3.6.1 Positioning of the oil bottle
- Remove the pump cap and insert the fittings.
- Attach the spout to a new bottle of hydraulic oil and connect the hose
to the fittings 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.

While replacing the oil bottle, during the filling process, close all the bleed
valves on the cylinder/s. To bleed the system, check that oil is always present
in the filling hose. If some air is in the system during the bleeding process,
the whole bleeding process must be started again.
WARNING
Replace the bottle before it empties and use recovered oil only after 24
hours.
CAUTION
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
WARNING
To avoid air bubbles in the oil, it is necessary to fill the tank slowly.
The filling and bleeding operations must be carried out at least by two operators.
DANGER
Use
UFLEX
oil or other compatible oils.
Hydraulic oil OIL15 has been specifically formulated for
UFLEX
to ensure high quality performance level of
UFLEX
products throughout time.
The special mix of anti-wear and stabilizing components of OIL15 allow ensuring great results as far as the
product duration and performances are concerned in several environmental conditions.
UFLEX
is not to be
held responsible for any damages or performance deterioration if oils different from OIL15 are used.
Do NOT use ATF Dexron II transmission oils or brake oils which could cause the steering system seizing.
Oils which are compatible with OIL15
UFLEX
are:
- Shell Tellus T15 and Shell Tellus T22
- Mobil DTE 11M
DANGER
UFLEX
will not be able to ensure the compatibility of the above mentioned oils with OIL15 if the oil
manufacturers vary their formulation. Under no circumstances
UFLEX
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.
