Step 1: Remove the upper sidecar panel retention screws

The air metering valve is located in the sidecar on the right side of the machine. Using a T20 Torx driver, loosen and remove the 12 T20 Torx screws securing the upper sidecar panel to the Fuse Blast. Set the screws aside.

Step 2: Remove the lower sidecar panel retention screws

The lower sidecar panel must be moved slightly to free the upper sidecar panel. Using a T20 Torx driver, loosen and remove the five T20 Torx screws shown above. Set the screws aside. Do not remove the two screws at the bottom of the lower sidecar panel.

Step 4: Partially secure the lower sidecar panel

Thread at least one of the lower sidecar panel retention screws back into the lower sidecar panel to avoid inadvertently bending it.

Step 1: Disconnect the outlet hose from the cyclone separator

Using a small flat-blade screwdriver, loosen the hose clamp from the top of the cyclone separator. Gently lift the tubing off of the cyclone separator and drape it to the side. Be careful not to break the grounding connection to the tubing.

Step 2: Attempt to open the electronics box

Continue to Removing the motherboard and display assembly. If you find it difficult to to open the electronics box and access the motherboard, return here and remove the entire cyclone separator.

Step 1: Disconnect hoses from the cyclone separator

Using a small flat-blade screwdriver, loosen the hose clamps from the cyclone separator. Pull the pressure tap hose off of the cyclone separator. The pressure tap is located close to the front of the machine. If the pressure tap tube is difficult to remove or has deformed from use, it can be cut at the barbed fitting with a utility knife.

Step 2: Remove the cyclone separator retention nuts

Using a 7 mm nut driver or box wrench, loosen and remove the four hex nuts securing the cyclone separator to the Fuse Blast. Set the nuts aside. Move the two grounding wires out of the way of the cyclone separator.

Step 3: Uninstall the cyclone separator

Remove the cyclone separator and the gasket below it from the machine. Set them aside on a clean surface.

Step 1: Disconnect the pressure tap tubes

Disconnect the pressure tap tubes from the electronics box. If the pressure tap tubes are difficult to remove or have deformed from use, you can cut them at the barbed fittings with a utility knife.

Step 2: Remove the electronics box cover

Using a T20 Torx driver, loosen and remove the four T20 Torx screws securing the electronics box cover. Set the screws and cover aside. Do not remove any other screws at this time.

Step 3: Disconnect the cables from the motherboard

Disconnect all cables from the motherboard except for the two ribbon cables on the right side connecting the display panel to the motherboard. Using a spudger, unplug the Wi-Fi coaxial cable from the system on module (SOM).

Refer to step 3 in the section Installing the replacement motherboard and display assembly for a reference table of cables and motherboard ports.

Step 4: Unscrew the motherboard and display assembly mounting screws

Using a T20 Torx driver, loosen and remove the four T20 Torx screws securing the motherboard and display assembly to the Fuse Blast. Hold the box in place while you remove the screws.

Step 5: Remove the motherboard and display assembly

Loosen the four 7 mm hex standoffs securing the motherboard and display assembly to the Fuse Blast. You may need to use a 7 mm box wrench to start but should be able to loosen the standoffs by hand afterward. Move the assembly away from the front panel as you go, and set the standoffs aside as they are able to be removed. Once the motherboard and display assembly is fully free, set it aside for disposal with electronic waste.

Step 1: Mount the new motherboard and display assembly

Place the motherboard and display assembly in position and thread each standoff into place until firmly seated.

Step 2: Secure the motherboard and display assembly

Thread one T20 Torx screw into each of the four standoffs. Using a T20 Torx driver, tighten until snug.

Step 3: Reconnect all cables to the motherboard

Reconnect the cables to the motherboard. Follow the image and table here to ensure that each cable is connected to the correct port on the motherboard.

Step 1: Mount the cyclone separator gasket

Place the cycle separator gasket on the cyclone separator mount, aligning the holes in the corners of the gasket with the threaded posts.

Step 2: Mount the cyclone separator

Place the cycle separator on the gasket, aligning the holes in the corners of the cyclone separator base with the threaded posts.

Step 3: Secure the cyclone separator

Mount the two grounding wires on two of the cyclone separator posts. Thread one 7 mm nut onto each of the posts. Use a 7 mm nut driver or box wrench to tighten the nuts until they are secure but the gasket is not fully compressed.

Step 4: Reconnect hoses to the cyclone separator

Press the cyclone pressure tap tube (labeled 0) onto the tap at the top of the cyclone separator. Reinstall the air/media outlet hose and the cyclone outlet hose to the cyclone separator. Tighten the hose clamps using a 6.5 mm slotted screwdriver.

Step 1: Reconnect the outlet hose to the cyclone separator

Slip the cyclone outlet hose onto the top of the cyclone separator. Tighten the hose clamp using a 6.5 mm slotted screwdriver.

Step 1: Remove the lower sidecar panel retention screws

Use a T20 Torx driver to loosen and remove any lower sidecar panel retention screws you previously reinstalled. Set the screws aside. Do not remove the two screws at the bottom of the lower sidecar panel.

Step 3: Secure the upper sidecar panel

Thread one upper sidecar panel retention screw into each of the 12 screw holes in the upper sidecar panel. Use a T20 Torx driver to tighten until snug.

Step 4: Secure the lower sidecar panel

Thread one upper sidecar panel retention screw into each of the five open screw holes in the lower sidecar panel. Use a T20 Torx driver to tighten until snug.
