Lincoln Electric SA-250 manual Engine Operation, Starting the Perkins D3.152 Engine

ENGINE OPERATION

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 front of this operator’s manual.

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

Operate the welder with the doors closed. Leaving the doors open changes the designed air flow and can cause overheating.

Starting the Perkins D3.152 Engine

a)Turn the idler control to “HIGH”.

b)Turn the ignition control to “ON”.

c)Push in the “RESET” button.

d)Press the “START” button. Release button when engine starts.

e)If the engine fails to start in 60 seconds, wait 30 seconds before repeating the above procedure.

f)Allow the engine to run at high idle speed for sever- al minutes to warm up. Cold engines tend to run at a speed too slow to supply the voltage required for proper idler operation.

Cold Weather Starting -- When overnight tempera- tures are between 10°F (-12°C) and freezing, use the standard “Thermostart” starting system installed on all engines. Follow the instructions on the nameplate and in the engine manual shipped with the welder. With fully charged batteries and the proper weight oil, the “Thermostart” system operates satisfactorily even down to about 0°F (-18°C).

If the engine must be frequently started below 10°F (-12°C), it may be desirable to remove the “Thermostart” and install the optional ether starter kit. Installation and operating instructions are included in the kit. Use ether starting only when required because excessive use shortens engine life.

Stopping the Perkins D3.152 Engine

a) Turn the ignition control to “OFF”.

At the end of each day’s welding, refill the fuel tank to minimize moisture condensation in the tank. Also, running out of fuel tends to draw dirt into the fuel sys- tem.

Check the crankcase oil and radiator water level.
