Storage - Briggs & Stratton 73000 Operator's Manual

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.
WARNING
Fuel and its vapors are extremely flammable
and explosive.
Fire or explosion can cause severe burns or
death.
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.
Protect Fuel System
Fuel Stabilizer:
Follow these instructions if storing fuel more than 30 days.
To protect the fuel system from gum formation, use
Briggs & Stratton FRESH START™ fuel stabilizer plus.
If fuel stabilizer is used, you do not need to drain fuel
prior to storage.
• Run engine outdoors for several minutes to be sure
treated fuel has replaced untreated fuel in carburetor.
If fuel preserver is not used, then always 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. See "Changing Oil" on
page 16.
Oil Cylinder Bore
• Remove spark plug and pour about 1 teaspoon
(5 ml) of clean engine oil into the cylinder.
• Install spark plug and pull starter handle slowly
8-10 times to distribute oil.
WARNING
Unintentional sparking can result in fire or
electric shock.
• NEVER pull starter handle with spark plug removed.
Water Pump
1. Drain water pump as described in "Drain and
Flush Water Pump" .
2. Clean water pump as described in "Cleaning" .

unobstructed.
Other Storage Tips
1. DO NOT store fuel from one season to another
unless it has been treated as described in "Protect
Fuel System" .
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.
4. Cover unit with a suitable protective cover that
does not retain moisture.
