Gasoline
Use automotive gasoline (unleaded or low leaded to minimize combustion chamber
deposits) with a minimum of 87 octane. Gasoline with up to 10% ethanol or 15%
MTBE (Methyl Tertiary Butyl Ether) can be used. Never use an oil/gasoline mixture
or dirty gasoline. Avoid getting dirt, dust, or water in the fuel tank. DO NOT use E85
gasoline.
Refuel in a well-ventilated area with the engine stopped. Do not smoke or
allow flames or sparks in the area where the engine is refueled or where
gasoline is stored.
Do not overfill the fuel tank. After refueling, make sure the tank cap is closed
properly and securely.
Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may
ignite. If any fuel is spilled, make sure the area is dry before starting the
engine.
Avoid repeated or prolonged contact with skin or breathing of vapor.
Use extreme care when handling gasoline. Gasoline is extremely
flammable and the vapors are explosive. Never fuel the machine indoors or
while the engine is hot or running. Extinguish cigarettes, cigars, pipes and
other sources of ignition.
1.
Clean around fuel fill before removing cap to fuel.
2.
A fuel level indicator is located in the fuel tank. See Figure 16 inset. Be
careful not to overfill. Fill tank until fuel reaches the fuel level indicator to
allow space for fuel expansion.
Starting The Engine
Always keep hands and feet clear of moving parts. Do not use a pressurized
starting fluid. Vapors are flammable.
NOTE: Allow the engine to warm up for a few minutes after starting. The engine will
not develop full power until it reaches operating temperatures.
1.
Make certain both the auger control and drive control are in the disengaged
(released) position.
2.
Insert key into slot. Make sure it snaps into place. Do not attempt to turn the
key.
NOTE: The engine cannot start without the key fully inserted into the
ignition switch.
OPERATION
WARNING
WARNING
Electric Starter
The electric starter is equipped with a grounded three-wire power plug,
and is designed to operate on 120 volt AC household current. It must be
used with a properly grounded three-prong receptacle at all times to avoid
the possibility of electric shock. Follow all instructions carefully prior to
operating the electric starter. DO NOT use electric starter in the rain.
Determine that your home's wiring is a three-wire grounded system. Ask a licensed
electrician if you are not certain.
If you have a grounded three-prong receptacle, proceed as follows. If you do not
have the proper house wiring, DO NOT use the electric starter under any conditions.
1.
Plug an extension cord into the outlet located on the engine's surface. Plug
the other end of extension cord into a three-prong 120-volt, grounded, AC
outlet in a well-ventilated area.
The extension cord can be any length, but
125 volts, grounded and rated for outdoor use.
2.
Move throttle control to FAST (rabbit)
3.
Move choke to the CHOKE
warm, place choke in RUN position.
4.
Push primer three (3) times, making sure to cover vent hole in primer bulb
when pushing. If engine is warm, push primer only once. Always cover vent
hole when pushing. Cool weather may require priming to be repeated.
5.
Push starter button to start engine. Once the engine starts, immediately
release starter button. Electric starter is equipped with thermal overload
protection; system will temporarily shut-down to allow starter to cool if
electric starter becomes overloaded.
6.
As the engine warms, slowly rotate the choke control to RUN position. If the
engine falters, restart engine and run with choke at half-choke position for a
short period of time, and then slowly rotate the choke into RUN position.
7.
After engine is running, disconnect power cord from electric starter. When
disconnecting, always unplug the end at the wall outlet before unplugging
the opposite end from the engine.
