(4) "Excessively worn" means worn close to or beyond serviceable limits, condition likely to result in a failure if
replacement of the affected parts is not made before the next scheduled inspection.
b. Reporting Deficiencies. The operator will report all deficiencies on DD Form 110.
c. Before-Operation Services. The following services will be performed to determine if the condition of the
equipment has changed since it was last operated, and to make sure the equipment is ready for operation. Any
deficiencies must be corrected or reported to the proper authorities before the unit is put into operation.
(1) Mounting. Check the mounting of the engine compressor on the truck to make certain that it is secure.
(2) Fuel. Check fuel supply. See that the fuel tank is full. Check reserve supply of fuel and replenish if
necessary.
(3) Coolant. Check coolant level in radiator and see that it is up to proper level. When filling cold radiators,
allow room for expansion.
(4) Lubrication. Check oil level in engine crankcase. Add oil if necessary.
(5) Leaks, general. Check for leaks, paying particular attention to the cooling system, oil and fuel lines and
connections, and for signs of leaks under the unit.
(6) Visual inspection. Make a general check of the entire unit for cracked or broken parts and loose or missing
bolts. Before starting the unit, check the operation of all controls.
(7) Starting precautions. Make certain that the receiver service valves are open before attempting to start the
engine. Check to see that the equipment is clear of tools and obstructions. Start engine and adjust equipment to proper
operating tempo. Drain the moisture in the air receiver by opening the two drains in the bottom of the tank. Blow the
condensation out of the pressure control lines by opening all air line drain cocks. Air line drain cocks are located at the No.
1 compressor cylinder head, at the shutterstat, at the shutterstat air filter, and at the slowdown assembly.
(8) Safety valve. Test the safety valve operation when the air receiver pressure gage reads 70 psi. Lift the
valve handle to pop the valve manually.
