4 Servicing & Maintenance
The unit comes with a 12 month warranty covering all parts,
including valves. It is essential that it is returned to our
factory or to the dealer from which it was purchased for
repairs to be carried out otherwise the warranty is
invalidated. There is, however, one important exception to
this rule:
4.1 Valves/Tubes
The most likely cause of a problem is a faulty valve.
Before sending a unit back to us, please contact us
and we will advise whether it’s a simple valve fault and
if so we may elect to send a spare. However it is
always best to return it to your dealer or to us as re-
alignment will ensure optimum results.
