ENGINE OPERATION
STARTING THE ENGINE
1. Open the engine compartment door and check that
the fuel shutoff valve located to the left of the fuel
filter housing is in the open position (lever to be in
line with the hose).
2. Make sure battery disconnect switch is in the on
position.
3. Check for proper oil level and coolant level. Close
engine compartment door.
4. Remove all plugs connected to the AC power
receptacles.
5. Set IDLER switch to "AUTO".
6. Set the RUN/STOP switch to "RUN". Observe that
the engine protection and battery charging lights
are on. After 10 seconds, the engine protection light
will turn off.
7. Within 30 seconds, press and hold the engine
START button until the engine starts.
8. Release the engine START button when the engine
starts.
9. Check that the engine protection and battery charg-
ing lights are off. The engine protection light is on
after starting, the engine will shutdown in a few sec-
onds. Investigate any indicated problem.
10. Allow the engine to warm up at low idle speed for
several minutes before applying a load and/or
switching to high idle. Allow a longer warm up time
in cold weather.
COLD WEATHER STARTING
With a fully charged battery and the proper weight oil,
the engine should start satisfactorily even down to
about 0°F(-18°C). If the engine must be frequently
started below 10°(-12°C), it may be desirable to install
the optional ether start kit (K887-1). For extreme cold
conditions it may be desirable to install the Cold
Weather Heater and Tarp Kit (K2359-1). Installation
and operating instructions are included in the kits.
STOPPING THE ENGINE
1. Switch the RUN/STOP switch to "STOP". This turns
off the voltage supplied to the shutdown solenoid. A
backup shutdown can be accomplished by shutting
off the fuel valve located on the fuel line.
OPERATION
bREAK-IN PERIOD
The engine used to supply power for your welder is a
heavy duty, industrial engine. It is designed and built
for rugged use. It is very normal for any engine to use
small quantities of oil until the break-in is accom-
plished. Check the oil level twice a day during the
break-in period. In general this takes 50 to 100 hours
of operation.
IMPORTANT
IN ORDER TO ACCOMPLISH THIS bREAK-IN, THE
UNIT SHOULD bE SUbJECTED TO HEAVY
LOADS, WITHIN THE RATING OF THE MACHINE.
AVOID LONG IDLE RUNNING PERIODS.
