FUEL SYSTEM
Lead-Free Gasoline Fuel
Use lead-free gasoline with a minimum average octane
rating of 86 or higher.
NOTE:
Do not use gasoline that contains more than 10%
ethanol. If you use gasoline that contains methanol, the
gasoline must contain cosolvents and corrosion inhibitors.
Never use gasoline containing more than 5% methanol.
Fuel Storage
If you keep fuel in storage for a period of time, you can
get foreign material or water in the fuel storage tank.
Many engine problems are caused by water in the fuel.
Fuel Tank Filler Cap
Fill the tank at the end of each day. A full tank will prevent
water condensation.
RT160078
1. FILLER CAP
Always stop the engine and let cool before adding fuel.
When adding fuel to the machine, remove the fuel cap
SLOWLY to reduce any air pressure build up.
Fuel Tank Drain Plug
The fuel tank flow/drain plug is located near the bottom
of the fuel tank. Remove 2 bolts to remove fuel tank.
Inspecting the Fuel Filter
The fuel filter should be checked every 6 months or every
100 hours of operation. Replace the fuel filter every 300
hours of operation or every year.
1. Open the engine access hood. The fuel filter can be
seen from the left side of the engine.
2. Clean the area around the filter.
RT160053
3. Check the fuel filter for water accumulation or
sediment. If no water or sediment is found,
reinstall the fuel filter.
4. If the fuel filter is found with excessive water
accumulation or sediment, take the machine to
your authorized Astec servicing dealer.
Draining the Carburetor For Storage
Gasoline will oxidize and deteriorate in storage. Old
gasoline will cause hard starting, and it leaves gum
deposits that clog the fuel system. If the gasoline in your
engine deteriorates during storage, you may need to have
the carburetor and other fuel system components
serviced or replaced.
The length of time that gasoline can be left in your fuel
tank and carburetor without causing functional problems
will vary with such factors as gasoline blend, your storage
temperatures, and whether the fuel tank is partially or
completely filled. The air in a partially filled fuel tank
promotes fuel deterioration. Vary warm storage/
temperatures accelerate fuel deterioration. Fuel
deterioration problems may occur within a few months, or
even less if the gasoline was not fresh when you filled the
fuel tank.
WARNING:
Engine fuel is flammable and can
cause a fire or an explosion. Do not fill the fuel
tank or service the fuel system near an open
flame,welding, burning cigars, cigarettes, etc.
WARNING:
Never refuel the machine
when the engine is hot or running. Never
smoke while refueling.
WARNING:
Fluid under pressure can
pierce skin and cause injury or death. Stay
away.
