Swivel (pivot head)

5.Standard nut (shown against swivel)

Note the order of the standard nut and lock nut (no nut on the cable anchor side of the swivel).

10.Release hold on the caliper lever and cable. The wheel hub should turn by hand in both directions relative to the caliper; some friction/resistance is acceptable.

11.If there is no movement between the hub rotor and the caliper then back off the standard nut one turn from the swivel and repeat step 10 (drive release valves must be in the “released” position on the hydros).

12.If the hub rotor moves very freely relative to the caliper, then tighten the standard nut one turn against the swivel and repeat step 10.

13.Once step 10 is achieved, hold the threaded rod end with a tool and tighten the lock nut against the standard nut. Do Not allow the cable to turn when the nuts are tightened.

14.Rotate the drive wheel release handle to the “operating” position. Refer to the Drive Wheel Release Valves section in Operation.

15.Repeat on the opposite side of machine.

16.Install the rear tires and torque lug nuts to 90-95 ft-lb (122-129 N-m).

17.Remove jack stands.

Electric Clutch Adjustment

No adjustment necessary.

Motion Control Linkage Adjustment

Located on either side of the fuel tank, below the seat are the pump control linkages. Rotating the pump linkage with a 1/2 inch wrench allows fine tuning adjustments so that the machine does not move in neutral. Any adjustments should be made for neutral positioning only.

WARNING

Engine must be running and drive wheels must be turning so motion control adjustment can be performed. Contact with moving parts or hot surfaces may cause personal injury.

Keep fingers, hands, and clothing clear of rotating components and hot surfaces.

1.Prior to starting the engine, push the deck lift pedal and remove the height of cut pin. Lower deck to the ground.

2.Raise the rear of machine up and support with jack stands (or equivalent support) just high enough to allow drive wheels to turn freely.

3.Remove the electrical connection from the seat safety switch, located under the bottom cushion of the seat. The switch is a part of the seat assembly.

4.Temporarily install a jumper wire across the terminals in the connector of the main wiring harness.

5.Start engine. Brake must be engaged and motion control levers out to start engine. Operator does not have to be in the seat because of the jumper wire being used. Run engine at full throttle and release brake.

6.Run the unit at least 5 minutes with the drive levers at full forward speed to bring hydraulic oil up to operating temperature.
