3.
Lift the access hatch in the work surface grate and inspect the bottom of the blasting
chamber. The parts catcher grate should be visible at the bottom of the chamber.
4. If there is significant build-up obstructing your view of the parts catcher, the parts catcher
is clogged and must be cleared of debris.
If debris on the parts catcher is impeding the flow or powder or blasting media through the
grate, clean it.
To clean the parts catcher:
1. If the Fuse Blast was recently in use, wait for any powder plumes to settle.
2. Tap the fan icon on the Fuse Blast touchscreen to turn on the blower fan.
3. Unlatch and open the blasting chamber door.
4. Lift the access hatch on the work surface grate to access the parts catcher.
5. If there is visible debris on the parts catcher but no accumulated blasting media, remove
the debris from the parts catcher with a gloved hand. If the blasting media has accumulated
and obscures the parts catcher, proceed to the next step.
6. Using a gloved hand, feel through the media to the parts catcher mesh at the bottom. Run
your hand over the parts catcher to dislodge any debris. The blasting media should drain
freely when the obstructions are cleared.
7. If the blasting media still is not draining freely, use a scoop to remove the majority of the
accumulated media and transfer it to a container. Continue doing so until you can see and
dislodge the debris on the parts catcher.
8. If a scoop is not available, an anti-static grounded vacuum cleaner (such as an NFPA-652
compliant vacuum) can be used to clear the accumulated media.
9. When you next add fresh blasting media to the Fuse Blast or use it to clean printed parts,
ensure that blasting media and powder flow easily through the parts catcher.
