HIGH ALTITUDE OPERATION

At higher altitudes, output derating may be necessary. As a rule of thumb, derate the welder output 5% for every 500 meters (1640 ft.) above 1000 meters (3280 ft.).

Contact a Perkins Service Representative for any engine adjustments that may be required for high alti- tude operation.

TOWING

The recommended trailers for use with this equipment for in-plant and yard towing by a vehicle(1) are Lincoln’s K767-1, K956-1 and K956-2. The K956-1 and K956-2 are also designed to be used at highway speeds(1).If the user adapts a non-Lincoln trailer, he must assume responsibility that the method of attachment and usage does not result in a safety hazard nor damage the welding equipment. Some of the factors to be consid- ered 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 that there will be no undue stress to the trailer’s 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.

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

5.Proper preventative maintenance of trailer.

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

(1)For highway use, consult applicable federal, state and local laws regarding specific requirements for use on public highways, such as brakes, lights, fend- ers, etc.

PRE-OPERATION ENGINE AND COMPRESSOR SERVICE

READ the engine and compressor operating and main- tenance instructions supplied with this machine.

ENGINE OIL

The WELD’N AIR is shipped with the engine crankcase filled with high quality SAE 10W-30 oil (API class CD or better). Check the oil level before starting the engine. If it is not up to the full mark on the dip stick, add oil as required. Check the oil level every four hours of running time during the first 35 running hours. Refer to the engine Operator’s Manual for specific oil recommendations 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 ser- vice and maintenance intervals.

AIR COMPRESSOR OIL

The WELD’N AIR is shipped with the compressor filled with a high quality synthetic compressor oil. If oil is needed add only Iowa Mold Tooling Co., Inc. (IMT) syn- thetic compressor oil until compressor is full.

CAUTION

The use of any other oil causes excessive carbon build up, and will void the warranty on the compressor.

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

Check the oil level daily. Refer to the compressor Operator’s Manual for the proper service and mainte- nance intervals.

FUEL USE DIESEL FUEL ONLY

WARNING

•Stop engine and allow to cool before fueling.

•Do not smoke when fueling.

•Fill fuel tank at a moderate rate and do not overfill.

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

•Keep sparks and flame away from tank.

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

Fill the fuel tank with clean, fresh diesel fuel. The capac- ity of the fuel tank is 22.5 gallons (85.1 liters). See engine Operator’s Manual for specific fuel recommendations.
