NOTE: DO NOT allow the RANGER 300 to run out of fuel. If it does, you will have to bleed the injec- tion system. See the Maintenance section of this manual and the Engine Operators Manual for instructions on bleeding the fuel injection system.

CAUTION

USE DIESEL FUEL ONLY

Purchase diesel fuel in quantities that will be used within 30 days, to assure freshness.

------------------------------------------------------------------------

STARTING THE ENGINE

CAUTION

Remove all loads connected to the AC power recepta- cles and the welder before starting the diesel engine.

------------------------------------------------------------------------

1.Open the engine compartment door and check that the fuel shutoff valve located above the clear plas- tic fuel filter housing is in the open position (lever in the vertical position). See Figure B.3.

FIGURE B.3

2.Check for proper level of coolant in the plastic reserve overflow tank. The level should be between the full and the low marks.

3.Check for proper oil level on the oil dipstick. Close engine compartment door.

4.Set “IDLER” switch to “AUTO”. /

5.Set the “ENGINE” switch to “ON”. Observe that both the oil pressure light and battery charger light are on. Check the fuel gauge to make sure that there is an adequate fuel level (NEVER ALLOW THE RANGER 300 D/DLX TO RUN OUT OF FUEL).

6. Press the “GLOW PLUG” button to pre-heat the cylinders per the following table:

Ambient Temperature

 

Pre-Heat Time

 

 

 

 

 

 

 

Above 50°F (10°C)

 

NOT REQUIRED

 

 

 

50°F (10°C) to 23°F(-5°C)

 

Approximately 5 seconds

 

 

 

Below 23°F (-5°C)

 

Approximately 10 seconds

 

 

 

CAUTION

Never press the Glow Plug button continuously for more than 20 seconds.

------------------------------------------------------------------------

7.Release the "GLOW PLUG" button and press the “START” button to crank the engine. Release when the engine starts.

8.Check that the indicator lights are off. If not, imme- diately stop the engine and investigate the indicat- ed problem.

9.Allow the engine to warm up at low idle speed for several minutes before applying a load and/or switching to high idle. Allow a longer warm up time in cold weather.

NOTE:If the engine fails to start in 60 seconds or stops running the “ENGINE” switch must be switched to “OFF” and then switched back to “ON” before attempting to restart the engine. This resets the engine protection circuit.

COLD WEATHER STARTING AND OPERATION.

The Kubota engine used in the Ranger 300 can be started in temperatures as low as 5°F (-15°C). At tem- peratures below 23°F (-5° C), it is recommended that No. 1D diesel fuel be used in place of No. 2D. Allow engine to warm up before applying a load or switching to HIGH idle.

STOPPING THE ENGINE

1.Remove all welding and generator power loads and let the engine cool by running it for several minutes at low idle.

2.Stop the engine by placing the Engine Switch in the OFF position. This turns off the fuel solenoid. You can also stop the engine by turning off the fuel valve located on the fuel filter housing.
