9. Figure 6: Install plastic handle (item 5) over the
rotation handle (item 6).
10. Figure 6: Insert assembled rotation tube
(item 1) inside the rotation worm assembly
(items 2). Align holes and insert a 10-24NC x 1''
allen socket head capscrew (item 3) making
sure the capscrew sinks into the worm. Secure
with a nylon insert locknut (item 4). Adjust the
height of the handle support according to your
needs and shorten if necessary.
11. Figure 6: Insert the rotation handle (item 6)
inside the grommet and inside the rotation tube
(item 1). Select desired length, align nearest
holes and secure with a 4mm x 80mm hairpin
(item 8).
12. Figure 7: Adjust the rotation tube support
(item 3) and the rotation worm support (item 1)
by moving them toward the chute so the
rotation worm is engaged between the gear
teeth of the chute. Make sure the rotation
worm and the bushings are well aligned.
Tighten slightly the three 1/4"NC x 3/4" bolts
and the three 1/4"NC nuts (item 2).
13. Figure 7: Rotate the chute completely to the
right then to the left using the rotation handle
(item 4).
• If the chute is too hard to turn it's because the
rotation worm is engaged too deep between
the gear teeth, move the worm slightly away
from the gear teeth and try again.
• If the chute rotates with difficulty because the
teeth do not engage or engage incorrectly,
adjust the rotation handle support toward the
chute and redo the steps.

ASSEMBLY
14. Figure 7: Make sure the worm engages
completely when it reaches the end of the
chute gear. The rotation handle is well
adjusted when the chute rotates easily
without straining. Tighten firmly the three
1/4"NC x 3/4" bolts and the three 1/4"NC
nuts (item 5).
15. Figure 7: After the snowblower is mounted
to the tractor, you may adjust the rotation
handle position and height to a comfortable
and safe operating position. When the
desired position is set for working position,
make sure the rotation handle is not
interfering with any parts of the tractor while
on transport position (snowblower raised to
maximum). Tighten firmly the 3/8"NC x 1/2''
square head setscrew 3/8"NC x 1/2"
(item 5) to the desired height. Then tighten
firmly the 3/4"NC x 1 1/2" bolt (item 6) to
the desired position.
16. Lubricate the rotation worm.
NOTE: To insure the manual rotation operates
properly, the handle support (fig.6, item 7) must
be positioned the closest possible to the top link
mounting point of the three point hitch while
making sure it does not come into contact with
the operator's seat when the snowblower is fully
raised.
injury, check the full lifting range of the
snowblower, to ensure that the chute
rotation handle is clear of the operator's area
when the snowblower is in raised position.
