3.6. Lubrication and Maintenance Operations
Fill the hydraulic circuit:
Fill with the filling device of the following parameters: •
Min pressure 6 MPa (870 PSI)
Filtering property 3 to 10 µm
Slip the filling device quick-coupling (1) over the quick-cou-
(1) over the quick-cou- over the quick-cou- •
pler.
Fill the hydraulic circuit until clean oil starts to flow out from
•
the drain plug.
After approximately 15 l (4 gal US) flow out, mount the drain
•
plug.
Top up the tank with oil its max level and disconnect the
•
filling device.
Spare filling via tank filler neck (2):
Carry out hydraulic circuit filling via the
filler neck in emergency cases only!
This filling method will need to reduce
the next exchange interval by one half,
i.e. 1000 hours or 1 year.
Tank filler neck plug has been sealed. When this seal is bro- •
ken during guarantee period then the guarantee will termi-
nate.
Fill the tank through its filler neck with the required type of
•
oil up to the bottom of a strainer inside the filler neck.
Note
When filling through the tank filler neck a large portion of •
old oil will remain in the circuit along with the impurities,
and the life of hydraulic units will lower.
You may order the filling device with the Machine manufac-
•
turer or a dealer.
When the circuit is filled, please check the hydraulic oil level indicator lamp is not ON.
Start the engine and test the Machine functions at the increased RPM so to fill the circuits.
Check the filter tightness, temperature sensors, inlet pipes and lids.
Observe cleanliness at work. Prevent any contamination of the system with the materials that might
cause damage to the major units!
Follow the fire precautions!
Do not open uselessly the hydraulic tank!
Exchange oil and filter element always when destruction of the inner parts of the units (hydraulic mo-
tors, hydroelectric generators) occurs, or following a major repair of the hydraulic system. Clean and
flush the hydraulic tank before new unit is installed. Replace filter element.
Never use chemical cleaning agents to clean the tank.
To clean, please use cleaners with no fibre let-off.
Refill oil according to the Section 3.2.4.
