Assemble the attachment onto the end of your shop vacuum. Typically the attachment you’ll want to use will be a long rectangular piece. This is meant to cover the entire cutting area.
Clip the vacuum onto the top of your saw with the mouth piece as close as possible to where the wood will be cut.
Plug in the vacuum and turn it on whenever you are sawing wood.
Empty the vacuum bag at the end of your project and dispose of the wood dust.
