XL4 Second Stage Maintenance Manual
(AP5840 Issue 1 )
INTRODUCTION
This manual provides factory prescribed procedures for
the correct maintenance and repair of the Apeks XL4
second stage regulators. It is not intended to be used
as an instructional manual for untrained personnel. The
procedures outlined within this manual are to be performed
only by personnel who have received factory authorised
training through an Apeks Service & Repair Seminar. If
you do not completely understand all of the procedures
outlined in this manual, contact Apeks to speak directly with
a Technical Advisor before proceeding any further.
It is recommended that the Apeks XL4 2nd Stage regulator
should be examined annually regardless of usage.
A full service should be performed every two years.
However, If you are at all unsure about the correct
functioning of the Apeks XL4 2nd Stage then it must be
ofcially inspected immediately.
All service and inspection details need to be documented to
keep the Limited Lifetime Warranty in effect.
A Second Stage Ofcial Inspection
consists of:
1. Checking the lever height with setting tool.
2. Checking for opening effort that is within the
acceptable range.
3. A pressurised immersion test of the entire unit to check
for air leakage.
4. A visual inspection of the exhaust valve(s) to see that
they are in good condition and that it is seating against
a clean and undamaged surface.
5. Pulling back hose protectors and checking that the
hoses are secure in the hose crimps.
6. A visual inspection of the mouthpiece looking for tears
or holes and checking the general condition.
If a regulator fails steps 1,2 or 3 the entire regulator should
be serviced. If a regulator fails step 4 it will be up to the
technician’s discretion whether or not a full service is
required. Failure of step 5 or 6 requires replacement of the
part.
