Hydraulic Rams Precautions During Use

Installation
1 Precautions when installing the ram on the machine.
a When installing and removing from the machine, suspend the ram safely.
b Suspending the ram by the piping is not only dangerous, but can also cause damage to the cylinder.
c Secure the piston rod with a band. It is very dangerous if the rod extends unexpectedly. Also, the rod can be damaged and become unusable.
2 Welding after installing the ram may result in damage.
a If electric welding is done even at a point away from the ram, there may be sparking inside the ram and it will become necessary to replace the ram with a new one.
3 When painting the machine, mask the ram.
a If paint adheres to the rod surface or to the wiper ring and the ram is operated, the wiper ring will not function properly and foreign matter and paint can easily enter the ram. This will cause damage to the seals, drastically shortening the life of the ram.
4 Install the ram only when it is clean.

Caution During Use
1 Use only under designated conditions.
a If hydraulic oil other than the designated oil is used, the seals quickly degenerate and become damaged. If the relief valve is set at a value higher than specified, it may cause ram damage and is dangerous.
b In high temperature environments (approx. 90°C and above) or low temperature environments (below -20°C), seals quickly become damaged.
Special seal materials are necessary so check to see if the ram that you are using is suitable or not.
c The number one cause of ram oil leakage is rod damage. Be careful not to damage the rod.
2 Warm up sufficiently before beginning work.
a In cold conditions the rod seals may be frozen, so if the ram is operated at maximum pressure and maximum speed, the seals will be damaged.
b There is a large amount of air in a new ram or one which has been left for a long time, so the ram will not operate smoothly. Also, if pressure is applied suddenly without bleeding the air, high temperatures will be generated due to adiabatic compression and the seals may burn.
c Before beginning work, always move the ram at full stroke with no load and expel air from the cylinder.
3 When stopping or storing, do it at a safe and fixed position.
a The installed ram cannot maintain the same position for a long period of time, because the oil inside the ram may leak and the hydraulic oil volume decreases as it cools. Stop or store the machine in a safe and fixed position.
Maintenance, Inspection Points
1 Carry out daily maintenance and inspection.
