Recommendations:
Protect the cylinder circuit with a relief valve set at 200 bar
Check the oil cleanness (pollution), and prevent it from having strange objects (place a filter on the cylinder circuit)
Bleed the circuit by slightly loosening the cylinder fittings before starting-up
Do not weld on the cylinder tube
Before welding on the rod or on the bottom, please dismount the cylinder
In case you need to store the cylinders for a long period of time, please avoid outdoor storage. If not possible, the rod must be completely retracted or it must be greased instead
For high-pressure cleaning or blasting on the cylinder, the rod and the oil-ports must be suitably protected
For double-acting cylinders working as single acting, we recommend to connect the non-used oil-port to tank
In case you need to dismount the cylinder, please note that the piston is screwed onto the rod end and fixed with industrial glue, so you must use also industrial glue when mounting again
