Does increasing the incoming air pressure solve the issue?

How to check this:

1. Open the multi-purpose compartment.
2. Remove the cooling liquid tank.
3. Use the compressed air regulator (marked orange) to increase the incoming air pressure depending on the discs you use:
   • For cobalt-chrome discs: 8 bar (120 psi)
   • For other materials: 7 bar (100 psi)
4. Load and unload the heaviest disc that you use.

The location of the compressed air regulator (depends on the series)

Was the disc diameter too large?

How to check this:

1. Open the multi-purpose compartment.
2. Open the working chamber door.
3. Check whether at least one of the following applies:
   • The gripper didn’t properly grab the disc.
   • The disc collided with the opening between the compartment and the working chamber.
   • The disc diameter is too large.  Technical data

Did the stud type track roller move against the recess of the cam disc?

How to check this:

1. Open the multi-purpose compartment.
2. Locate the cam disc including the stud type track roller on the upper left side. See the figure below.
3. Use your finger to feel if there is a small gap (0.3 – 0.5 mm) between the stud type track roller and the recess of the cam disc.
• If there is no gap, the stud type track roller hit the cam disc.

The orange arrow points to the position of the gap
