ULTRAFLEX
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
3.11 and in the bleeding procedure of ULTRAFLEX cylinders. 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.
DANGER
Use only compatible hydraulic oils, indicated in the paragraph "technical features" and "filling and purging".
Do not use brake oils or automatic transmission fluid (ATF) in any case.
CAUTION
If the self-locking nuts are disassembled, they must be replaced. (Contact our assistance service, see
page 6).

5.2 Steering wheel disassembly

To remove the steering wheel from the pump shaft, use a suitable extractor.
WARNING
Do not use a hammer or other tools that could seriously damage the pump.
