3. Thread the end cap (9) onto the dry chamber until

handtight. Using an in/lbs torque wrench and an 8mm hex

key adapter, tighten the end cap to 35 in/lbs. Recheck the

MP to make sure it is still at 137 psi (standard) or 13 psi

(supreme).

4. Close the cylinder valve and depressurize the regulator.

Remove the test gauge and reinstall the port plug(s).

This Ends Reassembly

FINAL TESTING

1. With the port plugs and at least one properly adjusted

second stage installed, slowly open the cylinder valve and

pressurize the first stage. Completely submerge the first

stage in fresh water and check for leaks.

NOTE:

Do not confuse bubbles from trapped air

with a true leak. If there is an air leak, bubbles will

come out in a constant sream.

If a leak is detected, note the source of the leak and refer to

Table 1:Troubleshooting Guide, p.11 for possible causes

and corrective actions.

NOTE:

Extremely small leaks may be better

detected by applying a soap solution or Snoop

to the leak area. Bubble streams will indicate the

source of the leak. Before disassembling to

correct any leaks, rinse the entire regulator

thoroughly with fresh water and blow out all

residual moisture with filtered, LP (30 psi) air.

Disassemble and remedy the problem by

referring to Table 1: Troubleshooting Guide, p. 11.

1. Depress the second stage purge to ensure that the

volume of airflow is adequate to clear the second stage.

. Breathe deeply from the mouthpiece. A properly serviced

and adjusted regulator should deliver a smooth, uninterrupted

airflow upon deep inhalation; without excessive effort,

hesitation, or freeflow. If any abnormalities or problems occur,

refer to Table 1: Troubleshooting Guide, p. 11.

When completed, close the cylinder valve and depressur-

ize the regulator. Remove the first stage from the valve and

secure the dust cap in place.

This concludes the service

procedures for the Legend First Stage
