OFF SEASON STORAGE

If the machine is to be inoperative for a period

ionger than 30 days, the foiiowing procedures are

recommended:

1. Working outdoors, drain ail fuel from the fuel

tank. Use a clean dry cloth to absorb the small

amount of fuel remaining in the tank. Then run

the engine until all fuel in the carburetor is ex

hausted.

WARNING

Do not drain fuel while smoking, or

if near an open fire.

2. Drain all the oil from the crankcase (this

should be done after the engine has been

operated and is still warm). Refill the

crankcase with clean new oil.

3. Disconnect the spark plug wire and remove

the spark plug from the cylinder. Pour about 2

or 3 tablespoons of engine oil into the

cylinder. Turn the engine over several times to

spread out the oil. Replace the spark plug, but

do not connect the wire.

4. Clean the engine and the entire mower

thoroughly.
