ACTION REQUIRED
Replace the hydraulic lines listed in the Rework Procedure below. Caution: 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. 1. Park the machine on a level surface and lower all implements to the ground. Note: 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. 2. Replace the 395-9040 Hose Assembly with a new 395-5706 Hose Assembly in the 395-9320 Hydraulic Oil Cooler Lines Group. Refer to Image1. 3. Replace the 395-7969 Hose Assembly with a new 395-5707 Hose Assembly in the 395-9790 Swivel Lines Group. Refer to Image2. 4. Replace the 395-9039 Hose Assembly with a new 395-5708 Hose Assembly in the 395-9550 Return Lines Group. Refer to Image3. |
