DISCONNECTION
1. Make sure to stop the engine be-
fore disconnecting it.
2.
Release any residual pressure in the
hydraulic hoses of the implement
and tractor by operating the double
acting valve lever 4 to 5 times.
3. Remove any foreign material
around the couplers.
4. Lower the implement on the ground
or remove any external load applied
to the implement. Disconnecting
hoses while outer load is applied to
the implement is very difficult and
dangerous due to the pressurized
uid in the hose.
5. Remove the male coupler by push-
ing the female coupler boss back-
ward.
6. Close the dust-proof cover of the
female coupler. Wrap the male cou-
pler of the implement with a plastic
bag to prevent contamination.
WARNING
•
Never connect or disconnect the
implement hydraulic hoses while
the pressure in it is not released
or the engine is running. It is hard
to connect and disconnect the
hose and hydraulic uid can be
sprayed from the hose, and get
into your eyes or skin.
•
Stop the engine and wear pro-
tective glasses and gloves
before work.
