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.
•  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 en-

gine 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.

TO REMOVE WHEELS (See Fig. 22)

•  Remove the klik pin and remove wheel from axle.

IMPORTANT:

 When installing wheel, be sure to use the in-

nermost hole in axle and the wheel hub hole.  To dis en gage 

drive system from the wheels (for pushing or trans port ing 

the snow thrower), remove klik pin from wheel hub and 

insert pin into the outermost hole in axle only.

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.

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 centre.

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 centre, 

which has proper equipment and experience to make any 

necessary ad just ments.
