handle. Hold the “Z” fitting with the pliers, not the 
cable, to avoid damaging the cable.

NOTE: 

The upper hole in the control handle provides

for adjustment in belt tension. Refer to page 9 of this
manual for instructions.

Assembling Discharge Chute  

Turn the chute crank until the chute faces straight 
to the front. See Figure 4 .

Remove the hand knob, flat washer and carriage 
bolt from the upper chute. See Figure 4.

Pivot the upper chute up and over the lip of the 
lower chute. This will eliminate any gap between 
the upper and the lower chutes. Secure with 
hardware just removed.

Auger Control Handle 

Located on the upper handle, the auger control handle 
is used to engage and disengage the auger. The snow 
thrower is designed to propell by the rotation of the 
auger. Pull the control handle back against the upper 
handle to engage the auger; release to disengage.

Chute Crank 

Located on right side of dash panel, the chute crank 
determines the direction that snow will be discharged. 
Turn clockwise to discharge snow to the left; turn 
counterclockwise to discharge to the right.
