• Keep the gantry on the right edge of the CMC.

• Point the replacement head so that the foot block faces toward the CMC and the wheels are close to the bottom of the gantry.

• Line up the wheels on the head to the center channels of the gantry arm and ease the head onto the gantry.

• Roll the head up the gantry until it lines up to the head grabber arm on the right side of the gantry.

NOTE: If you are installing the head and having difficulty getting the head wheels onto the gantry, see “Head Wheel Adjustment” further below.

• Holding the head in position so that the head lines up neatly to the head grabber arm, replace the two 5/32” screws, making sure they go into the head grabber arm and into the head and tighten firmly.

• Connect the air to the head by twisting the two air fittings together, matching colors.

• Connect the head power plug (square connection) to the head grabber arm.

• Reinstall the gantry hood, replacing the screws removed earlier.

• Lift the head up so that the foot block does not strike the side of the board and move the gantry to the left. Turn on the air.

• You have installed the head.

IMPORTANT: PROCEED TO HEAD WHEEL ADJUSTMENT INSTRUCTIONS.

WARNING: To avoid damage to the head, do not loosen the head wheel screws without first aligning the head to the middle of the board.

• Go to the cut preview screen.

• Manually move the head and the gantry to the middle of the board, and click the power button and align the head in this position.

• Locate the head wheel adjustment Allen screws on the left side of the head under the blade depth adjustment plate.

• They are next to the head wheels and are marked with red dots. Do not touch the Allen screws on the wheels themselves.

• Loosen each head wheel adjustment Allen screw only until the wheels are loose; about two full turns.

• The wheels are spring-loaded and will pop into place.

NOTE: If having difficulty getting the head wheels onto the gantry during head installation, loosen the head wheel adjustment screws, roll the head onto the gantry, then continue with the following instructions.

• Grasp the head with both hands and gently rock it back and forth to ensure that the wheels are lined up to the gantry grooves.

• Holding the head up so that it is level with the board, retighten the head wheel adjustment Allen screws consecutively; tighten the top screw half a turn, then the bottom screw half a turn, back to the top and continue until they are both tight.

• Check each of the head wheels to make sure there is no movement.

• There are the two visible wheels on the left side of the head under the blade depth adjustment plate, and two wheels on the backside of the gantry, which can be felt by hand.

• They should sit firmly into the gantry groove and be difficult to turn.

• If not, repeat these steps of loosening the wheels, gently rocking the head back and forth, then retightening the wheels.

• The head wheels have now been adjusted.

• Click on the reset motors button, click OK on the reset motors screen if it displays.

• Return the head to the home position.

• Reinstall the blade cartridge if necessary.
