Monitor Switches Portion

Use this switch (1) to set the movement or power of the work equipment.

The operation becomes easier if the mode is selected to match the content of the operation.

P mode: For heavy-load operations

E mode: For operation with emphasis on fuel consumption L mode: For fine control operations

B mode: For breaker operations

ATT mode: For double-acting circuit attachment, such as crusher (attachment-ready machines)

When the monitor first appears, it is automatically set to the mode in use when it was started the previous time.

Press switch (1) to display the working mode selection screen.

For each set mode, the pilot monitor at the top right of the monitor display shows P, E, L, B, ATT.

OPERATION

For machines ready for attachment, the attachment mode is added to the display.

For details of the method for handling machines ready for attachment, see the ATTACHMENTS AND OPTIONS Section.

When the monitor starts up, if the working mode setting is B mode, the confirmation message on the right is displayed and the buzzer sounds.

When starting up and staying in B mode, always press function switch F6 (Yes).

If you press F5 (No), the system starts up in E mode.

If you want to have automatic setting of the P, E, L, B or ATT mode when starting (optional default setting), please ask your Komatsu distributor to change the setting.

Procedure for operation

1. If working mode selector switch (1) is pressed, the Working Mode screen is displayed on the monitor.

2. Press function switches F3 or F4 at the bottom of the screen or working mode selector switch (1) to change the mode selection one at a time.

If no switch is touched for more than five seconds, the selected working mode is automatically set as the working mode and the screen changes to Steps 3 and Steps 4.

REMARK

OPERATION

OPERATION

REMARK

When setting the working mode to B mode, to ensure safety, the buzzer sounds and at the same time, the message in the illustration on the right is displayed. When setting to the breaker mode, always press function switch F6.

If function switch F5 is pressed, the breaker mode is not set, and the screen returns to working mode selection screen.

NOTICE

When using the breaker, set to B mode. If B mode is not used, there is danger that the breaker may break.

Auto-deceleration Switch

If the control levers are at neutral, this switch (2) automatically lowers the engine speed and turns on the function to reduce fuel consumption.

Auto-deceleration monitor ON: Auto-acceleration ON Auto-deceleration monitor OFF: Auto-acceleration OFF

Each time the switch is pressed, the auto-deceleration is switched between actuated and canceled.

Auto-deceleration function

When the auto-deceleration function is ON, if the work equipment and travel levers are returned to the N position, the engine speed will drop after 4 seconds from the operating speed to idling speed.

This makes it possible to reduce fuel consumption.

If any lever is operated when the machine is in this condition, engine speed will return to the previous operating speed to make it possible to perform operations.

1. When auto-deceleration switch (2) is pressed and the auto-deceleration function is turned ON, the mode is displayed in the center of the monitor display, and after two seconds, the screen returns to the standard screen.

2. On the standard screen, the Auto-deceleration monitor lights up.

(When the auto-deceleration is OFF, it does not light up.)

OPERATION

Travel Speed Selector Switch

WARNING

When loading or unloading from a trailer, always travel at low speed (with travel speed selector switch (3) at the Lo position).

Never operate travel speed selector switch (3) while loading or unloading.

If the travel speed is switched between Hi and Lo when the machine is traveling, the machine may deviate to one side, even when traveling in a straight line.

Stop the machine before switching the travel speed.

Switch (3) is used to set the travel speed to 3 stages.

Lo lights up : Low-speed travel Mi lights up : Medium-speed travel Hi lights up : Hi-speed travel

When the engine is started, the speed is automatically set to Lo.

Each time that the switch is pressed, the display changes Lo J Mi J Hi J Lo in turn.

Even if the travel speed is set to high-speed (Hi) or a mid-range speed (Mi), when traveling on soft ground or uphill, and travel power is needed, the system automatically shifts down to low speed travel (Lo). There is no need to operate the switch. In this case, the pilot monitor on the monitor display stays lighted up at Hi (high-speed) or Mi (mid-range speed).

REMARK

Each time travel speed selector switch (3) is switched, the mode is displayed on the monitor display, and after two seconds, the screen returns to the standard screen.

Wiper Switch

Switch (4) operates the wiper for the front glass.

Each time the switch is pressed, it changes ON → INT → stop (OFF).

Wiper monitor INT lighted up: Wiper operates intermittently Wiper monitor ON lighted up: Wiper operates continuously Wiper monitor OFF: Wiper stops

REMARK

Each time wiper switch (4) is pressed, the mode is displayed in the center of the monitor display, and after two seconds, the screen returns to the standard screen.

OPERATION

Window Washer Switch

Switch (5) is kept continuously pressed, window washer fluid is sprayed onto the front glass. When the switch is released, spray stops.

If switch (5) is kept pressed when the wiper is stopped, the window washer fluid will spray, and at the same time, the wiper will be actuated continuously. When switch (5) is released, the wiper will continue to operate for 2 cycles, then stop.

If the wiper is moving intermittenly and switch (5) is kept pressed continuously, window washer fluid will spray, and at the same time, the wiper will be actuated continuously. When switch (5) is released, the wiper will continue to operate for 2 cycles, then return to intermittent operation.

Buzzer Cancel Switch

When this switch (6) is pressed, the warning buzzer for the abnormal warning item stops.

Function Switches

Function switches (7) consist of 6 switches (F1 to F6). The function of each switch differs according to the content of each screen.

When the monitor display shows the standard screen, the functions are displayed as follows.

F3: Camera screen selector switch (if equipped) F4: Service meter/time display selector switch F5: Maintenance mode switch

F6: User mode switch

F1 and F2 are auxiliary switches for expanded functions.

For explanation of each switch, see "Handling Function Switches (PAGE 3-35)".

Air Conditioner Switch

The air conditioner switches (8) consist of 9 switches.

For explanation of each switch, see "AIR CONDITIONER CONTROLS (PAGE 3-89)".
