3.6. Lubrication and Maintenance Operations
Fill the hydraulic circuit:
Fill with the lling device of the following parameters:•
Min pressure 6 MPa (870 PSI)
Filtering property 3 to 10 µm
Slip the lling 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 ow out from •
the drain plug.
After approximately 15 l (4 gal US) ow out, mount the drain •
plug.
Top up the tank with oil its max level and disconnect the •
lling device.
Spare lling via tank ller neck (2):
Carry out hydraulic circuit lling via the
ller neck in emergency cases only!
This lling method will need to reduce
the next exchange interval by one half,
i.e. 1000 hours or 1 year.
Tank ller 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 ller neck with the required type of •
oil up to the bottom of a strainer inside the ller neck.
Note
When lling through the tank ller 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 lling device with the Machine manufac-•
turer or a dealer.
When the circuit is lled, 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 ll the circuits.
Check the lter 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 re precautions!
Do not open uselessly the hydraulic tank!
Exchange oil and lter 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
ush the hydraulic tank before new unit is installed. Replace lter element.
Never use chemical cleaning agents to clean the tank.
To clean, please use cleaners with no bre let-o.
Rell oil according to the Section 3.2.4.
