VANTAGE® 300
NOTE: If the unit fails to start turn run/stop switch to
off and repeat step 3 through step 7 after waiting 30
seconds.
• Do not allow the starter motor to run continuously
for more than 20 seconds.
• Do not push the START button while the engine
is running because this can damage the ring
gear and/or the starter motor.
• IF the Engine Protection or Battery Charging
Lights do “not” turn off shortly after starting the
engine shut off the engine immediately and deter
mine the cause.
-----------------------------------------------------------------------
NOTE: When starting for the first time, or after and
extended period of time of not operating, it will take
longer than normal to start because the fuel pump has
to fill the fuel system. For best results, bleed the fuel
system as indicated in Maintenance Section of this
manual.
STOPPING THE ENGINE
Remove all welding and auxiliary power loads and
allow the engine to run at low idle speed for a few
minutes to cool the engine.
STOP the engine by placing the RUN-STOP switch in
the STOP position.
NOTE: A fuel shut off valve is located on the fuel pre-
filter.
WELDER OPERATION
DUTY CYCLE
Duty Cycle is the percentage of time the load is being
applied in a 10 minute period. For example a 60% duty
cycle, represents 6 minutes of load and 4 minutes of no
load in a 10 minute period.
ELECTRODE INFORMATION
For any electrode the procedures should be kept with-
in the rating of the machine. For information on elec-
trodes and their proper application see
(www.lincolnelectric.com) or the appropriate Lincoln
publication.
The VANTAGE® 300 can be used with a broad range of
DC stick electrodes. The MODE switch provides two
stick welding settings as follows:
CAUTION
17. ENGINE PROTECTION LIGHT- A warning indi-
cator light for Low Oil Pressure and/or Coolant Over
Temperature. The light is off when the systems are
functioning properly. The light will come on and the
engine will shutdown when there is Low Oil Pressure
and/or the Coolant is Over Temperature.
Note: The light remains off when the RUN-STOP switch
is in the "ON" position prior to starting the engine.
However if the engine is not started within 60 seconds
the light will come on. When this happens, the RUN-
STOP switch must be returned to the "OFF" position to
reset the engine protection system and light.
18. BATTERY CHARGING LIGHT- A warning indica-
tor light for Low/No battery charge. The light is off when
the systems are functioning properly. The light will
come on if there is a Low/No battery condition but the
machine will continue to run.
Note: The light will come on when the RUN-STOP switch
is in the "ON" position prior to starting the engine. After
starting the engine the light will go off unless a Low/No
battery charge condition exists.
19. COOLANT TEMPERATURE GAUGE- The
electric temperature gauge gives accurate indication of
coolant temperature.
20. OIL PRESSURE GAUGE- A indicator of engine
Oil Pressure.
STARTING THE ENGINE
1. Remove all plugs connected to the AC power
receptacles.
2. Set IDLER switch to AUTO.
3. Press Glow Plug Button and hold 15 to 20 sec-
onds.
4. Set the RUN/STOP switch to RUN.
5. Press START button until the engine starts or for
up to 10 seconds. Continue to hold the glow plug

7. The engine will run at high idle speed for approxi-
mately 12 seconds and then drop to low idle speed.
Allow the engine to warm up at low idle for several
minutes before applying a load and/or switching to
high idle. Allow a longer warm up time in cold
weather.
