Shift Rod Adjustment

To adjust the shift rod, proceed as follows.

•Remove the hairpin clip and slide the connector up to separate the upper shift rod from the lower shift rod. See Figure 11.

•Place shift lever in the sixth (6) Forward position.

•Rotate the shift arm counterclockwise (from the operator’s position) as far as it will go.

•Thread the upper shift rod downward until the elbow on its lower end aligns with the hole found in the lower shift rod.

•Reconnect the upper shift rod to the lower shift rod by reinserting the hairpin clip removed earlier and sliding the connector back down into place.

IMPORTANT: Make certain to check for correct adjustment of the shift rod as instructed under the heading Final Adjustments on page 8 of this manual, before operating the snow thrower.

Auger Control Adjustment

Refer to Auger Control Test on page 9 of this manual to adjust the auger control.

Skid Shoes

The space between the shave plate and the ground can be adjusted. For close snow removal, place skid shoes in the low position. Use middle or high position when area to be cleared is uneven.

•Adjust skid shoes by loosening the four hex nuts and carriage bolts and moving skid shoes to desired position. Make certain the entire bottom surface of skid shoe is against the ground to avoid uneven wear on the skid shoes. Retighten nuts and bolts securely. See Figure 12.

WARNING: Do not operate this snow thrower on gravel as loose gravel can be easily picked up and thrown by the auger causing injury to the operator and/or damage to the snow thrower.

Drive Wheels

The wheels may be adjusted for two different methods of operation. The adjustment is made by placing the click pins in one of two different holes on the right side of the unit.

One Wheel Driving—Insert the click pin only through the outside hole of the axle (NOT the rim) on the right side of the snow thrower. This position gives power drive to the left wheel only, making the unit easier to maneuver.

Both Wheels Driving—Insert the click pin through the hole in the hub of the rim and the INSIDE hole on the snow thrower’s right axle. This position is good for heavy snow as there is power drive in both wheels.

IMPORTANT: NEVER operate the snow thrower with the click pin inserted through both the RIM and the OUTSIDE HOLE in the axle. Doing so can result in serious damage to the drive system.

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.

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.
