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. 24.
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 selector switch (Fig.
25 - 1).
2. Turn the fuel selector switch to the PROPANE position.
3. Locate the fuel line between the fuel selector switch and
the carburetor. Disconnect the fuel line from the fuel selector
switch.
NOTE: A small amount of fuel may leak from the fuel line
during removal.
4. Place a funnel below the fuel selector switch opening, and
direct the other end of the funnel over the prepared con-
tainer.
5. Turn the fuel selector switch to the GASOLINE position to
start draining the fuel from the fuel selector switch opening.
NOTE: The draining process may take a few hours, depend-
ing on the amount of fuel in your gas tank.
6. Once the fuel is completely drained, turn the fuel selector
switch to the PROPANE 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.
