8. Maintenance
Hydraulic safety
Make sure that all components in the hydraulic
system are kept in good condition and are clean.
Carry out the maintenance of the hydraulic parts
on a clean place, free from dust or contaminants.
Otherwise, there may have malfunction or premature
wear on the equipment.
The correct operation and maintenance of the
hydraulic system will prevent damages, air infiltration
on the system, oil and system overheating, damages to
the rubber components, etc.
Periodically or when the oil is replaced anormally or even when there is loss of power,
inspect the hydraulic system, fasten the connections that are leaking, replace the hoses that
are almost reaching its expiration date or if they show any cut, crack or dryness. Regarding
the hoses assembly, do it in a way that they always can flex, without twisting or pulling it.
If there is any problem with the hydraulic cylinder, do not carry out any maintenance
procedure or weld heating, as both of this may cause roundness on the barrel or other
problems, consequently leading to internal leakages, lack of power, gripping, damages to
the cylinder rods, etc.
Do not attempt any makeshift repairs to the hydraulic lines, fittings or hoses
by using tape, clamps or cements. The hydraulic system operates under extremely
high-pressure. Such repairs will fall suddenly and create a hazardous and unsafe
condition. A serious accident or even death may occur.
Wear proper hand and eye protection when searching for a high-pressure hydraulic
leak. Use a piece of wood or cardboard as a backstop instead of hands to isolate and
identify a leak.
If injured by a concentrated high-pressure stream of hydraulic fluid, seek medical
attention immediately. Serious infection or toxic reaction can develop from hydraulic
fluid piercing the skin surface. If this doctor is not aware of this type of problem, ask
for a reference or look for another one to find the proper treatment.
Before applying pressure to the system, make sure all
components are tight and that lines, hoses and coupling are
not damaged.
Carry out the operations on a carefully and controlled
manner. Avoid to let the hydraulic system working when
it is not being used.
Failure to follow these procedures may lead to fatal
accidents or even death.
