7-6.CARBURETOR ADJUSTMENT

The carburetor was pre-set at the factory for optimum per- formance. If further adjustments are necessary, please take your unit to the nearest Authorized Service Center list- ed in the Yellow Pages.

7-7.STORING A CHAIN SAW

CAUTION

Never store a chain saw for longer than 30 days without performing the following procedures.

Storing a chain saw for longer than 30 days requires stor- age maintenance. Unless the storage instructions are fol- lowed, fuel remaining in the carburetor will evaporate, leav- ing gum-like deposits. This could lead to difficult starting and result in costly repairs.

1.Remove the fuel tank cap slowly to release any pres- sure 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 combus- tion chamber. Pull starter rope slowly several times to coat internal components. Replace spark plug (Figure 7-7A).

NOTE: Store the unit in a dry place and away from possi- ble sources of ignition such as a furnace, gas hot water heater, gas dryer, etc.
