MAINTENANCE
5. Measure the plug gap with a spark plug gap gauge. The
gap should be 0.7 to 0.8 mm (0.028-0.031 in). Carefully
adjust the gap if necessary. See Fig. 15.
6. Screw the spark plug back into the spark plug hole us-
ing the spark plug wrench. Do not over-tighten spark plug.
Recommended tightening of the spark plug is ½ to ¾ of a
turn (15 ft-lb torque/20.33 Nm) after the spark plug gasket
contacts the spark plug hole.
7. Reinstall the spark plug boot over the spark plug.
DRAINING THE FUEL TANK
Drain and clean the fuel tank each year, or before storing
the generator for longer than two months.
1. Prepare an approved gasoline-storage container to collect
the drained fuel. Place it near the fuel valve (Fig. 16).
2. Turn the fuel valve to the OFF position.
3. Locate the fuel line between the fuel valve and the carbu-
retor. Disconnect the fuel line from the fuel valve.
NOTE: A small amount of fuel may leak from the fuel line
during removal.
4. Place a funnel below the fuel valve opening, and direct the
other end of the funnel over the prepared container.
5. Turn the fuel valve to the ON position to start draining the
fuel from the fuel valve opening. NOTE: The draining process
may take a few hours, depending on the amount of fuel in
your gas tank.
6. Once the fuel is completely drained, turn the fuel valve to
the OFF position.
7. Start and run the engine until the fuel runs out.
8. Drain the carburetor. Refer to "Draining The Carburetor."
CAUTION! Store the emptied gasoline in a suit-
able place. Never store fuel for more than 2
months.
