ADVANCED SL3 INLINE 
REGULATOR MAINTENANCE
This pro
cedure is only required if  you are fixing 
a supercharging SL3 inline regulator (common 
symptoms of  supercharging are a very high velocity
first shot and/or large variances in shot to shot 
consistency). 
Place 
a 3/32” hex key through the adjuster top 
section 
(SEE FIGURE 18A), then insert a 1/8” hex 
key into the bottom of  the adjuster screw and
 carefully 
turn it counter-clockwise until the two parts begin to 
unscrew freely 
(SEE FIGURE 18B). With your fingers 
fully unscrew the two parts taking care not to lose any 
of  the internal components 
(SEE FIGURE 18C). 
Inside t
he adjuster screw 
C
 you will find a regulator 
seal 
A
, purge poppet and spring 
B
 (together these 
two form the purge poppet assembly
) (SEE FIGURE 
18D)
. Inspe
ct and clean the regulator seal, turning it 
over if  one side appears excessively worn or damaged 
or replace if  necessary. Inspect and clean the purge 
poppet or replace if  
necessary.

Place th
e purge poppet and attached spring in the 
central hole in the regulator seal, then insert these 
parts into the adjuster screw 
(SEE FIGURE 18E). 
Wit
h the regulator seal, purge poppet and spring 
installed back into the adjuster screw, replace the 
adjuster top sectio
n (SEE FIGURE 168F). Screw 
the two parts tightly together using 1/8” and 3/32” 
hex keys
 (SEE FIGURE 18B). Refer to the ‘The SL3 
Inlin
e Regulator’ section on page 57 to re-assemble 
the SL3 inline regulator.

If the Purge Poppet Assembly is removed for maintenance ensure 
that is it re-installed correctly, failure to do so may seriously damage 
the Etek4 solenoid valve.
