Snow Thrower Troubleshooting

PROBLEM

No snow through thrower’s discharge chute.

• Discharge chute and/or auger is clogged

SOLUTION

• Disengage the auger and drive controls, stop the engine, wait ten seconds for the auger to stop rotating, then using the clean-out tool provided, remove the snow clogging the chute.

• Shear pin(s) are missing or broken and need to be replaced.

• Auger is not rotating

Snow not completely removed from surface

• Skid shoe needs adjustment • Disengage the auger and drive controls, stop the engine, wait ten seconds for the auger to stop rotating. Loosen the two hex nuts on the skid show on either side of the snow thrower.

Raise the skid shoes so the entire bottom surface of the skid show rests on the ground evenly. Retighten the hex nuts on both sides. This adjustment allows the auger to come into closer contact with the ground surface.

Snow not evenly removed from surface

• Tires not inflated evenly • Check tire pressure, inflate both tires to the same pressure recommended (15-20 psi) so auger is level on the ground.

• Make sure that skid shoes are at same height.

• Skid shoes not correctly adjusted

Cannot adjust the discharge chute

• Moving parts are frozen • In extreme cold environments some controls and moving parts may freeze. Do not use excessive force to operate frozen controls. Allow the engine to run for several minutes to warm up and thaw frozen parts.

Snow thrower continually clogs

• Machine does not propel itself forward • Operate at a slower pace to allow the snow thrower to dispel snow through the discharge chute. Forcing the snow thrower to move faster than it can remove the snow will result in clogged auger and/or discharge chute. Do not overload the thrower in extremely heavy or wet snow.

FUEL IN TANK INDOORS

Do not store in poorly ventilated areas, or near furnace, water heater, clothes dryer or gas appliance.

1. For short term storage wait for the engine to cool, then clean the engine with a clean cloth.

2. When the snow thrower is to be stored for longer than 30 days, prepare the engine for storage by emptying the fuel tank and draining all fuel lines.

Note: As an alternative to draining the fuel system, a fuel stabilizer can be added to a full gas tank. Do not drain the carburetor if using a fuel stabilizer.

3. Run the engine until all the fuel has been consumed and the engine stops.

4. Drain the carburetor (see Figure 26). Remove the 6 hex bolts on the muffler, and slide the mufffler cover off of the engine to access the carburetor.

5. Clean out area around spark plug and remove. Pour one tablespoon of engine oil into the cylinder through the spark plug hole. Reinstall the spark plug, but leave the spark plug wire disconnected. Pull recoil starter handle to distribute oil in the cylinder. Stop after one or two revolutions when you feel the piston start the compression stroke (when you start to feel resistance).

6. Apply a thin coat of rust preventive oil to all uncoated metal parts.

7. Cover and store in a dry, well-ventilated area out of reach of children.
