HOLD
When the implement is fully moved up, the control valve is placed in neutral position while the
implement is moving up or down. The implement can be held in any desired position.
FLOW CONTROL VALVE
The flow control knob which controls the lowering speed of the implement is located in front of the
hydraulic case under the seat. When the knob is turned clockwise, the lowering slows down, and when
further turned, the control valve is closed. As a result, the implement will be held in it’s position and not
move downward any more. Turning the knob counter-clockwise makes the lowering speed faster.
INSTALLING THE EXTERNAL HYDRAULIC ADAPTER (OPTIONAL)
When the hydraulic adapter is used:
Loosen the three bolts on the left side of the hydraulic case, and remove the cap taking care to not drop
the O-ring.
Fit the O-ring correctly to the hydraulic adaptor and install it on the hydraulic case. Tightening torque
2.5 ~3.0 kg-m (18~22 ft-Lb).
Connect the outlet of the external hydraulic adaptor, inlet of the control valve attached to the
implement mounted on the tractor, outlet of the control valve, and oil return port of the external
hydraulic adaptor by pipes.
Start the engine and by operating the control valve of the implement mounted on the tractor bleed the
cyclinder and pipes. Then check the pipe joints for oil leakage.
NOTE: To use the external hydraulic adaptor the implement mounted on the tractor must have a double
action control valve.
EXTERNAL HYDRAULIC Service
When the tractors hydraulic valve is used:
The control valve equipped on the tractor is of single action type, and therefore the implement mounted
on the tractor must be also of a single action type.
Connect the hydraulic external service plug and cylinder plug of the implement with a rubber hose.
Relieve the auto-return of the hydraulic control lever moving the locknuts backwards on the auto –
return rod. Start the engine and place the control lever in the lift position. By operating the safety valve
bleed the air completely from the cylinder and pipes, and lock the flow control knob. When the
hydraulic control lever is placed in “Lift”, the implement moves upward, when placed in the “Down” the
implement moved downward.
