SAFETY PRECAUTIONS
MACHINE GROUNDING
Because this portable engine driven welder or genera-
tor creates it’s own power, it is not necessary to con-
nect it’s frame to an earth ground, unless the machine
is connected to premises wiring (your home, shop,
etc.).
To prevent dangerous electric shock, other equipment
to which this engine driven welder supplies power
must:
• Be grounded to the frame of the welder using a
grounded type plug, or
• Be double insulated.
When this welder is mounted on a truck or trailer, it’s
frame must be securely connected to the metal frame
of the vehicle.
Where this engine driven welder is connected to
premises wiring such as that in your home or shop,
it’s frame must be connected to the system earth
ground. See further connection instructions in the
section entitled “Standby Power Connections”, as well
as the article on grounding in the latest U.S. National
Electrical Code and the local code.
In general, 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
insulated joints, or to the metal framework of a build-
ing which has been effectively grounded. The U.S.
National Electrical Code lists a number of alternate
means of grounding electrical equipment. A machine
grounding stud marked with the symbol is provid-
ed on the front of the welder.
SPARK ARRESTER
Some federal, state, or local laws may require that
gasoline 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, the K894-1 spark arrester must be
installed and properly maintained.
An incorrect arrester may lead to damage to the
engine or adversely affect performance.

UNDERCARRIAGES
The recommended trailer for use with this equipment
for in plant and yard towing by a vehicle (1) is
Lincoln’s K768-2. If the user adapts a non-Lincoln
undercarriage, 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:
• Design capacity of undercarriage vs. weight of
Lincoln equipment and likely additional attach-
ments
• Proper support of, and attached to, the base of the
welding equipment so there will be no undue stress
to the frame work.
• Proper placement of the equipment on the under-
carriage to ensure stability side to side and front to
back when being moved and when standing by
itself while being operated or serviced.
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.
