Hitachi ZW370-6 Lift Arm Auto Leveler Height Kickout Control
Purpose:
The lift arm height kickout control stops the lift arm as it is raising. It stops at any position – between where the lift arms are horizontal and fully raised – that has been preset by the operator.
IMPORTANT: After replacing the lift arm angle sensor, Main Controller (MC) (Main), or Main Controller (MC) (Sub), perform learning control of lift arm angle sensor (12) prior to performing work. (Refer to SECTION 4 OPERATIONAL PERFORMANCE TEST.) Operation:
1. The lift arm height kickout control position is able to be viewed on the setting screen of dual lift arm auto leveler – height kickout, which is memorized in MC (Sub) (1).
2. Adjust the lift arm height kickout control to the required level and select the height kickout ON to make this feature effective.
3. MC (Sub) (1) receives a signal from lift arm angle sensor (12).
4. MC (Sub) (1) energizes lift arm raising coil (6) of pilot valve (5) as the lift arm is raised/and the detent function is applied at the control lever. Pilot pressure oil is directed to lift arm spool (9) of multiple control valve (8) to put it into the raise position and it holds it in this state.
5. Pressurized oil from the main pump is supplied to the bottom end of lift arm cylinder (10) and the lift arm continues to rise.
6. MC (Sub) (1) determines the stopping position of the lift arm (pre-selected by the operator), and MC (Sub) (1) deenergizes lift arm lowering detent coil (7) on pilot valve (5).
7. Pilot pressure oil from loader pilot valve (5) shifts lift arm spool (9) of multiple control valve (8) to the neutral position from what was previously the raise position. Then, the lift arm stops.
