STORAGE
The water pump should be started at least once every
seven days and allowed to run at least 30 minutes. If this
cannot be done and you must store the unit for more than
30 days, use the following information as a guide to prepare
it for storage.
Long Term Storage Instructions
It is important to prevent gum deposits from forming in
essential fuel system parts, such as the carburetor, fuel filter,
fuel hose or tank during storage. Also, experience indicates
that alcohol-blended fuels (called gasohol, ethanol or
methanol) can attract moisture, which leads to separation
and formation of acids during storage. Acidic fuel can
damage the fuel system of an engine while in storage.
Fuel Additive:
If adding a fuel additive, fill the fuel tank with fresh fuel. If
only partially filled, air in the tank will promote fuel
deterioration during storage. Engine and fuel can be stored
up to 24 months with additive.
• Add fuel additive following manufacturer’s instructions.
• Run the engine outdoors for 30 seconds to be sure that
treated fuel has replaced the untreated fuel in the
carburetor.
If fuel additive is not used, remove all fuel from tank and
run engine until it stops from lack of fuel.
Change Oil
While engine is still warm, drain oil from crankcase. Refill
with recommended grade.
Oil Cylinder Bore
• Remove spark plug and pour about 1 ounce (30ml) of
clean engine oil into the cylinder.
• Install spark plug and pull starter handle slowly to
distribute oil.
Water Pump
1. Drain water pump as described in “Drain and Flush
Water Pump”.
2. Clean water pump as described in “Cleaning”.
3. Check that openings on water pump are open and
unobstructed.
Other Storage Tips
1. DO NOT store fuel from one season to another.
2. Replace fuel can if it starts to rust. Contaminated fuel
will cause engine problems.
3. If possible, store unit indoors and cover it to give
protection from dust and dirt. BE SURE TO EMPTY
FUEL TANK.
4. Cover unit with a suitable protective cover that does
not retain moisture.
5. Store water pump in clean, dry area.
WHEN STORING FUEL OR EQUIPMENT WITH FUEL
IN TANK
• Store away from furnaces, stoves, water heaters, clothes
dryers or other appliances that have pilot light or other
ignition source because they can ignite fuel vapors.
WHEN DRAINING FUEL
• Turn water pump OFF and let it cool at least 2 minutes
before removing fuel cap. Loosen cap slowly to relieve
pressure in tank.
• Drain fuel tank outdoors.
• Keep fuel away from sparks, open flames, pilot lights, heat, and
other ignition sources.
• DO NOT light a cigarette or smoke.
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or
death.
WARNING
• NEVER pull starter handle with spark plug removed.
Unintentional sparking can result in fire or
electric shock.
WARNING
• DO NOT place a storage cover over a hot water pump.
• Let equipment cool for a sufficient time before placing the
cover on the equipment.
Storage covers can be flammable.
