Legend First Stage Service Manual

INTRODUCTION

This manual provides factory prescribed procedures for the

correct service and repair of the Aqua Lung Legend rst-stage

regulator. 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 authorized training through an Aqua

Lung Service & Repair Seminar. If you do not completely

understand all of the procedures outlined in this manual,

contact Aqua Lung to speak directly with a Technical Advisor

before proceeding any further.

WARNINGS, CAUTIONS, & NOTES

Pay special attention to information provided in warnings,

cautions, and notes that are accompanied by one of these

symbols:

WARNINGS indicate a procedure or situation

that may result in serious injury or death if

instructions are not followed correctly.

CAUTIONS indicate any situation or tech-

nique that will result in potential damage to

the product, or render the product unsafe if

instructions are not followed correctly.

NOTES are used to emphasize important points,

tips, and reminders.

SCHEDULED SERVICE

If the regulator is subjected to less than 50 dives per year, it is

permissible to overhaul it every other year with an inspection

procedure being performed on the “off” years. For example:

Year #1: Inspection; Year #2: Overhaul; Year #3: Inspection

Year #4: Overhaul, and so on.

Both Inspections and Overhauls need to be documented in

the Annual Service & Inspection Record in the back of the

Owner’s Manual to keep the Limited Lifetime Warranty in ef-

fect.

If a regulator is subjected to more than 50 dives per year, it

should receive the complete overhaul.

An Ofcial Inspection consists of:

1. A pressurized immersion test of the entire unit to check

for air leakage.

2. Checking for stable intermediate pressure that is within

the acceptable range.

3. Checking for opening effort that is within the acceptable

range.

4. Checking for smooth operation of the control knob and

venturi switch.

5. A visual inspection of the lter for debris or discoloration.

6. A visual inspection of the exhaust valve to see that it

is in good shape and that it’s resting against a clean

surface.

7. A visual inspection of the mouthpiece looking for tears

or holes.

8. Pulling back hose protectors and checking that the

hoses are secure in the hose crimps.

If a regulator fails item #1,2,3 or 4 the entire regulator should

be overhauled. If a regulator fails 4,5,6 or 7 it will be up to

the technician’s discretion whether or not a full overhaul is

required.

GENERAL GUIDELINES

1. In order to correctly perform the procedures outlined in

this manual, it is important to follow each step exactly

in the order given. Read over the entire manual to

become familiar with all procedures before attempting to

disassemble the rst-stage, and to learn which specialty

tools and replacement parts will be required. Keep the

manual open beside you for reference while performing

each procedure. Do not rely on memory.

2. All service and repair should be carried out in a work

area specically set up and equipped for the task.

Adequate lighting, cleanliness, and easy access to all

required tools are essential for an efcient repair facility.

3. The regulator body will need to be secured in a vise

when removing certain threaded parts, including the

inlet tting (30) and spring retainer (31). NEVER SE-

CURE THE REGULATOR BODY DIRECTLY IN A VISE.

Instead, install a vise mounting tool (PN 100395) into

the high pressure port, then secure the vise mounting

tool in the vise. If you do not have a vise mounting tool,

use an EXPIRED CO

cartridge attached to a high pres-

sure adapter (³₈" female to ⁷₁₆" male). Never screw a

directly into a low pressure port in case the neck of

the CO

cartridge breaks off, leaving the threads stuck

in the regulator.

3. As the regulator is disassembled, reusable components

should be segregated and not allowed to intermix with

nonreusable parts or parts from other units. Delicate

parts, including inlet ttings and crowns which contain

critical sealing surfaces, must be protected and isolated

from other parts to prevent damage during the cleaning

procedure.

4. Use only genuine Aqua Lung parts provided in the Leg-

end rst-stage overhaul parts kit (PN 900014). DO NOT

attempt to substitute an Aqua Lung part with another

manufacturer’s, regardless of any similarity in shape or

size.
