Würth 1952 008 114 Traducción Del Manual De Instrucciones De Servicio Original página 35

- For piston return, unscrew anti-clockwise the pusher up to
complete withdrawal of the former.
- Remove the mechadraulic cylinder from its position only after
verifying that each component is not stressed by its thrust.
Notes: Do not allow piston rotation during its
thrust. Piston rotation could damage internal
seals above all the return spring.
DANGER
- Never release the internal hydraulic pressure by loosening
the handle!
- Never release the internal hydraulic pressure by loosening
the air release screw!
- Never screw clockwise the pusher in case of grease
leakage from the handle.
MAINTENANCE
WÜRTH mechadraulic cylinders do not require any particular
maintenance; however, users should consider the following aspects
to increase their service life:
• In case of replacement or topping up, always use grease
compliant with the characteristics indicated in table A;
• Cylinders should be kept in dry and not dusty places to increase
their service life in case they are not used;
• Store cylinders with the rod completely set back to avoid
external chemical agent attacks which might damage
smoothness and seal;
• Before and after any use, always check if grease leakage
occurs;
• If internal rings are replaced, the cylinder should be repaired
only by qualified and experienced personnel.
Cylinder bleeding (fig. 2)
- Place the cylinder so that the piston goes downwards and the
handle is lower than the air release screw.
Screw the screw pusher and slightly loosen the air release; screw
tight the air release screw as soon as grease starts coming out.
- Always keep clean the pusher screw to avoid traces of metal
particles.
- Operation should be flowing and fluid, therefore verify that the
screw thread has not been damaged.
STORAGE
Protect cylinders from water if storage is in the open air.
