How To Attach A New Hose
- Loosen the locking ring and remove the knob from the handpiece. Remove the old hose simply by cutting it off close to the knob.
- With a small punch, push the hose / brass fitting back into the knob body. Remove the cut off hose piece. Feed the new air hose through the hole in the knob (Fig. 1).
- Insert the brass fitting into the end of the hose making sure it is fully seated. Moistening the fitting first may help it slip into the hose easier.
- Then apply a small amount of moisture (you can even use “skin oil” from your nose or forehead) around the outside end of the hose next to the brass fitting and pull the hose back (Fig. 2) into the knob until you see the tip of the brass fitting protrude through the side of the knob.
- This must be an air tight fit, so you will have to pull somewhat hard (a few pounds, at least).
