RECOMMANDATIONS
- Protection of the circuit by a relief valve and a filter
- Check the oil cleanness (pollution)
- To bleed the air from the cylinder and the hydraulic
circuit
Welding: do not weld on the tube. Dismount
the cylinder to weld on the rod or on the base
Storing: storage of extended cylinder, the
rod must be greased. For high pressure cleaning, protect the
rod.In any case should the cylinder be used as a mechanical
limit stop for moving loads. For double acting cylinders working
as single acting, it is essential to connect the unused port
to the tank
