VALVE GP-RADIATOR DRAIN 2254287 - Caterpillar

The operator is then instructed to raise the bucket slowly:
Table 32
RAISE BUCK SLOWLY        
PREPARE TO STOP        
The system will instruct the operator to stop lifting:
Table 33
       
STOP LFT        
Steps 5.a through 5.c will be repeated ten times.
Loaded Bucket Continuous LiftIn Step 6, the loader payload system collects bucket pressures samples over the full lift in order to calculate the loaded bucket lifting calibration curve.
The operator is instructed to lower the bucket fully to the ground:

LOWER BKT FULLY        
Then the operator is instructed to tilt the bucket back fully:
Table 35
TLT BKT BACK FULLY        
THEN PRESS [OK]        
Next, the operator is instructed to lift the load. Then pull back the lift lever fully until the "STOP LIFTING" message appears. The load lift is repeated in order to ensure consistency. The process is listed here:
Table 36
PERFORM LOADED LFT        
ENGINE SPD: HI IDLE        
Maintain engine RPM at high idle. Lift the load smoothly. The operator is then instructed to pull back the lift lever fully.

ENG SPD: HI IDLE        
Stop lifting when the "STOP LIFTING" message appears.

Velocity Compensation ("5 lifts") In Step 7, the lifting velocity compensation calibration curve is calculated. The operator is instructed to perform five additional loaded lifts. The loaded lifts are performed at the following engine speeds: 1650 RPM, 1550 RPM, 1450 RPM, 1350 RPM and 1250 RPM. Again, throttle lock may be used to set the engine speed.
The operator is instructed to lower the bucket fully to the ground:

Next, the operator is instructed to lift the load. The operator is then instructed to pull the lift lever fully until the "STOP LIFTING" message appears. In order to ensure consistency, the loaded lift is repeated. The process is listed here:

PERFORM LOADED LFT        
ENGINE SPD: XXXX RPM        
Maintain the engine RPM at the specified value. lift the load smoothly. The operator is then instructed to pull back the lift lever fully.
