NEVER SKIP AHEAD ON ANY STEP! Your Head may vary from model shown, but the connections are the same.

• Never pull/push on the Drive Shaft to move the Gantry.

• Use the Gantry Arm to move/pick up the Gantry.

• Do not pick up the Head using only the Blade Depth Knob or the Head Cover.

• Pick up the Head by holding the “D-Shaped” Upper and Lower Head Faceplates.

• Turn the shut off valve on the Blue Air Line, and unplug the Blue Air Line by untwisting the Blue Air Fittings.

• Turn the bottom locking knob Clockwise to loosen.

• Turn the top locking knob Counter-Clockwise to loosen.

• Slide the Straight Line Trimmer off of the Board and set aside in a safe place.

• Click the Reset Motors button to turn off power to the motors.

• Remove the Blade Cartridge from the Head.

• Turn off the Air.

• Remove the Gantry Cover from the lower part of the Gantry by unscrewing the screw that holds it in place and set aside.

• Move the Gantry to the right side of the Board until the Footblock is off the Board.

• Look at the right side of the Head and locate the Head Grabber Arm (on the right side of Gantry just above the Head).

• Unconnect the Head Power Plug (square connection) from the Head Grabber Arm.

• Disconnect the Air from the Head Grabber Arm by untwisting the two Air Fittings.

• Remove the two 5/32” screws from the Head Grabber Arm and set aside, taking care to support the Head so that it doesn’t roll/fall off the Gantry.

• Pull the Head slowly to the bottom of the Gantry until it comes away from the Gantry and carefully set aside.

• Remove the 3/16” Stop Screw from the left bottom Board Rail (located on the top of the Bottom Board Rail) and set aside.

• Remove the 5/32” Allen Screws and washers from the lower Gantry Plate.

  • These were placed here to assist in removing the Gantry.

• You will have one of two models of the Gantry.

• You will either have two Air Lines, or one Air Line and a Clamp Valve; both models have the same Board Cable connection.

Look for Red Dots (only these screws are to be adjusted).

• Disconnect the Air Lines to the Gantry by untwisting the air fittings.

• Disconnect the Board Cable by turning the Black Locking Ring until it comes away from the Gantry.

• Disconnect the Clamp Valve Plug (if applicable) from the top of the Gantry by grasping it and gently pulling/separating it from the matching Clamp Valve Plug on the Gantry.

• The Clamp Valve Plug is unplugged.

• Loosen one full turn only the 3/16” Allen Belt Tensioner Screw from the right bottom side of the lower Board Rail marked with a red dot.

• Only loosen the Belt Tensioner Screw enough so that there is some movement in the Belt Tensioner; about one full turn.

• The Belt Tensioner springs should be visible.

WARNING: Make sure you do not over loosen this screw. One full turn is usually sufficient.

• Locate the Hole on the end of the Belt Tensioner for the 5/32” Allen Screw.

• Place the 5/32” Allen Screw and washer into the Belt Tensioner Hole.

• Tighten it until Belt Tensioner is flush with the Board Rail and the springs are not visible.

• Go back and tighten the 3/16” Allen Belt Tensioner Screw from the right bottom side of the lower Board Rail marked with a red dot.

• Lift the Drive Belt End out of the slot/recess of the Belt Tensioner Slot.

• You may need to push the Drive Belt End a bit to the right in order to get a hold of it.

• Wind up the Drive Belt and rubber band it together.

• Repeat these steps with the upper Board Rail.

• Move the Gantry slightly to the left to dislodge the Belt Anchors that are sunk into the left ends of the top and bottom Board Rails, to which the Drive Belts are attached.

• If they are in your way, lay the Belt Anchors over the Drive Belt and rubber-band them together.

• The Belt Anchors will be dislodged.

• Grasp the Gantry on the bottom and along the Gantry Arm and gently roll the Gantry off the Board Rails on the left side of the Board and set aside.

• A second person can stand in front of the Board, grasping the Gantry at the bottom and along the Gantry Arm, if you need two people.

• The Gantry only weighs about 30lbs, but it is large and awkward.

NEVER SKIP AHEAD ON ANY STEP!

• Before installation, look at the bottom set of Gantry Wheels.

• The bottom Gantry 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 being put on Board Rail from the back).

