1.Remove the fuel tank cap.

2.Fill the tank approximately 4 inches (100mm) from the top of the filler neck to allow for fuel expansion. (Observe the fuel gauge while filling.) DO NOT FILL THE TANK TO THE POINT OF OVERFLOW.

3.Replace the fuel cap and tighten securely.

4.See the Maintenance section for specific fuel rec- ommendations.

STARTING THE ENGINE

1.Remove all plugs connected to the AC power receptacles.

2. Set the IDLER switch to AUTO. /

3.Set the RUN/STOP switch to RUN.

4.Pull the choke to the full out position.

5.Press and hold the engine START button until the engine starts.

6.Release the engine START button when the engine starts.

7.Push the choke back in.

8.The engine will run at high idle speed for approx- imately 12 seconds and then go to low idle speed. Allow the engine to warm up at low idle for sever- al minutes before applying a load and/or switch- ing to high idle. Allow a longer warm up time in cold weather.

CAUTION

Operating the starter motor for more than 5 seconds can damage the motor. If the engine fails to start, release the START button and wait 10 seconds before activating the starter again. Do NOT push the START button while the engine is running because this can damage the ring gear and/or the starter motor.

NOTE: Starting a Ranger 250 for the first time, or after an extended period of time of not operating, will take longer than normal. The fuel pump has to fill the fuel line and carburetor. If the engine will not start, see the Troubleshooting section of this manual.

STOPPING THE ENGINE

1.Remove all welding and auxiliary power loads and allow the engine to run at low idle speed for a few minutes to cool the engine.

2.Stop the engine by placing the RUN-STOP switch in the STOP position.

NOTE: A fuel shut off valve is not required on the Ranger 250 because the fuel tank is mounted below the engine.

BREAK-IN PERIOD

Any engine will use a small amount of oil during its “break-in” period. For the gasoline engine on the Ranger 250, break-in is about 50 running hours.

Check the oil at least twice a day during break-in. Change the oil after the first 25 hours of operation. Change the oil filter at the second oil change. For more details, see the Maintenance section of this manual.

CAUTION

During break-in, subject the Ranger 250 to moderate loads. Avoid long periods running at idle. Before stop- ping the engine, remove all loads and allow the engine to cool several minutes.
