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 bolt as the protection pro- vided by the shear bolt will be lost.

WARNING: For safety and to pro- tect the machine, use only original equipment shear bolts.

To replace a broken shear bolt, proceed as fol- lows. Extra shear bolts were provided in the as- sembly parts bag.

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.

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.Thoroughly clean the snow thrower.

6.Lubricate all lubrication 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 if 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.

11.Cover the snow thrower with a suitable pro- tective cover that does not retain moisture. Do not use plastic.
