GENERAL DESCRIPTION

The Ranger® 250 is a gasoline engine powered DC multi-process welding power source and 120 / 240 volt AC power generator. The engine drives a genera- tor that supplies three phase power for the DC weld- ing circuit and single phase power for the AC auxiliary outlets. The DC welding control system uses state of the art Chopper Technology CT R for superior welding performance. The Ranger® 250 is not recommended for pipe thawing.

DESIGN FEATURES

ENGINE OPERATION

Before Starting the Engine:

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

2.Open top engine door and 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. Close engine door.

4.See Engine Ownerʼs Manual for specific oil recom- mendations.

ADD FUEL

WARNING

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 (100mm) from the top of the filler neck to allow for fuel expansion

DO NOT FILL THE TANK TO THE POINT OF OVERFLOW.

3.Replace the fuel cap and tighten securely.

4.See Engine Ownerʼs Manual for specific fuel rec- ommendations.
