SAE-400™
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 adjust-
ments that may be required for high altitude 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 and K956-1.
The K956-1 is 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 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 that there will be no undue stress to the trailer’s
framework.
3. Proper placement of the equipment on the trailer to insure sta-
bility 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 environmen-
tal conditions.
5. Proper preventative maintenance of trailer.
6. Conformance with federal, state and local laws.

PRE-OPERATION ENGINE SERVICE
READ the engine operating and maintenance instructions supplied
with this machine.
ENGINE OIL
The engine is shipped with the engine crankcase filled with high qual-
ity 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 service and maintenance intervals.
