1) Remove the bent tube assembly from the helmet,
per this chapter.

of the adjustment nipple.
Remove the bent tube and the bent tube adapter.
Before you reinstall the bent tube, connect the
low pressure hose to the regulator and pressurize
it again. Push in on the regulator cover 1/4 inch.
The regulator should just begin to free flow if it is
properly adjusted.

turn the adjustment nipple IN 1/16 of a turn. Only
small adjustments are needed to tune the regulator.
Reconnect the low pressure hose, pressurize it and
test again.
6) If you are unable to obtain a proper adjustment
with the regulator following this procedure, you will
need to disassemble the regulator to check the condi-
tion of the lever.

the bent tube adapter and o-ring. Tighten the adapter
to 30 inch pounds.

this chapter.

cover was pushed in, turn the adjustment nipple OUT
1/16 of a turn. Only small adjustments are needed to
tune the regulator. Reconnect the low pressure hose,
pressurize it and test again.
