BALANCED PISTON FIRST STAGE REGULATOR
 

TUNING AND ADJUSTMENT

4. 

To replace a spring isolator (17), remove the End-cap (22) and End-cap ring (22)
by inserting one LP tightening bar into one of LP port in the end cap and one HP
tightening bar into one of the HP ports in the body (13).

NOTE

Make  certain  the  Tightening  Bars  are  firmly  seated  into  both  plugs  (23)  &  (10)  before
attempting to rotate the end cap (22) in a counterclockwise direction.

5. 

Remove piston being careful not damaged the knife edge or stem. Then remove
HP spring (18) from main body.

6. 

Remove  the  yoke  knob  (1)  and  then  remove  the  retainer  ring  (4).  The  filter
assembly can then be removed using a 3/8” Allen key. Also remove the HP seat
assembly, this should fall out into hand.

7. 

Replace spring isolators as required to adjust the intermediate pressure. Apply a
light film of lubricant (see section 1.1) to both sides of the spring. Before installing
the HP spring.

8. 

Install  a  genuine  Tusa  piston
installation  bullet  into  the  HP  piston
stem. 

Refer to Figure 6-a. 

Carefully

lower  the  HP  piston  (bullet  first)  into
the  main  body  until  the  bullet  and
stem have passed through the piston
stem  o-ring  (12).  Turn  over  to  allow
the  installation  bullet  to  fall  out  in
your hand.

CAUTION

Failure to use this bullet may result in cutting the piston stem o-ring (12) or damaging the
sealing (knife) edge if the piston stem during installation.

9.

Reinstall  the  HP  seat  and  filter  assemblies,  snap  retainer  ring  into  groove  and
replace yoke knob. Refer to section 6.1 for proper torque specifications.

NOTE

Use care and caution to avoid damage to the surface of the body (13). DO NOT over-
tighten the vise onto the soft brass of the first stage.
