PRECAUTIONS WITH HIGH PRESSURE LINE, TUBES AND HOSES
When inspecting or replacing high-pressure piping or hoses, check that the pressure has been released from
the circuit. Failure to release the pressure may lead to serious injury. Always do the following;
• Wear protective glasses and leather gloves.
• Fluid leaks from hydraulic hoses or pressurized components can be difficult to see but pressurized oil has
enough force to pierce the skin and cause serious injury. Always use a piece of wood or cardboard to
check for suspected hydraulic leaks. Never use your hands or expose your fingers.
• Do not bend high pressure lines. Do not strike high pressure lines. Do not install lines, tubes or hoses
that are bent or damaged.
• Make sure that all clamps, guards and heat shields are installed correctly to prevent vibration, rubbing
against other parts, and excessive heat during operation.
– If any of the following conditions are found, replace the part.
– Damage or leakage from hose end.
– Wear, damage, cutting of covering, or exposure of strengthening wire layer.
– Cover portion is swollen in places.
– There is twisting or crushing at movable parts of hose.
– Foreign material is embedded in the covering.
– Hose end is deformed.
OBTAIN IMMEDIATE MEDICAL ATTENTION IF PRESSURIZED OIL PIERCES SKIN.
Failure to obtain prompt medical assistance could result in gangrene or other serious damage to
tissue.
