Assembly To assemble your 50-142 sander: 1. Using 13mm wrenches, loosen the four motor mount hex bolts (Figure 6) so you can adjust the motor position in the next steps. 2. With assistance, position the belt housing assembly on the left side of the base, taking care not to pinch the power cords between the assembly and the base. Motor Mounting Hex Bolts 2 of 4 Fig. 06 3. Place the V-belt around both pulleys, and secure the belt housing assembly with the two M10-1.
Assembly 10. Rotate the disc until you can see the set screw through the hole on the back of the V-belt safety cover (see Figure 13) 11.

Assembly Mounting Sander Once you have confirmed that your machine is running properly, mount it to a workbench. The strongest mounting option is a "Through Mount" where holes are drilled all the way through the workbench, and hex bolts, washers, and lock nuts are used to secure the sander to the workbench. Another option for mounting is a “Direct Mount” where the machine is simply secured to the workbench with a lag screw.
Operations Disc Sanding CAUTION Always keep the workpiece on the left side of the wheel that rotates down toward the table. This will keep the workpiece from flying out of your hands due to kickback. Fig.24 To use the sanding disc: 1. DISCONNECT THE SANDER FROM POWER! 2. Adjust the angles of the disc sanding table and the miter gauge for your operation. 3. Connect the sander to power, turn it ON, and allow it to reach full speed. 4. Place the workpiece on the table and firmly Fig.25 5.
Operations Belt Sanding Use the sanding belt for the long, flat surfaces of the workpiece. NOTICE: To avoid the risk of kickback and personal injury, always keep the workpiece firmly on the table, and never sand the short side of the workpiece with the sanding belt. To use the sanding belt: 1. DISCONNECT THE SANDER FROM POWER! Fig.27 2. Using a protractor or other angle measuring tool, set the correct angle of the sanding belt table for your operation. 3.
Operations Changing the Sanding Belt Sanding Belt Direction Most sanding belts are designed to sand in only one direction and will have a direction arrow on the back of the belt. The 50-142 is designed so that the sanding belt travels downward to the sanding table. To change the sanding belt: 1. DISCONNECT THE SANDER FROM POWER! 2. Unscrew the two knobs from the sanding belt cover and remove the cover from the sander (see Figure 29). 3.
Adjustments Squaring Disc Table To square the sanding disc table: 1. DISCONNECT THE SANDER FROM POWER! 2. Place a machinist's square or other 90° measuring tool against the disc table and sanding disc (see Figure 31). 3. Loosen the table lock handle, adjust the table square with the sanding disc, then re-tighten the table lock handle. Fig.31 4. Loosen the Phillips head screw on the angle pointer, position the red scale pointer over the "0" mark on the angle scale, then retighten the screw.
