SECTION 4:  OPERATING YOUR SNOW THROWER

Before Starting Engine

Engine Oil

The engine is shipped with oil in it. Check the oil level 
before first use. For subsequent fill-ups, use the grade 
of engine oil specified in engine manual.

1.

Remove the dipstick from the oil fill. Pour fresh oil 
slowly through the plug. Replace dipstick. 

2.

Check and make sure that the level of oil is up to 
the FULL mark on the dipstick.

Gasoline

Never fill the fuel tank completely. Fill the tank to 
within 1/4"-1/2" from the top to provide space for 
expansion of fuel.

IMPORTANT: 

Your snow thrower is equipped with a 

plastic fuel plug for shipping purposes. Please discard it 
before filling up gasoline for the first time.

Always use clean, fresh, unleaded grade 
automotive gasoline. Fill the fuel tank outdoors and 
use a funnel or spout to prevent spilling. Make sure 
that the container from which you pour the gasoline  
is clean and free from rust or other foreign particles. 
Make sure to wipe off any spilled fuel before 
starting the engine.

At the end of the job, empty the fuel tank if the snow 
thrower is not going to be used for 30 days or 
longer. Store gasoline in a clean container and 
keep the cap in place on the container.

CAUTION: Never use engine or carburetor cleaner 
products in the fuel tank.

To Start Engine 

For location of all the engine controls referred to in this 
section, see Figure 5.

Recoil Starter

Make sure that the auger control bail and the drive 
control bail are released.

Move throttle control to FAST position. 

Push key into the ignition slot so that it snaps into 
place. Do not turn key. Remove plastic bag and 
keep the second key in a safe place.

Rotate choke control to FULL choke position.

Push the primer button while covering the vent hole. 
Remove your finger from the primer between primes. 
Do not prime if temperature is above  50

o

 F; prime 

two times between 50

o

 F and 15

o

 F; and prime four 

times below 15

o

 F.

Pull the starter handle rapidly. Do not allow the 
handle to snap back, but allow it to rewind slowly 
while keeping a firm hold on the starter handle.

As the engine warms up and begins to operate 
evenly, rotate the choke knob slowly to OFF 
position. If the engine falters, return to FULL choke, 
then slowly move to OFF choke position. 

Allow the engine to warm up for a few minutes 
because the engine will not develop full power until 
it reaches operating temperature.

Operate the engine at full throttle (FAST) when 
throwing snow. 

NOTE: If the starter motor runs but the engine does not
turn over, the starter gear may have frozen. Place the
snow thrower in a warmer part of the garage or storage
shade till the gear is free of the accumulated ice. 

Warm Start:

If restarting an engine after a temporary shut- 
down, rotate choke to OFF instead of FULL and do 
not prime. Pull starter handle as instructed before.

Electric Starter 

(if equipped)

Some models of the snow thrower may be equipped 
with an optional 120 volt A.C. electric starter. This 
electric starter, with a three-wire power cord and plug, 
is designed to operate on 120 volt AC household current. 
Follow the steps below to use the electric starter.

Cold Start:

Determine whether your house wiring is a three-
wire grounded system. Ask a licensed electrician if 
you are not certain.

WARNING: 

Gasoline is flammable and 

caution must be used when handling or storing 
it. Do not fill fuel tank while the snow thrower is 
running, when it is hot or when it is in an 
enclosed area.

WARNING: 

Keep your snow thrower away 

from any open flame or an electrical spark and 
do not smoke while filling the fuel tank.

WARNING: 

Be sure no one other than the 

operator  is standing near the snow thrower 
while starting or operating. Do not operate this 
snow thrower unless the discharge chute 
assembly has been properly installed and is 
secured.

WARNING: 

The electric starter must be 

properly grounded at all times to avoid the 
possibility of electric shock to the operator. If 
your house wiring system is not a three-wire 
grounded system, do not use this electric starter 
under any conditions.
