Removing the Air Clamp

Info
When an Air Clamp blows/leaks on the CMC 5000, 8000 and 8500, it needs to be replaced.

Determine which Clamp has blown.
- If necessary, run a large mat without the Blade in the Blade Cartridge (Blade Cartridge must still be inserted in Head) and listen for air escaping.
Turn off the air supply.
Move the Gantry to the right until it moves no further. Determine which Clamp is leaking.
Remove the appropriate Clamp mounting screws with an Allen wrench.

Loosen the 7/64” Allen Screw holding the Air Clamp, and gently lift the Vertical/Horizontal Clamp to view the small air hose fitting.
Lift fitting from its groove and disconnect it by unscrewing the two halves.
- Note that the CMC 5000 air fitting is straight, and the CMC 8000/8500 has an elbow fitting.
- On later machines, simply pull the two hoses apart.

Lay the Vertical/Horizontal Clamp upside down to look at its construction.
Loosen the two Allen screws at each end of the rubber tube until you can pull the Air Clamp out.
