STEP 1:

Insert a blunt tipped needle into the space between the airway and the outer wall of the cartridge. 
With the cartridge held upright fill the reservoir with precise fill volume of oil. DO NOT OVERFILL OR ALLOW OIL TO ENTER CENTER AIRWAY.

STEP 2:

Within One (1) minute after filling, insert and press fit
the mouthpiece until it is fully seated.  Mechanical assistance, such as an arbor press, or channel lock pliers are required to fully seat the mouthpiece. 
If using pliers with cushion jaws, please use cloth or tape to prevent damage.  Failure to insert the mouthpiece immediately may cause leakage.
