I. Visual Inspection
-
Check for surface rust
-
Surface rust on the hydraulic ram may lead to reduced sealing performance. Regularly check the ram surface for rust, especially the piston rod. If rust is found, clean it promptly. Gently polish the rusted area with fine sandpaper and then apply rust preventive oil to prevent further rust spread.

-
Check connection points
-
Check if the bolts and nuts connecting the hydraulic ram to the equipment are loose. Loose connections may cause unstable ram operation or even equipment damage. Regularly tighten the connecting bolts with a wrench to ensure they are secure and reliable. Also, check for oil leaks at the connections. If oil leaks are found, the seals may be damaged and need to be replaced promptly.

II. Hydraulic Oil Check
-
Oil level check
-
The oil level in the hydraulic ram's oil tank or hydraulic system must be maintained within the appropriate range. Check the oil level before work each day to ensure it is between the upper and lower limits on the dipstick. If the oil level is too low, it may cause the hydraulic pump to suck air, affecting the normal operation of the ram; if the oil level is too high, it may cause hydraulic oil leakage. If insufficient oil is found, add the same type of hydraulic oil promptly.

Oil quality check
-
The cleanliness and quality of the hydraulic oil are crucial to the life and performance of the hydraulic ram. Regularly check the color, transparency, and smell of the hydraulic oil. If the hydraulic oil turns black, cloudy, or has an unusual smell, the oil may have deteriorated. Deteriorated hydraulic oil will increase friction in the hydraulic system, reduce lubrication, and even clog hydraulic components. It is generally recommended to change the hydraulic oil every 3-6 months. The specific replacement cycle can be determined based on the equipment's usage frequency and working environment.
