There is also a wireless remote. It's yellow and is usually near the ShopBot. The SawStop has a switch box as well.

=== Measure Filter Back Pressure ===
 +
The clear plastic tube mounted near the filter stack is a manometer.  When the collector is running, the distance between the left and right columns of the manometer should be two inches or less.  If it exceeds this, flow through the filter will be reduced and it must be cleaned.  When the filter is clean, the back pressure will be less than 1.25".

=== Clean the filter ===
 +
Turn off the main switch at the top of the rack to be sure the collector won't start up while you're working on it.  Remove the white plastic cap on the bin at the base of the filter stack.  Scoop out the dust with your hand and into a bucket.  This dust will be very fine - try not to breath it.  Don't use a vacuum to clean the bin.  The fine dust will go through most vacuum filters.

Use a combination of tapping and compressed air to dislodge dust from the filter pleats.  You can tap with your hands or a plastic mallet on the outside of the filter.  Don't get too crazy or you will dent the filter.  Tap all around and the whole length.  Two or three minutes of tapping will probably be enough unless the filter is really dirty.  Compressed air from the hose reel above the assembly table can also be used. Spray the air all around the filter, keeping the nozzle an inch away from the mesh of the filter.  Closer than that or using > 90 psi air pressure can damage the filter material.
