CYLINDER GP-BOOM 9T5222 - Caterpillar

Indicators and Gauges
Tachometer (1) - Indicates the engine revolutions per minute (rpm) in hundreds. The normal operating (GREEN) range is 1200 to 2200 rpm. Converter and Retarder Temperature Gauge (2) - Indicates the torque converter and retarder oil temperature. The gauge should be in the GREEN range during operation. Low Air System Pressure Light (Red) - When it lights, it indicates that air pressure in the reservoirs is low. Below 415 kPa (60 psi) the light should go on and the electric warning horn should sound. Engine Coolant Temperature Gauge (1) - The gauge should register in the green range during operation. Air System Pressure Gauge (2) - Indicates the air pressure in the reservoirs. The gauge should register in the GREEN range during operation. Service Meter (3) - Indicates the total service hours on the engine. Use it to determine service intervals. Engine Oil Pressure Gauge (4) - The gauge should register in the WHITE range at low idle engine speed, or in the GREEN range at operating speed. Ammeter (5) - Indicates the condition of the battery charging circuit. The gauge should read ZERO soon after the engine starts.Switches
Battery Disconnect Switch - To activate the electrical system, insert the key and turn the switch to the right. When parking the machine, turn the switch to the left to open the electrical circuit, and remove the key. This will prevent battery drain.
