STACKING
RANGER 9 machines CANNOT be stacked.
TILTING
Place the machine on a secure, level surface whenev-
er you use it or store it. Any surfaces you place it on
other than the ground must be firm, non-skid, and
structurally sound.
The gasoline engine is designed to run in a level posi-
tion for best performance. It can operate at an angle,
but this should never be more than 15 degrees in any
direction. If you do operate it at a slight angle, be sure
to check the oil regularly and keep the oil level at the
FULL mark as it would be in its normal level condition.
Also, fuel capacity will be a little less at an angle.
LIFTING
The RANGER 9 weighs 562 lbs/255 kg. A lift bail is
mounted to the generator stator frame and should
always be used when lifting the machine.
HIGH ALTITUDE OPERATION
If you operate the RANGER 9 at altitudes above 5000
feet, you should install a carburetor jet designed for
high altitude operation. This will result in better fuel
economy, cleaner exhaust, and longer spark plug life.
It won’t give increased power. Power is decreased at
higher altitudes. Contact the engine manufacturer to
obtain these high altitude jet kits (Onan kit part num-
ber 146-0458).
Do not operate a RANGER 9 with a high altitude jet
installed at altitudes below 5000 feet. The engine will
run too lean and operate at higher engine tempera-
tures, which can shorten engine life.
PRE-OPERATION ENGINE SERVICE
Read and understand the information about the gaso-
line engine in the Operation and Maintenance sec-
tions of this manual before you operate the RANGER
9.
• Keep hands away from the engine muffler or HOT
engine parts.
• Stop the engine when fueling.
• Do not smoke when fueling.
• Remove the fuel cap slowly to release pressure.
• Do not overfill the fuel tank.
• Wipe up spilled fuel and allow the fumes to clear
before starting the engine.
• Keep sparks and flame away from the fuel tank.
OIL
The RANGER 9 is shipped with the engine
filled with SAE 10W-30 oil. CHECK THE
OIL LEVEL BEFORE YOU START THE ENGINE. This
is an added precaution. When full, the oil level should
be up to but not over the FULL mark on the dipstick.
If it is not full, add enough oil to fill it to the full mark.
For more oil fill and service information, see the
MAINTENANCE section of this manual.
FUEL
Fill the fuel tank with clean, fresh, regular
grade lead-free gasoline. DO NOT MIX
OIL WITH THE GASOLINE.
The RANGER 9 has a 9 gallon (34.1 litre),
bottom mounted fuel tank with a top fill and fuel
gauge. See the Operation and Maintenance sec-
tions of this manual for more details about fuel.
BATTERY CONNECTIONS
The RANGER 9 is shipped with the nega-
tive battery cable disconnected. Before
you operate the machine, make sure the Engine
Switch is in the STOP position and attach the discon-
nected cable securely to the battery terminal. If the
battery is discharged and won’t start the engine, see
the battery charging instructions in the Maintenance
section.
