HOSE AS-COOLANT 4696250 - Caterpillar

Removal Procedure
Start By:
Place the harvester head in the VERTICAL position. Secure the harvester head frame to the yoke with a suitable chain. Refer to Disassembly and Assembly, "Preparation for Disassembly" for detailed instructions.
The harvester head frame may tip over when it is in the vertical position. Personal injury or death may result if this occurs. Secure the frame to the yoke with a chain or similar restraint prior to working on the harvester head.
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 work tools have been lowered to the ground, and the 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 product. 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 on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
Note: Put identification on all lines, on all hoses, on all wires, and on all tubes for installation purposes. Plug all lines, hoses, and tubes. This helps to prevent fluid loss and this helps to keep contaminants from entering the system.
