ADDITIONAL SAFETY PRECAUTIONS
WARNING
FALLING EQUIPMENT can cause
injury.
• Do not lift this machine using lift bail if
it is equipped with a heavy accessory
such as trailer or gas cylinder.
• Lift only with equipment of adequate lifting capacity.
• Be sure machine is stable when lifting.
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).
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 vehicle
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.

RANGER 250
PRE-OPERATION ENGINE SERVICE
Read and understand the information about the gaso-
line engine in the Operation and Maintenance sec-
tions of this manual before you operate the Ranger
250.
WARNING
• Keep hands away from the engine muffler or HOT
engine parts.
• Stop the engine and allow it to cool before fueling.
• Do not smoke when fueling.
• 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.
