Work carefully around an engine that is running. Engine parts that are hot, or parts that are moving, can cause personal injury. |
Low Idle Adjustment
Run the engine until the normal operating temperature is reached. Check the rpm at low idle . Use the adjustment screw (1) in order to adjust the low idle. Loosen the locknut and turn the screw clockwise in order to increase the rpm. Turn the adjustment screw counterclockwise in order to decrease the rpm.
Note: Refer to your Caterpillar Dealer for the correct rpm for low idle.
