SECTION 2: ASSEMBLING YOUR SNOW THROWER

Loose Parts

The augers are secured to the auger shaft with two shear pins and bow tie cotter pins. If you hit a foreign object or ice jam, the snow thrower is designed so that the pins may shear. Two replacement shear pins and cotter pins are provided for your convenience. Store in a safe place until needed. See Figure 1.

IMPORTANT: NEVER replace the auger shear pins with standard hex pins. Any damage to the auger gearbox or other components from using standard pins will not be covered by your snow thrower’s warranty.

Items Required For Assembly

1.Pair of pliers

2.Engine oil

3.Fresh gasoline

Before Assembly

Disconnect spark plug wire and ground it against the engine to prevent unintended starting.

NOTE: Reference to the right hand or left hand side of machine are observed from the operating position.

Assembling Handle

For shipping purposes, the upper handle is secured loosely to the lower handle with four wing nuts.

Remove the lower plastic wing nut, cupped washer and carriage bolt from each side of the lower handle. See Figure 2.

Raise the upper handle assembly until it locks over the lower handle.

Look at the lower rear of the snow thrower frame to be sure all the cables are aligned with the cable roller guides. Make sure the spring (found at the end of each cable) is attached to its actuator bracket.

Secure the upper handle and lower handle with the two plastic wing nuts, cupped washers and carriage bolts previously removed. See Figure 2.

Tighten the two wing nuts already in place on the upper holes and secure the handles firmly.

Slide the shift rod connector down over the end of the lower shift rod. Tap the connector until it locks over the lower shift rod. See Figure 2.

NOTE: If the connector is not properly assembled, the shift rod will pivot and you will not be able to change speeds or direction of movement.

Attaching Chute Directional Control

Remove the hairpin clip from the upper chute rod and slide the upper chute rod through the upper chute rod bracket and into the lower chute rod. A pair of pliers may help in this job.

Align the two holes on both chute rods and insert the hairpin clip removed earlier, through these holes. See Figure 2.

With the flange locknuts loosened on the lower chute crank bracket (see Figure 3) adjust the bracket so that the spiral on the chute crank fully engages the teeth on the chute assembly. Tighten the nuts on the lower chute crank bracket securely.
