
maintenance.
• The warranty on this snow thrower does not cover
items that have been subjected to operator abuse
or negligence.
• Some adjustments will have to be made
periodically to maintain your unit properly.
• All adjustments in the service and adjustments
sections of this manual should be checked at least
once each season.
• Follow the maintenance schedule given below.
• Periodically check all fasteners and hardware to
make sure these are tight.
Check V-Belts
Follow the instructions below to check the condition of
the drive belts every 50 hours of operation.
• Remove the plastic belt cover on the front of the
engine by removing the three self-tapping screws.
• Visually inspect for frayed, cracked, or excessively
worn out belts.
• Replace belts as necessary as outlined in SERVICING
YOUR SNOW THROWER.
Lubrication
Auger Shaft
• At least once a season, remove the shear bolts
from the auger shaft and spray lubricant inside the
shaft. See Figure 14.
• Grease fittings can be found at either end of the
auger shaft. Lubricate with a grease gun once a
season. See Figure 14.
Gear Case
The auger gear case is equipped with a grease fitting.
Lubricate with Shell Alvania lead-free grease once a
season (order part number 737-0168). See Figure 14.
IMPORTANT:
To relieve pressure, remove the vent plug
before lubricating the gear case. See Figure 14. Failure
to do so could result in damage to the gear case seals.
Figure 14
Chute Assembly
The base of the chute assembly and the spiral on the
chute directional control should be lubricated at least
every 25 hours of use. Apply the lubricant under the
base of the chute assembly and where the spiral
contacts the chute assembly. See Figure 15.

Drive and Shifting Mechanism
At least once a season or after every 25 hours of
operation, remove rear cover. Lubricate any chains,
sprockets, gears, bearings, shafts, and the shifting
mechanism at least once a season. Use engine oil or a
spray lubricant. Avoid getting oil on friction wheel and
aluminum drive plate. Refer to Figure 11.
Gear Shaft
Lubricate the gear shaft with 6-in-1 grease (part
number 737-0170) at least once a season, or after
