PUMP GP-FUEL INJECTION 1597372 - Caterpillar

Keep engine speed low until the engine oil pressure registers on the gauge or the engine oil pressure indicator light goes out. If it does not register or the light does not go out within ten seconds, stop the engine and investigate the cause before starting again. Failure to do so, can cause engine damage.
Always run the engine at low idle for at least ten minutes before performing any other operations in cold conditions to protect your engine and to protect your transmission.
When you operate the machine in ambient temperatures below 4° C (40° F), cooler covers are recommended to maintain normal hydraulic operating temperatures. When the ambient temperature is above 4° C (40° F), the cooler covers are not required.
The engine may automatically change speeds when the machine is stationary and idling in cold ambient temperature for an extended time. The following conditions will be maintained:
Desired coolant temperature.
Desired operation of engine systems.
Desired operation of the regeneration system.During extended idling in cold ambient conditions, engine speed may operate between 1000 rpm and 1600 rpm. Operation at 1600 rpm is minimal and will only last for up to 20 minutes. The high exhaust system temperature indicator may also illuminate during extended idling conditions to signal that a low speed regeneration is in progress. A regeneration done in cold ambient extended idling conditions may activate below 30% soot level. A regeneration done in cold ambient extended idling conditions will typically last for 5-10 minutes.Look at the indicators and the gauges frequently during operation.Cycle all controls in order to allow warm hydraulic oil to circulate through all hydraulic cylinders and through all hydraulic lines.When the engine idles during warm-up, observe the following recommendations:
Allow the engine to warm up for approximately 15 minutes when the temperature is higher than 0°C (32°F).
Allow the engine to warm up for approximately 30 minutes or more when the temperature is below 0°C (32°F).
More time may be required if the temperature is less than −18°C (0°F). More time may also be required if the hydraulic functions are sluggish.In order to help the hydraulic components warm up faster, engage the implement controls and disengage the implement controls.
