Attaching Clutch Cables
(Boxed & Crated Unit)
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, insert "Z"
fitting into hole in clutch grips. See Figure 11.
Cable Should
Be Straight

• 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 9.
• 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.
The cable should have very little slack, but
IMPORTANT:
should NOT be tight. An overtightened cable may
prohibit the auger and drive from disengaging.
WARNING:
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
• 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 12.
• 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.
NOTE:
Lock nuts cannot be threaded onto a bolt by
hand. Tighten with two 7/16" or adjustable wrenches.
