SENSOR AS- 3156700 - 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.
Allow a cold engine to warm up at LOW IDLE for at least 5 minutes. Operate attachment controls in order to help speed the warm-up of the hydraulic components.
Look at the operator panels frequently during the operation of the machine. If any of the gauges do not function properly, stop the engine. Inspect the electrical system or the machine system in order to find the cause of the malfunctioning gauge. Perform necessary repairs prior to starting the machine again.
Test all the controls. Check the controls for proper operation.
