8.12 Examination and Repair of Hydraulic System
z
Lock the oil tank and other hydraulic equipment safely, release the pressure of all hydraulic
systems before examining the hydraulic system.
z
Never
bend or beat the high pressure hydraulic pipe.
Never
assemble the hard pipe and soft pipe
if they are bent abnormally or broken.
z
Routinely repair any loose or broken fuel oil circuits, lubricating oil circuits, the hard and soft
pipe of the hydraulic system. Leakage can cause fire, so routine maintenance is critical.
z
Examine the pipe system carefully (hard pipe and soft pipe), screw down the connectors
according to the proper torque. Do not examine a leak using your hand, rather use a board or
paper board. The leaking hydraulic liquid may penetrate your skin and cause death. If the liquid
splash onto your skin, the case of a physician trained for this kind of “burn” will be immediately
required.
z
Make sure all the pipe clamps, protective board, and anti-heat cover are installed properly to
prevent vibration and overheating due to friction with other parts.
z
Choose proper container to hold liquid when replacing the hydraulic oil of the hydraulic system
and when cleaning the parts. Please refer to
8.20 Waste Materials
in this chapter for the
methods to deal with waste liquid.
8.13 Preventing Fire
z
Stop the engine before adding fuel. Do not smoke and keep fire away while adding fuel.
