it again. Push in on the regulator cover 1/4 inch.
The regulator should just begin to free flow if it is
properly adjusted.

small adjustments are needed to tune the regulator.
Reconnect the low pressure hose, pressurize it and
test again.

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.
