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.

------------------------------------------------------------------------

See additional warning information at the front of this operator’s manual.

-----------------------------------------------------------

MACHINE GROUNDING

Because this portable engine driven welder / generator creates it’s own power, it is not necessary to connect 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.

------------------------------------------------------------------------

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 connected 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 insulated 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 is provided 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 reg- ulations, the K894-1 spark arrester must be installed and properly maintained.

CAUTION

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(1) is Lincoln’s K957-1. If the user adapts a non-Lincoln trail- er, he must assume responsibility that the method of attachment and usage does not result in a safety haz- ard nor damage the welding 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.

2.Proper support of, and attachment to, the base of the welding equipment so there will be no undue stress to the framework.
