4. Maintenance

4.1 Replacing the oil

When replacing the oil or after maintenance, make sure no air is trapped
in the hydraulic system. This should be checked before pressurizing the
injector. Only use clean, recommended hydraulic oils. Do not mix luids or
oils of different brands

4.2 Oil cleanliness and leakage

Dirt and metal particles in the oil can cause wear of the piston mating
surfaces, leading to excessive oil leakage and irreparable damage to the
oil injector.
The recommended oil cleanliness level should be meet or exceed
ISO 4406:1999 20/18/15.
Using luids, other than oils or SKF mounting and dismounting luids, can
cause corrosion and/or damage to the piston mating surfaces.
A small amount of oil leakage between the piston mating surfaces is
expected at high oil pressures. This small leakage helps ensure that the
piston is kept lubricated.
