2) 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
Pull all circuit breakers and/or disconnect battery negative terminal.
(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 (Hobart Part No. 76A1354-001) are available for use 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 about two minutes so that all internal engine components will be
coated with new oil.
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 pressures.
