OPERATION
BEFORE STARTING THE ENGINE
WARNING: Experiences indicates that alcohol
blended fuels (called gasohol or those using
ethanol or methanol) can attract moisture
which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system
of an engine while in storage.
NOTE: To avoid engine problems, the fuel system
must be emptied before storage for 30 days or longer.
Start the engine and let it run until the fuel lines and
carburetor are empty. Use the carburetor bowl drain
to empty residual gasoline from the float chamber.
Use fresh fuel next season. See the Storage section in
this manual for additional information.
Never use engine or carburetor cleaner products in the
fuel tank or permanent damage can occur.
HOW TO MIX THE FUEL MIXTURE
The two cycle engine, used on this snow thrower, requires
a mixture of gasoline and oil for lubrication of the bearings
and other moving parts. The correct fuel mixture ratio is
50:1 (2.6 oz. oil per one gallon of gas - see the Fuel Mixture Chart). Gasoline and oil must be pre-mixed in a clean
gasoline container. Always use fresh, clean, unleaded gasoline.

OPERATION
HOW TO REMOVE SNOW FROM THE AUGER
HOUSING
WARNING: Do not attempt to remove snow or
debris that may become lodged in auger
housing without taking the following precau-
tions.
1. Release the auger drive lever.
2. Remove the ignition key.
3. Disconnect the spark plug wire.
4. Do not place your hands in the auger housing or the dis-
charge chute. Use a pry bar to remove any snow or debris.
SNOW THROWING TIPS
1. When the handle is raised, the auger blades will engage
the ground and the snow thrower will move forward. When
the auger drive lever is released, the auger blades will
stop. If the blades do not stop, see “How To Adjust The Auger Control Cable” in the Service And Adjustment section.
2. Most efficient snow throwing is accomplished when the
snow is removed immediately after if falls.
3. For complete snow removal, slightly overlap each previous path.
4. Whenever possible, discharge the snow down wind.
5. The distance the snow will be discharged can be adjusted
by moving the discharge chute deflector. Raise the deflector for more distance or lower the deflector for less distance.
6. In windy conditions, lower the chute deflector to direct the
discharged snow close to the ground where it is less likely
to blow into unwanted areas.
7. For safety and to prevent damage to the snow thrower,
keep the area to be cleared free of stones, toys and other
foreign objects.
8. Do not use the auger propelling feature when clearing
gravel or crushed rock driveways. Move the handle down
to slightly raise the auger.
9. The forward speed of the snow thrower is dependent on
the depth and weight of the snow. Experience will establish the most effective method of using the snow thrower
under different conditions.
10. After each snow throwing job, allow the engine to run for
a few minutes. The snow and accumulated ice will melt off
the engine.
11. Clean the snow thrower after each use.
12. Remove ice, snow and debris from the entire snow thrower. Flush with water to remove all salt or other chemicals.
Wipe snow thrower dry.
DRY AND AVERAGE SNOW
1. Snow up to eight inches deep can be removed rapidly and
easily by walking at a moderate rate. For snow or drifts of
a greater depth,slow your pace to allow the discharge
chute to dispose of the snow as rapidly as the auger receives the snow.
2. Plan to have the snow discharged in the direction the wind
is blowing.
WET PACKED SNOW
Move slowly into wet, packed snow. If the wet, packed snow
causes the auger to slow down or the discharge chute begins
to clog, back off and begin a series of short back and forth
jabs into the snow. These short back and forth jabs, four to six
inches, will “belch” the snow from the chute.
SNOW BANKS AND DRIFTS
In snow of greater depth than the unit, use the same “jabbing”
technique described above. Turn the discharge chute away
from the snow bank. More time will be required to remove
snow of this type than level snow.
