Installation and Maintenance Manual

5.2 Troubleshooting

Whenever  the following  checks need  the removal  and/or disassembly  of  the  steering system  components,

such work must be carried by specialized staff. 

UFLEX 

offers general information only and is not responsible

for  any  consequences  resulting  from incorrect  disassembly.

    PROBLEM

                CAUSE

                         SOLUTION

Blockage in the hoses between

steering  system and  cylinder.

Air in  the system.

Leaks  from the  cylinder

bleeder.

Coiled  hose.

Helm has been mounted upside

down.

Restrictions in hoses or  fittings.

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.

Replace  hoses.

Repeat the   filling  and the  bleeding

procedure  of  the  system.

Install  horizontally the  hoses and  in

any case with a  maximum inclination

of 3cm  each  meter.

Tighten the  bleeder on  the

cylinder.

Uncoil and  straighten  the  hose.

Mount the helm with the filling hole in

up position.

Look  for and  remove the  restriction.

WARNING

WARNING

5.1 Ordinary maintenance

5 MAINTENANCE

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

3.5.

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.

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.

WARNING

WARNING

The  damaged  hose  must  be  replaced,

otherwise it  may  cause  loss  of  steering

and  severe  personal  injury  or  property

damage.

The steering system is stiff

and  hard  to  turn,  even

when  the  boat  is  not

moving.

Air in  oil

Repeat the   filling  and the  bleeding

procedure  of  the  system.
