DO NOT OPEN HOOD''' to push start as we did in recent past. Just push start button and adjust feed speed. | |||
Stay tuned for more detailed instructions for use. | |||

== Usage Notes == | |||
*Do not use if conveyor belt is not centered. Belts are expensive and will destroy themselves if they drift too far in either direction. | |||
*For oily or dense woods (tropical hardwoods, etc), take only very light passes to prevent clogging the sandpaper. | |||
*Always remove dried glue squeeze outs with a scraper or other tool before coming here. | |||
*DO NOT USE unless glue has fully dried | |||
*Use a belt cleaner occasionally to refresh the sandpaper | |||
*Do not use to remove old finishes. | |||
=== Abrasive Dimensions === | |||
If you need to cut a new abrasive from the roll and tracing the old one isn't convenient, use the dimensions below. | |||
[[File:Supermax 25x2 abrasive dimension.png]] | |||
(not to scale!) | |||
# From one square cut edge, measure 12' and cut another square edge. You now have a strip of abrasive 144" long and 4" wide. | |||
# Measure 13.5" from one end and make a mark on the back of the paper. Trace this line to the nearby end's opposite corner, making a diagonal. This 13 1/2" x 4" right triangle defines the first "tail." Cut along this diagonal to make the first end pointy. | |||
# Measure 3.5" from the point. Draw a line perpendicular to the diagonal edge. Cut this off to make the pointy end stubby. | |||
# Repeat this procedure on the other end **but on the opposite edge.** That is, make a (blunted) rhombus, not a trapezoid. You now have two tails on your long strip, one "facing up" and one "facing down." | |||
# Refer to the video on how to install this into the machine. | |||
== Safety == | == Safety == | ||
This sander features overload detection. If the machine detects too high a load, it will automatically slow down the feed. This saves wear and tear on the machine, but may cause burning of the workpiece if you cut too aggressively. | |||
*The height adjustment on this machine is VERY aggressive. A full turn will raise the table by more than 2mm (a typical cut should be < .5mm). '''PLEASE USE A MAXIMUM OF 1/8 TURN OF THE HEIGHT WHEEL PER PASS!''' | |||
* Make your first cuts with a very slow speed (10 or less). Once you are sure the load is OK you can gradually increase the speed on subsequent passes. | |||
*When overload detection kicks in, a red light next to the speed control will turn on. '''IF YOU SEE THIS LIGHT, PLEASE REDUCE YOUR DEPTH OF CUT AND/OR FEED RATE!''' | |||
*Like all of our other sanders, sleeves must be above the elbow, and no gloves should be worn. It's pretty easy to get pulled into the rollers. | |||
