Overloading causes equipment failure and possible personal injury.The tools are designed for a maximum pressure of 10,000 PSI (700kg/cm 2 ). Do not connect a tool to a pump with ahigher pressure rating. Never set the relief valve to a higher pressure than the maximum rated pressure of the pump.Higher settings may result in equipment damage and/or personal injury.WARNING: The system operating pressure must not exceed the pressure rating of the lowest rated component inthe system. Install pressure gauges in the system to monitor operating pressure. It is your window to what ishappening in the system.CAUTION: Avoid damaging hydraulic hose. Avoid sharp bends and kinks when routing hydraulic hoses. Using abent or kinked hose will cause severe back-pressure. Sharp bends and kinks will internally damage the hose, leadingto premature hose failure.Do not drop heavy objects on hose. A sharp impact may cause internal damage to hose wire strands. Applyingpressure to a damaged hose may cause it to rupture.IMPORTANT: Do not lift hydraulic equipment by the hose or swivel couplers. Use the carrying handle or other meansof safe transport.CAUTION: Keep hydraulic equipment away from flames and heat. Excessive heat will soften seals, resulting in fluidleaks. Heat also weakens hose materials. For optimum performance do not expose equipment to temperatures of65° C (170° F) or higher. Protect hoses and tools from weld spatter.DANGER: Do not handle pressurized hoses. Escaping oil under pressure can penetrate the skin, causing seriousinjury. If oil is injected under the skin, see a doctor immediately.DANGER: Only use hydraulic tools in a coupled system. Never use a tool with unconnected couplers.
