SECTION 4: OPERATING YOUR SNOW THROWER

Before Starting

WARNING: Read, understand, and follow all instructions and warnings on the machine and in this manual before operating.

Gas And Oil Fill-up

Service the engine with gasoline and oil as instructed in the separate engine manual packed with your snow thrower. Read instructions carefully.

WARNING: Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel machine indoors or while the engine is hot or running. Extinguish cigarettes, cigars, pipes and other sources of ignition.

To Start Engine

NOTE: If unit shows any sign of motion (drive or augers) with the clutch grips disengaged, shut engine off immediately. Readjust as instructed in the Final Adjustments in the Assembly Section.

Attach spark plug wire to spark plug. Make certain the metal loop on end of the spark plug wire (inside the boot) is fastened securely over the metal tip on the spark plug.

Make certain the fuel shut-off valve, if so equipped, is in the OPEN (vertical) position.

Make certain the auger and drive controls are in the disengaged (up) position.

Move throttle control up to FAST position. Insert ignition key into slot and snap in place. See Figure 6. Be certain it snaps into place. Do not turn key.

NOTE: Engine will not start unless ignition key is inserted into ignition slot in carburetor cover.

Electric Starter (optional)

Determine that your house wiring is a three-wire grounded system. Ask a licensed electrician if you are not certain.

If your house wiring system is not a three-wire grounded system, do not use this electric starter under any conditions.
