Mixing Gasoline And Oil - Toro 53002 Operator's Manual

4. Always open the fuel tank cap slowly to release any
possible overpressure inside the tank.
5. Do not overfill the fuel tank. Stop filling 1/4–1/2 inch
(6mm–13mm) from the top of the tank.
6. Tighten the tank fuel cap carefully but firmly after
refilling.
7. Wipe up any spilled fuel before starting the engine.
8. Move the String Trimmer at least 10 feet (3 m) away
from the fueling location and fuel storage container
before starting the engine (Fig. 2).
Recommended Oil Type
Only use a two-cycle engine oil formulated for use in
high-performance, air-cooled two-cycle engines. Toro
brand 2-cycle oil is formulated for use in
high-performance, air-cooled two-cycle engines.
IMPORTANT: Do not use National Marine
Manufacturer's Association (NMMA) or BIA certified
oils. This type of 2–cycle engine oil does not have the
proper additives for air-cooled, 2–cycle engines and
can cause engine damage.
Do not use automotive motor oil. This type of
oil does not have the proper additives for
air-cooled, 2–cycle engines and can cause
engine damage.
Recommended Fuel Type
Use clean, fresh lead-free gasoline, including oxygenated
or reformulated gasoline, with an octane rating of 85 or
higher. To ensure freshness, purchase only the quantity of
gasoline that can be used in 30 days. Use of lead-free
gasoline results in fewer combustion chamber deposits
and longer spark plug life. Use of premium grade fuel is
not necessary or recommended.
Use Of Fuel Additives
IMPORTANT: NEVER USE METHANOL,
GASOLINE CONTAINING METHANOL,
GASOHOL CONTAINING MORE THAN
10% ETHANOL, PREMIUM GASOLINE,
OR WHITE GAS BECAUSE ENGINE
FUEL SYSTEM DAMAGE COULD
RESULT.
DO NOT USE FUEL ADDITIVES OTHER
THAN THOSE MANUFACTURED FOR
FUEL STABILIZATION DURING
STORAGE SUCH AS TORO'S
STABILIZER/CONDITIONER OR A
SIMILAR PRODUCT. TORO'S
STABILIZER/CONDITIONER IS A
PETROLEUM DISTILLATE BASED
CONDITIONER/STABILIZER.
TORO DOES NOT RECOMMEND
STABILIZERS WITH AN ALCOHOL BASE
SUCH AS ETHANOL, METHANOL OR
ISOPROPYL. ADDITIVES SHOULD NOT
BE USED TO TRY TO ENHANCE THE
POWER OR PERFORMANCE OF
MACHINE.

Mixing Gasoline And Oil

IMPORTANT: The engine used on this String Trimmer
is of a 2–cycle design. The internal moving parts of the
engine, i.e., crankshaft bearings, piston pin bearings
and piston to cylinder wall contact surfaces, require oil
mixed with the gasoline for lubrication.
Failure to add oil to the gasoline or failure to
mix oil with the gasoline at the appropriate
ratio will cause major engine damage which
will void your warranty.
For your fuel premix, only use a quality oil
designed for 2–cycle air cooled engines. Toro
50:1 2–Cycle Oil is formulated to meet the
requirements of high-performance, air-cooled
two-cycle engines.
Fuel Mixture
The fuel:oil ratio is 50 parts gasoline to 1 part oil or 50:1.
Note: Never use a mixing ratio less than 50:1
regardless of the oil package mixing instructions.
Ratios less the 50:1, (for example, 60:1, 80:1, 100:1),
reduce the amount of lubrication to the internal
moving parts of the engine and can cause damage.
