Engines Cold Start Manifold Heater must still be capable of operation in warmer climates without extensive changes. WARNING The following information is provided to engine owners, operators, and maintenance personnel on how the modifications can be applied to get satisfactory perfor- mance from their diesel engines. Do not use starting fluid on an engine equipped with a manifold heater. Using starting fluid could cause an explosion, possibly resulting in severe personal injury and engine damage. There are three basic objectives: 1. Reasonable starting characteristics followed by practical and dependable warm-up of the engine and equipment. Turn the ignition switch to the ON position.
If the tem- perature is below 32°F (0°C), the wait-to-start indicator will come on while the manifold heater warms up. After the indicator light goes out, start the engine. Run the engine slightly above idle until oil pressure shows on the gauge. If oil pressure doesn’t show on the gauge within 30 seconds of starting, turn the key to the OFF position and wait 1 minute; then repeat the starting pro- cedure. 2. A unit or installation which is as independent as possible from external influences. 3. Modifications which maintain satisfactory operating temperatures with a minimum increase in mainte- nance of the equipment and accessories.
If satisfactory engine temperature is not maintained, higher maintenance cost will result, due to increased engine wear. Cold Weather Operation Cummins Engines Special provisions to overcome low temperatures are definitely necessary, whereas a change to a warmer climate normally requires only a minimum of revision. Most of the accessories should be designed in such a way that they can be disconnected so there is little ef- fect on the engine when they are not in use. Satisfactory performance of a diesel engine operating in low ambient temperatures requires modification of the engine, surrounding equipment, operating practices, and maintenance procedures.
The lower the tempera- tures the greater the amount of modification required, and yet, with the modifications applied, the engines 4.3
