NOTE The measuringtime of the cylinder cycle does not include the cushion stroke times. Only measuretime up to the beginning of the cushion stroke. Movethe machineto a firm, level testing area. , 2. Place the machinethrottle control to "HIGH" idle and The KPSSWork Mode Switch to "H" Mode. See Figure 3.4.

Fully extend BoomCylinder. SeeFigure 3.5. Fully retract Bucket Cylinder. SeeFigure 3.5. Fully extendthe Arm(retracting cylinder). At full stroke of the control, bring the armall the way in (extending cylinder) and measurethe time it takes for the arm cylinder to reach the cushion stroke. Recordthe time. See Figure 3.6. 7. At full stroke of the control, fully extendthe arm (retracting cylinder) andmeasurethe time takes until the cylinder reaches the cushion stroke. Recordthe time. See Figure 3.6. 8. Repeat steps 6 and 7 two more times. Average the recorded times and comparethe average to the Arm Cylinder Cycle Time Specification Chart. 9. Repeat steps 5 through 8 in the "FC" mode. Comparethe average readings to the Arm Cylinder Cycle Time Specification Chart.
