VANTAGE ® 300
• 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 sys-
tem as indicated in Maintenance Section of this manual.
CAUTION
ENGINE CONTROLS:
12. RUN/STOP SWITCH - RUN position ener-
gizes the engine prior to starting. STOP posi-
tion stops the engine. The oil pressure interlock switch
prevents battery drain if the switch is left in the RUN
position and the engine is not operating.
13. GLOW PLUG PUSH BUTTON -
• When pushed activates the glow plugs. Glow
plug should not be activated for more than 20
seconds continuously.
14. START PUSH BUTTON - Energizes the starter motor
to crank the engine.
15. IDLER SWITCH - Has two positions as follows:
1) In the HIGH position, the engine runs at the high
idle speed controlled by the engine governor.
2) In the AUTO position, the idler operates as
follows:
• When switched from HIGH to AUTO or after starting the
engine, the engine will operate at full speed for approxi-
mately 12 seconds and then go to low idle speed.
• When the electrode touches the work or power is drawn
for lights or tools (approximately 100 Watts minimum), the
engine accelerates and operates at full speed.
• When welding ceases or the AC power load is turned off, a
fixed time delay of approximately 12 seconds starts. If the
welding or AC power load is not restarted before the end
of the time delay, the idler reduces the engine speed to
low idle speed.
• The engine will automatically return to high idle speed
when there is welding load or AC power load reapplied.
16. ELECTRIC FUEL GAUGE- The electric fuel
gauge gives accurate and reliable indication as to how
much fuel is in the fuel tank.
17. ENGINE HOUR METER- Displays the total time
that the engine has been running. This meter is useful
for scheduling prescribed maintenance.
18. 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 func-
tioning 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" posi-
tion to reset the engine protection system and light.
19. BATTERY CHARGING LIGHT- A warning
indicator 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 may or may not come on when the RUN-
STOP switch is in the "ON" position. It will come on during
cranking and stay on until the engine starts. After starting
the engine the light will go off unless a Low/No battery
charge condition exists.
20. COOLANT TEMPERATURE GAUGE- A indica-
tor of engine coolant temperature.
21. OIL PRESSURE GAUGE- A indicator of engine
Oil Pressure.
22. CIRCUIT BREAKER- For protection of Battery
Charging Circuit.
23. CIRCUIT BREAKER- For protection of 42V Wire
Feeder circuit.
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 seconds.
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 button for up to an
additional 10 seconds.
6. Release the engine START button immediately when the
engine starts.
7. The engine will run at high idle speed for approximately 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.
NOTE: If the unit fails to start turn run/stop switch to off and
repeat step 3 through step 7 after waiting 30 seconds.
