COMPONENT OPERATION ／ Control Valve ・Detent operation Lift plunger section １．When the control lever is pushed forward to set it in the "FLOAT" position, the lift spool (1) is fully pulled. At the same time the detent pin (2) installed to the spool end is moved and 4-pieces of the detent balls (3) are dropped into the groove on the detent sleeve (4). ２．As the detent balls (3) are pushed by the detent spring (5), the lift spool (1) is held in "FLOAT" position and the detent mechanism is activated. ３．When the detent operation is cancelled, pull the control lever. The detent ball (3) exits the groove and the detent operation is cancelled.

Tilt plunger section １．For the detent mechanism on the tilt spool section, an electromagnetic detent mechanism has been equipped. For the electric circuit, the current goes from the battery to the proximity switch on the auto-lever through the coil assembly (4) in the tilt section. ２．When the bucket is tilted forward from the level position, the proximity switch is closed and acts the coil assembly (4). ３．When the control lever is moved fully to the "TILT BACK" direction, the tilt spool is pressed in to the end. At the same time the pin (2) attached to the spool end is pressed in, so that the plate (3) touches the coil (4). Therefore the tilt spool (1) position is held and the detent mechanism is activated. ４．When the detent operation is cancelled, operate the control lever manually to cancel.
