5.3.5 YEARLY ROUTINE SERVICING
5.3.5.1. Hydraulic Oil
Providing the hydraulic oil has been regularly maintained, it should only require changing at approximately two-
yearly intervals. This is dependent on maintenance, amount of use, application, temperature, atmospheric
conditions and other factors.
A cloudy appearance in the hydraulic oil indicates that water is present. A change from clear amber to dark
brown, accompanied by a strong “burnt” smell, indicates overheating of the oil. The cause should be investi-
gated and rectified. The presence of either requires a complete drain and refill of the entire hydraulic system.
Note: Always change the filter elements and clean the tank before refilling.
5.3.5.2. Hydraulic Oil Tank
Carefully check the condition of the oil inside the tank to ensure that it flows easily and is a clear amber colour.
In cases of gross contamination, it will be necessary to completely drain and refill the entire hydraulic system.
(See note above).
