INTRODUCTION


When hydraulic oil has been swallowed, avoid vomiting,
but consult a doctor or go to a hospital.

If an accident occurs, see a doctor familiar with this type
of injury immediately.

Any fluid penetrating the skin must be removed within few
hours to avoid serious infections.

Flammable splashes may originate because of heating
near lines with fluids under pressure, resulting in serious
burns. Do not weld or use torches near lines containing
fluids or other flammable materials.
                                                                           TULI12WEX2013AA   9
Lines under pressure can accidentally be pierced when
the heat expands beyond the area immediately heated.

Arrange for temporary fire resistant shields to protect
hoses or other components during welding or torch use.

Have any visible leakage repaired immediately.

Discharged oil pollutes the environment. Soak up any
oil that has spilled with a proper binding agent. Sweep
up binding agent and dispose of it separately from other
waste.

Never search for leakages with fingers; instead, use a
piece of cardboard and always wear goggles.

Never repair a damaged line; always replace it. Replace
hydraulic hoses immediately on detecting any damaged
or moist areas.

Always store hydraulic oil in the original containers.


                                                 47768535C_EN 04/04/2017

INTRODUCTION


Hydraulic contamination
Contamination in the hydraulic system is a major cause of the malfunction of hydraulic components. Contamination
is any foreign material in the hydraulic oil.

Contamination can enter the hydraulic system in several ways:
• When you drain the oil or disconnect any line
• When you disassemble a component
• From normal wear of the hydraulic components
• From damaged seals or worn seals
• From a damaged component in the hydraulic system

All hydraulic systems operate with some contamination. The design of the components in this hydraulic system per-
mits efficient operation with a small amount of contamination. An increase in this amount of contamination can cause
problems in the hydraulic system.

The following list includes some of these problems:
• Cylinder rod seals that leak
• Control valve spools that do not return to neutral
• Movement of control valve spools is difficult
• Hydraulic oil that becomes too hot
• Pump gears, housing, and other parts that wear rapidly
• Relief valves or check valves held open by dirt
• Quick failure of components that have been repaired
• Slow cycle times are slow. The machine does not have enough power.

If your machine has any of these problems, check the hydraulic oil for contamination.

There are two types of contamination: microscopic and visible.

Microscopic contamination occurs when very fine particles of foreign material are suspended in the hydraulic oil.
These particles are too small to see or feel. Microscopic contamination can be found by identification of the following
problems or by testing in a laboratory.

Examples of problems caused by microscopic contamination:
• Cylinder rod seals that leak
• Control valve spools that do not return to neutral
• The hydraulic system has a high operating temperature

Visible contamination is foreign material that can be found by sight, touch, or odor. Visible contamination can cause
a sudden failure of components.

Examples of problems caused by visible contamination:
• Particles of metal or dirt in the oil
• Air in the oil
• Dark or thick oil
• Oil with an odor of burned oil
• Water in the oil

If you find contamination, use a portable filter to clean the hydraulic system.
