MAINTENANCE
DRAINING THE FLOAT BOWL
1. Remove the engine service cover.
2. Locate the drain hose extending from the bottom of the
carburetor float bowl.
3. Place the loose end of the hose outside the generator
into an approved gasoline container to catch the drained
fuel.
4. Loosen the float bowl drain screw and allow the fuel to
drain. Tighten the float bowl drain screw.
5. Route the drain hose between the air cleaner housing
and the engine service cover. Install the engine service
cover.
DRAINING THE FUEL TANK
If storing the generator for longer than six months, drain
the fuel tank to prevent fuel separation, deterioration, and
deposits in the fuel system.
1. Unscrew the fuel tank cap. Remove the fuel screen filter
by slightly compressing it while removing it from the
tank.

2. Using a commercially available gasoline hand pump
(not included), siphon the gasoline from the fuel tank
into an approved gasoline container. DO NOT use an
electric pump.
3. Reinstall the fuel screen filter and the fuel tank cap.
4. Start the generator and allow it to run until the generator
engine stops.
5. Place the RUN/STOP switch in the OFF position.
6. Remove the spark plug.
7. Put a teaspoon of engine oil into the cylinder and pull the
recoil handle until resistance is felt. At this position the
piston is coming up on its compression stroke and both
valves are closed. Storing the engine in this position will
help prevent internal corrosion. Return the recoil handle
gently.
8. Reinstall the spark plug. Leave the spark plug boot
disconnected to prevent accidental starting.
9. Install the engine service cover.

VALVE CLEARANCE

Checking and adjusting valve clearance must be done
when the engine is cold.
1. Remove the rocker arm cover and carefully remove
the gasket. If the gasket is torn or damaged, it must be
replaced.
2. Remove the spark plug so the engine can be rotated
more easily.
3. Rotate the engine to top dead center (TDC) by pulling
the recoil handle slowly. Looking through the spark plug
hole, the piston should be at the top (both valves are
closed).
4. Both the rocker arms should be loose at TDC on the
compression stroke. If they are not, rotate the engine
360°.
