STOPPING THE ENGINE
(GASOLINE OR DIESEL)
1. Place the IGNITION switch in the OFF position.
At the end of each day’s welding, drain accumulated
dirt and water from the sediment bowl under the fuel
tank and from the fuel filter (diesel engine, Classic IIID)
per instructions in the engine manufacturer’s operating
manual. Refill the fuel tank to minimize moisture con-
densation in the tank. Also, running out of fuel tends to
draw dirt into the fuel system. Check the crankcase oil
level.
When hauling the welder between job sites, close the
fuel feed valve beneath the tank. In gasoline engines,
failing to turn off the fuel when traveling can cause car-
buretor flooding and difficult starting at the new job site.
In diesel engines, 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. See “How to Eliminate
Air From the Fuel System” in the
Maintenance
section.
BREAK-IN PERIOD
When an engine is started for the first time, some of the
oil will be needed to fill the passages of the lubricating
system. Therefore, on initial starting, run the engine for
about five minutes and then stop the engine and
recheck the oil. If the level is down, fill to the full mark
again.
The engine controls were properly set at the factory
and should require no adjusting when received.
Any engine will use a small amount of oil during its
break-in period. For the gasoline or diesel engine on
the Classic III or Classic IIID, break-in is about 200 run-
ning hours.
Check the oil twice a day during break-in. Change the
oil and oil filter cartridge after the first 25 hours of oper-
ation. Also change the fuel filter cartridge on the diesel
engine. For more details, see the
Maintenance
sec-
tion of this manual.
During break-in, subject the Classic III or Classic IIID to
only moderate loads. Avoid long periods running at
idle. Before stopping the engine, remove all loads and
allow the engine to cool several minutes.
