Before disconnecting the hydraulic piping, place
containers of suitable size underneath to prevent
oil spillage.
CAUTION
Plug all disconnected parts to prevent dust or
impurities from entering the circuit. They can
cause serious damage.
DANGER
Before disconnecting the hydraulic piping,
ensure there is no pressure in the line. In case,
release the pressure by operating the control
levers with the engine stopped.
In any case, disconnect the hydraulic piping
with extreme caution and always wear suitable
personal protection equipment -e.g. goggles,
gloves, facial screen, etc.
Wrap up the end of the pipe to be disconnected
with some rags and slowly loosen the pipe
connector so that air comes out as slow as
possible.
