STORING, TRANSPORTING, OR SHIP- PING

NOTE: If shipping, transport companies require fuel tanks to be empty.

1. Drain fuel tank.

NOTE: This model has a drain plug on underside of fuel tank. Remove drain plug to drain all fuel. Be sure all fuel is removed.

2. Replace drain plug.

3. If any debris is noted in old fuel, add 1

or 2 quarts of clean kerosene to tank,

stir, and drain again. This will prevent

excess debris from clogging filters

during future use.

Properly dispose of old and dirty fuel.

Check with local automotive service

stations that recycle oil.
