SECTION 2:  LOOSE PARTS 

The snow thrower is shipped with following loose parts in the carton. Please remove all loose parts from the carton 
before discarding it. See Figure 1 to identify the parts noting that these parts may be referred to again in the 
following sections of this manual. Part numbers are shown in parentheses.

SECTION 3:  ASSEMBLING YOUR SNOW THROWER

NOTE: 

Any reference in this manual to the left or right

side of the snow thrower is observed from the
operator’s position.

IMPORTANT:

 Make any final adjustments as instructed 

later on in this section BEFORE operating your snow 
thrower. 

WARNING: 

Disconnect the spark plug wire 

and ground it against the engine to prevent 
unintended starting.

Remove the lower two plastic wing knobs, cupped 
washers and carriage bolts from the lower handle. 
See Figure 2.

Figure 2

Raise the upper handle assembly until it locks over 
the lower handle. See Figure 2 and Figure 3.

Look at the lower rear of snow thrower frame to be 
sure both cables are aligned with roller guides.

Secure the upper handle and lower handle with the 
two plastic wing knobs, cupped washers and 
carriage bolts previously removed. See Figure 3.

Figure 3

Slide the shift rod connector down over the end of 
the lower shift rod. See Figure 3. Tap the connector 
until it locks on the lower shift rod.

NOTE: 

If the connector is not properly assembled, the

shift rod will pivot and you will not be able to change
speeds or change directions.

Wing Knobs

Connector

AUGER SHEAR BOLTS

The augers are secured to the auger shaft with two shear bolts and 
hex lock nuts. If you hit a foreign object or ice jam, the snow thrower 
is designed so that the bolts may shear. Two replacement shear 
bolts and nuts are provided for your convenience. Store in a safe 
place until needed.

IMPORTANT:

 NEVER replace the auger shear bolts with standard 

hex bolts. Any damage to the auger gearbox or other components 
as a result of doing so will NOT be covered by your snow thrower’s 
warranty.
