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.
S Do not prime if temperature is above 50° F (10° C).
S Push twice if temperature is 50° F (10° C) to
15°F (−10° C).
S Push four times if temperature is below 15° F (−10° C).
S Push 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.

ceed 1505F. Avoid these areas.
DO NOT allow children or young teenagers to operate
or be near snow thrower while it is operating.
