Yard-Man E643E, E663H manual To Stop Engine, To Engage Drive, To Engage Augers

•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 FULL position.

•Move throttle control to FAST (Rabbit) position.

•Fully depress the primer three times, making sure to cover the vent hole went pushing.

NOTE: Do NOT use the primer when restarting a warm engine. Doing so will cause the engine to “flood.”

•Push starter button on top of the engine.

•When engine starts, release starter button, and move choke gradually to OFF. If engine falters, move choke momentarily 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.

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

To Stop Engine

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

•Move the throttle control to the STOP or OFF position.

To help prevent starter freeze-up:

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 snow thrower’s 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.

•Remove the 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 the ignition key in a safe place. The engine will not start without the ignition key.

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

To Engage Drive

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

•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.

•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,

Auger Control Test

IMPORTANT: Perform the following test before operating the snow thrower for the first time and at the start of each winter season.

Check the adjustment of the auger control as follows:

•When the auger control is released and in the disengaged “up” position, the cable should have very little slack, but should NOT be tight.

WARNING: Do not over-tighten the cable. Over-tightening may prevent the auger from disengaging and compromise the safety of the snow thrower.
