OPERATIONAL PERFORMANCE TEST / Excavator Test HYDRAULIC CYLINDER CYCLE TIME Summary: 1. Measure the cycle time of boom, arm and bucket cylinders and check the performance of front attachment systems (from main pump to each cyliner). 2. The bucket must be empty. Preparation: 1. Mmeasure at the position as follows. Measurement of the cycle time of boom cylinders: With the arm fully retracted and the bucket fully extended, lower the bucket to the ground. Measurement of the cycle time of arm cylinder: Retract or extend the bucket cylinder so that the arm and bucket teeth are vertical to the ground. Set the arm so that the encter of arm operation is vertical.
Measuremnt of the cycle time of bucket cylinder: Adjust each cyliner of boom and arm so that the center of bucket full stroke is vertical. 2. Maintain the hydraulic oil temperature at 50 ± 5 ° C (122 ± 41 ° F). T105-06-03-018 0.5 m T1V1-04-05-005 T105-06-03-020 T4-4-14
