Safety Requirements
The instructions provided with this manual are for installation and use only. The Harken Power Unit must only be serviced by
a qualified hydraulic technician. For repair service, contact Harken to find the repair site nearest you.
• Always wear eye protection.
• Make sure all components are rated for the maximum system pressure. Hose and fittings generally have a 4:1 safety factor.
In static applications, these safety factors are normally reduced to 2:1. Special care should be used in selecting the proper
products for these systems. There is a correlation between cost of components and their quality.
• Do not exceed equipment ratings. Overloading causes equipment failure and possible personal injury.
• Never set the relief valve pressure higher than the maximum rated pump pressure. Doing so may result in equipment damage
and/or personal injury.
• System operating pressure must not exceed the pressure rating of the lowest rated component in the system. If in question,
install pressure gauges in the system to monitor operating pressure. They are your window to what is happening in the system.
• Keep hydraulic equipment away from flames and heat. Excessive heat will soften packings and seals, resulting in oil leaks.
Heat also weakens hose materials and packings. For optimum performance, do not expose equipment to temperatures of
65°C [150°F] or higher.
• Use caution when searching for leaks, cracks, kinks or other damage. Serious injury can occur to hands or face from
pressure build-up or heated fluids.
• Do not handle pressurized hoses. Escaping oil under pressure can penetrate the skin, causing serious injury. If oil is
injected under the skin, seek immediate medical attention.
• Relieve system pressure before servicing or replacing hose line.
• Never remove a hose line from a pressurized motor or cylinder.
• Avoid hydraulic hose damage. 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.
• Route hose assemblies so that all bends are directed away from the operator.
• 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.
• Do not lift hydraulic equipment by the hoses or swivel couplers. Use the carrying handle or other means of safe transport.
WARNING! Strictly follow all instructions to avoid an accident, damage to your vessel, personal injury or death.

DANGER! Hydraulic equipment under pressure may cause serious injury or death.
