The switch for the overload warning device is located on the right console.
Overload Warning Device - In lifting applications, the overload warning device activates a buzzer when there is an unstable load condition. When this occurs, the bucket load should be reduced or the stick should be moved inward.
On - Push the right side of the switch in order to activate the overload warning device.
Off - Push the left side of the switch in order to deactivate the overload warning device. A controller is responsible for determining when an unstable load condition exists. If the preset pressure setting is exceeded in the controller, an internal buzzer is activated in order to warn the operator of the situation. The controller's setting should match one of the settings that are given in Table 1.
