Drive Wheels
The wheels may be adjusted for two different methods
of operation. The adjustment is made by placing the
click pins in one of two different holes on the right side
of the unit. See Figure 10.
Figure 10
One Wheel Driving: Insert the click pin only through
the outside hole of the axle (NOT the rim) on the right
side of the snow thrower. This position gives power
drive to the left wheel only, making the unit easier to
maneuver.
Both Wheels Driving: Insert the click pin through the
hole in the hub of the rim and the INSIDE hole on the
snow thrower’s right axle. This position is good for
heavy snow as there is power drive in both wheels.
IMPORTANT:
NEVER operate the snow thrower with the
click pin inserted through both the RIM and the
OUTSIDE HOLE in the axle. Doing so can result in
serious damage to the drive system.
Skid Shoe Adjustment
The space between the shave plate and the ground can
be adjusted by raising or lowering the skid shoes. Refer
to Skid Shoe Adjustment in the Assembly Section.
Auger Control Adjustment
Refer to the information found under Final
Adjustments in the Assembly Section to adjust the
auger control.
SECTION 6: MAINTAINING YOUR SNOW THROWER
WARNING: Before lubricating, repairing,
or inspecting, disengage all clutch levers
and stop engine. Wait until all moving
parts have come to a complete stop.
Disconnect spark plug wire and ground it
against the engine to prevent unintended
starting.
Lubrication
Engine
Refer to the separate engine manual packed with your
unit for all engine lubrication instructions.
IMPORTANT:
When following instructions in separate
engine manual for draining oil, be sure to protect frame
to avoid oil dripping onto transmission parts.
Gear Shaft
Lubricate the gear shaft with 6-n-1 grease at least once
a season or after every 25 hours of operation (available
at automotive stores, or order part number 737-0170).
Refer to Figure 8.
IMPORTANT:
Keep all grease and oil off of the rubber
friction wheel and aluminum drive plate.
Drive and Shifting Mechanism
Lubricate at least once a season or after every 25 hours
of operation. Remove the rear cover, lubricate any
chains, sprockets, gears, bearings, shafts, and shifting
mechanism at least once a season. Use engine oil or a
spray lubricant. Avoid getting oil on the friction
wheel rubber and aluminum drive plate. Refer to
Figure 8.
There is a grease fitting on the top of the axle shaft
which drives the rear track drive wheels on both sides
of the unit. Grease these fittings every 25 hours or once
a season.
Electric Chute-Rotation Motor
The gear on the electric chute-rotation motor and the
base of the discharge chute itself should be lubed with
multi-purpose automotive grease once a season.
See Figure 11.
