How To Replace the Auger Shear Bolt
The augers are secured to the auger shaft with
special shear bolts. These shear bolts are de-
signed to break and protect the machine if an
object becomes lodged in the auger housing.
Do not use a harder belt as the protection pro-
vided by the shear bolt will be lost.
_k ARNING: For safety and to pro-
tect the machine, use only original
equipment shear belts.
To replace a broken shear belt, proceed as fol-
lows. Extra shear belts were provided in the as-
sembly parts bag.

the stop position. Disengage all controls.
2. Disconnect the spark plug wire. Make sure
all moving parts have stopped.

How To Prepare The Snow Thrower For
Storage
_k ARNING: Do not remove gasoline
while inside a building, near a fire,
or while you smoke. Gasoline
fumes can cause an explosion or a fire.
1. Drain the fuel tank.
2. Let the engine run until it is out of gasoline.
3. Drain the oil from the warm engine. Fill the
engine crankcase with new oil.
4. Remove the spark plug from the cylinder.
Pour one ounce of oil into the cylinder. Slow-
ly pull the recoil-start grip so that the oil will
protect the cylinder. Install a new spark plug
in the cylinder.
5. Tberoughly clean tbe snow thrower.
6. Lubricate all iubdcation points. See the Main-
tenance section.
7. Be sure that all nuts, bolts and screws are
securely fastened. Inspect all visible moving
parts for damage, breakage and wear. Re-
place ff necessary.
8. Cover the bare metal parts of the blower
housing, auger, and the impeller with spray
rust preventative lubricant.
9. Put the unit in a building that has good ven-
tilation.
10.If the machine must be stored outdoors,
block up the snow thrower to be sure the en-
tire machine is off the ground.
