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 Authorized Service
Center listed in the Yellow Pages. Call 1-866-747-9816
for more information.

STORING A CHAIN SAW

CAUTION:
30 days without performing the following pro-
cedures.
Storing a chain saw for longer than 30 days requires
storage maintenance. Unless the storage instructions
are followed, fuel remaining in the carburetor will evapo-
rate, leaving gum-like deposits. This could lead to diffi-
cult 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-cycle oil into the com-
bustion chamber. Pull starter rope slowly several
times to coat internal components. Replace spark
plug (Fig. 40).
NOTE: Store the unit in a dry place and away from pos-
sible sources of ignition such as a furnace, gas
hot water heater, gas dryer, etc.
