Removal Procedure
Use the following procedure to release the pressure in the hydraulic system:
Shut off the engine.
Move the control lever through the full travel. This will relieve any pressure that may be present in the pilot system.
Slowly loosen the breather cap on the hydraulic tank in order to release the pressure.
Tighten the breather cap on the hydraulic oil tank.
The pressure in the hydraulic system has now been released. Lines and components can now be removed. Note: Cap all the lines and plug all the lines after disassembly. Identify each line for assembly purposes.
Remove the bolts and open the radiator grill. Use the stops in order to keep the grill open.
