PRE-OPERATION INSTALLATION

Safety Precautions

WARNING

Do not attempt to use this equipment until you have thoroughly read the engine manufacturers 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

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. (If an older portable welder does not have a grounding stud, connect the ground wire to an unpainted frame screw or bolt.

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 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 U.S. National Electrical Code lists a number of alternate means of grounding electrical equipment.

See additional warning information at

front of this operators manual.

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

Exhaust Spark Arrester

Some federal, state or local laws may require that diesel engines be equipped with exhaust spark arresters when they are operated in certain locations where unarrested sparks may present a fire hazard. The standard mufflers included with these welders do not qualify as a spark arrester. When required by local regulations, suitable spark arresters must be installed and properly maintained.

CAUTION

Use of an incorrect arrester may lead to engine damage or performance loss. Contact the engine manufacturer for specific recommendations.

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

Location / Ventilation

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 the engine exhaust fumes are properly vented to an outside area.

Lift Bail

A lift bail is provided for lifting with a hoist.

WARNING

FALLING EQUIPMENT can cause

injury.

Do not lift this machine using lift bail if

it is equipped with a heavy accessory such as a trailer or gas cylinder.

Lift only with equipment of adequate lifting capacity.

Be sure machine is stable when lifting.

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

Trailers (See Optional Features)

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 dam- age 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.
