WARNING

Do not attempt to use this equipment until you have thoroughly read the engine manufacturer’s manual supplied with your welder. It includes important safety precautions, detailed engine starting, operating and maintenance instructions, and parts lists.

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

ELECTRIC SHOCK can kill.

•Do not touch electrically live parts or electrode with skin or wet clothing.

•Insulate yourself from work and ground

•Always wear dry insulating gloves.

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

ENGINE EXHAUST can kill.

•Use in open, well ventilated areas or

vent exhaust outside.

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

MOVING PARTS can injure.

•Do not operate with doors open or guards off.

• Stop engine before servicing.

•Keep away from moving parts.

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

LIFTING

The RANGER 250 weighs approximately 575 lbs. with a full tank of gasoline. A lift bail is mounted to the machine and should always be used when lifting the machine.

ADDITIONAL SAFETY PRECAUTIONS

WARNING

FALLING EQUIPMENT can cause injury.

• Do not lift this machine using lift bale if it is equipped with a heavy accessory such as trailer or gas cylinder.

•Lift only with equipment of ade- quate lifting capacity.

•Be sure machine is stable when lifting.

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

HIGH ALTITUDE OPERATION

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

• See additional warning information at front of this operator’s manual.

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

•Only qualified personnel should install, use, or service this equipment.

LOCATION AND VENTILATION

The welder should be located to provide an unrestrict- ed flow of clean, cool air to the cooling air inlets and to avoid restricting the cooling air outlets. Also, locate the welder so that the engine exhaust fumes are prop- erly vented to an outside area.

STACKING

Ranger 250 machines cannot be stacked.

ANGLE OF OPERATION

Engines are designed to run in the level condition which is where the optimum performance is achieved. The maximum angle of continuous operation is 15 degrees in any direction. If the engine is to be operat- ed at an angle, provisions must be made for checking and maintaining the oil level at the normal (FULL) oil capacity in the crankcase.

When operating the welder at an angle, the effective fuel capacity will be slightly less than the specified 12 gallons.

HIGH TEMPERATURE OPERATION

At temperatures above 40°C, output de-rating is nec- essary. For maximum output ratings, de-rate the welder output 2Volts for every 10°C above 40°C.

TOWING

The recommended trailer for use with this equipment for road, in-plant and yard towing by a vehicle(1) is Lincoln’s K957-1. 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 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, i.e., travel speed; rough- ness of surface on which the trailer will be operat- ed; environmental conditions.
