To Stop Engine

To stop engine, turn ignition key counter-clockwise. Disconnect the spark plug wire from the spark plug to prevent accidental starting while equipment is unattended.

To help prevent possible freeze-up of starter, proceed as follows:

Run engine for a few minutes before stopping to help dry off any moisture on the engine.

Electric Starter: Connect power cord to switch box on engine, then to 120 volt AC receptacle. With the engine running, push starter button and spin the starter for several seconds. The unusual sound made by spinning the starter will not harm engine or starter. Disconnect the power cord from receptacle first, and then from switch box.

Recoil Starter: With engine running, pull starter rope with a rapid, continuous full arm stroke three or four times. Pulling the starter rope will produce a loud clattering sound, which is not harmful to the engine or starter.

Wipe all snow and moisture from the carburetor cover in the area of the control levers. Also, move control levers back and forth several times. Leave throttle control lever in the STOP or OFF position. Leave choke control in the FULL choke position.

Remove ignition key and disconnect spark plug wire to prevent accidental starting.

Operating the Snow Thrower

The pitch of the discharge chute controls the angle at which the snow is thrown.

Loosen the wing knob found on the left side of the discharge chute and pivot the upper chute upward or downward to the desired pitch. Retighten the wing knob before operating the snow thrower.

Position the discharge chute opening by using the Chute Handle to throw the snow in the desired direction. See Figure 5.

Operating Tips

Discharge snow downwind whenever possible. Slightly overlap each previously cleared path.

Lifting up on the handle will allow the rubber on the augers to propel the snow thrower forward. Pushing downward on the handle will raise the augers off the ground and stop forward motion.

NOTE: Excessive upward pressure on the handle will result in premature wear on the rubber auger blades which would not be covered by warranty.

Run the engine for a few minutes before stopping to help dry any moisture on the engine.

Clean the snow thrower thoroughly after each use.

WARNING: Muffler, engine and surrounding areas become hot and can cause a burn. Do not touch.

SECTION 5: MAKING ADJUSTMENTS

WARNING: NEVER attempt to make any adjustments while the engine is running, except where specified in the operator’s manual.

NOTE: On new units or units with a new shave plate installed, the augers may be slightly off the ground.

Shave Plate

• To check the adjustment of the shave plate, place

 

 

the unit on a level surface. See Figure 6. The

 

 

wheels, shave plate and augers should all contact

 

 

level surface. Note that if the shave plate is

 

 

adjusted too high, snow may blow under the

Augers

 

housing. If the shave plate wears out excessively,

or the unit does not self-propel, the shave plate

 

 

may be too low and needs to be adjusted.
