SAFETY PRECAUTIONS

WARNING
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.

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.).
WARNING
To prevent dangerous electric shock, other equip-
ment 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.
Do not ground the machine to a pipe that carries
explosive or combustible material.
------------------------------------------------------------------------
INSTALLATION
When this welder is mounted on a truck or trailer, it's
frame must be electrically bonded to the metal frame
of the vehicle. Use a #8 or larger copper wire connect-
ed between the machine grounding stud and the
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 enti-
tled "Standby Power Connections", as well as the arti-
cle on grounding in the latest 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 insulat-
ed joints, or to the metal framework of a building
which has been effectively grounded. The National
Electrical Code lists a number of alternate means of
grounding electrical equipment. A machine grounding
stud marked with the symbol
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 K1898-1 spark arrester must be
installed and properly maintained.
An incorrect arrester may lead to damage to the
engine or adversely affect performance.
------------------------------------------------------------------------

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
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 there will be no undue
stress to the framework.
