Some federal, state or local laws may require that
engines be equipped with exhaust spark arresters
when they are operated in certain locations where
unarrested sparks may present a fire hazard. The
standard muffler included with this welder does not
qualify as a spark arrester. When required by local
regulations, a suitable spark arrester must be installed
and properly maintained.
Use of an incorrect arrester may lead to engine damage
or performance loss. Contact the engine manufacturer
for specific recommendations.

Always operate the welder with the doors closed.
Leaving the doors open changes the designed air flow
and may cause overheating.
The welder should be located to provide an unrestrict-
ed flow of clean, cool air. Also, locate the welder so
that engine exhaust fumes are properly vented to an
outside area.

According to the United States National Electrical
Code, the frame of this portable generator is not
required to be grounded and is permitted to serve as
the grounding means for cord connected equipment
plugged into its receptacle.
Some state, local, or other codes or unusual operating
circumstances may require the machine frame to be
grounded. It is recommended that you determine the
extent to which such requirements may apply to your
particular situation and follow them explicitly. A
machine grounding stud marked with the symbol is
provided on the welding generator frame foot. In gen-
eral, if the machine is to be grounded, it should be
connected with a #8 or larger copper wire to a solid
earth ground such as a metal water pipe going into
the ground for at least ten feet and having no insulat-
ed joints, or to the metal framework of a building
which has been effectively grounded. The U.S.
National Code lists a number of alternate means of
grounding electrical equipment.

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 weld-
ing equipment. Some of the factors to be considered are
as follows:
1. Design capacity of trailer vs. weight of Lincoln equip-
ment and likely additional attachments.
