5 MAINTENANCE
5.1 Ordinary maintenance
WARNING
Poor installation and maintenance may result in loss of steering and cause property damage and/or perso-
nal injury. Maintenance requirements change according to climate, frequency and the use. Inspections are
necessary at least every year and must be carried out by specialized marine mechanics. Check the cylinder
fittings and the seals and the helm gaskets to prevent leaks. Replace them if necessary.
To keep a suitable oil level in the tank, fill and bleed the system as described in this manual in paragraph
3.7.
Check the hose and the entire system wear, the nut and bolt tightening every six months and make sure that
they are not damaged.
Clean the system using water and non-abrasive soap.
WARNING
Use only compatible hydraulic oils, indicated in the paragraph "technical features" and "filling and bleeding".
Do not use brake oils or automatic transmission fluid (ATF) in any case.
5.2 Troubleshooting
WARNING
Whenever the following checks need the removal and/or disassembly of the steering system components,
such work must be carried by specialized staff. ULTRAFLEX offers general information only and is not
responsible for any consequences resulting from incorrect disassembly.
PROBLEM
During the filling, the
steering system becomes
completely jammed.
The system is very difficult
to fill.
Air keeps bubbling at the
top of the steering system
tank even after filling the
system completely.
The steering system is stiff
and hard to turn, even
when the boat is not
moving.
