Auto Warm Up
Illustration 5 g06246518The auto warm up feature is a convenient way to make sure that the machine component temperatures are optimum for machine operation. For more settings, locate under the Settings, Machine Settings, Auto Warm Up screen.AEC
Illustration 6 g06246523When enabled, the Automatic Engine Speed Control (AEC) automatically reduces engine speed when the machine is inactive. The AEC system is designed to reduce fuel consumption and noise. Lower engine speeds can also increase engine life.The engine rpm will recover automatically to the setting of the engine speed dial when any hydraulic function is activated.Operation of AEC is affected by the manual low idle switch. See the following table for the different modes in AEC.
Table 1
AEC Mode AEC State Position of Manual Low Idle Switch Description of Mode
First stage Disabled OFF The electronic controller automatically reduces engine speed by 100 rpm after there has been no hydraulic demand for approximately 3 seconds.
Second stage Enabled OFF The AEC system in the electronic controller will automatically reduce the engine rpm to approximately 1000 rpm after there has been no hydraulic demand for approximately 3 seconds.
Manual low Idle Enabled or Disabled ON The engine speed is reduced to approximately 1000 rpm. Note: The position of the engine speed dial has no relevance on the actions described in Table 1.Heavy Lift
Illustration 7 g06246527This work mode increases the relief pressure in the hydraulic circuit, which increases the hydraulic force that is available for lifting operations. The cylinder speed is slower when this mode is selected.Note: During normal excavation work, the heavy lift control must be in the OFF position.
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.
Smart Boom
Illustration 8 g06246545The smart boom feature provides ease of use features for the operator during boom lowering and raising. For more information on the operation of this feature refer to Operation and Maintenance Manual, Smart Boom Control.Fine Swing
Illustration 9 g06246550
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.
When the fine swing control is enabled, 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.Operate the machine with the fine swing control disabled when the machine is on a slope. Operate the machine with the fine swing control enabled when great swing forces are required. For example, digging on a sidewall requires great swing force. Operate the machine with the fine swing control disabled to control the motion with the swing brake.Overload Warning
