(1) Boom priority mode (2) Swing priority mode (3) Fine control mode (4) User modeThere are four work mode switches on the left side of the monitor panel. Each work mode switch is set for different attachment speeds or for different swing speeds.Only one work mode can be selected at a time. If a new work mode is selected, the previous work mode is deactivated automatically.When you turn the engine start switch to the ON position, the previous switch setting is maintained. Select a suitable work mode for the type of work that will be performed. The selected work mode is identified by an indicator lamp to the right of each work mode switch.
Boom Priority Mode (1) - This work mode provides oil flow priority to the boom circuit. This will raise the boom quickly in applications such as loading a truck. In this type of application, the raising of the boom is a major portion of the total cycle time.
Swing Priority Mode (2) - This work mode provides oil flow priority to the swing circuit. Because the hydraulic flow from one of the two main pumps is guaranteed to the swing circuit, swing movement will be easy and consistent regardless of the other hydraulic functions that are being used.
Fine Control Mode (3) - This work mode limits the oil flow to the circuit that moves the stick inward. Normally, the oil flow to the circuit that moves the stick inward is available from both pumps. This moves the stick quickly. When the fine control mode is used, the oil flow is limited to one pump. This will slow the stick movement, which allows more control.
User Mode (4) - To select the submode, press this switch repeatedly until the desired submode is displayed in the right two positions of the liquid crystal display. This work mode has the following three submodes:
Tamping mode "U1" is suitable for simple forming of surfaces, for compacting, or for similar operations that use the bottom of the bucket. When this mode is selected, the boom raises smoothly and the boom lowers smoothly in order to avoid bumping of the boom and lifting of the machine.Note: Make sure that the machine is not in tamping mode when you travel. If the machine is in tamping mode, the travel speed will automatically be in HIGH speed mode even though LOW speed mode is selected. Therefore, the machine will not be able to make spot turns in tamping mode.
Mode "U2" provides optional hydraulic power for special attachments. The "U2" mode is set by your Caterpillar dealer only for use in special circumstances.
Customer mode "U3" allows the operator to choose the preferred modes with a single switch. The operator can set the work mode, the power mode, the pump flow, and the Automatic Engine Speed Control (AEC) according to preset settings. This mode offers the advantage of customizing these settings in order to meet the operator's specific needs.For example, the customer mode is useful during lifting
