Omega Engineering JD 4045 manual Radiator Pressure CAP, Compressor OIL, Coolant Level, 17 P/N

COOLANT LEVEL

Before each start-up, when radiator is cold, the coolant should be checked. When needed, refill with a 50/ 50 solution of water and ethylene glycol, DO NOT use 100% antifreeze for “topping off”.

WARNING

CHECK THE COOLANT LEVEL ONLY WHEN THE ENGINE IS STOPPED AND THE TEMPERATURE IS BELOW 160ºF (70ºC) FAILURE TO DO SO CAN CAUSE PERSONAL INJURY FROM HEATED COOLANT SPRAY.

4.4 FAN

Check the fan for cracks, loose rivets, and bent or loose blades. Make sure it is securely mounted. Tighten the cap screws if loose. Replace damaged fans.

WARNING

NEVER USE THE FAN TO ROTATE THE ENGINE. THE BLADE(S) CAN BE DAMAGED CAUSINGAFAN FAILURE, WHICH CAN RESULT IN PERSONALINJURY OR PROPERTY DAMAGE.

4.5 RADIATOR PRESSURE CAP

If coolant continually spills from radiator through the overflow then the radiator cap should be tested and/ or replaced with a cap of the same pressure rating, generally 13 PSI. Be sure cap is turned to the proper secure position.

4.6 RADIATOR

Any sign of leakage from the radiator may justify a pressure test to assure its soundness. Radiator leaks should only be repaired by qualified service people. Dirt that clogs the cooling fins of the radiator should be removed. The use of an air stream of high-pressure steam cleaner should be done with caution so as to not damage the delicate fins. Bent cooling fins will reduce the cooling capability of the radiator.

4.7 COMPRESSOR OIL

The life and proper operation of the compressor is dependent on adequate and clean compressor oil. DEXRON® - III Automatic Transmission Fluid is supplied with the new machine and should be used for proper level maintenance and for oil changes. We recommend that you use DEXRON® - III Automatic Transmission Fluid.

WARNING

DO NOT REMOVE CAPS OR OTHER COMPONENTS WHEN COMPRESSOR IS RUNNING OR PRESSURIZED. BEFORE DOING SO, STOP COMPRESSOR AND RELIEVE ALL INTERNAL PRESSURE.
