Attaching Clutch Cables

(Boxed & Crated Unit) (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, insert “Z” fitting into hole in clutch grips. See Figure 11.

Figure 11

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.

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 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.
