1. Check before use: Check the appearance of the hydraulic pressure gauge before use to see if it is intact and whether there is leakage.
2. Keep clean: Keep the hydraulic pressure gauge dry and clean when using it to prevent dust and impurities from entering the pressure gauge.
3. Prevent excessive force: The hydraulic pressure gauge should not be subjected to excessive external impact or extrusion to avoid damage to the movement.
4. Regular calibration: The accuracy of the hydraulic pressure gauge will decrease with the extension of the use time, and it needs to be calibrated regularly to ensure the accuracy of the measurement results.
