1: Loosen the four hex nuts (Two on each said)and carriage
bolts. Move skid shoes to desired position
2: Make certain the entire bottom surface of skid shoe is
against the ground to avoid uneven wear on the skid shoes
3: Retighten nuts and bolts securely.
Chute Bracket Adjustment
If the spiral at the bottom of the chute directional control is not fully
engagina with the chute assembly,the chute bracket can be adjusted. To do so:

Checking Spark Plug
Check spark plug yearly or every 100 operating hours
1. Clean area around spark plug.
2. Remove and inspect spark plug
3. Replace spark plug if porcelain is cracked
or if electrodes are pitted, burned or fouled with deposits
4. Check electrode gap with a feeler gauge and set
gap to.030(0.76mm)if necessary. see Figure 26
5. Reinstall spark plug and tighten securely
NOTE:A resistor spark plug must be used for replacement.Contact a Sears Parts and Repair Center
for a replacement spark plug.
Carburetor
If you suspect your carburetor needs adjusted, see a Sears Parts and Repair Center, engine performance should not be
affected at altitudes up to 7000 feet (2134 meters). For operation at higher elevations, contact a Sears Parts and
Repair Center.
Engine Speed
WARNING:Avoid serious injury or death, DO NOT modify engine in any way, Tampering with
the governor setting can cause the engine and equipment to operate at unsafe speeds, NEVER tamper with factory
setting of engine governor, Running the engine faster than the speed set at the factory is dangerous.

MAINTENANCE

To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer, Follow these
instructions to prepare your snow thrower for storage:
WARNING:Drain fuel into an approved container outdoors, away from any open flame. Be
certain engine is cool. Do not smoke. Fuel left in engine during warm weather deteriorates and will cause
serious starting problems.
1. Remove All gasoline from the carburetor and the fuel tank to prevent gum deposits from forming on these parts
and harming the engine.
2. Run the engine until the fuel tank is empty and it stops due to lack of fuel.
3. Drain carburetor by pressing upward on bowl drain, located below the carburetor cover,
WARNING:Do not drain carburetor if using fuel stabilizer. Never use engine or carburetor
cleaning products in the fuel tank or permanent damage may occur.
NOTE: Fuel stabilizer (such as STA-BIL) is an acceptable alternative in minimizing the formation of fuel gum
deposits during storage, Add stabilizer to gasoline in fuel tank or storage container, Always follow mix ratio found
on stabilizer container, Run engine at least 10 minutes after adding stabilizer to allow it to reach the carburetor, Do
not drain carburetor if using fuel stabilizer.
4. Remove the spark plug and pour one ounce of engine oil through the spark hole into the cylinder. Cover spark
plug hole with a rag and crank the engine several times to distribute the oil. Replace spark plug.
Preparing Snow Thrower
1. When storing the snow thrower in an unventilated or metal storage shed, care should be taken to rustproof the
equipment, using a light oil or silicone,coat the equipment, especially any chains, springs, bearings and cables.
2. Remove all dirt from exterior of engine and equipment.
3. Follow lubrication recommendations in the Maintenance section of this manual.
4. Store equipment in a clean dry area.
Tire Pressure
Before operating, Check the pressure and reduce pressure to between 15 psi and 20 psi
If the tire pressure is not equal in both tires, the unit may pull to one side or the other.
OFF-SEASON STORAGE
Preparing Engine
WARNING: Never store snow thrower with fuel in tank indoors or in poorly ventilated
areas, where fuel fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes
dryer or gas appliance.
NOTE:It is important to prevent gum deposits from forming in essential fuel system parts of the engine such
as the carburetor, fuel filter, fuel hose or tank during storage.
CAUTION:Alcohol blended fuels(called gasohol or using ethanol or methanol)can attract moisture which
leads to separation and formation acids during storage. Acidic gas can damage the fuel system of an engine
while in storage
