PROHIBITED OPERATIONS Operating the machine without being checked out. Touch anything on this machine unless you know what it does. Adjusting the table height wheel more than 1/8 of a turn between passes. Using the machine as a surface planer to significantly reduce the thickness of a piece. (Use surface planer, jointer or bandsaw instead.) Sanding plywood, MDF, OSB and other manufactured materials. Removing glue, paper, coatings, finishes, paint, polyurethane, etc., from wood. (Sand bare wood only.) Sanding wet, sappy or resinous woods. Sanding glue-ups that have not dried at least 24 hours. (Always remove as much squeeze-out as possible before sanding. Glue can melt and ruin abrasive strips.) Sanding pieces that are less than 9 inches long or less than ¼ inch thick. Making adjustments other than the table height with the elevation wheel. Replacing sanding strips. (Unless you have received training in and practiced the procedure.)
IMPORTANT CONVEYOR BELT SWITCH The conveyor belt is controlled by the yellow switch behind the main power switch. Position the switch to OFF when turning the machine drums off and position it to FWD after turning the machine drums on. When sanding, use only the FWD position. The REV position is used only to help remove a workpiece that has become jammed in the machine.
CONVEYOR BELT SPEED Two speeds are available and are selected with the lever on the out-feed side of the machine. Move the lever only when the conveyor belt is in motion.
FEED ANGLE Work pieces having a width close to 25-inches must fed into the machine perpendicular to the drums, however, narrower pieces should be fed at an angle. Even a slight offset feed angle is highly desirable. Angling the workpiece minimizes concentrating abrasive load-ups and burning on narrow widths of the drums due to glue lines or mineral streaks in the stock and promotes more even wear of the strips. The optimum feeding angle is about 60º.
