PROTECT THE
ENVIRONMENT
Before disconnecting the hydraulic piping, place
containers of suitable size underneath to prevent
oil spillage.
CAUTION
Carefully clean the area around the piping to be
disconnected, plug all disconnected parts with
connectors, clothes or adhesive tape to prevent
dust or impurities from entering the circuit. They
can cause serious damage.
DANGER
Before disconnecting the hydraulic piping,
ensure the line is not under pressure. Release the
pressure if necessary 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.

4mm Allen wrench for GTH 4514 EX - GTH 4017
