Personal injury can result from hydraulic oil pressure and hot oil. Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system. Make sure all of the attachments have been lowered, oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. |

Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide", for tools and supplies suitable to collect and contain fluids in Caterpillar machines. Dispose of all fluids according to local regulations and mandates. |

Troubleshooting can be complex. A list of some of the possible problems and corrections are on the following pages.
This list of possible problems and possible corrections will only provide an indication of the location of a problem and the repairs that are required. Remember that a problem is not necessarily caused by one part, but by the relation of one part with the other parts. This list can not provide all possible problems and corrections. Service personnel must find the problem and the source of the problem. Then, complete the necessary repairs.
Perform a visual inspection first. If the visual checks are completed but the problem has not been identified, perform operational checks. If the problem is not understood, perform instrument tests. This procedure will help identify problems in the water system.
