3. Go to PARAMETERS page of CRT and ensure PRE-CHARGE DELAY is set to 200. If not, do so at this time.

4. Execute a tool change. A banging noise will be heard as the tool release piston contacts the drawbar.

5. Turn the air pressure regulator ½ turn in. Execute a tool change and listen for the noise described previously. If it is

heard, repeat this step until no noise is heard. There should be no noise with or without a tool in the spindle.

CAUTION!

Only increase the pressure to the point where tool changes become obviously quiet. Any further pressure

increases are not beneficial. Excessive pressure to the pre-charge system will cause damage to the tool changer and

tooling in the machine.
