Clearing a Clogged
Discharge Chute
Operating Tips
The auger blades can throw stones, toys, and
other foreign objects and cause serious personal
injury to the operator or to bystanders.
• Keep the area to be cleared free of all objects
that the auger blades could pick up and throw.
• Keep all children and pets away from the area
of operation.
Hand contact with the rotating auger blades
inside the discharge chute is the most common
cause of injury associated with snow throwers.
Never use your hand to clean out the discharge
chute.
To clear the chute:
• Do not operate snow thrower if weather condi-
tions impair visibility. Throwing snow during
a heavy, windy snowstorm can blind you and
be hazardous to the safe operation of the snow
thrower.
1. SHUT THE ENGINE OFF!
2. Wait 10 seconds to be sure the auger blades have
stopped rotating.
3. Always use a clearing tool at least 15 inches long, not
your hands (Figure 19).
•
•
The best time to remove snow is the early morning.
At this time the snow is usually dry and has not been
exposed to the direct sun and warming temperatures.
Slightly overlap each successive path to ensure all
snow will be removed.
•
•
Throw snow downwind whenever possible.
For extremely heavy snow, reduce the width of snow
removal by overlapping previous path and moving
slowly.
•
•
•
•
Keep engine clean and clear of snow during use. This
will help air flow and extend engine life.
After snow-throwing is completed, allow engine to run
for a few minutes to melt snow and ice off the engine.
Clean the entire snow thrower thoroughly after each
use and wipe dry so it is ready for next use.
Spraying off unit with a hose is NOT recommended.
Figure 19
Preventing Freeze-up after
Use
•
Let the engine run for a few minutes to prevent moving
parts from freezing. Stop the engine, wait for all mov-
ing parts to stop, and remove ice and snow from the
snowthrower.
•
•
Clean off any snow and ice from the base of the chute.
Rotate the discharge chute left and right to free it from
any ice buildup.
•
With the ignition key in the Off position, pull the recoil
starter handle several times or connect the electrical
cord to a power source and the snowthrower and push
theelectricstartbuttononcetopreventtherecoilstarter
and/or the electric starter from freezing up.
•
In snowy and cold conditions, some controls and mov-
ing parts may freeze. Do not use excessive force when
trying to operate frozen controls. If you have difficulty
operating any control or part, start the engine and let
it run for a few minutes.

ENGINE OIL
Storage
Drain oil (with engine warm) and replace with clean engine
oil. (See “Changing the Engine Oil” section of this manual).
Storing the Snowthrower
CYLINDER
1. Remove spark plug.
2. Pour one ounce (29 ml) of oil through spark plug hole
into cylinder.
Immediately prepare your snow thrower for storage at
the end of the season or if the unit will not be used for 30
days or more.
3. Pullrecoilstarterhandleslowlyafewtimestodistribute
oil.
WARNING: Never store the snow thrower with
gasoline in the tank inside a building where fumes
may reach an open flame, spark or pilot light as
on a furnace, water heater, clothes dryer or gas
appliance. Allow the engine to cool before storing
in any enclosure.
OTHER
•
•
•
Remove safety ignition key; store it in a safe place.
Do not store gasoline from one season to another.
Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline will cause problems.
•
•
If possible, store your snow thrower indoors and cover
it to protect it from dust and dirt.
Cover your snow thrower with a suitable protective
cover that does not retain moisture. Do not use plastic.
Plastic cannot breathe, which allows condensation to
form and will cause your snow thrower to rust.
SNOW THROWER
When snow thrower is to be stored for a period of time,
clean it thoroughly, remove all dirt, grease, leaves, etc.
Store in a clean, dry area.
1. Clean entire snow thrower after each use.
2. Inspect and replace belts, if necessary (See “Replace-
ing the Drive Belt” section of this manual).
IMPORTANT: Never cover snow thrower while engine/
exhaust area is still warm.
3. Besurethatallnuts,bolts,screws,andpinsaresecurely
fastened. Inspect moving parts for damage, breakage
and wear. Replace if necessary.
FUEL SYSTEM
IMPORTANT: It is important to prevent gum deposits from
forming in essential fuel system parts such as carburetor,
fuel hose, or tank during storage. Also, alcohol blended
fuels 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.
•
•
•
Empty the fuel tank by starting the engine and letting
