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.

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.
