BEFORE STARTING THE ENGINE

Check and fill 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. On the Onan engine, the oil
fill cap and dipstick are a unit. See Figure D.1 in
the Maintenance section of this manual.
3. Add oil (if necessary) to bring the level up to the
full mark. Do not overfill.
Replace the dipstick and tighten it securely.
Check and fill the engine fuel 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.
NOTE: Use only fresh, unleaded gasoline with octane
rating 87 or higher. Gasoline/alcohol blends are
approved for use with your engine as long as the blend
does not exceed 10% ethyl alcohol by volume. Other
gasoline/alcohol blends are not approved, and their
use may damage fuel system and engine parts.
NOTE: Purchase gasoline in quantities that will be
used within 30 days, to assure freshness.

STARTING THE ENGINE

NOTE: Remove all loads connected to the AC power
receptacles before starting the gasoline engine.
For a "cold" engine:
1. Set the Idler Control Switch in
the AUTO position.
Use the Choke Control as follows:
If the engine is cold, pull the choke
control out. If the engine is warm or
hot, DO NOT use the choke control.

OPERATION
2. Hold the Engine Switch in the START
position. Release the switch when the
engine starts. Slowly return the choke
control to the full "in" position.
The engine will run at high idle for 10-14 seconds,
then go to low idle.
3. Let the engine run at low idle for a few minutes to
warm up before you use the RANGER 9 for weld-
ing or auxiliary power.
If the engine will not start, see the Trouble-
shooting section of this manual.

STOPPING THE ENGINE

1. Remove all welding and generator power loads
and let the engine cool by running it for several
minutes at low idle.
2. Stop the engine by placing the Engine
Switch in the STOP position.
A fuel shutoff valve is not required on the
RANGER 9 because the fuel tank is mounted
below the engine.
BREAK-IN PERIOD
Any engine will use a small amount of oil during its

"break-in" period.

RANGER 9, break-in is about 50 running hours.
Check the oil at least twice a day during break-in.
Change the oil after the first 25 hours of operation.
Change the oil filter at the second oil change. For
more details, see the Maintenance section of this
manual.
During break-in, subject the RANGER 9 to moderate
loads. Avoid long periods running at idle. Before
stopping the engine, remove all loads and allow the
engine to cool several minutes.
