If the connector is not properly assembled, the shift rod will pivot and you will not be able to change speeds or change directions.

•Insert “Z” fitting (Hardware A) into hole in clutch grips. See Figure 11. Two extra jam nuts are included in the hardware pack in the event either are lost during shipping.

•Thread the jam nuts all the way up each of the “Z” fittings, toward the handle panel. See Figure 11.

•Make certain all cables are in the grooves of the cable roller guides located in the lower rear of the unit, one on each side. See 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.

•Raise the upper handle assembly until it locks over the lower handle. See Figure 4.

•Observe the lower rear area of the snow thrower to be sure both cables are aligned with roller guides.

•Secure the upper handle and lower handle with the two plastic wing knobs, cupped washers and carriage bolt (eyebolt on the left side) previously removed. See Figure 4.

•Adjust the eyebolt on the chute directional control so the rod does not come into contact with the engine by moving the hex nut against the handle (if necessary). Retighten the wing nut to secure the directional control in this position.

•Slide the connector down over the end of the lower shift rod. See Figure 4. Tap the connector until it locks on the lower shift rod.
