VICE SECTION Before servicing this tool it is important to understand how this tool operates While being verv simple understanding the principles of operation and their interaction will assist vou to maintain the tool to optimum working efficiencv Fault diagnosis and repair will also be greativ simplified PRINCIPLE OF OPERATION Cutting Cvcle Operating valves are depressed supplying a positive air pressure signal to the pilot of the power pack control board The pilot pressure shuttles the control valve allowing main supply air pressure to operate the power pack hydraulic valve The hydraulic valve opens and hydraulic pressure is transmitted to the rear port of the hand tool via the hydraulic hose This hydraulic pressure then acts on the piston rod assembly in the hand tool and causes the piston rod assembly to move The movement of the piston rod assembly is now transmitted to the blades via cam links and the blades close Hydraulic pressure will build to 150 bar 2200 PSI as soon as cutting pressure is exerted causing the blades to cut through the animal s appendage Opening Cycle Operating valves are released allowing the positive air pressure signal to vent through the valve exhaust port The pilot pressure shuttles the control valve allowing main supply air pressure to operate the power pack hydraulic valve closing side The hydraulic valve opens and hydraulic pressure is transmitted to the front port of the han
