WRENCH 0003565 - Caterpillar

Parking Brake (6) - The alert indicator will light when the parking brake is engaged. The alert indicator should come on when the engine start key is in the ON position and the engine is not running. The alert indicator should go out when the parking brake is released.
Electrical System (7) - The alert indicator will light when there is a malfunction in the electrical system. If this alert indicator comes on, the system voltage is too high for normal machine operation or too low for normal machine operation. If electrical loads (air conditioning and/or lighting) are high and the engine speed is near idle, increase the engine speed to high idle. This will generate more output from the alternator. If the alert indicator for the electrical system turns off within one minute, the electrical system is probably operating in a normal manner. However, the electrical system may be overloaded during periods of low engine speeds.Modify the operating cycle in order to prevent overloading the electrical system and discharging the batteries.Low idle must be set correctly. Adjust for the high side of the Low Idle specification while the most often used electrical loads are turned on. In order to reduce the loads, use the Medium fan speed instead of the High fan speed.If this procedure does not cause the alert indicator to turn off, move to a convenient location. Investigate the cause (loose alternator belt, broken alternator belt, faulty batteries, etc).If the engine speed is near operating speeds and if the electrical loads are light, the alert indicator may remain on. If the alert indicator remains on, move to a convenient location. Investigate the cause (loose alternator belt, broken alternator belt, faulty batteries, etc).
Air Inlet Heater (8) - If the engine coolant temperature is too low, the air inlet heater will be activated. This indicator will illuminate when the start switch is in the ON position. Start the engine after the indicator light goes off.
Water in the Fuel System (9) - This indicator light will come on when the fuel system water separator needs to be drained. This indicator will go out after the water has been drained from the water separator element for the fuel system. Refer to Operation and Maintenance Manual, "Fuel System Water Separator - Drain" for the correct procedure.
Restricted Air Filter (10) - This indicator light will come on when the air filter is restricted. If the air filter is restricted, then engine output will be decreased. Immediately inspect the air filter. Clean the air filter. Inspect the condition of the air filter. Replace the air filter, if necessary. Perform any necessary repairs. Note: Manually reset the air filter switch after cleaning the air filter.Reference: Operation and Maintenance Manual, "Engine Air Filter Primary Element - Clean/Replace"Reference: Operation and Maintenance Manual, "Engine Air Filter Secondary Element - Replace"Gauges
