ENGINE OPERATION
DO NOT RUN THE ENGINE AT EXCESSIVE
SPEEDS. The maximum allowable high idle speed
for the GX-271 is 3750 RPM, no load. Do NOT adjust
the governor screw on the engine. Severe personal
injury and damage to the machine can result if it is
operated at speeds above the maximum rated speed.
------------------------------------------------------------------------
Read and understand all safety instructions included
in the Engine Owner’s manual that is shipped with
your GX-271.
BEFORE STARTING THE ENGINE
Check the engine oil level:
1. Be sure the machine is on a level surface.
2. Remove the engine oil dipstick and wipe it with a
clean cloth. Reinsert the dipstick and check the
level on the dipstick.
3. Add oil (if necessary) to bring the level up to the full
mark. Do not overfill.
4. See Engine Owner’s Manual for specific oil recom-
mendations.
Check and fill the engine fuel tank:
GASOLINE can cause fire or
explosion.
• Stop engine when fueling.
• Do not smoke when fueling.
• Do not overfill tank.
• Avoid contact with skin or breathing of vapor.
• Keep sparks and flame away from tank.
------------------------------------------------------------------------
1. Remove the fuel tank cap.
2. Fill the tank approximately 4 inches (100 mm) from
the top of the filler neck to allow for fuel expansion
(observe the fuel gauge.) DO NOT FILL THE
TANK TO THE POINT OF OVERFLOW.
3. Replace the fuel tank cap and tighten securely.
4. See Engine Owner’s Manual for fuel recommenda-
tions.
WARNING
WARNING
STARTING THE ENGINE
Be sure all Pre-Operation Maintenance has been per-
formed. See the INSTALLATION section.
Remove all loads connected to the AC power recepta-
cles and the welder before starting the diesel engine.
------------------------------------------------------------------------
To start the engine, set the “IDLER” switch in the
“AUTO” ( / ) position. Pull the choke
control out.
Place the “Engine” Switch in the “RUN” Position.
Push the “Start” button and crank the engine until it
starts. Release the button as soon as the engine
starts. After the engine has started, slowly return the
choke control to the full “in” position (choke open). In
the “AUTO” position, the engine will run at high idle for
10-14 seconds and then go to low idle. Allow the
engine to warm up by letting it run at low idle for a few
minutes.
At cold temperatures, it may be necessary to start the
engine in “HIGH” idle and allow it to run for several
minutes before using “AUTO” idle.
When starting a hot engine, it is not necessary to pull
the choke out but the engine will start faster if it is
pulled out. Push it in immediately after the engine
starts.
Operating the starter motor for more than 5 seconds
can damage the motor. If the engine fails to start,
release the switch and wait 10 seconds before operat-
ing the starter again. Do not push the “Start” button
while the engine is running because this can damage
the ring gear and/or starter motor.
------------------------------------------------------------------------
NOTE: When starting a GX-271 for the first time, after
an extended period of not operating, it will take longer
than normal because the fuel pump has to fill the fuel
line and carburetor.
