CLEANING THE GENERATOR
It is important to inspect and clean the generator before
every use.
Clean All Engine Air Inlet and Outlet Ports – Make
sure all engine air inlet and outlet ports are clean of any
dirt and debris to ensure the engine does not run hot.
Clean All Engine Cooling Fins – Use a damp rag and
a brush to loosen and remove all dirt on or around the
engine's cooling fins.
Clean All Alternator Cooling Air Inlets and Exhaust
Ports – Make sure the cooling air inlets and exhaust
ports of the alternator are free of any debris and ob-
structions. Use a vacuum cleaner to remove dirt and
debris stuck in the cooling air inlets and exhaust ports.
General Cleaning of the Generator – Use a damp rag
to clean all remaining surfaces.

STORING GENERATOR
Never store a generator with fuel in the tank
indoors or in a poorly ventilated area where the
fumes can come in contact with an ignition source
such as a: 1) pilot light of a stove, water heater,
clothes dryer or any other gas appliance; or 2)
spark from an electric appliance.
NOTICE
Gasoline stored for as little as 60 days can go bad, causing gum,
varnish and corrosive buildup in fuel lines, fuel passages and the
engine. This corrosive buildup restricts the flow of fuel, preventing
an engine from starting after a prolonged storage period.
Proper care should be taken to prepare the generator for
any storage.
1. Make sure the Engine Switch is switched to OFF so
the generator does not draw power from battery.
2. Clean the generator.
3. Drain all gasoline from the fuel tank as best as
possible.
4. With the fuel shut off valve open, start the engine
and allow the generator to run until all the remaining
gasoline in the fuel lines and carburetor is consumed
and the engine shuts off.
5. Close the fuel shut off valve.
6. Change the oil (see Changing Engine Oil on page
19).
7. Remove the spark plug (see Spark Plug Maintenance
on page 21) and place about 1 tablespoon of oil in
the spark plug opening. While placing a clean rag
over the spark plug opening, slowly pull there coil
handle to allow the engine to turn over several times.
This will distribute the oil and protect the cylinder
wall from corroding during storage.
8. Replace the spark plug (see Spark Plug Maintenance
on page 21).
9. Move the generator to a clean, dry place for storage.
