HIGH ALTITUDE OPERATION

At higher altitudes, output de-rating may be necessary. For maximum rating, de-rate the welder output 3.5% for every 1000 ft. (305m). Contact an authorized engine service shop for modifications to operate above 5,000 ft. (1525m).

HIGH TEMPERATURE OPERATION

At temperatures above 30°C, output de-rating is nec- essary. For maximum output ratings, de-rate the welder output 5% for every 10°C above 30°C.

TOWING

The recommended trailer for use with this equipment for road, in-plant and yard towing by a vehicle1 is Lincoln’s K957-1. If the user adapts a non-Lincoln trail- er, he must assume responsibility that the method of attachment and usage does not result in a safety haz- ard nor damage the welding equipment. Some of the factors to be considered are as follows:

1.Design capacity of trailer vs. weight of Lincoln equipment and likely additional attachments.

2.Proper support of, and attachment to, the base of the welding equipment so there will be no undue stress to the framework.

3.Proper placement of the equipment on the trailer to insure stability side to side and front to back when being moved and when standing by itself while being operated or serviced.

4.Typical conditions of use such as travel speed, roughness of surface on which the trailer will be operated, environmental conditions, and likely maintenance.

5.Conformance with federal, state and local laws.1

1Consult applicable federal, state and local laws regarding specific requirements for use on public highways.

•Fill the fuel tank at a moderate rate and do not over- fill.

•Wipe up spilled fuel and allow the fumes to clear before starting the engine.

•Keep sparks and flame away from the fuel tank.

•Remove the fuel cap slowly to release pressure.

OIL

The Ranger 250 is shipped with the engine crankcase filled with high quality SAE 10W- 30 oil (API class CD or better). CHECK THE OIL

LEVEL BEFORE YOU START THE ENGINE. If it is not up to the FULL mark on the dipstick, add oil as required. Check the oil every four hours of running time during the first 25 running hours. Refer to the engine operator’s manual for specific oil recommenda- tions and break-in information. The oil change interval is dependent on the quality of the oil and the operating environment. Refer to the engine operator’s manual for the proper service and maintenance intervals.

FUEL

Use gasoline fuel only.

Fill the fuel tank with clean, fresh fuel. The capacity of the fuel tank is 12 gallons (45.4 liters).

NOTE: The fuel tank is mounted below the engine, so a fuel shutoff valve is not required.

ENGINE COOLING SYSTEM

Air to cool the engine is drawn in through the lower set of louvers on the case back. It is important that the intake air is not restricted. Allow a minimum clearance of 2 feet (0.6m) from the case back to a vertical sur- face.
