SECTION 2. PREPARATION FOR USE, STORAGE, OR SHIPPING

1. Preparation for Use

A. Inspection/Check Inspect the unit thoroughly prior to operation.
(1) Remove blocking, banding, ties, and other securing material.
(2) Inspect exterior for shipping damage such broken lights, damaged sheet metal, etc.
(3) Open all canopy doors and inspect interior for foreign material such as rags, tools, shipping pa-
pers, etc.
(4) Check fuel, coolant, and oil hoses and connections for visible leaks. Visually inspect the compart-
ment floor and ground surface under the unit for signs of leakage. If leaks are found, correct by tight-
ening hose clamps, tube fittings, etc., as required.
(5) Check the following for sufficient quantity:
(a) Fuel
Place engine permissive start switch (1-1; 15, Fig. 8) in the RUN position to energize fuel
gage when engine is stopped.
(b) Engine coolant
The radiator cap is accessible by opening the hinged access cover on the front canopy hous-
ing. Coolant level should be approximately one inch below the filler neck. Allow a capacity for
coolant expansion.
CAUTION: Be sure the cooling system antifreeze solution is adequate to protect below lowest
temperature expected.
NOTE: For antifreeze protection, use a solution of 50% permanent antifreeze (Ethylene glycol)
and 50% clean water.
(c) Engine lubricating oil
Oil level should be at "FULL" mark on oil level gage rod. See the John Deere Shop Manual
for oil recommendations.
(6) Check air cleaner
The air cleaner (Sect. 1-1, Fig. 3, item 8) is a "dry" type. Be sure there are no papers, tapes, or
other material covering the air inlet area.
B. Installing Three-phase AC Output Cables
Units are generally shipped without generator set-to-aircraft cables. The load contactor, at which ca-
bles must be connected is located on the left side of the unit beside the engine control panel (see 1-1;
2, Fig. 3) . To install AC output cables proceed as follows.
(1) Open and raise left rear canopy door of the generator set.
(2) Loosen screws on cable clamp located on the cable tray on the left side of the generator set.
(3) Remove lexan cover over the load contactor.
(4) Route cables through cable clamp, and up to the load side (bottom) of the load contactor.
