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
NOTICE
The filling and purging operations can be facilitated by using the automatic purging equipment BUBBLE
BUSTER (supplied separately).
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
manufacturers 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.
According to the types of installation, it is necessary to carry out the different bleeding procedures, as it follows.
