Spark Plug Access

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.

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

If your home 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.

Move Choke Control to “Full” position.

Push Primer three (3) times, making sure to cover vent hole when pushing.Connect power cord to switch box on dash panel. Plug the other end of power cord into a three-prong 120-volt, grounded, AC receptacle.

Push starter button to crank engine. As you crank the engine, move choke lever 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

Move choke lever 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 for cold engine start.

If engine is warm, push primer button only once.

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

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.

As engine warms up and begins to operate evenly, rotate choke lever slowly to OFF position. If engine falters, return to FULL choke, then slowly move to OFF position.
