GENERAL CONVENTIONS

Unless otherwise instructed, the following terminology and tech-

niques are assumed:

When instructed to remove, unscrew, or loosen a threaded

part, turn the part counterclockwise.

When instructed to install, screw in, or tighten a threaded

part, turn the part clockwise.

When instructed to remove an o-ring, use the pinch method

(see figure) if possible, or use a brass or plastic o-ring

removal tool. Avoid using hardened steel picks, as they may

damage the o-ring sealing surface. All o-rings that are re-

moved are discarded and replaced with brand new o-rings.

Pinch Method

Press upwards on sides

of o-ring to create a

protrusion. Grab o-ring

or insert o-ring tool at

protrusion.

The following acronyms are used throughout the manual:

MP is Medium Pressure; HP is High Pressure; LP is Low

Pressure.

Numbers in parentheses reference the key numbers on the

exploded parts schematics. For example, in the statement,

"...remove the o-ring (3) from the piston (4)...", the number 3

is the key number to the piston o-ring.

DISASSEMBLY PROCEDURES

NOTE:

Before performing any disassembly, refer to the

exploded parts drawing, which references all mandatory

replacement parts. These parts should be replaced with

new, and must not be reused under any circumstances

- regardless of the age of the regulator or how much use it

has received since it was last serviced.

CAUTION:

Use only a plastic or brass o-ring

removal tool (p/n 944022) when removing o-rings

to prevent damage to the sealing surface. Even

a small scratch across an o-ring sealing surface

could result in leakage. Once an o-ring sealing

surface has been damaged, the part must be

replaced with new. DO NOT use a dental pick, or

any other steel instrument.

Pull back the hose protector to expose wrench flats. Using a

⁹₁₆" wrench, unscrew the hose from the first stage.

Using a 4mm Allen wrench, unscrew the HP (20) and MP

(10) port plugs. Remove the o-rings (9,21) from the port

plugs.

Remove yoke screw (22) and dust cap (19). Thread a first

stage vise mounting tool into the HP port.

Secure mounting tool in a vise. Using a large crescent

wrench, remove the inlet fitting (17) and the yoke (18).

Remove the yoke washer (13).
