OPERATION

BEFORE STARTING THE ENGINE

1.Before you service or start the engine, familiarize yourself with the snow thrower. Be sure you understand the func- tion and location of all controls.

2.Be sure that all fasteners are tight.

3.Before starting the engine, make sure all controls operate correctly.

HOW TO STOP THE ENGINE

To stop the engine, move the ignition key to the stop position.

HOW TO START THE ENGINE

The following starting instructions include directions for both Recoil Start and Electric Start engines. For models that are Recoil Start only, disregard the Electric Start information.

Electric Start models are equipped with a 120 volt AC electric starter and also a recoil starter. Before starting the engine, make certain that you have read the following information.

The starter is designed to operate on 120 volt A.C. household current. Carefully follow all instruc- tions in the “How To Start The Engine” section.

To connect a 120 volt A.C. power cord, always connect the power cord to the switch box on the engine first. Then, plug the other end into the receptacle. When dis- connecting the power cord, always unplug the end from the receptacle first.

HOW TO START A COLD ENGINE

1.Fill the fuel tank with a fresh, clean fuel mixture. See “How To Mix The Fuel Mixture”.

2.Move the choke control to FULL position.

3.Make sure the auger drive lever is in the disengaged (re- leased) position.

4.Insert the ignition key and turn to the ON position.

5.(Electric Start) Connect the power cord to the switch box located on the engine.

6.(Electric Start) Plug the other end of the power cord into a 120 VOLT, A.C. receptacle. (See the WARNING in this section).

7.Push the primer button while covering the vent hole as follows: Remove finger from primer button between primes.

SDo not prime if temperature is above 50° F (10° C).

SPush twice if temperature is 50° F (10° C) to 15°F (−10° C).

SPush four times if temperature is below 15° F (−10° C).

SPush five time if temperature is below 0° F (−18° C).

8.(Electric Start) Push on the electric start button until the engine starts. Do not crank for more than 10 seconds at a time. The electric starter is thermally protected. If the electric starter overheates, it will automatically stop and can only be restarted when it has cooled to a safe temper- ature. A wait of about 5 to 10 minutes is required to allow the electric starter to cool and the thermal protection to re- set..

9.(Recoil Start) Rapidly pull the recoil starter handle. Do not allow the recoil starter handle to snap back. Slowly return the recoil starter handle.

10.If the engine does not start in 5 or 6 tries, See the “Trouble Shooting Chart” Instructions.

11.(Electric Start) When the engine starts, release the elec- tric start button.

12.(Electric Start) First disconnect the power cord from the receptacle. Then, disconnect the power cord from the

switch box.

13.As the engine warms up, move the choke control to 1/2 choke position. When the engine runs smoothly, move the choke control to the off position.

NOTE: Allow the engine to warm up for several minutes before blowing snow in temperatures below 05F.

WARM START

If restarting a warm engine after a short shutdown, leave choke at “OFF” and do not push the primer button. If the engine fails to start, follow the Cold Start instructions.

WARNING: Never run engine indoors or in en- closed, poorly ventilated areas. Engine exhaust contains CARBON MONOXIDE, AN ODORLESS AND DEADLY GAS. Keep hands, feet, hair and loose

clothing away from any moving parts on engine and snow thrower.

The temperature of muffler and nearby areas may ex- ceed 1505F. Avoid these areas.

DO NOT allow children or young teenagers to operate or be near snow thrower while it is operating.
