SECTION 2: ASSEMBLING YOUR SNOW THROWER
Unpacking
Remove staples from the top, sides, and ends of
the shipping crate. Set panels aside to avoid tire
damage or personal injury.
Remove and discard plastic bag that covers unit.
Roll the unit out of the crate.
Check the crate for loose parts before discarding.
Loose Parts
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.
See Figure 1. Store these safely until needed.
Figure 1
IMPORTANT:
NEVER replace the auger shear bolts
with standard hex bolts. Any damage to the auger
gearbox or other components from using standard bolts
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: All references in this manual to the left or right
side of the snow thrower is from the operating position
only. Exceptions, if any, will be specified.
Assembling Handle
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
Figure 2
Secure the upper handle and lower handle with the
two plastic wing nuts, cupped washers and carriage
bolts previously removed. Attach these hardware
on the lower hole in the handles. 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 Crank
Remove the hairpin clip from the upper chute crank
and slide the upper chute crank through the upper
chute crank bracket and into the lower chute crank.
A pair of pliers may help in this job.
Align the two holes on both chute cranks and insert
the hairpin clip removed earlier, through these
holes. See Figure 3.
