es in order to vent the coupling and minimize the risk of sudden
component separation, which has the potential to cause opera-
tor injury.
Never open a quick coupling with a screwdriver in order to
ventilate the air.

Follow this order when working with claw couplings.

How to open a claw coupling: How to close a claw coupling:
Close the ball valve. Make sure that the two claw
couplings are mounted together.
Use claw couplings with lock nut
(LNH) or use a lock spring for
safer locking.
Run the tool so the air ventilates out.

Release the claw coupling. Open the ball valve gently.
