Boom, Stick, Bucket, Swing Movement And Travel
Engine setting at high idle ... 2300 ± 50 rpm
Oil temperature ... 55 ± 5°C (131 ± 9°F)
Check the specified relief valve pressure settings.
Cycle times are measured with the following attachments: 5.1 m (16 ft 8 inch) boom, 2.6 m (8 ft 6 inch) and SAE 0.65 m3 (0.85 yd3) empty bucket .
Place the power mode selector switch in the Power Mode position.
Place the work mode selector switch in the Boom Priority Mode position.
Boom raise cycle time is the time period that elapses while the boom travels from the ground level to maximum boom height. The stick cylinder and the bucket cylinder must be fully retracted. Start with the bucket on the ground.
Boom raise cycle time ... 2.9 to 3.5 seconds
Boom lower cycle time is the time period that elapses while the boom travels from maximum boom height to ground level. The stick cylinder and the bucket cylinder must be fully retracted.
Boom lower cycle time ... 1.9 to 2.5 seconds
Stick out cycle time is the time period for the full retraction of the stick cylinder. Start with the boom parallel to the ground and close the bucket.
Stick out cycle time ... 2.2 to 2.8 seconds
Stick in cycle time is the time period for the full extension of the stick cylinder. Start with the boom parallel to the ground and close the bucket.
Stick in cycle time ... 2.3 to 2.9 seconds
Bucket close cycle time is the time period for the full extension of the bucket cylinder.
Bucket close cycle time ... 3.4 to 4.0 seconds
Bucket open cycle time is the time period for the full retraction of the stick cylinder.
Bucket open cycle time ... 1.7 to 2.3 seconds
Swing cycle time is the time period for a 180 degree swing movement of the upper structure. Park the machine on a level, hard surface. Position the machine at maximum reach. Use an empty bucket. Begin the test with the upper structure in motion.
Swing cycle time ... 5.1 seconds maximum
Travel cycle time is the time period that elapses while the machine travels 20 m (65 ft 7 inch) after a preliminary 5 m (16 ft 5 inch) run.
Travel cycle time at HIGH speed ... 16.1 second maximum
Travel cycle time at LOW speed ... 26.1 seconds maximum
