DANGER: To avoid personal injury, keep hands and feet away from cylinder and work-piece during operation.
WARNING: Do not exceed equipment ratings. Never attempt to lift a load weighing more than the capacity of the
cylinder. Overloading causes equipment failure and possible personal injury. The cylinders are designed for a
maximum pressure of 10,000 PSI (700kg/cm
). Do not connect a jack or cylinder to a pump with a higher pressure
2
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 in
the system. Install pressure gauges in the system to monitor operating pressure. It is your window to what is
happening in the system.
CAUTION: Avoid damaging hydraulic hose. Avoid sharp bends and kinks when routing hydraulic hoses. Using a
bent or kinked hose will cause severe back-pressure. Sharp bends and kinks will internally damage the hose, leading
to premature hose failure.
Do not drop heavy objects on hose. A sharp impact may cause internal damage to hose wire strands. Applying
pressure 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 means
of safe transport.
CAUTION: Keep hydraulic equipment away from flames and heat. Excessive heat will soften seals, resulting in fluid
leaks. Heat also weakens hose materials. For optimum performance do not expose equipment to temperatures of
65° C (170° F) or higher. Protect hoses and cylinders from weld spatter.
DANGER: Do not handle pressurized hoses. Escaping oil under pressure can penetrate the skin, causing serious
injury. If oil is injected under the skin, see a doctor immediately.
DANGER: Only use hydraulic cylinders in a coupled system. Never use a cylinder with unconnected couplers. If the
cylinder becomes severely overloaded, components can fail catastrophically causing severe personal injury or death.
