ADJUSTMENTS
MOTION CONTROL LINKAGE ADJUSTMENT:
1. This adjustment must be made with the drive wheels rotating. Raise rear of the unit and
block it up so the wheels are free to rotate. CAUTION: Keep hands, feet and clothing away
from rotating tires.
2. Tilt seat forward and remove the seat rod from seat so the seat can rotate down onto the
frame. Make sure the seat is adjusted toward the rear of the unit so it clears the controls on
the console.
3. Place a 2x4 board approximatly 10 to 12 inches long between the foot plate and the center
of the seat to engage the seat safety switch. NOTE: You may want to cover the end of the 2x4
with a rag to protect the seat from marring.
4. The reverse spring detent must be adjusted correctly before the motion control linkages
may be adjusted.(See reverse spring detent adjustment section.)
5. Loosen the nuts directly behind each ball joint on both rods that connect the pump arm to
the motion control assemblies. (See Fig 5 )
6. Start the engine. The park brake must be engaged and the motion control levers must be
in the neutral slot (See figure 6 page10) to start the engine. Run engine at approximately 1/
2 throttle.
7. Release park brake to allow wheels to rotate. CAUTION: Keep hands, feet and clothing
away from rotating tires.
8. Begin with either side and put the motion control lever into the neutral position. Adjust the
motion control linkage by rotating the double nuts on the rod in the proper direction until the
wheel stops rotating (See Fig 5 ).
Move the motion control lever forward then into the neutral position and place it into the
neutral slot. The wheel must be stopped completely at this point. Now do the same in reverse
and release the lever. The lever should return to neutral on its own. If not see reverse spring
detent adjustment section.
9. Run engine at full throttle to make sure wheels do not rotate. Readjust if any rotation
occurs.
10. Repeat on the opposite side and tighten nuts against ball joints.
11. Remove the 2x4 board and make sure the seat wiring is connected to the wiring harness.
WARNING: Seat must be connected for safety interlock system to properly function.
