Electric Starter (If Equipped)

WARNING: The electric starter is equipped with a grounded three-wire power cord and plug and is designed to operate on 120 volt AC household current. It must be used with a properly grounded three-prong receptacle at all times to avoid the possibility of electric shock. Follow all instructions carefully prior to operating the electric starter.

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.

If your home electrical system is grounded, but a three-hole receptacle is not available, one should be installed by a licensed electrician before using the electric starter.

If you have a grounded three-prong receptacle, proceed as follows:

Rotate choke knob to OFF position and do not prime engine.

Connect power cord to switch box on engine. Plug the other end of power cord into a three-hole, grounded 120 volt AC receptacle.

Push starter button on top of the engine to crank engine. As you crank the engine, move choke knob to FULL choke position.

When engine starts, release starter button, and move choke gradually to OFF. If engine falters, move choke immediately to FULL and then gradually to OFF.

When disconnecting the power cord, always unplug from the three-prong receptacle first and then from the snow thrower.

Recoil Starter

Rotate choke knob to FULL choke position (cold engine start). If engine is warm, place choke in OFF position instead of FULL.

Push primer button two or three times. If engine is warm, push primer button once only.

NOTE: Always cover vent hole in primer button when pushing. Additional priming may be necessary for first start if temperature is below 15°F.

Grasp starter handle and pull rope out slowly, until it pulls slightly harder. Let rope rewind slowly.

Pull starter handle rapidly. Do not allow handle to snap back. Allow it to rewind slowly while keeping a firm hold on the starter handle.

Repeat the previous steps until engine starts.

To Stop Engine

Run engine for a few minutes before stopping to help dry off any moisture on the engine.

To help prevent possible freeze-up of starter, proceed as follows.

Electric Starter:

Connect power cord to switch box on engine, then to 120 volt AC receptacle. With the engine running, push starter button and spin the starter for several seconds. The unusual sound made by spinning the starter will not harm engine or starter. Disconnect the power cord from receptacle first, and then from switch box.

Recoil Starter

With engine running, pull starter rope with a rapid, continuous full arm stroke three or four times. Pulling the starter rope will produce a loud clattering sound, which is not harmful to the engine or starter.

Move throttle control to “stop” or “off” position.

Remove ignition key. Do not turn key. Disconnect the spark plug wire from the spark plug to prevent accidental starting while equipment is unattended.

NOTE: Keep it in a safe place. Engine will not start without ignition key.

Wipe all snow and moisture from the carburetor cover in the area of the control levers. Also, move control levers back and forth several times.

To Engage Drive

With the engine running near top speed, move shift lever into one of the six FORWARD positions or two REVERSE positions. Select a speed appropriate for the snow conditions that exist.

NOTE: Use slower speeds until you are familiar with the operation of the snow thrower.

Squeeze the traction control against the right handle and the snow thrower will move. Release it and the drive motion will stop.

IMPORTANT: NEVER move shift lever without first releasing the traction control. Doing so will cause premature wear to drive system’s friction wheel rubber.

To Engage Augers

To engage the augers and start the snow throwing action, squeeze the auger control against the left handle.

To disengage power to the augers, release both the auger control and the traction control, if engaged.

Tire Chains (If Equipped)

Tire chains should be used whenever extra traction is needed.
