Head Replacement: CMC 5000

Shut down the computer. Remove the plastic HEAD HOOD (small Phillips screws with star washers).

Unplug the HEAD POWER PLUG by gripping the white plug housing firmly (not the flexible cable), and gently rock it back and forth while pulling up at the same time.

Disconnect the air supply. Disconnect the AIR LINE by unscrewing the airline connector.

Open the HEAD as if you were changing the BLADE. Remove the small Allen screw to the right of the right-hand HINGE, if one is present. Remove the HORIZONTAL BOLT from the right HINGE on the TROLLEY PLATE using the 9/64 Allen Wrench.

The TROLLEY PLATE is the flat plate located between the GANTRY arms.

Gently slide the HEAD to the right (rocking up and down may help). The HEAD should now slide off the HINGE pins. Place it in a safe position where it won’t be damaged.

Gently insert the HEAD onto the bolt located on the left HINGE.

Warning: Take care when handling the HEAD, as the BLADE is sharp. Note the position of the BLADE for future reference.

Holding the HEAD carefully in place, align the hole on the right side of the HEAD to the hole located on the right HINGE.

Tighten the HORIZONTAL BOLT into place using the 9/64 Allen Wrench. The connection will be tight, so take care not to strip the screw. After you have tightened the screw, back it off 1/8th of a turn.

Warning: Do not overtighten the HORIZONTAL BOLT, or the HEAD will not rotate into the closed position.

Connect the HEAD POWER PLUG in the same manner as you disconnected it.

Connect the AIR LINE in the same manner as you disconnected it. Reattach the plastic HEAD HOOD.

You are finished!
