6. Техникалык тейлөө
6.1 Сенсорду тазалоо
If the vacuum gauge sensor becomes contaminated with oil, it may display no value or inaccurate readings. In such cases, it is necessary to clean the vacuum sensor.
Video 2: Illustrates the importance of cleaning the vacuum sensor if it becomes contaminated with oil, as contamination can prevent accurate readings. The video shows how to access and clean the sensor using a solvent.
- Disconnect the gauge from the system.
- Carefully remove the 1/4" SAE fitting to expose the sensor.
- Use a suitable solvent (e.g., isopropyl alcohol) and a lint-free cloth or cotton swab to gently clean the sensor surface.
- Allow the sensor to dry completely before reassembling.
- Replace the O-ring, filter net, and filter cotton as needed to ensure proper sealing and filtration.
6.2 Жалпы кам көрүү
- Store the gauge in its protective zip bag when not in use.
- Avoid dropping or subjecting the gauge to strong impacts.
