SERVICE AND ADJUSTMENTS
STORAGE
Immediately prepare your unit for storage at the end of the
season or if the unit will not be used for 30 days or more.
WARNING: Never store the snow
thrower with gaso line in the tank in side
a build ing where fumes may reach an
open flame, spark or pilot light as on a
fur nace, water heater, clothes dryer or
gas ap pli ance. Allow the engine to cool
be fore storing in any enclosure.
SNOW THROWER
When snow thrower is to be stored for a period of time,
clean it thor oughly, re move all dirt, grease, leaves, etc.
Store in a clean, dry area.
1. Clean entire snow thrower (See “CLEANING” in the
Main te nance section of this manual).
2. Inspect and replace belts, if necessary (See “TO RE-
PLACE BELTS” in the Service and Adjustments sec tion
of this manual).
3. Lubricate as shown in the Main te nance sec tion of this
man u al.
4. Be sure that all nuts, bolts, screws, and pins are securely
fas tened. Inspect moving parts for damage, breakage
and wear. Replace if nec es sary.
5. Touch up all rusted or chipped paint surfaces; sand
lightly before painting.
ENGINE
See engine manual.
FUEL SYS TEM
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 (called gasohol or 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.
ENGINE
See engine manual.
CARBURETOR
Your carburetor is not adjustable. Engine performance
should not be affected at altitudes up to 7,000 feet (2,134
meters). If your engine does not operate properly due to
suspected carburetor problems, take your snow thrower
to a qualified service center.
• Empty the fuel tank by starting the engine and letting
it run until the fuel lines and car bu re tor are empty.
• Never use engine or carburetor cleaner prod ucts in
the fuel tank or permanent damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable alternative in min-
i miz ing the formation of fuel gum deposits during stor age.
Add stabilizer to gasoline in fuel tank or storage container.
Always follow the mix ratio found on stabilizer container.
Run engine at least 10 min utes after adding stabilizer to
allow the stabilizer to reach the carburetor. Do not drain the
gas tank and carburetor if using fuel stabilizer.
ENGINE OIL
Drain oil (with engine warm) and replace with clean engine
oil. (See “ENGINE” in the Maintenance section of this
man ual).
CYLINDER
1. Remove spark plug.
2. Pour one ounce (29 ml) of oil through spark plug hole
into cylinder.
3. Pull recoil starter handle slowly a few times to dis trib ute
oil.
4. Replace with new spark plug.
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 pro tec tive
cover that does not retain moisture. Do not use plastic.
Plastic cannot breathe, which allows con den sa tion to
form and will cause your snow thrower to rust.
IMPORTANT: Never cover snow thrower while engine/ex-
haust area is still warm.
ENGINE SPEED
Never tamper with the engine governor, which is factory set
for proper engine speed. Overspeeding the engine above
the factory high speed setting can be dangerous and will
void the warranty. If you think the engine-governed high
speed needs adjusting, contact a qualified service center,
which has proper equipment and experience to make any
necessary ad just ments.
TO REMOVE WHEELS (See Fig. 22)
• Remove the klik pin and remove wheel from axle.
IMPORTANT: When installing wheel, be sure to use the
axle hole closest to the end of the shaft – do not use the
hole in the wheel hub (if equipped). Inner hole in axle and
hole in wheel hub are not used for your model snow thrower.

NOTE: To seal punctures or prevent flat tires due to slow
leaks, tire sealant may be purchased from your local parts
dealer. Tire sealant also prevents tire dry rot and cor ro sion.
