DISCONNECT THE SANDER FROM THE POWER SOURCE!

7.Insert the 2x4' wooden studs under the table for support, and with help, lift the table slightly and move it out of the rear of the machine.
8.Disconnect the limit switch, remove all mount- ing screws, and remove the emergency stop push-panel assembly.
9.Turn both tracking adjustment bolts coun- ter-clockwise five turns, remove one roller support, and slide the drum out of the table assembly.
10.Remove the old conveyor belt. Inspect roll- ers, bearings, table for wear and replace as required.
11.Install the new conveyor belt. Note: The belt is non-directional.
12.Install the front roller, the roller support, and turn both tracking adjustment bolts clock- wise equally so the conveyor belt becomes taught and does not hang loose. DO NOT OVERTIGHTEN the belt.
13.With a helper, install the table from the rear in a similar fashion as it was removed.
14.Install the table guides and both lower access panels.
15.Align the lead screw flanges with the marks made in Step 6, and install the hex bolts.
16.Install the table height limit switches so the upper switch clicks when the conveyor sur- face is 1⁄4" away from the sandpaper, and the lower switch clicks when the conveyor table is 1⁄4" higher than its lowest position. Make sure that you test your settings with the handwheel manually so you don't crash the table if incorrectly set the first time around.
17.With a helper, install the gearbox, vibration dampener washers, and mounting bracket.
18.Install the emergency stop push-panel assembly and the limit switch.
19.Start the conveyor motor and turn the con- veyor tracking bolts as required until the conveyor belt tracks straight without loading up on one side of the table.
