CARBURETOR ADJUSTMENT
The carburetor was pre-set at the factory for optimum
performance. If further adjustments are necessary,
please take your unit to the nearest professional.
•
STORING A CHAIN SAW
Storing a chain saw for longer than 30 days requires
storage maintenance. Unless the storage instructions are
followed, fuel remaining in the carburetor will evaporate,
leaving gum-like deposits. This could lead to difficult
starting and result in costly repairs.
1.
Remove the fuel tank cap slowly to release any
pressure in tank. Carefully drain the fuel tank.
2.
Start the engine and let it run until the unit stops to
remove fuel from carburetor.
3.
Allow the engine to cool (approx. 5 minutes).
4.
Using a spark plug wrench, remove the spark plug.
5.
Pour 1 teaspoon of clean 2-stroke oil into the
combustion chamber. Pull starter rope slowly
several times to coat internal components. Replace
spark plug (Fig. 22).
NOTE: Store the unit in a dry place and away from
possible sources of ignition such as a furnace, gas hot
water heater, gas dryer, etc.
Fig. 18
CAUTION: Never operate your saw without
a fuel filter. The fuel filter should be replaced
after each 20 hours of use. Drain fuel tank
completely before changing filter.
