Changing The Oil; Recommended Fuel Type; Definition Of Blended Fuels; Use Of Blended Fuels - Toro AC-1 Service Manual

Changing the Oil
For a new engine, change the oil after the first 10
hours of operation. Thereafter, change the oil after
every 25 hours or before storing the unit for an ex-
tended period of time.
Change the oil while the engine is still warm. The oil
will flow freely and carry away more impurities.
Change the oil as follows:
1. Remove the oil fill plug.
2. Pour the oil into a container by
t i p p i n g
in a vertical position (Figure 1-7
tipping the trimmer
7). Be sure to allow
ample time for complete drainage. Dispose of oil
properly.

3. Fill the oil pan, with 3.4 oz
(100
ml) of new oil of the
proper type, to the top of the dipstick.
4.
Reinstall the oil fill plug and tighten securely.
NOTE: Make sure the O-ring is in place on the oil fill
plug when checking and changing the oil.
NOTE: To prevent extensive engine wear or damage,
always maintain the proper oil level in the crankcase.
Never operate the engine with the oil level below the
bottom of the dipstick
Recommended Fuel Type
Use clean, fresh, regular grade unleaded gasoline les
than 60 days old.
NOTE: Alcohol blended fuel absorbs moisture
(water). As little as 1 % moisture in the fuel can cause
fuel to separate and form acids when stored.
If these types of fuel must be used, use fresh fuel (less
than 60 days old).
Definition of Blended Fuels
Today's fuels are often a blend of gasoline and one O r
more oxygenates such as ethanol, methanol or MTBE
(ether).
Use of Blended Fuels
If you choose to use a blended fuel or its use is un-
avoidable, the following precautions are recom-
mended.
1. Always use fresh fuel.
2. Use the special additive Toro Gas Conditioner/
Stabilizer, STA-BIL (R) or an equivalent.
3. Drain the fuel tank and run the engine dry before
storing the unit.
Use of Fuel Additives
The use of fuel additives, such as Toro Gas Condi-
tioner/Stabilizer, STA-BIL Gas Stabilizer or an equiva
lent, will inhibit corrosion and minimize the formation
of gum deposit. Add
0 . 8
oz (23 ml) per gallon of fuel
per instructions on the container. NEVER add fuel a
ditives directly to the unit's fuel tank. Using a fuel ad
tive can keep fuel fresh for up to 60 days.
