3.7.1 Positioning of the oil bottle
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.
- 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.
WARNING
While replacing the oil bottle, during the filling process, close all the bleed valves
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.
CAUTION
Replace the bottle before it empties and use recovered oil only after 24 hours.
3.7.2 Single steering station/ single cylinder
- Unscrew the two bleed valve protections and loosen 1.5 turns max. the nuts "A"
of the two bleed valves.
- Unscrew the two bleed valves and manually push the cylinder body to one side
until it stops as shown in picture 1.
- Position the oil bottle as explained in paragraph 3.7.1.
- Close the bleed valve on the cylinder end stroke side and put a purged oil tank
near the other bleed valve (as shown in picture 2).
- Turn the steering wheel slowly (as shown in picture 2) so that the oil can come
out of hoses,
NOTICE
Hold the cylinder body with the hand to prevent movements caused by the air present
in the cylinder chamber (picture 2).
- When the oil comes out of the bleed valve (without air bubbles), close the bleed
valve and continue to turn the steering wheel in the same direction to fill the cyl-
inder chamber (picture 3).
During this phase the cylinder body will move to the opposite direction up to
the end stroke.
