Installation and Maintenance Manual
3.8 General recommendation
It is very important to check the absence of air in the system before using the boat! We recommend trying
to manually move the engine/s or the helm/s towards port and starboard, making sure that there is no
movement of the cylinder body on the main cylinder shaft.
If the cylinder body moves too much, there is still air in the system. The air presence in the system can
cause bad responses to the controls and so it can cause damage, injuries or death.
WARNING
3.7.2 Purging procedure
3.7.1 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 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 "T" fittings of 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.
WARNING
NOTICE
Carry out the purging procedure as indicated in the installation and maintenance manual of the cylinder
used. Then check that the oil level is suitable by turning 1/2 turn the steering wheel and by making the oil
come out of the bleed valve. Close the valve and check the system.

DANGER
After 24 hours repeat the purging and make sure there are no leaks.
WARNING

To carry out this operation, it is necessary to use the oil filling kit (1 needle,
1 transparent pipe, 1 pipe connection and 1 spout for the oil bottle). This kit
is NOT supplied.
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.
