This section contains basic operating procedures for the foam fire suppression system. The foam fire suppression system may be activated automatically or manually. The foam fire suppression system may also include an engine shutdown control.

ReferenceFor more complete information, refer to the fire suppression system manufacturer's information.

Fire Suppression Control (Manual)

Show/hide table

Manual actuation of the fire suppression system will result in immediate system discharge which may obscure vision and affect the operator's ability to control the machine. This may result in personal injury or death. Make certain the machine is stopped safely before manually actuating the system. Manual actuation will bypass all auxiliary shutdown and alarm functions.

There are two manual actuators on the machine.

Manual actuator (1) is located in the operator's station of the machine. Manual actuator (3) is located on the right side of the engine hood.

Activate the fire suppression system by turning handle (2) or (4) counterclockwise.

Fire Suppression Control (Engine Shutdown)

Engine shutdown control for fire suppression and idle timer

The function of the fire suppression control is to cause a delayed engine shut down when the fire suppression system is activated.

Fire System Activated (1) - This indicates that the fire suppression system has been activated. When this indicator flashes, an alarm will sound and the engine will shutdown after a six second delay.

Engine Shutdown Switch (2) - This switch allows the engine to be shutdown immediately. Push and hold engine shutdown switch (2) down to shutdown the engine.

Note: During normal operation use the engine start switch to shutdown the engine.

System Reset Button (3) - This button is used to override the fire suppression control so that the machine can be moved after discharge of the fire suppression system and loss of system pressure.

The "SYSTEM RESET" button must be held in for the engine to operate. Upon release, the engine will shutdown after six seconds.

Note: The override function should only be used in an extreme emergency. Restarting the machine before the fire suppression system has been recharged can reignite the fire that had been previously suppressed, without a means of extinguishment.

Idle Timer Function

Certain machines may be equipped with an idle timer control (engine shutdown) in addition to the fire suppression control.

Idle Timer On Indicator (4) - Indicates that the idle timer has been activated. When the engine start switch is turned to the OFF position, the indicator will flash and the engine will stop after three minutes.

Note: The idle timer will activate whenever the engine start switch is turned from the ON position to the OFF position.

To override the idle timer and stop the engine, turn the engine start switch to the OFF position and push the engine shutdown switch down.

Note: If the idle timer has been activated without starting the engine, it can be deactivated by pushing engine shutdown switch (2) down. Indicator (1) should stop flashing.

NOTICE
Never turn the battery disconnect switch to the OFF position with the idle timer activated (engine running). Electrical system damage could result.

In Case of Fire

Show/hide table

In case of fire, evacuate the area to reduce the risk of injury from flames, heat, hazardous vapors, explosions, or any other hazards that may be created.

The following procedure should be read and performed in accordance with the current mine site practices.

In case of fire perform the following procedure:

1. When a fire is detected or when the system alarm (if equipped) sounds, bring the machine to a safe controlled stop.

2. Stop the engine.

3. Engage the parking brake.

4. If not automatically activated, manually activate the fire suppression system by turning the handle on the manual fire suppression control counterclockwise.

5. Evacuate the machine.

6. If possible, turn the battery disconnect switch to the OFF position.

7. Notify the appropriate mine personnel.

8. Stand by (at a safe distance) with a portable fire extinguisher.

Note: Stand by with a portable fire extinguisher to guard against any fire that may reignite after the fire suppression system has discharged. Remain alert until the possibility of reignition is past.

NOTICE
If the fire suppression system has been activated, the system must be flushed and recharged. Have the machine cleaned, inspected and repaired before returning the machine to operation.
