The rear window of the Operator Station is a secondary exit in case of an emergency.�


Control de Sentido de Desplazamiento

• Giros en redondo o de pivote

• Palancas o pedales de desplazamiento

• Tercer pedal para desplazamien to en línea recta (accesorio)

Presenter�


The B-Series Excavators offer you a choice of travel levers or travel pedals. Both, left and right, travel pedals and levers will allow you to go forward, reverse and turn. You can also spot turn or pivot turn, as well. A third pedal for straight travel is available as an attachment--and equipped only on certain machines. This pedal will move the excavator in a straight line. �

A quick change valve quickly switches between patterns. If the machine is equipped with an optional quick change valve, the proper control pattern must be displayed on an information card in the cab. It is good practice to verify the control pattern with the information card in the cab.�


Palanca de Activación Hidráulica

• La posición Trabada (hacia abajo) desactiva todos los controles hidráulicos

• La posición Destrabada (hacia arriba) activa todos los controles hidráulicos

Presenter�


The hydraulic activation control lever in the LOCKED position makes all factory-installed hydraulic controls inoperable. The engine will not start unless the hydraulic activation control lever is in the locked position. �

de rotación y de pluma.Para ofrecer una operación mas simple, los interruptores de modalidad de potencia y de modalidad de trabajo han sido eliminados. En cambio, la función automática de prioridad de rotación y de pluma selecciona la mejor modalidad en función del movimiento de la palanca universal simplificando así la operación y optimizando el rendimiento en diferentes aplicaciones.


FUNCIONES DEL MONITORControlador de accesorios.

Los cinco ajustes de presión y de flujos de la bomba hidráulica se pueden preajustar en el monitor evitando así tener que ajustar el sistema hidráulico cada vez que se cambia una herramienta y proporcionado al operador la cantidad correcta de flujo y de presión para cada herramienta de forma instantánea. Esta característica esta disponible con el sistema de control de herramientas optativo.

Presenter�


The Electronic Monitor Panel consists of indicators and switches. The indicators are gauges for various machines systems. And the switches are for selecting the various work modes and the power modes. Included on the Electronic Monitor Panel is an action alarm, action light, gauges and alert indicators to let you know when the machine is in trouble. The monitor panel is designed to alert you of an immediate problem or of an impending problem. The panel has individual alert indicators for each machine system that is listed on the monitor panel. The problem could be in more than one of the machine systems that are listed.�

• Modalidad de apisonamiento• Modalidad de martillo• Modalidad del cliente

Presenter�


The Work Mode selector allows the choice of four modes. They are the Boom Priority Mode, Swing Priority Mode, Fine Control Mode and the User Mode. The User Mode has three submodes which allows you to customize the machine for specific jobs. The four work mode switches are on the left side of the monitor panel. Each work mode switch is set for different boom speeds or for different swing speeds. Only one work mode can be selected at at time. If a new work mode is selected, the previous work mode is deactivated automatically. �

Presenter�


The Fine Control Mode uses 70% of available engine power for lower sound levels, precise implement movement and reduced fuel consumption. 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. This work mode is used most often when you finish a slope. This work mode is also used for lifting applications or for fine grading.�

Control Automático del Motor

• Reduce la velocidad del motor si no hay actividad en 3 segundos

• Reduce el consumo de combustible

• Reduce los niveles de ruido

• Opera en 3 modalidades

Presenter�


The Automatic Engine Control automatically reduces engine speed when there is no hydraulic demand or when the hydraulic demand is very small. The AEC is also designed to reduce fuel consumption and noise. It is important to note that the AEC system will be inoperable while the backup switch of the electronic controller system is in the MAN or manual position. If the hydraulic oil is not at a normal operating temperature, the AEC may respond slowly.�


Control Automático del Motor• Modalidad 1= Interruptor AEC

desconectado– Reduce las rpm del motor

100 rpm• Modalidad 2= Interruptor AEC

conectado– Reduce las rpm – del motor a 1300

Presenter�


The AEC system will operate in 3 modes. In Mode 1, the electronic controller automatically reduces engine speed by 100 rpm after there has been no hydraulic demand for approximately three seconds. In Mode 2, the AEC system will automatically reduce the engine rpm to approximately 1300 rpm after there has been no hydraulic demand for approximately three seconds. And in Mode 3, whenever the switch for One-Touch Low Idle is activated, the engine speed is reduced to approximately 1100 rpm. Pressing the switch again will allow the engine speed to return to the setting of the engine speed dial. �


Botón de Baja en Vacío

•Situado en el extremo superior de la palanca universal derecha

•Reduce la velocidad del motor a 1100 rpm

•Funciona en ambas modalidades

Presenter�


In Mode 3, whenever the switch for One-Touch Low Idle is activated, the engine speed is reduced to approximately 1100 rpm. Pressing the switch again will allow the engine speed to return to the setting of the engine speed dial. �


Velocidad de Desplazamiento

• Usar baja velocidad para terreno difícil y alta velocidad para terreno llano

• Velocidad alta continua = 2 horas

• Parar cada 2 horas para dejar enfriar los motores de impulsión

Presenter�


When turning on the engine start switch, the travel speed control is always set at the Low Travel Speed position. Whenever the travel speed control switch is pressed, the travel speed changes. If any other hydraulic circuit is actuated while the machine is traveling in High Speed, the excavator will automatically decrease the travel speed to Low. Continuous travel at High Speed should be limited to two hours. If you need to continue traveling at High Speed for more than two hours, stop the machine for ten minutes before restarting.�


Interruptor de Cancelar Alarma• Apaga la alarma de

desplazamiento• Se usa al desplazarse

distancias largas o en lugares seguros

• Se rearma cuando se detiene la máquina

[ Explain how the monitoring system does self-test. ] During self-test, hold key in the “on” position for 2 seconds, all alert indicators flash and the digital display window shows the following readouts: - all indicators are lit - key in “on” position for 2 seconds - action light stays illuminated - action alarm sounds once for 1 second - all this happens in 1.5 seconds �

The Pre-Start Monitoring System allows you to check coolant, hydraulic oil and engine oil levels from the monitor inside the cab. However, the pre-start monitoring system does not cover all daily maintenance items. I recommend that you check these levels manually. Also keep in mind that the monitor indicator does not guarantee that the machine is in a good condition. Do not use the monitor panel as the only method of inspection.�
