Engine Oil Low Pressure Indicator and

Alarm (Figure 14) - When the engine oil pressure falls below normal, the oil pressure sensor will send a signal to the indicator, causing it to light and the alarm to sound. Stop operation immediately to avoid damage to the engine. Check the oil level and troubleshoot the lubrication system.

Figure 13

Coolant High Temperature Indicator and

Alarm (Figure 13) - When coolant temperature reaches the maximum allowable temperature (95°C [203°F] or higher), the indicator will light and the alarm will sound. Continuing operation at temperatures exceeding the maximum limit will result in damage and seizure.

Check the load and troubleshoot the cooling system.
