RH MOTION CONTROL ADJUSTMENT

f)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.

g)The reverse indicator spring must be correct before the following adjustments can be made. See Section 4.2.9.

h)Bring the RH motion control lever into the neutral position. Adjust RH pump control rod length by rotating the double nuts on the rod in the appropriate direction until the wheels slightly creep in reverse (See Figure 11). Move the motion control lever to the reverse position and while applying slight pressure to the lever, allow the reverse indicator spring to bring the levers back to neutral. The wheel must stop turning or slightly creep in reverse.

NOTE: The motion control lever needs to be in neutral while making any necessary adjustments.

The left rod assembly controls the left wheel and the right rod assembly controls the right wheel.

i)Bring the LH motion control lever into the neutral position. Adjust the LH pump control rod length by rotating the tracking adjustment knob in the appropriate direction until the wheels slightly creep in reverse. Move the motion control lever to the reverse position and while applying slight pressure to the lever allow the reverse indicator spring to bring the levers back to neutral. The wheel must stop turning or slightly creep in reverse. See Figure 12.
