SAFETY GUIDELINES - DEFINITIONS It is important for you to read and understand this manual. The information it contains relates to protecting YOUR SAFETY and PREVENTING PROBLEMS. The symbols below are used to help you recognize this information. Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
GENERAL SAFETY RULES READ AND UNDERSTAND ALL WARNINGS AND OPERATING INSTRUCTIONS BEFORE USING THIS EQUIPMENT. Failure to follow all instructions listed below, may result in electric shock, fire, and/or serious personal injury or property damage. IMPORTANT SAFETY INSTRUCTIONS 1. FOR YOUR OWN SAFETY, READ THE INSTRUCTION MANUAL BEFORE OPERATING THE MACHINE. Learning the machine’s application, limitations, and specific hazards will greatly minimize the possibility of accidents and injury. 14.
ADDITIONAL SPECIFIC SAFETY RULES FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS INJURY. 13. SUPPORT THE WORKPIECE firmly with a miter gauge, backstop, or work table when sanding with a belt. Hold the workpiece firmly. Loss of control of the workpiece can result in injury. 14. AVOID KICKBACK by sanding in accordance with the directional arrows. Feed the workpiece against the downward rotation side of the disc or the forward rotation of the belt. Loss of control of the workpiece can result in injury. 15.
POWER CONNECTIONS A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3prong grounding type plugs and matching receptacle which will accept the machine’s plug.
EXTENSION CORDS Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D-1 shows the correct gauge to use depending on the cord length.

ASSEMBLY For your own safety, do not connect the machine to the power source until the machine is completely assembled and you read and understand the entire instruction manual. ASSEMBLY TOOLS REQUIRED 1/8" Hex Wrench (Supplied) Phillips Screwdriver 6 Mm Hex Wrench (Supplied) Adjustable Wrench ASSEMBLY TIME ESTIMATE Less than one hour ADJUSTING THE BELT TENSION Your sander was shipped from the factory with the drive belt (A) Fig. 1 attached to both pulleys (B) and (C).
ATTACHING THE BELT AND PULLEY GUARD B A Attach the belt and pulley guard (A) Fig. 4 to the machine base using the two M6x1x30mm cheese head screws (B). Fig. 4 INSTALLING THE SANDING DISC PLATE B 1. Turn the 1/4-20 x 1/4" hex socket set screw (A) Fig. 5 counter-clockwise until it clears the hole (B) Fig. 5 in the sanding plate. A Fig. 5 C 2. Align the flat of the drive shaft with the set screw (A) Fig. 6 in the hub of the plate (B) and install the sanding disc plate (B) on the drive shaft.
ATTACHING THE SANDING DISC A 1. Clean the sanding disc plate (A) Fig. 8. 2. Peel the backing from sanding disc and press the disc (B) firmly into position all the way around the sanding plate (Fig. 8). B Fig. 8 ATTACHING THE LOWER COVER FOR THE SANDING DISC B Install the lower cover (A) Fig. 9 on the belt and pulley guard, using the three M4 x .7 x 12mm sheet metal screws (B). A Fig. 9 INSTALLING THE DISC SANDER TABLE 1. Thread an M8 x 1.25 x 20mm hex socket head screw (A) Fig.
ATTACHING THE DUST CHUTE Align the three holes in the dust chute (A) Fig. 12 with the three holes in the left side of the sanding base. Place an M5.3 flat washer on an M5 x .08 x 10mm pan head screw (B) Fig. 12. Insert the screw through the hole in the dust spout and thread it into the taped hole in the sander base. Repeat this process for the two remaining holes. B A Fig. 12 INSTALLING THE BACKSTOP ON THE SANDING ARM Install the backstop (A) Fig.
24 MIN 3. Alternately, you can secure the sander by fastening it to a mounting board 18" x 24" or larger. The diagram in Fig. 16 shows the size and center-tocenter distance of the holes that you will need to drill in the mounting board. l 18 MIN 5-1/2" l NOTE: For proper stability, countersink the holes underneath the mounting board so that the screw heads are flush with bottom surface. l 3/8" DIAMETER (4) HOLES 15-1/2" l Fig. 16 Fig. 17 4.
