When you are using hydraulic cylinders and puller studs, always ensure that the rated capacity of the puller stud meets or exceeds the rated capacity of the hydraulic cylinder. If the puller stud does not meet or exceed the rated capacity of the hydraulic cylinder, a sudden failure of the puller stud could occur. The sudden failure of the puller stud could result in personal injury or death. |

High hydraulic pressure hazard. This machine will not automatically release hydraulic oil pressure from the hydraulic system after the engine has been stopped. Hydraulic system pressure will not be released by use of operator controls. Hydraulic oil pressure can remain in the system for a time after the engine has stopped. Personal injury or death may result from the release of hydraulic oil pressure, the release of hot oil, or parts separating with force if proper care is not used during the disassembly. Use extreme caution at all times when servicing this machine or any of the components. Park the machine on a level surface and lower all implements to the ground. Sudden movement of the machine or the release of oil under pressure can cause injury or death to persons on or near the machine. Allow all fluids to cool prior to performing any service work. Take appropriate precautions to ensure safety from any remaining pressure. |

Cylinders equipped with lock valves can remain pressurized for very long periods of time, even with the hoses removed. Failure to relieve pressure before removing a lock valve or disassembling a cylinder can result in personal injury or death. Ensure all pressure is relieved before removing a lock valve or disassembling a cylinder. |
