The bottom wheels are spring-loaded, the top wheels are on a center-pivot.

Move the top set of wheels as needed for ease of installation (picture shows gantry Gantry being put on rail from back).

Before installation, look at the top set of gantry Gantry wheels.

Both sets of wheels are spring-loaded.

Wheels may need to be eased over the rails (picture shows gantry Gantry being put on rail from back).

Hold the gantry Gantry near the left side of the CMC and line up the upper then lower wheels of the gantry Gantry to the center channel of the rails.

Carefully ease the Gantry onto the left side of the Rails, taking care that all the wheels line up.

Lightly pull the coiled drive belt Drive Belt toward the right to take up the slack and pull the belt anchor into place flush with the end of the CMC.

Remove the rubber-band rubberband from the drive belt Drive Belt and pull the loose belt end to the right, making sure that the drive belt Drive Belt is not twisted and that the teeth are facing down toward the board Board into the rail channel.

If necessary, rotate the alignment pulley so that the red mark is on the top.

Line up the red mark of the drive belt Drive Belt to the red mark of the alignment pulley; this may require moving the gantry Gantry a bit in either direction.

Pull drive belt Drive Belt to the right to take up slack.

Do not move the gantry Gantry after red marks line up.

Slide the screw of the belt end into the belt tensioner slot.

Go back and make sure red lines are still lined up.

The screw of the belt end snaps into the belt tensioner slot.

Remove the 5/32” Allen screws and washers from the belt tensioner.

Leave the gantry Gantry where it is.

Loosen one full turn only the 3/16” Allen belt tensioner screw from the right bottom side of the lower rail marked with a red dot.

The belt tensioner should spring fully into place.

Repeat steps 1 through 10 with the upper rail.

Place the two Allen screw and washer into the holes provided on the lower gantry Gantry plate.

Place them so that the screw protrudes only slightly from the back of the plate.

Go back and snugly tighten the 3/16” Allen belt tensioner screw from the right bottom side of the lower rail and the right bottom side of the upper rail marked with a red dot.

The board Board cable connects the gantry Gantry on the CMC to the Driver Pack, which is a shoebox-sized peripheral.

Connect the male end of the board Board cable to the back of the Driver Pack by aligning the pins and turning the locking ring until it seats itself and locks into place.

Connect the female end of the board Board cable to the back of the gantry Gantry in the same manner.

Move the gantry Gantry to the far right of the CMC and back to the left to make sure the board Board cable does not get caught on anything.

If the board Board cable is obstructed, this will affect the cuts.

Follow the airline with the red connector from the top of the gantry Gantry and connect it to the right side of the air regulator by inserting the red connector on the end and twisting it into place.

Follow the airline with the blue connector from the top of the gantry Gantry and connect it to the matching blue airline on the back of the boardBoard.

Make sure that none of the airlines are crimped.

Turn on the air.

Move the gantry Gantry to the right edge of the CMC.

Point the head Head so that the Footblock faces toward the CMC and the wheels are close to the bottom of the gantryGantry.

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

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

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

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

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

Lift the head Head up so that the Footblock does not strike the side of the board Board and move the gantry Gantry to the left.

Turn on the air.

The head Head is installed.

Go to the cut preview screen.

Manually move the head Head and the gantry Gantry to the middle of the boardBoard, and click the power button.

The head Head will align to this position.

Locate the Head Wheel Adjustment Allen Screws by looking at the left side of the Head just under the Blade Depth Adjustment Plate.

They are located next to the Head Wheels and are marked with red dots.

Do not touch the Allen Screws attached to the Wheels themselves.

Loosen each Head Wheel Adjustment Allen Screw until the Wheels are loose; about two full turns.

The Wheels are spring-loaded and will pop into place.

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

Retighten the head 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 Head wheels to make sure there is no movement.

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

They should sit firmly into the gantry Gantry groove and be difficult to turn. If not, repeat these steps of loosening the wheels, gently rocking the head Head back and forth, then retightening the wheels.

Reinstall the hoods onto the Gantry, replacing the screws you removed earlier.

Look at the backside of the Trimmer and locate the T-Nut on the glides.

Make sure that the T-Nut lines up with the glide on both the upper and lower sections of the Trimmer.

Holding the Straight Line Trimmer steady (a second person helps here), carefully slide the Trimmer onto the channels on the right side of the Board, making sure that the T-Nuts slide into the channel of both the upper and lower rails.

Make sure all of the wheels make contact with the top rail, and that they don’t spin freely.

Make sure they are making contact with the top rail.

If any of the wheels are not making contact, contact customer support.
