safety handbook for hydraulic oil

All oils are not alike. The correct oil will protect moving parts and will not damage seals. Using the wrong oil will damage your equipment and lead to malfunctions. Use Enerpac premium hydraulic oil. The most important oil characteristic is viscosity. Heat is also an important factor.

See the chart below for details.

Effects

Viscosity describes the ability of an
oil to flow. If the oil is too thin, there is
not enough lubrication. If the oil is too
thick, it will not flow fast enough to
perform as required.

High temperatures also cause seal
damage. In general, if the system is
too hot to touch, it is too hot to use.

REMEMBER: Always dispose of used oil properly. Observe local ordinances. Do not mix used hydraulic oil with other fluids.
