Important Safety Information Most accidents involving product operation, maintenance and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills and tools to perform these functions properly.

Hydraulic Control Valves Removal and Install ation 5 WARNING 3 Hydraulic oil under pressure can remain in the hydraulic system after the engine and pump have been stopped. Personal injury can result if the pressure is not released before any work is done to the hydraulic system. To prevent possible personal injury, turn the engine off and move the control levers to make sure the hydraulic pressure is released before any fitting, plug, hose or component is loosened, tightened, removed or adjusted.
Disassembly of Hydraulic Control Valve Start By : a. Remove hydraulic control valve. NOTICE : For the sake of convenience in assembly, put an identification mark on all valves. Cover the all openings with plug to protect from dirt and dust. 2. Release the bolt (4) and take apart the valve sections. 3. Release the screw (5) and separate return cap from valve. Then, remove the spool from the valve in downward direction (cap side). 1.
