Craftsman 316.74520 Manual Del Operador página 23

It is important to prevent gum deposits from forming in
essential fuel system parts such as the carburetor, fuel
filter, fuel hose or tank during storage. Also, experience
indicates that alcohol blended fuels (called gasohol or
using ethanol or methanol) can attract moisture which
leads to separation and formation of acids during
storage. Acidic gas can damage the fuel system of an
engine during storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. Follow
these instructions:
1. Drain all fuel from the fuel tank and drain into a
container with the same 2-cycle fuel mixture. Do not
use fuel that has been stored for more than 60 days.
Dispose of the old fuel/oil mix in a safe manner and
use a fresh mix.
2. Start the engine and allow it to run until it stalls. This
ensures that all fuel has been drained from the
carburetor.
3. Under To Fuel Engine in the Operation section of
this manual, refer to the message labeled
iMPORTANT, regarding the use of gasohol in your
engine.
Fuel stabilizer is an acceptable alternative in
minimizing the formation of fuel gum deposits
during storage. Add stabilizer to the gasoline in
fuel storage container. Follow the mix instructions
found on stabilizer container. Run engine at least
five (5) minutes after adding stabilizer.
Craftsman® 40:1, 2-cycle engine oil is already blended
with fuel stabilizer, if you do not use this Craftsman oil,
you can add a fuel stabilizer to your fuel. NEVER add
fuel stabilizer directly to the unit's fuel tank.
4.
Allow the engine to cool. Remove the spark plug and
put about 1 oz. (30 ml) of any high quality motor oil
or 2-cycle oil into the cylinder. Pull the starter rope
slowly to distribute the oil. Reinstall the spark plug.
NOTE." Remove the spark plug and drain all of the oil from
the cylinder before attempting to start the unit after storage.
.
Thoroughly clean the unit and inspect for any loose
or damaged parts. Repair or replace damaged parts
and tighten loose screws, nuts, or bolts. The unit is
now ready for storage.
6. Store the unit in a dry, well ventilated area and out of
the reach of children.
