Measurement of Hydraulic Device Performance

The manual includes detailed procedures to measure hydraulic device performance. Below is a step-by-step guide:

1. Jack up the vehicle and support both axles with jack stands. Ensure the tires do not touch the ground.
2. After disconnecting the hoses between the LST pump and the LST motor, attach hoses to the flow meter as indicated by the accompanying diagram.
3. Open the loading valve of the flow meter, start the engine at idle speed, and ensure there are no leaks.
4. Increase the engine to max RPM, and with no load, measure the flow and engine RPM.
5. Gradually close the loading valve to exert the rated load pressure on the pump, then measure the flow and engine RPM.

Note: Exercise caution to avoid mistaken hose connections or travel direction to prevent damage to the flow meter, LST pump, and/or motor.

Warning: Ensure no one approaches the machine during testing for safety reasons.
