# Empty Sandblast media separator

### Empty the Media Separator Drawer

Behind the Plasma table is a square gray machine that is the media separator for the sand blaster.

There is a drawer on the bottom with two retaining latches.

1. Put on a dust mask and safety glasses
2. Ensure the sandblaster is off
3. Pull and release the red lever on the right side of the filter a few times to knock loose fine particles from the filter.
4. Check the vent ducting from the booth to the separator, ensure it's not filled with media.
5. Empty the bottom drawer into the dumpster
6. Use the Powder coating shopvac vacuum out the inside around the filter tubes and drawer box.

## Safety

- Wear a dust mask.
- Wear safety glasses.

## Inspect/Rotate Nozzle

1. Unplug the sandblaster
2. Find a 1/8" Allen key in the maintenance cart.
3. Unlock the carbide nozzle at the front end of the spray gun using the allen key, so that it can be removed.
4. Take note of the nozzle position, in the end, we will want to reinstall the nozzle 1/4 turn further.
5. Remove the nozzle and inspect for wear on the part that is inside the gun. If the wear is getting bad, let maintenance know.
6. Rotate the carbide nozzle 1/4 turn clockwise (as looking down the barrel - but don't actually look down the barrel).
7. Lock the carbide nozzle in place using the Allen key.

## Inspect the Spray Gun and Tube

Inspect all around the body of the spray gun and the tube below it for holes. The steel tube can wear through on the back side of the 45º bend, on the part that faces the cabinet.

If any holes are found, red tag the sandblaster and file a maintenance report.

## Check the Media Level

A small amount of media is better than overfilled. There only needs to be about 6" of media in the bottom the cabinet. If it looks low or over filled, contact the area lead for the Sand Blaster.

## Notes

Rotating the nozzle extends the life of the nozzle.

# Sandblaster - Deep clean

## Safety

## Clean Siphon Tube

1. Remove the siphon tube via the two screws at the top. (Be careful and avoid dropping the screws.)
2. Inspect the siphon tube for holes and file a tool report if any are visible.
3. Blow compressed air through the siphon tube to dislodge any caked on abrasive and dirt.
4. Reinstall siphon tube.

## Clean Media

1. Place a bucket under the bottom gate of the cabinet.
2. Open the gate to drain out the media.
3. Tap the sides of the hopper with a soft mallet to get any remnants out. (We don't need the hopper completely clean.)
4. Take the buckets and a sifter outside.
5. Pass the material through the sifter to remove and debris.
6. Discard debris in the dumpster.
7. Dump the sifted media back in the cabinet.

## Test Hopper Motor

1. Turn on the machine.
2. Verify hopper motor under the cabinet is active and vibrating. If it isn't running, file a tool report.
