Primer

Vent Hole

•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:

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

•Rotate choke knob to ON position.

•Push primer button three times,

making sure to cover vent hole when pushing.

• 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. Always cover vent hole in primer button when pushing. At temperatures below 15°F, additional priming may be necessary .

•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 prevent possible freeze-up of starter:

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 recepta- cle 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 key 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 Wheel Drive

•With the engine running near top speed, move shift lever to one of the eight positions to set desired speed and direction. Select speed appropriate for the snow conditions that exist.

NOTE: Use slower speeds in higher snow and/or until you are familiar with the snow thrower operation.

•Squeeze traction control against the right handle to move the snow thrower; release it to stop.

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

To Engage Augers

•To engage augers and start snow throwing, 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.

Operating Tips

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

WARNING: The temperature of the muffler

and the surrounding areas may exceed 150°F. Avoid these areas.

•If possible, remove snow immediately after it falls.

•Discharge snow downwind whenever possible.

•Slightly overlap each previous path.

•Set the skid shoes 1/4" below the shave plate for normal usage. Adjust it upward for hard-packed snow and downward when using on gravel or crushed rock.
