ASSEMBLY

Read and follow the assembly and adjustment
instructions for your snow thrower. All fasteners
are in the parts bag. Do not discard any parts or
material until the unit is assembled.
WARNING: Before doing any
assembly or maintenance to the
snow thrower, remove the wire
from the spark plug.
NOTE: In this instruction book, left and right
describe the location of a part from the oper-
ator's position behind the unit.
NOTE: Torque is measured in foot pounds
(metric N.m). This measurement describes
how tight a nut or bolt must be. The torque is
measured with a torque wrench.
NOTE: Illustrations begin on page 3.
NOTE: To assemble the following loose
parts, use the fasteners shown at full size in
Figure 22.

6. Install the eye bolt (11) through the lower
hole on the left side of the handles.
7. Install the flatwasher (10) and the locknut
(9) loosely on the eye bolt (11).
8. (Figure 4) Carefully remove cotter pin (12),
clevis pin (13), universal joint pin (14), and
universal joint (16) from the crank rod as-
sembly (15).
9. Mount the universal joint (16) into the end
of the worm gear (17). Make sure the large
holes are aligned.
10. Insert universal joint pin (14). Make sure
opening in universal joint pin (14) is aligned
with small opening in universal joint (16).
11. Mount the yoke end of crank rod (15)
around the universal joint (16). Fasten with
clevis pin (13) and cotter pin (12). Spread
ends of cotter pin (12) to lock in place.

Make sure eye bolt (11) is properly aligned
and the crank (18) can freely rotate.
13. Tighten all handle fasteners.
Check The Cables
1. (Figure 5) Check the traction drive cable
(1) and the auger drive cable (2). If the bot-
tom of the cables have become discon-
nected, reinstall the cable springs. Make sure
the long spring (3) is attached to the traction
drive and the short spring (4) is attached to
the auger drive.
2. (Figure 6) If the top of the cables (5) have
become disconnected from the drive levers
(6), attach the cables (5) to the "Z" fitting
(7).
How To Set The Skid Height (Figure 2)
The snow thrower is equipped with height ad-
justable skids (7) mounted on the outside of the
auger housing (4). To adjust the height of the
skids, see "How To Adjust The Height Of The
Skids" in the Maintenance section.
How To Prepare The Engine
