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
K767-1, K956-1 and K956-2. The K956-1 and K956-2
are also designed to be used at highway speeds
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.
