continue turning until the tab and notch align. (See Figure 10)

petroleum jelly. (See Figure 11)

will ensure that the pressure cylinder seal is seated properly. Take care not to roll the o-ring seal out of
the groove as you reinsert the pressure cylinder. Realign the tab on the tank with the notch on the
pressure cylinder and make sure the flange on the pressure cylinder is flush with the flange on the tank.