• Before installation, look at the top set of Gantry Wheels. Both sets of wheels are spring-loaded.

• Wheels may need to be eased over the Board Rails (picture shows the Gantry being put on the Board Rails from the back).

• Hold the Gantry near the left side of the Board and line up the upper then lower Gantry Wheels to the center channel of the Board Rails.

• NOTE: Installation is easier if you line up the upper Gantry Wheels first, then slide the lower Gantry Wheels onto the Board Rail. Sometimes having a second person for this step helps a lot.

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

• Make sure that the Drive Belt lies within the Board Rail channel on either side and is not pinched between the Gantry and the Board Rail.

• Roll the Gantry past where the Stop Screw was removed.

• Replace the 3/16” Stop Screw into the left bottom Board Rail. Roll the Gantry to the far right of the Board and back to the left to make sure it moves smoothly.

• Slide the Belt Anchor into place on the left side of the Board.

• Lightly pull on the coiled Drive Belt to the right to take up the slack which moves the Belt Anchor flush with the end of the Board Rail.

• Loosely lay the rolled up Drive Belt along the Board Rail channel.

• If necessary, rotate the Toothed Pulley so that the red mark is on the top.

• Line up the red mark of the Drive Belt to the red mark of the Toothed Pulley; this may require moving the Gantry a bit in either direction.

• Pull the Drive Belt to the right to take up slack.

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

• Remove the rubber band from the Drive Belt and pull the loose Drive Belt to the right, making sure that the Drive Belt is not twisted and that the teeth are facing down toward the Board into the Board Rail channel.

• Slide the screw of the Drive Belt End into the Belt Tensioner Slot.

• Click the screw of the Drive Belt End into the Belt Tensioner Slot into the slot/recess on the end.

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

• Locate 5/32” Allen Screw on the Belt Tensioner.

• Remove the 5/32” Allen Screw and washer from the Belt Tensioner and set aside.

• Leave the Gantry where it is.

• Loosen one full turn only the 3/16” Allen Belt Tensioner Screw from the right bottom side of the lower Board Rail marked with a red dot.

• The Belt Tensioner should spring fully into place.

WARNING: Make sure you do not over loosen this screw. One full turn is usually sufficient.

• The Belt Tensioner should spring fully into place.

• Repeat these steps with the upper Board Rail.

• Place the Allen Screws and washers removed from the Belt Tensioner into the lower Gantry Plate in the holes provided.

  • These multi-purpose Allen Screws will be used during the lifetime of your Wizard, so it is important to place them here.

  • Only screw them in enough until the screw slightly protrudes from bottom of plate.

• Go back and snugly tighten the 3/16” Allen Belt Tensioner Screw from the right bottom side of the lower Board Rail and the right bottom side of the upper Board Rail marked with a red dot.

• Keep the Gantry on the right edge of the Board.

• Point the Head so that the Footblock faces toward the Board and the Head Wheels are close to the bottom of the Gantry.

• Line up the Head Wheels to the center channels of the Gantry Arm.

• Ease the Head onto the Gantry.

• Roll the Head up on the Gantry until it lines up to the Head Grabber Arm (attached to 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.

• Make sure that the Head and the Head Grabber Arm line up together neatly to ensure correct fitting.

• Replace the two 5/32” Screws by making sure they go into both the Head and into the Head Grabber Arm then 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.

• Lift the Head up carefully from the Board as you roll the Gantry to the left so that the Footblock does not strike the side of the Board.

• Reinstall the bottom Gantry Cover onto the lower part of the Gantry, replacing the screw you removed earlier.

• Turn on the Air.

• You have installed the Head.

IMPORTANT: PROCEED TO HEAD WHEEL ADJUSTMENT INSTRUCTIONS AFTER REINSTALLING THE STRAIGHT LINE TRIMMER, WHICH IS LOCATED FURTHER BELOW.

• NOTE: A Blade is probably still installed, so take care when handling the Straight Line Trimmer.

• 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 Rail, making sure that the T-Nuts slide into the channel of both the upper and lower Board Rails.

• Move the Straight Line Trimmer to the right until it stops.

• Slowly tighten the bottom locking knob COUNTER-CLOCKWISE until it is snug.

