Illustration 10 g03382770Diverter valves are used to divert oil from the bucket cylinder to the auxiliary lines. These valves (A) are attached on the left and right side of the boom. The bucket auxiliary circuit is open when the left ball valve handle has been turned counter-clockwise as far as it will go and the right ball valve handle has been turned clockwise as far as it will go. The bucket auxiliary circuit is closed when the left ball valve handle has been turned clockwise as far as it will go and the right ball valve handle has been turned counter-clockwise as far as it will go.The line (5) that is located on the right side of the stick is for oil feed/return. The line (6) that is located on the left side of the stick is used as an oil feed/return line.The bucket auxiliary circuit lines are equipped with coupler assemblies. Wipe all coupler assemblies before you connect the work tools.The bucket auxiliary circuit lines must be relieved of pressure in order to connect the coupler assemblies to the work tool. Relieve the pressure in the auxiliary hydraulic lines by performing the following steps:
Turn the engine start switch key to the OFF position.
Move the control levers in all directions repeatedly.
Uncouple the work tool immediately after the pressure has been released. Note: Pressure can build up in the bucket circuit auxiliary lines if the work tool is not uncoupled immediately after the pressure has been released.Auxiliary Control Pedal (AUX 1) (Two-Way Flow)
Unintended operation of the Auxiliary Control pedal can cause injury or death. A RAISED hydraulic lock lever does not mean that the auxiliary line is locked out.To Prevent unintended activation of the Auxiliary Control pedal while traveling or whenever the auxiliary line is not being used, make sure the foot is not placed on or near the Auxiliary Control pedal.
Note: Operate the Auxiliary Control pedal carefully until you become familiar with how AUX 1 reacts to the controls.The right Auxiliary Control pedal controls the two-way flow auxiliary line circuit (AUX 1).
