•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 auger and drive clutch levers are in the disengaged (released) position.

•Move throttle control to FAST (Rabbit) position. Insert ignition key into slot. 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

•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.

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.

Two notable models from their lineup are the Yard-Man E643E and the E663H, both designed to meet the diverse needs of homeowners and garden enthusiasts.

The Yard-Man E643E is a lightweight yet powerful electric lawn mower. It features a 14-inch cutting deck, making it perfect for small to medium-sized yards. The mower is powered by a potent 12-amp electric motor that provides the efficiency of a gas mower without the noise and emissions. One of the standout features of the E643E is its adjustable cutting height, which ranges from 1 inch to 3 inches, allowing users to customize the grass height according to their preferences and seasonal needs. This model is equipped with a rear bagger that collects clippings for easy disposal, ensuring a clean and manicured appearance for your lawn.

On the other hand, the Yard-Man E663H is a self-propelled gas mower built for those who require a more robust solution for larger lawns. It features a 21-inch steel cutting deck, which allows for wider cutting paths, reducing mowing time. The E663H is powered by a reliable Honda engine, known for its durability and efficiency.

An ergonomic handle with variable speed control makes it comfortable for users to operate, while the rear-wheel drive enhances traction, especially on uneven terrains.

Both models incorporate innovative technologies that enhance user experience. The E643E’s electric motor ensures quiet operation, making it ideal for residential areas without the disturbance typically associated with gas mowers. The E663H, meanwhile, utilizes a swingback blade system that enhances cutting efficiency and provides a clean cut while reducing the risk of blade damage from obstacles.
