1-way or 2-way CIRCUIT SELECTION VALVE OPERATION

A selection valve which selects 1-way or 2-way circuit of service port has been installed on the hydraulic tank. 1.When equipment which needs a 1-way circuit will be used, position the arrow, by using the selector lever, on the axis of the selection valve to the 1-way circuit position, to reduce the back pressure. 2.When equipment which needs a 2-way circuit will be used, position the arrow on the axis of the selection valve to the 2-way circuit position.

A 1-way circuit..... A 2-way circuit..... HAMMER etc. THUMB, TILT BUCKET, AUGER, GRAPPLE etc. To avoid personal injury: A Stop the engine before removing/changing the equipment. A Release pressure in the hydraulic system before removing/changing the equipment. (See "HOW TO RELEASE PRESSURE TRAPPED IN

THE HYDRAULIC SYSTEM".) A Position the selection valve to the correct position (either 1-way or 2-way circuit selection) before mounting the equipment. A Always select the correct valve position before mounting the equipment (1-way or 2-way circuit selection) to avoid sudden movement of the equipment.

A Leaving the selection valve to 1-way circuit selection and attaching 2-way circuit equipment may cause the equipment to move (drop) suddenly due to its own weight, as the tank line remains open, even with the engine off.
