9.5 Changing the hydraulic oil
Change hydraulic oil at least once in two years. Forest crane hydraulic system has been
filled with Addinol HVLP ISO VG. 32 (DIN 51524/3) hydraulic oil at the factory. Oil
temperature should not exceed 75°C in summer, winter oil can be used all year round.
We recommend to use high pressure oil filter with indicator (which shows, when filter
element is dirty and needs to be changed).
9.6 Hydraulic oil requirements
 Freezing point must be below -50C.
 Viscosity must not be lower than 1.5 E, +50C for piston pumps and 2.5 E°,
+ 50°C for gear pumps.
 Hydraulic oil must contain the necessary additives for lubrication, rust
protection and defoaming.
