ENGINE OPERATION

WARNING

DO NOT RUN THE ENGINE AT EXCESSIVE SPEEDS. The maximum allowable high idle speed for the Ranger 275 is 3750 RPM, no load. Do NOT adjust the governor screw on the engine. Severe per- sonal injury and damage to the machine can result if it is operated at speeds above the maximum rated speed.

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

Read and understand all safety instructions included in the Engine Owner’s manual that is shipped with your Ranger 275.

BEFORE STARTING THE ENGINE

Check the engine oil level:

1.Be sure the machine is on a level surface.

2.Remove the engine oil dipstick and wipe it with a clean cloth. Reinsert the dipstick and check the level on the dipstick.

3.Add oil (if necessary) to bring the level up to the full mark. Do not overfill.

4.See Engine Owner’s Manual for specific oil recom-

mendations.

WARNING

Check and fill the engine fuel tank:

GASOLINE can cause fire or explosion.

•Stop engine when fueling.

•Do not smoke when fueling.

•Do not overfill tank.

•Avoid contact with skin or breathing of vapor.

•Keep sparks and flame away from tank.

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

1. Remove the fuel tank cap.

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

3.Replace the fuel tank cap and tighten securely.

4.See Engine Owner’s Manual for fuel recommenda- tions.

STARTING THE ENGINE

CAUTION

Be sure all Pre-Operation Maintenance has been per- formed. See the INSTALLATION section.

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

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

To start the engine, set the “IDLER” switch in the

“AUTO” (

/

) position. Pull the choke

control out.

 

 

Place the “Engine” Switch in the “RUN” Position. Push the “Start” button and crank the engine until it starts. Release the button as soon as the engine starts. After the engine has started, slowly return the choke control to the full “in” position (choke open). In the “AUTO” position, the engine will run at high idle for 10-14 seconds and then go to low idle. Allow the engine to warm up by letting it run at low idle for a few minutes.

At cold temperatures, it may be necessary to start the engine in “HIGH” idle and allow it to run for several minutes before using “AUTO” idle.

When starting a hot engine, it is not necessary to pull the choke out but the engine will start faster if it is pulled out. Push it in immediately after the engine starts.

CAUTION

Operating the starter motor for more than 5 seconds can damage the motor. If the engine fails to start, release the switch and wait 10 seconds before operat- ing the starter again. Do not push the “Start” button while the engine is running because this can damage the ring gear and/or starter motor.

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

NOTE: When starting a Ranger 275 for the first time, after an extended period of not operating, it will take longer than normal because the fuel pump has to fill the fuel line and carburetor.
