Before Starting Engine

Engine Oil

The engine is shipped with oil in it. Check the oil level 
before first use. 
1.  Stop engine and wait several minutes before checking 

oil level. Remove oil fill cap and dipstick.

2.  Wipe dipstick clean, insert it into oil fill hole and 

tighten securely.

3.  With engine on level ground, oil must be to FULL mark 

on dipstick.  See Figure 8.  If oil level is low, add oil.

Adding Engine Oil

Be sure to use the grade of engine oil specified in engine 
manual. To add oil:
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.

IMPORTANT:  

For complete detailed engine information, see 

the separate engine owner’s manual included with this unit.

Gasoline

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 during fueling.

3.  Never fill the fuel tank completely. Fill the tank to 

no more than 1/2 inch below bottom of filler neck to 
provide space for expansion of fuel.

NOTE:

 

This unit may include a fuel plug, which is only 

used during assembly to keep dirt and debris out of fuel 
tank.  Discard the fuel plug before filling the fuel tank.
5.  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

Operation

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.

Keep your snow 

thrower away from 

any open flame or an 

electrical spark and 

do not smoke during 

fueling.

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 chute assembly 

has been properly 

installed and is 

secured.

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.

WARNING

and free from rust or other foreign particles. Make 
sure to wipe off any spilled fuel before starting the 
engine.

6.  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 

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 chute assembly has been properly 
installed and is secured.

For location of all the engine controls referred to in this 
section, see the engine owner’s manual.

Recoil Starter - Cold Start

1.  Make sure that auger and drive controls are 

released. Attach spark plug wire to spark plug.

2.  Turn fuel valve on, if so equipped.
3.  Move throttle control to FAST position. 
4.  Push key into the ignition slot so that it snaps into 

place. Do not turn key. 

5.  Rotate choke control to FULL choke position.
6.  Push primer button while covering the vent hole. 

Remove your finger from the primer between primes. 
Do not prime if temperature is above 50º F; prime 
two times between 50º F and 15º F; and prime four 
times below 15º F.

7.  Grasp starter handle and pull rope out slowly until engine 

reaches start of compression cycle (rope will pull 
slightly harder at this point). Let the rope rewind slowly.

8.  Pull rope with a rapid, continuous, full arm stroke. 

Keeping a firm grip on the starter handle, let the rope 
return to the starter slowly. Repeat until engine starts.

9.  As the engine warms up, rotate the choke knob slowly 

to OFF position. If the engine falters, return to FULL 
choke, then slowly move to OFF choke position. 

10. Allow the engine to warm up for a few minutes 

because the engine will not develop full power until it 
reaches operating temperature.

11. Operate the engine at full throttle (FAST) when 

throwing snow. 

Warm Start:

1.  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.
