How To Replace the Auger Shear Bolt
The augers are secured to the auger shaft with
special shear bolts. These shear bolts are
designed to break and protect the machine if an
object becomes lodged in the auger housing. Do
not use a harder bolt as the protection provided
by the shear bolt will be lost.

WARNING: For safety and to
protect the machine, use only
original equipment shear bolts.
To replace a broken shear bolt, proceed as
follows. Extra shear bolts were provided in the
assembly parts bag.
1. (Figure 1) Move the throttle control (13) to
the stop position. Disengage all controls.
2. Disconnect the spark plug wire. Make sure
all moving parts have stopped.
3. (Figure 18) Lubricate the auger shaft Zerk
fitting (1), if equipped, with a grease gun.

How To Prepare The Snow Thrower For
Storage
WARNING: Do not remove gasoline
while inside a building, near a fire,
or while you smoke. Gasoline
fumes can cause an explosion or a fire.
If the snow thrower is to be stored for an
extended period, refer to the engine
manufacturer's operating manual (included with
some models) for important maintenance or
storage details.
1. Drain the fuel tank.
2. Let the engine run until it is out of gasoline.
3. Never store the snow thrower with fuel in the
tank inside a building where ignition sources
are present such as hot water and space
heaters, clothes dryers, and the like. Allow the
engine (motor) to cool before storing in any
enclosure.
4. Drain the oil from the warm engine. Fill the
engine crankcase with new oil.
5. Remove the spark plug and pour about 15 ml
(1/2 oz) of engine oil into the cylinder.
Replace the spark plug and crank slowly to
distribute the oil.

6. Thoroughly clean the snow thrower.
7. Lubricate all lubrication points. See the
Maintenance section.
8. Be sure that all nuts, bolts and screws are
securely fastened. Inspect all visible moving
parts for damage, breakage and wear.
Replace if necessary.
9. Cover the bare metal parts of the blower
housing, auger, and the impeller with spray
rust preventative lubricant.
10. Put the unit in a building that has good
ventilation. Store in a clean and dry area, but
NOT near a stove, furnace or water heater
which uses a pilot light or any device that can
create a spark.
11. If the machine must be stored outdoors,
block up the snow thrower to be sure the
entire machine is off the ground.
12. Cover the snow thrower with a suitable
protective cover that does not retain
moisture. Do not use plastic.
