• Remove the oil filler cap/dipstick and wipe the dipstick clean.
• Insert the cap/dipstick into the oil filler neck, but do NOT screw it in.
• Remove the oil filler cap/dipstick. If the level is low, slowly add oil (5W-30, with a minimum classification of SF/SG) until oil level registers between high (H) and low (L). NOTE: Do not overfill. Overfilling with oil may result in engine smoking, hard starting or spark plug fouling.
• Replace and tighten cap/dipstick firmly before starting engine.

Gasoline

Use automotive gasoline (unleaded or low leaded to minimize combustion chamber deposits) with a minimum of 87 octane. Gasoline with up to 10% ethanol or 15% MTBE (Methyl Tertiary Butyl Ether) can be used. Never use an oil/gasoline mixture or dirty gasoline. Avoid getting dirt, dust, or water in the fuel tank. DO NOT use E85 gasoline.

• Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area where the engine is refueled or where gasoline is stored.
• Do not overfill the fuel tank. After refueling, make sure the tank cap is closed properly and securely.
• Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before starting the engine.
• Avoid repeated or prolonged contact with skin or breathing of vapor.

1. Clean around fuel fill before removing cap to fuel.

2. Fill tank until fuel reaches 1⁄2 inch below the bottom of the filler neck to allow space for fuel expansion. Be careful not to overfill.

Starting The Engine

NOTE: Allow the engine to warm up for a few minutes after starting. The engine will not develop full power until it reaches operating temperatures.

1. Make certain both the auger control and drive control are in the disengaged (released) position.
2. Insert key into slot. Make sure it snaps into place. Do not attempt to turn the key.

NOTE: The engine cannot start without the key fully inserted into the ignition switch.

Stopping The Engine

After you have finished snow-throwing, run engine for a few minutes before stopping to help dry off any moisture on the engine.

1. Move throttle control to OFF position.
2. Remove the key. Removing the key will reduce the possibility of unauthorized starting of the engine while equipment is not in use. Keep the key in a safe place. The engine cannot start without the key.
3. Wipe any moisture away from the controls on the engine.

Using Snow Blower to Clear Snow

1. Start the engine following starting instructions.
2. Allow the engine to warm up for a few minutes as the engine will not develop full power until it reaches operating temperature.
3. Rotate the chute assembly to the desired direction, away from bystanders and/or buildings.
4. Making certain no bystanders or obstacles are in front of the unit, squeeze the auger control completely against the upper handle to fully engage the auger.
5. While the auger control is engaged, squeeze the drive control completely against the upper handle to engage the wheels. Do not “feather” the drive control.
6. As the snow blower starts to move, maintain a firm hold on the handle, and guide the snow blower along the path to be cleared.
7. Release the auger and drive controls to stop the snow throwing action and forward motion. NOTE: Your unit is equipped with a clutch in the transmission. If the wheels stop turning while trying to discharge large volumes of snow, immediately disengage the drive control and allow the rotating auger to discharge snow from the housing. Reduce the clearing width and continue operation.
8. On each succeeding pass, readjust the chute assembly to the desired position and slightly overlap the previously cleared path.

SERVICE AND MAINTENANCE

Engine Maintenance
