hitachi — Maximum Swingable Slant Angle

OPERATIONAL PERFORMANCE TEST / Excavator Test MAXIMUM SWINGABLE SLANT ANGLE Summary: With the upperstructure swung 90 ° to the slope, check the maximum slant angle on which the upper- structure can swing to the uphill side. Preparation: 1. Check lubrication of the swing gear and bearing. 2. Load the bucket fully. In lieu of loading the bucket, weight (W) of the following specification can be used. ZAXIS160LC-3: W=900 kg (1984 lb) ZAXIS180LC-3: W=900 kg (1984 lb) With the arm fully retracted and the bucket fully extended, hold the arm top pin to the position flush with the boom foot pin height. 3. Climb a slope and swing the upperstructure 90 ° to the slope. 4.

Maintain the hydraulic oil temperature at 50 ± 5 ° C (122 ± 41 ° F). Measurement: 1. Select the following switch positions: Engine Control Dial Work Mode Fast Idle Digging Mode 2. Operate the swing lever to full stroke and swing the upperstructure to the uphill side. 3. If the machine can swing, measure the cab floor slant angle. 4. Increase the slope angle and repeat steps 2. and 3. Check both clockwise and counterclockwise. 5. Repeat the measurement three times. Evaluation: Refer to the Operational Performance Standard in Group T4-2. Remedy: Refer to the Troubleshooting B in Group T5-6. T105-06-03-011 T4-4-10 Power Mode Switch Auto-Idle Switch P Mode OFF
