If this machine is used to lift objects within an area that is controlled by the European Directive "2006/42/EC", the machine must be equipped with a boom lowering control valve, a stick lowering control valve, and an overload warning device.
If equipped, 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 the buzzer sounds, 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.Fine Swing Control (24)
The Fine Swing Control delays the engagement of the swing parking brake.If the machine is operating on a slope with the Fine Swing Control in the ON position, the swing motion may become uncontrollable which could result in property damage, personal injury or death.Turn the Fine Swing Control to the OFF position when the machine is operating on a slope.
Fine Swing Control - If equipped, push down on the top of the switch in order to activate the fine swing control.When the fine swing control is ON, the swing parking brake is released. Swing control improves during deceleration of a swing because the swing is allowed to drift instead of stopping abruptly.Push down on the bottom of the switch in order to turn off the fine swing control. Operate the machine with the fine swing control in the OFF position when the machine is on a slope. Operate the machine with the fine swing control in the OFF position when great swing forces are required. For example, digging on a sidewall requires great swing
