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 the 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 SAE-300® 404D-22 DIESEL ENGINE
1.Turn the “IDLER” switch to “HIGH”.
2.Turn the “IGNITION” switch to “ON”.
3.Press the Glow Plug button for 20 to 30 seconds. (maximum 60 seconds).
4.Press the Start button. When the engine starts running, release both buttons. If the engine fails to start in 20 seconds, wait 30 seconds and repeat the above procedure.
5.Observe the oil pressure. If no pressure shows within 30 seconds, stop the engine and consult the engine operating manual. To stop the engine, turn the “IGNITION” switch to “OFF”.
6.If the engine protection warning light comes on during cranking or after start up, the “IGNITION” switch must be turned “OFF” to reset the engine protection system.
7.Allow the engine to run at high idle speed for sev- eral minutes to warm the engine. Stop the engine and recheck the oil level, after allowing sufficient time for the oil to drain into the pan. If the level is down, fill it to the full mark again. The engine con- trols were properly set at the factory and should require no adjusting when received.
COLD WEAThER STARTING:
With a fully charged battery and the proper weight oil, the engine should start satisfactorily even down to about
Note: Extreme cold weather starting may require longer glow plug operation.
WARNING
under NO conditions should ether or other starting fluids be used!
hIGh ALTITuDE OPERATION:
The engine will run correctly up to an altitude of 600m (2000ft.). If the engine is to be operated permanently at an altitude above this, the fuel consumption and exhaust emissions may be excessive.
Contact the Perkins Application Department for any engine adjustments that may be required.
STOPPING ThE ENGINE
1. Turn the “IGNITION” switch to “OFF”
At the end of each day’s welding, check the crankcase oil level, drain accumulated dirt and water from the water separator located on the fuel rail. Refill the fuel tank to minimize moisture condensation in the tank. Also, running out of fuel tends to draw dirt into the fuel system.
When hauling the welder between job sites, close the fuel feed valve on the separator located on the fuel rail.
If the fuel supply is cut off or runs out while the fuel pump is operating, air may be entrapped in the fuel distribution system. If this happens, bleeding of the fuel system may be necessary. Use qualified person- nel to do this per the instructions in the MAINTE- NANCE section of this manual.
