OIL SPECIFICATIONS
Table below shows hydraulic oils recommended for equipment use. The most
suitable oil is selected in such a way that the temperature of the hydraulic oil in
continuous use is in the ideal area on the chart and the hydraulic system is used to
best advantage.
Problems due to incorrect hydraulic oil viscosity in the equipment:
Oil too thick
■
Difficult start up
■
Stiff operation
■
Danger of cavitation
■
Sticky valves
■
Filter bypass opens, impurities in the oil are not removed
Oil too thin
■
Efficiency losses (internal leaks)
■
Damage to gaskets and seals, leaks
■
Accelerated wearing of parts, because of decreased lubrication efficiency
■
Danger of cavitation
