Preparation For Storage; General; Temporary Storage; Long Time Storage (Over 30 Days) - Hobart 140GT17P Operation And Maintenance Manual With Illustrated Parts List

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
(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 are available for use where excessive dampness is a problem, how-
ever the unit must be completely packaged and sealed if moisture absorbing chemicals are to be ef-
fective.
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 Sect. 2-1. This will include chang-
ing 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 tem-
peratures expected during the storage period. See 2-1; Para. 6, D. Be sure the solution is thoroughly
mixed.
(4) Clean the exterior of the engine with fuel oil. Dry with clean rags and compressed air.
(5) Seal all engine openings. Use a waterproof, vaporproof material which is strong enough to resist
puncture damage from air pressures.
C. Long Time Storage (Over 30 Days)
(1) The unit may be stored for long periods with no special preparation if it is possible to operate the
engine once each week.
(a) Make certain the cooling system is adequately protected.
(b) Start the engine and operate at a fast idle (800 to 1000 RPM) until coolant temperature has
reached at least 140 deg F.
WARNING: MAKE CERTAIN OF ADEQUATE VENTILATION BEFORE START-
ING THE ENGINE.
(c) Operate normal operating controls.
(2) If weekly operation is not possible, prepare and protect the engine in accordance with instructions
in John Deere Operator's Manual.
(3) To protect the generator and other electrical components, the complete unit should be packaged,
using moisture proof packaging and sealing material. Place containers of moisture absorbing chemi-
cals, such as silica-gel, in the unit before packaging.
