Connecting and Disconnecting Implement
Connection
1) Make sure to stop the engine before connecting it.
2) Move the double acting valve lever forward and backward for 4 to 5 times to release the pressure in the
hydraulic line of the tractor. Otherwise, it is hard to connect the couplers, and hydraulic fluid can be sprayed
from the line and get in to your eyes while connecting them.
3) Remove any foreign material around the male and female couplers. If foreign material enters the hydraulic
components, it can lead to malfunction of the system.
4) Open the dust-proof cover of the female coupler of the tractor and insert the male coupler of the
implement. A clicking sound is heard when the couplers are engaged.
5) Pull the hydraulic hose of the implement to check that the couplers are properly connected.
6) Start the engine and check the operating status and leakage.
Disconnection
1) Make sure to stop the engine before 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) Keep the implement balanced by removing any load applied (lowering it onto the ground, for example). If
disconnecting the hose while outer load is applied to the implement, it is hard to connect the implement in the
future.
5) Remove the male coupler by pushing the female coupler boss of the tractor backward.
6) Close the dust-proof cover of the female coupler of the tractor. Wrap the male coupler of the implement
with a plastic bag to prevent contamination.
Warning:
- Never connect or disconnect the implement hydraulic hose while the pressure in it is not released
or the engine is running. It is hard to connect and disconnect the hose and hydraulic fluid can be
sprayed from the hose, and get into your eyes or skin.
- Stop the engine and wear protective glasses and gloves before work.