LOCKING THE SWITCH IN THE “OFF” POSITION IMPORTANT: When the tool is not in use, the switch should be locked in the “OFF” position to prevent unauthorized use. To lock the machine, grasp the switch toggle (A) and pull it out of the switch (Fig. 19). With the switch toggle (A) removed, the switch will not operate. However, should the switch toggle be removed while the saw is running, the machine can be turned “OFF,” but cannot be restarted without re-inserting the switch toggle (A). A Fig.
ADJUSTING THE BACKSTOP SQUARE WITH THE SANDING BELT DISCONNECT MACHINE FROM POWER SOURCE. 1. Before adjusting, move the belt tension lever (A) Fig. 23 all the way to the left to the "TIGHTEN" position. 2. Place a square (B) Fig. 24 on the sanding belt with one end of the square against the backstop. See if the backstop is square with the sanding belt. 3. Loosen the screw (C) Fig. 24 and adjust the backstop. B A C Fig. 23 Fig. 24 TILTING THE TABLE DISCONNECT MACHINE FROM POWER SOURCE.
ADJUSTING THE MITER GAUGE SLOT PARALLEL WITH THE SANDING DISC DISCONNECT MACHINE FROM POWER SOURCE. 1. Place an adjustable combination square on the table with the part (A) Fig. 27 in the miter gauge slot (B) to check the distance from the slot to the sanding disc. Check the other side of the disc in the same manner (Fig. 28). The distances should be the same. A B Fig. 27 Fig. 28 2. To adjust, loosen the three screws (B) Fig. 29 that fasten the table to the table mounting bracket and trunnion.
USING THE TABLE ASSEMBLY WITH THE SANDING ARM When you use the sanding arm (A) Fig. 31 in the vertical position, you can move the complete table assembly (B) from the disc unit to the belt unit. DISCONNECT MACHINE FROM POWER SOURCE. 1. Remove the backstop (C) Fig. 31. 2. Thread the M8 x 1.25 x 20mm hex socket head screw (D) Fig. 31 ONLY PART OF THE WAY into the base casting. 3. Loosen the screw (E) Fig. 31, and remove the table assembly (B) from the disc unit.
REPLACING THE SANDING BELT DISCONNECT MACHINE FROM POWER SOURCE. 1. Loosen the screw (A) Fig. 34 and remove the backstop (B). 2. Slide the tension lever (C) Fig. 35 to the right to release the tension on the sanding belt. Remove the sanding belt (D) from both sanding drums. 3. An arrow is printed on the back of the sanding belt to indicate the travel direction of the belt. Make certain that this arrow and the arrow on the machine match. Slide the new sanding belt over both sanding drums. 4.
MACHINE USE SURFACING OR EDGE SANDING WITH THE SANDING BELT Always use the backstop (A) Figs. 39 and 40 when surface-sanding (Fig. 39) or when edge sanding Fig. 40. Hold the workpiece firmly and keep your fingers away from the sanding belt. Keep the end of the workpiece against the backstop and move the workpiece evenly across the sanding belt. Apply only enough pressure to allow the sanding belt to remove material. Use extra caution when sanding very thin pieces. A A Fig. 40 Fig.
END SANDING WITH THE BELT When sanding the ends of wide workpieces, use the sanding belt with the sanding arm in the vertical position and the table assembly moved to the sanding belt (Fig. 43). See the sections “CHANGING POSITION OF SANDING ARM” and “USING TABLE ASSEMBLY WITH SANDING BELT”. For more accurate work, use the supplied miter gauge to move the work evenly across the sanding belt (Fig. 43).
MAINTENANCE KEEP MACHINE CLEAN LUBRICATION Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material. Apply household floor paste wax to the machine table and extension table or other work surface weekly.
