Safety and General Maintenance

Important Receiving Instructions

Visually inspect all components for shipping damage. Shipping damage is not covered by warranty. If shipping damage 
is found, notify the carrier at once. The carrier is responsible for all repair and replacement costs resulting from damage 
during shipment. 

Safety

Prior to use, read all instructions, warnings and cautions carefully. Follow all safety precautions to avoid personal injury 
or property damage during system operation. Parker cannot be held responsible for damage or injury resulting from 
unsafe product use, lack of maintenance or incorrect product and/or system operation.

Contact Parker when in doubt as to the safety precautions and operations. If you have never been trained on high-
pressure hydraulic safety, consult your distribution or service centre for a hydraulic safety course.

Failure to comply with the following cautions and warnings could cause equipment damage and personal injury.

A CAUTION is used to indicate correct operating or maintenance procedures and practices to prevent damage to, or 
destruction of equipment or other property.

A WARNING indicates a potential danger that requires correct procedures or practices to avoid personal injury.

A DANGER is only used when your action or lack of action may cause serious injury or even death.

Pressure

WARNING: Do not exceed equipment ratings. Never attempt to assemble a product with an assembly load higher 
than the capacity of the tool assembly. Overloading causes equipment failure and possible personal injury. The tool 
assemblies are designed for a maximum pressure of 10,000 psi (700 bar). Do not connect a tool to a pump with a 
higher pressure rating.

WARNING: Whenever using hydraulic equipment, personal protective equipment (PPE), including eye protection, hard 
hat, gloves, and steel toe boots, should be utilized.

DANGER: Never set the pump/system relief valve to a higher pressure than the maximum rated pressure of the tool. 
Higher settings may result in equipment damage and/or personal injury. Do not remove the relief valve.

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. Recalibrate these pressure gauges 
as per supplier recommendations. Surge pressures or peak transient pressures in the system must be below the 
published maximum working pressure. Surge pressures and peak pressures can usually only be determined by 
sensitive electrical instrumentation that measures and indicates pressures at millisecond intervals. Mechanical pressure 
gauges indicate only average pressures and cannot be used to determine surge pressures or peak transient pressures. 
Published burst pressure ratings for hose assemblies is for manufacturing test purposes only and is no indication that 
the hose assemblies can be used in applications at the burst pressure or otherwise above the published maximum 
recommended working pressure.

DANGER: DO NOT HANDLE PRESSURISED HOSES. Escaping oil under pressure can penetrate the skin, causing 
serious injury. If oil is injected under the skin, see a doctor immediately.

Temperature

CAUTION: KEEP HYDRAULIC EQUIPMENT AWAY FROM FLAMES AND HEAT. Excessive heat will soften packings 
and seals, resulting in fluid leaks. Heat also weakens hose materials and packings. Be certain that fluid and ambient 
temperatures, both steady and transient, do not exceed 60°C [140°F], or fall below -20°C [-4°F]. Temperatures below 
and above the recommended limit can degrade hose and seals to a point where a failure may occur and release fluid.
