SAFETY PRECAUTIONS

WARNING

Do not attempt to use this equipment until you have thoroughly read all operating and maintenance man- uals supplied with your machine. They include impor- tant safety precautions, detailed engine starting, operating and maintenance instructions and parts lists.

ELECTRIC SHOCK can kill.

•Do not touch electrically live parts such as output terminals or internal wiring.

•Insulate yourself from the work and ground.

•Always wear dry insulating gloves.

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

ENGINE EXHAUST can kill.

•Use in open, well ventilated areas or vent exhaust outside

•Do not stack anything near the engine.

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

MOVING PARTS can injure.

•Do not operate with doors open or guards off.

•Stop engine before servicing.

•Keep away from moving parts

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

Only qualified personnel should install, use or service this equipment

LOCATION/VENTILATION

The welder should be located to provide an unrestricted flow of clean, cool air to the cooling air inlets and to avoid restricting the cooling air outlets. Also, locate the welder so that the engine exhaust fumes are properly vented to an outside area.

CAUTION

DO NOT MOUNT OVER COMBUSTIBLE SURFACES.

Where there is a combustible surface directly under stationary or fixed electrical equipment, that surface shall be covered with a steel plate at least .06”(1.6mm) thick, which shall extend not less than 5.90”(150mm) beyond the equipment on all sides.

STACKING

These machines cannot be stacked.

ANGLE OF OPERATION

To achieve optimum engine performance the machine should be run in a level position. The maximum angle of operation for the Perkins engine is 30 degrees in all directions. If the engine is to be operated at an angle, provisions must be made for checking and maintaining the oil level at the normal (FULL) oil capacity in the engine crankcase. When operating the welder at an angle, the effective fuel capacity will be slightly less than the specified 22.5 gallons.

LIFTING

The equipment lift bale should be used to lift the machine.

WARNING

 

• Lift only with equipment of

 

adequate lifting capacity.

 

• Be sure machine is stable

 

when lifting.

 

• Do not lift this machine using

 

lift bale if it is equipped with a

 

heavy accessory such as trail-

 

er or gas cylinder.

FALLING

• Do not lift machine if lift bale

 

is damaged.

EQUIPMENT can

• Do not operate machine while

cause injury.

suspended from lift bale.
