Connecting sander to power source The motor supplied with your sander is wired for operation at 115 Volts. IT MUST NEVER BE CONVERTED TO OPERATE AT 230 VOLTS ! Before connecting the motor cord to the power source, make certain the switch is in the OFF position and be sure that the electric current is of the same characteristics as stamped on the motor nameplate. Grounding instructions WARNING: The sander must be grounded while in use to protect the operator from electric shock.
Operating instructions Starting and stopping sander The on/off switch (see Figure 8) is mounted in a switch box on the right side of the sander base. Move the switch to the forward (ON) position to start the sander. Move the switch to the rear (OFF) position to stop the sander. Locking switch in the OFF position We recommend that the switch be locked in the OFF position when the sander is not in use. The switch can be locked by pulling the switch locking tab out of the switch toggle (see Figure 9).
Belt table adjustments The belt sander table can be tilted or moved in or out to accommodate the operation being performed. Loosen the locking handle to change the position of the table. Move the table to the desired position and tighten the locking handle. NOTE: The lock handle is spring loaded. Reposition the handle by pulling out on the handle and turning the handle on the serrated locking stud. Release the handle and turn the locking handle to tighten or loosen the table.
Disc table adjustments Adjusting the table angle WARNING: When making adjustments, make sure the motor is disconnected from the power source. WARNING: To avoid trapping the work or fingers between the table and sanding disc, the table edge should be positioned a maximum of 1/16inch from the sanding disc. The disc table is positioned at 90 degrees to the sanding disc for most operations (see Figure 14).
Changing abrasive belts (continued) Press down on the tracking knob to release belt tension (see Figure 18). Remove the belt from the three pulleys. Install the replacement belt. Replace side cover; secure the cover with two knobs. IMPORTANT: Some belts have a directional arrow printed on the inside of the belt. In these cases the belt must be installed so the directional arrow is in the same direction that the machine is running. The sanding belt travels down the front of the machine.
Changing abrasive discs (continued) Align the keyway in the disc hub with the key on the motor shaft (see Figure 22). Install the disc plate on the shaft. Position the disc so the face of the disc is even with the edge of the upper disc guard. Tighten the setscrew in the hub of the disc plate. If necessary, adjust the position of the upper disc guard. Loosen the screws and adjust the position of the upper disc guard. Replace the lower disc guard and the sanding disc table. Miter gauge Figure 22.
Typical operations (continued) Sanding aluminum on the disc unit with the table tilted and using the miter gauge as a guide (see Figure 26). NOTE: Always sand on the left (downward) side of the sanding disc, as shown. Sanding on the right (upward) side of the sanding disc could cause the workpiece to fly up which could be hazardous. Sanding outside curves on the belt unit with the platen removed (see Figure 27). Polishing using the accessory felt belt in place of the sanding belt (see Figure 28).
Typical operations (continued) Inside curves can be sanded on the upper sanding belt idler wheel (see Figure 30). The upper cover can either be hinged back or removed. Figure 30.
