Troubleshooting Guides

• Daily/weekly: door operation, alarm, lights, emergency communication
• Monthly: brake adjustment, governor overspeed test, guide-rail lubrication, door roller inspection
• Quarterly/annual: motor brush inspection, winding-resistance checks, complete safety gear test, renewal of worn parts
• Recommended lubrication points and intervals

1. Install gauge at test port on the manifold block.
2. Run car to top floor with 125% rated load (test weights).
3. Locate the pressure relief valve (adjacent to the main flow control).
4. Turn the adjusting screw clockwise to increase pressure, counterclockwise to decrease.
5. Target pressure = (Full load pressure + 400 PSI). Example: If full load pressure is 900 PSI, set relief to 1300 PSI.
6. Cycle car 3 times, re-check.
