ULTRAFLEX

3.6 Filling and purging

After the first installation and after maintenance operations it is necessary to fill the system with hydraulic oil.
This operation must avoid the air in the system, to ensure the good system operation. The hydraulic system must
be filled from the highest point of the system, which means from the upper steering station.
CAUTION
To avoid air bubbles in the oil, it is necessary to fill the tank slowly.
WARNING
The filling and bleeding operations must be carried out at least by two operators.
DANGER
Use ULTRAFLEX oil or other compatible oils.
Hydraulic oil OL150 has been specifically formulated for ULTRAFLEX to ensure high quality performance level of
ULTRAFLEX products throughout time.
Its special "Zinc Free" formula enhances protection against marine oxidation. The special mix of anti-wear and
stabilizing components of OL150 allow ensuring great results as far as the product duration and performances
are concerned in several environmental conditions.
ULTRAFLEX hydraulic oil complies with standard ISO 10592 concerning hydraulic steering systems. ULTRAFLEX is
not to be held responsible for any damages or performance deterioration if oils different from OL150 are used.
DANGER
Do NOT use ATF Dexron II transmission oils or brake oils which could cause the steering system seizing.
Oils which are compatible with OL150 ULTRAFLEX are:
- Shell Tellus T15 and Shell Tellus T22
- Mobil DTE 11M
NOTICE
ULTRAFLEX will not be able to ensure the compatibility of the above mentioned oils with OL150 if the oil manufac-
turers vary their formulation; in particular, it will not be able to ensure its compliance with standard ISO 10592
concerning hydraulic steering systems. Under no circumstances ULTRAFLEX is to be held responsible for any
damages or performance deterioration.
In the days after the filling, check the oil level; if necessary top off the system.
At the beginning the oil level can lower, as small amounts of air can be released in a homogeneous way.
DANGER
After 24 hours repeat the purging and check the absence of leaks.

3.6.1 Positioning of the oil bottle

The oil filling must be carried out by using the proper kit (including spout, flexible hose, fitting and pin) which is
NOT supplied.
- Remove the pump cap and insert the fitting.
- Attach the spout to a new bottle of hydraulic oil and connect the hose to the fitting and the bottle spout.
- Turn the bottle upside down and pierce it with the supplied pin, as shown in the picture, to ease the oil passage
towards the pump. Fill the pump until no air bubbles are visible in the hose.
