Preparation for Storage
When a generator set is to be stored or removed from operation, special precautions should be taken to
protect the internal and external parts from rust, corrosion, and gumming in the engine fuel system.
a) General
Open battery disconnect switch and then disconnect the battery negative terminal at the battery.
(1) The unit should be prepared for storage as soon as possible after being removed from service.
(2) The unit should be stored in a building which is dry and which may be heated during winter
months.
(3) Moisture-absorbing chemicals should be used where excessive dampness is a problem;
however, the unit must be completely packaged and sealed if moisture-absorbing chemicals are
to be effective.
b) Temporary
Storage
When storing the unit for 30 days or less, prepare as follows:
(1) Lubricate the unit completely in accordance with instructions in Section 2-2. This will include
changing engine oil, and all filter elements.
(2) Start the engine and operate for a minimum of two minutes so that all internal engine components
will be coated with new oil. (Note: if the unit is operated outside of the diagnostic mode, it will run
for 5 minutes in the cool down mode after the stop button is pressed.)
NOTE:
Do not drain the fuel system or crankcase after this run.
(3) Make certain the cooling system antifreeze solution is adequate to protect below the lowest
temperatures expected during the storage period. Be sure the solution is thoroughly mixed.
(4) Clean the exterior of the engine. Dry with clean rags and compressed air.
(5) Seal all engine openings. Use a waterproof, vapor proof material that is strong enough to resist
puncture damage from air pressure changes.
