FUEL LEVEL DG250MI is equipped with monitoring function for water/coolant temperature, oil pressure, battery charge, air filter flow, battery fluid level, and fuel level. DG150MI is equipped with monitoring function for water/coolant temperature, oil pressure and battery charge. When the equipment is started under normal condition, Oil Pressure and Battery Charge lamps will flash when the Starter Switch is turned from STOP to OPERATING, and all lamps will go off, immediately after the engine is started. - Page 10 When the water temperature reaches 110 degrees Celsius during operation, the water temperature-monitoring lamp will flash, and the automatic shutoff will be engaged. When this occurs, check the Coolant reservoir tank, and replenish if needed (refer to 8-2 Checking coolant / water level). If the water level is normal, check for loose fan belt or possible water leak in the cooling system, after the engine is cooled down.
- Page 11 5.1.3 Battery Charge Monitoring Lamp (charge lamp) When the battery is unable to be charged during operation, the battery charge-monitoring lamp will flash. Check the belt for damages or cut, and replace if needed. <Caution> For changing the belt, refer to the User Manual for Engine. Battery Charge Monitor cannot detect the degradation of battery life nor the battery fluid level (refer to 8-6 Checking Battery) 5.1.4 Air Filter Monitoring Lamp (clogged filter element) [DG250MI only]...

When the battery fluid level is low, Battery Fluid Monitoring Lamp will flash. If the lamp is flashing, quickly add some distilled water. (refer to 8.6 Checking Battery) 5.1.6 Fluid Level Monitoring Lamp [DG250MI only] Caution : Fire This equipment uses Diesel fuel as a fuel. When refueling, always stop the engine, and keep away from fire. - Page 13 5.2.3 Water Temperature Gauge [DG250MI only] Water Temperature Gauge displays the temperature of engine coolant. Normal temperature may vary depending on the environment, but it should be between 75 to 90 degree Celsius. <Caution> If the temperature exceeds normal value, disconnect the load, idle the engine at 1000min , and wait until the reading falls to the normal temperature range.
