Maintenance - Craftsman C459-52924 Operator's Manual

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.
engine
Refer to the separate engine manual packed with your unit for all
engine maintenance.
Lubrication
engine
Refer to the separate engine manual packed with your unit for all
engine lubrication instructions.
NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve start-
ing in cold weather, these multi-viscosity oils also result in higher oil
consumption when used above 32ºF (0ºC). Check your snow thrower's
engine oil level more frequently to avoid possible engine damage from
running low on oil.
gear Shaft
The gear (hex) shaft should be lubricated at least once a season or
after every 25 hours of operation.
WARNING: Run the engine completely dry of
gasoline before tipping snowthrower.
1. Carefully pivot the snow thrower up and forward so that it rests on
the auger housing.
2. Remove the lower frame cover by removing the screws which
secure it.
3. Apply a light coating of an all-weather multi-purpose oil to the hex
shaft. See Figure 14.
NOTE: Avoid getting oil on rubber friction wheel and aluminum drive
plate.
Wheels
At least once a season, remove both wheels. Clean and coat the axles
with a multipurpose automotive grease before reinstalling wheels.
Auger Shaft
At least once a season, remove the shear pins on auger shaft. Spray
lubricant inside shaft, around the spacers. Also lubricate the flange
bearings found at either end of the shaft. See Figure 15.
Augers
• The augers are secured to the spiral shaft with shear pins and cotter pins.
If the auger should strike a foreign object or ice jam, the snow thrower is
designed so that the pins may shear. Refer to Figure 15.
• If the augers will not turn, check to see if the pins have sheared.
One set of replacement shear pins has been provided with the
snow thrower. When replacing pins, spray an oil lubricant into shaft
before inserting new pins.
Shave Plate and Skid Shoes
The shave plate and skid shoes on the bottom of the snow thrower are
subject to wear. They should be checked periodically and replaced
when necessary.
