Note: Lubricating the O-rings before placing them on the nozzles is important to ensure

Install new O-rings as shown below:
While holding the O-ring on the Exchange
Tool with your thumb, pull the entire O-
ring changer downward, away from the
nozzle.
The O-ring is now removed from the

Place a new, greased O-ring on the shaft
of the O-Ring Exchange Tool. Make sure
the O-ring is well below the pin.

Tool as deep as possible into the nozzle
hole:
Use your thumb and forefinger to push
the O-ring up the shaft onto the nozzle.
Continue pushing until the O-ring is
seated in the nozzle groove.
