10.2.1 Filter maintenance

Filters must be changed after the first 100 working hours and the second change is to
be carried out after 3 months or 500 working hours whichever is earlier. They must then
be changed at regular intervals of 6 months or 4000 working hours.

10.2.2 Oil maintenance

Hydraulic fluid

quick reference.

Analysis

It is recommended that the oil should be analysed every 6 months. The analysis should
cover viscosity, oxidation, water content, particle cunting possibly including element
analysis of particles.
Most oil suppliers are equipped to analyse the state of the oil and to recommend
appropriate action. The oil must be replaced immediately if the analysis shows that it is
exhausted.

Viscosity

Many hydraulic oils display viscosity loss with increasing use, and this means poorer
lubrication. The viscosity of the oil in service must never fall below the minimum
recommended viscosity.

Oxidation

Hydraulic oil oxidizes with time of use and temperature. This is indicated by changes in
colour and smell, increased acidity or the formation of sludge in the tank. The rate of

oxidation increases rapidly at surface temperatures above 60 °C (140 °F), and the oil

should then be checked more often.

The oxidation process increases the acidity of the fluid; the acidity is stated in terms of

the "neutralisation number". Typical oxidation is slow initially and increases rapidly later.
A sharp increase (by a factor of 2 and 3) in the neutralisation number between
inspections is a signal that the oil has oxidized too much and should be replaced
immediately.
