RECOMMENDATIONS | |
Protect the circuit with a 200 bar pressure limiter | |
Check the purity of the fluid, avoiding the presence of foreign bodies | |
Install a filter on the hydraulic cylinder circuit | |
Bleed the circuit by slightly unscrewing the supply connections before commissioning | |
Do not weld on the tube | |
Dismantle the cylinder to weld on the rod or base | |
If hydraulic cylinders are to be stored for long periods, avoid storing them outdoors, | |
The rod fully retracted into the tube and greased | |
For high-pressure cleaning or sandblasting, the stem and oil inlets must be protected | |
For double-acting cylinders working in single-acting mode, it is strongly recommended to connect | |
The unused port on the tank | |
If the cylinder is dismantled, note that the piston is screwed onto the end of the rod and | |
Fixed with industrial adhesive, so be sure to glue it in place when reassembling. |
