• Models 614, 644, 664, and 6A4: Thread the ferrule
onto the shift rod, up or down the shift rod and align
with the far hole on the narrow side of the shift lever
assembly behind the handle panel. See Figure 8.
Figure 8
• Secure the ferrule to the shift arm assembly with
the flat washer and hairpin clip.
Attaching Clutch Cables
(Hardware D)
Z fittings with jam nuts might be already inserted in
each control lever (on the handle panel) at the factory.
To attach the cables to the Z fittings, proceed as
follows:
NOTE: Two extra jam nuts are included in the
hardware pack in the event either are lost during
shipping.
• If Z fittings are not already attached, thread hex
nuts onto the “Z” fittings and insert “Z” fitting into
hole in clutch grips. See Figure 9.
• Route the left cable between engine and speed
selector plate and then between handle panel and
clutch lever pivot rod before threading onto the left
“Z” fitting.
Figure 9
• Assemble the right cable in the same manner.
• Both cables should have minimal slack, but not
tight.
• If Z fittings are already attached, thread the jam
nuts all the way up each of the Z fittings, toward the
handle panel.
• Make certain all cables are in the grooves of the
cable roller guides in the lower rear of the unit, one
on each side. Refer to Figure 6.
• Thread the coupling end of the cable onto the
threaded portion of the Z fitting until the rubber
bumper (located on the underside of the clutch
lever) only lightly contacts the upper handle.
IMPORTANT: The cable should have very little slack, but
should NOT be tight. An overtightened cable may
prohibit the auger and drive from disengaging.
WARNING: Over-tightening the cable
may prohibit the auger and drive from
disengaging and compromise the safety
of the snow thrower. Do NOT overtighten
the cable.
• Once properly adjusted, tighten the jam nut against
the coupling end of the cable to lock it in position.
NOTE: Refer to Auger Control Test in the Operation
Section prior to operating your snow thrower. Read and
follow all instructions carefully and perform all
adjustments to verify your snow thrower is operating
safely and properly.
Attaching the Chute Assembly
(Hardware F)
• Place chute assembly over chute opening, with the
opening in the chute assembly facing the front of
the unit.
• Place chute flange keepers beneath lip of chute
assembly, with the flat side of chute flange keeper
facing downward. See Figure 10.
• Insert hex bolt up through chute flange keeper and
chute assembly and secure with hex lock nut. After
assembling all three chute flange keepers, tighten
all nuts and bolts securely. Do not overtighten.
