Product Recommendations

– Protection of the circuit by a relief valve and a filter
– Check the oil cleanness (pollution)
– Bleed the air from the cylinder and the hydraulic circuit

The cylinder should not, under any circumstances, be used as a mechanical limit stop for moving loads.
Single-acting cylinders must be fitted with a tank return for unused power.

• 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.
The cylinder cannot be used to hold any loads. Mechanical locks must be used.
For double acting cylinders working as single acting, it is essential to connect the unused port to the tank

• Striping down: Warning : the piston is locked with glue (glue it again when re-assembling)
