Some illustrations in this Instruction Manual may show details or attachments that differ from those on your own power tool NAME OF PARTS: (Fig. 1a) (Fig. 1b) SPECIFICATIONS: 3 1/4-INCH BELT SANDER ET-3303-J: Motor Single-Phase, Series: Wound Commutator Motor Power Source Single-Phase 115V AC/DC 60Hz Sanding Belt Size 3”x21” (76mmx533mm) Input 950W No-Load High 1475ft/min (450m/min) Belt Speed Low 1180ft/min (360m/min) Weight 10.8 lbs. (4.9kg) 3 1/4-Inch Belt Sander Operator's Manual Operation APPLICATIONS: -Sanding finish and flooring finish of woodwork products. -Base polishing of Lumber-coated planes. -Sanding finishes of metal surfaces. -Base polishing of metal-coated planes, rust removal, or paint removal to refinishing. -Surface finish of slate, concrete, and so on. PRE-OPERATION: Before using the Electric Power Tool, complete the following preparations. CAUTION: CONFIRM THE FOLLOWING POINTS PRIOR TO CONNECTING THE PLUG TO THE POWER SOURCE. 1. Confirm the applied power source: Be sure to operate the Electric Power Tool in the voltage specified on the name plate. 2. Confirm that the power switch is turned "OFF": If the plug is connected to the power receptacle while the power switch is turned "ON", the machine starts operating unexpectedly, inviting serious accidents. Prior to using the Electric Power Tool, be sure to confirm that the power switch is turned "OFF". 3. Extension cord: When the work area is far away from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as possible. CAUTION: DAMAGED CORD MUST BE REPLACED OR REPAIRED. 4. Confirming condition of the environment: Confirm that the work site is placed under appropriate conditions conforming to prescribed precautions. 5. Confirm the power receptacle: If the power receptacle only loosely accepts the plug, the receptacle must be repaired. Contact the nearest electric store for repair service. If such a faulty receptacle is used, it may cause overheating, resulting in a serious hazard. 6. Attach sanding belt: For details, refer to the item “HOW TO HANDLE SANDING BELT” PRECAUTIONS ON USING BELT SANDER 1. Align the inside arrow mark of the sanding belt with the revolving direction of the drive pulley. 2. Sanding by impact and cutting by side-of-belt contact should be avoided. 3. Be careful of sanding sparks. 4. After operation, sweep the sanding dust away from the dust bag to avoid serious accidents. 5. Don’t use water, or oil as lubricant. 6. Ascertain that the sanding workpiece contains neither nails nor other harmful foreign matter. 7. Sanding glass fiber not recommended. 8. After operation, blow away the dust on the belt and the pulleys. 3 1/4-Inch Belt Sander Operator's Manual Operation OPERATION: HOW TO USE THE BELT SANDER: 1. How to adjust sanding position: Push switch and turn sanding belt to check position. Adjust sanding belt so that both edges protrude 1/6” 1/ 8” (1.6mm-3mm) past edges of pulleys. If sanding belt is operated too far on the inside, it may cause abrasion and damage machine. Adjust sanding belt position by turning adjust screw (Fig. 2). -Turn adjust screw clockwise to move belt in. -Turn adjust screw counterclockwise to move belt out. CAUTION: IF SANDING BELT MOVES DURING (Fig. 2) OPERATION, ADJUSTMENT CAN BE MADE WHILE IN OPERATION. 2. To turn on switch: Turn on switch while holding machine away from surface to be worked on. If machine is placed on surface when switch is pushed, surface may be badly scratched. The same applies when stopping the machine. 3. How to hold the machine: Grasp handle and handle knob and hold machine against surface to be worked on so that it contacts surface lightly. Weight of machine itself is sufficient for sanding and polishing at highest efficiency. Do not apply any additional pressure, for this would place unnecessary load on motor, shortening life of sanding belt and lower work efficiency. 4. How to move machine: Move machine forward first and then backward, repeating this motion. 5. How to select the proper sanding belt: Choose sanding belt of proper grain size and grain type for your specific purpose, by referring to the tables below (Table 1 and Table 2): Derived finish Proper grain size Coarse finish 30-40 Medium finish 40-100 Semi fine finish 80-240 Fine finish 180-400 Table 1 Grain type Surface to be worked on AA Steel, wood WA Wood, bamboo CC Nonferrous metals, slate, plastics, concrete Table 2 CAUTIONS: -FOR GRAIN SIZE, REFER TO TABLE ABOVE. -SANDING BELT GRAIN SHOULD BE COARSER THAN SANDPAPER USED FOR MANUAL WORK. -USE SANDING BELT OF SAME SIZE GRAIN UNTIL UNIFORM SURFACE IS OBTAINED. CHANGING GRAIN SIZES MAY RESULT IN POOR FINISH. 3 1/4-Inch Belt Sander Operator's Manual Operation OPERATION (CONTINUED): 6. How to change belt speed: Either high speed or low speed operation can be selected according to the materials or the operating conditions. Selecting sanding belt operating speed can be achieved by shifti...