• Slowly tighten the top locking knob CLOCKWISE until it is snug.

• Plug in the Blue Connector Air Line from the ST 500 into the Blue shut off valve on the “Y” Connector.

• Turn on the Blue shut off valve on the “Y” connector to turn on the air.

Be VERY CAREFUL when connecting the large Board Cable. Align the four in-line pins carefully before applying pressure to plug them in. If forced in incorrectly, they WILL cause malfunction of the Wizard Mat Cutting system.

• The Board Cable connects the Driver Pack to the Gantry.

• The Driver Pack is the shoebox-sized peripheral with a round plug that the Board Cable plugs into.

• Connect the large Board Cable to back of the Driver Pack by aligning the four in-line pins and turning the locking ring until it “seats itself” and locks into place.

• Connect the other end of the Board Cable to the back of the Gantry in the same manner.

• Move the Gantry to the far right of the Board and back to make sure the Board Cable does NOT get caught on anything.

• If the Board Cable is obstructed, this WILL affect your cuts.

• Look at the Serial Number of your Board, which is located on a label in the lower left corner of the Board.

• If the Serial Number begins with BA-02, go to Attaching Air Lines BA-02-#####.

• Otherwise, follow the directions for Attaching Air Lines BA-03-######.

• Go back and make sure that the Air Lines on the back of the Board are not pinched between the Board and the Stand.

• If you have not already done so, reattach the Air Lines on the inside of the Stand Arms to ensure maximum air flow.

• Connect the Blue Connector from the top of the ST 500 to the Blue Connector/Shut Off Valve of the “Y” Connector.

• Connect Red Connector from the top of the Gantry to the Red Connector of “Y” Connector; only one side will fit.

• NOTE: If you did not install the SL 500, this Red Air Line Connector from the Gantry would plug into the right side of the Air Regulator.

• Plug in the Red Air Line Connector from the bottom of the “Y” into the right side of the Air Regulator.

• Plug the Air Line coming off the left side of the Air Regulator into your main air supply via 1/4” NPT female connector, or the quick disconnect, whichever type you purchased (shown is the black threaded fitting connected to a 1/4” NPT female adaptor).

• Your air compressor should have at least 100 - 120 PSI.

• It is suggested that Teflon tape be used on the threads of the black fitting to reduce possible air leakage.

• Strap the Air Regulator, glass bowl down to the left large wall bracket or left stand side with cable ties provided in your Tool Kit, making sure not to crimp any of the Air Lines.

• Connect Blue Connector from the top of the Gantry to the Blue Connector on the back of the Board.

• Turn on the Air.

• Continue to Calibration and Alignment of the Straight Line Trimmer.

*WARNING: The Air Regulator comes factory-set. Do not make any adjustments to it.

• Locate the Air Valve on the back of the Board on the right side.

• Note the 3 connections from the Air Valve.

• Take the Clamp Valve Plug (Grey cable with the Green Power Plug) and plug it into the Clamp Valve (the matching Green Plug on the top of the Gantry).

• Take the Clear Air Line with the Red Connector from the Air Valve and Plug it into the Air Line with the Red Connector at the top of the Gantry by giving it a 1/4 turn onto the locking connector.

• The top of the Straight Line Trimmer has an Air Line coming out of the back it, which connects to a Blue Connector/Shut Off Valve on a “Y” Connector.

• Take the Black Air Line with the Red Connector from the Air Valve and Plug it into the Red Connector of the “Y” on the Straight Line Trimmer.

• Only one will fit.

• NOTE: If you did not install the SL 500, this Black Air Line with the Red Connector would plug into the right side of the Air Regulator.

• Plug in the other Air Line with the Red Connector of the “Y” into the right side of the Air Regulator.

• Plug the Air Line coming off the Left side of the Air Regulator into your main air supply via 1/4” NPT female connector, or the quick disconnect, whichever type you purchased.

• Your air compressor should have at least 100 - 120 PSI.

• Shown below is the black threaded fitting connected to a 1/4” NPT female adaptor.

• It is suggested that Teflon tape be used on the threads of the black fitting to reduce possible air leakage.

• Strap your Air Regulator, glass bowl down to the left large wall bracket or left stand side with cable ties provided in your Tool Kit, making sure not to crimp any of the Air Lines.
