ADVICE TO RENEW FLEXIBLE HOSES
PROTECT THE
ENVIRONMENT
Before disconnecting a hydraulic pipe, 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 pipe, check that
there is no residual pressure. In case, eliminate the
pressure operating the control levers with the engine
stopped. In any case, disconnect the hydraulic pipe
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.
