Oil And Fuel Information; Fueling The Unit - Cub Cadet ST428 Operator's Manual

WARNING:
OVERFILLING OIL CRANKCASE MAY CAUSE
SERIOUS PERSONAL INJURY. Check and maintain the proper oil
level in the crank case; it is important and cannot be
overemphasized. Check the oil before each use and change it as
needed. See Changing the Oil.
RECOMMENDED OIL TYPE
Using the proper type and weight of oil in the crankcase is extremely
important. Use a high-quality SAE 30 weight oil of API (American Petroleum
Institute) service class SJ.
Check the oil before each use and change the oil regularly. Failure to use the
correct oil, or using dirty oil, can cause premature engine wear and failure.
ADDING OIL TO CRANKCASE: INITIAL USE
NOTE: This unit is shipped without oil. In
order to avoid damage to the unit, put
oil in the crankcase before you
attempt to start the unit.
Your unit is supplied with one 2.2 fl.oz. (60 ml)
bottle of SAE 30 SJ oil (Fig. 20).
NOTE: Save the bottle of oil. It can be used to
measure the correct amount during
future oil changes. See Changing the Oil.
1. Unscrew the top of the bottle of oil and
remove the paper seal covering the opening.
Replace the top. Next, cut the tip off the
funnel spout (Fig. 20).
2. Place unit on a flat, level surface.
3. Remove the oil fill plug from the crankcase.
4. Pour the entire bottle of oil into the oil fill hole
(Fig. 21).
NOTE: Never add oil to the fuel or fuel tank.
5. Wipe up any oil that may have spilled and reinstall the oil fill plug.
Check oil before each use and change as needed. Refer to Checking the Oil
Level.

RECOMMENDED FUEL TYPE
Old fuel is the primary reason for improper unit performance. Be sure to use
fresh, clean, unleaded gasoline.
NOTE: This is a four cycle engine. In order to avoid damage to the unit, do
not mix oil with gasoline.
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and oxygenates such as ethanol,
methanol or MTBE (ether). Alcohol-blended fuel absorbs water. As little as 1%
water in the fuel can make fuel and oil separate or form acids when stored.
Use fresh fuel (less than 30 days old), when using alcohol-blended fuel.
Using Blended Fuels
WARNING:
DO NOT USE E85 FUEL IN THIS UNIT. It has
been proven that fuel containing greater than 10% ethanol will
likely damage this engine and void the warranty.
If you choose to use a blended fuel, or its use is unavoidable, follow
recommended precautions:
• Always use fresh unleaded gasoline
• Use the fuel additive STA-BIL® or an equivalent
• Drain tank and run the engine dry before storing unit
Using Fuel Additives
The use of fuel additives, such as STA-BIL® Gas Stabilizer or an equivalent,
will inhibit corrosion and minimize the formation of gum deposits. Using a
fuel additive can keep fuel from forming harmful deposits in the carburetor
for up to six (6) months. Add 0.8 oz. (23 ml) of fuel additive per gallon of fuel
according to the instructions on the container. NEVER add fuel additives
directly to the unit's gas tank.

FUELING THE UNIT

WARNING:
Add fuel in a clean, well ventilated outdoor area. Wipe
up any spilled fuel immediately. Avoid creating a source of ignition for
spilt fuel. Do not start the engine until fuel vapors dissipate.
WARNING:
Gasoline is extremely flammable. Ignited vapors
may explode. Always stop the engine and allow it to cool before
filling the fuel tank. Do not smoke while filling the tank. Keep
sparks and open flames at a distance from the area.
WARNING:
Remove fuel cap slowly to avoid injury from fuel
spray. Never operate the unit without the fuel cap securely in place.
1. Remove the fuel cap (Fig. 22).
2. Place the gas container's spout into the fill
hole on the fuel tank (Fig. 22) and fill the tank.
NOTE: Do not overfill the tank.
3. Wipe up any gasoline that may have spilled.
4. Reinstall the fuel cap.
5. Move the unit at least 30 ft. (9.1 m) from the
fueling source and site before starting the
engine.
NOTE: Dispose of the old gasoline in accordance with federal, state and
local regulations.
