Resumen del manual
Place a 1/4" flat washer onto a 1/4-20x1/2" hex head screw and insert screw through hole in pulley guard and thread screw into the tapped hole in the casting. Repeat this process for the remaining hole. Raise the motor and assemble the belt (D) Fig. 7, to the desired steps of the two pulleys then release the motor. A speed selection chart (E) is located on the inside of the guard cover. When the belt is tensioned, tighten screws (C). FASTENING BAND SAW TO SUPPORTING SURFACE IF DURING OPERATION THERE IS ANY TENDENCY FOR THE BAND SAW TO TIP OVER, SLIDE OR WALK ON THE SUPPORTING SURFACE, THE RIGHT LEG OF THE BAND SAW MUST BE SECURED TO A SUPPORTING SURFACE. Align the hole in the “L” shaped floor mounting bracket (A) Fig. 8, with the hole in the bottom of the right leg (B). Insert a 5/16” flat washer (C) onto a 5/16-18x1/2” hex head screw (D). Insert screw through the floor mounting bracket (A) and the right leg. Place a 5/16” flat washer (E) onto the screw (D) and tighten securely. Repeat this process for the remaining hole on the other side of the right leg. Then secure the two brakcets to the supporting surface.

The on/off switch (A) Fig. 13 is located on the front of the band saw. To turn the machine “ON,” move the switch up to the “ON” position. 2. To turn the machine “OFF”, move the switch (A) down to the “OFF” position. B B MAKE SURE THAT THE SWITCH IS IN THE “OFF” POSITION BEFORE PLUGGING IN THE POWER CORD. IN THE EVENT OF A POWER FAILURE, MOVE THE SWITCH TO THE “OFF” POSITION. AN ACCIDENTAL START-UP CAN CAUSE INJURY. LOCKING SWITCH IN “OFF” POSITION IMPORTANT: When the machine is not in use, the switch should be locked in the “OFF” position to prevent unauthorized use, using a padlock with a 3/16" diameter shackle through the holes at (B) FIg. 13. AUTOMATIC SHUT-OFF When the band saw is in the horizontal position, the saw should shut itself off automatically. After a completed cut has been made, and the saw is in the down or horizontal position, the shut-off bracket (B) Fig. 14 will contact the toggle switch (A) and push it to the down position, turning off the power. IMPORTANT: THE SHUT-OFF BRACKET (B) SHOULD NOT REST ON OR BE SUPPORTED BY THE TOGGLE SWITCH (A). The downward travel of the saw should be adjusted to just trip the toggle switch at its lowest position. To adjust the downward travel of the saw arm, loosen lock nut (C) Fig. 15, and turn the stop screw (D) in or out until the correct adjustment is made; then tighten lock nut (C). A Fig. 13 B A Fig. 14 D C Fig. 15 ADJUSTING BLADE TENSION DISCONNECT MACHINE FROM POWER SOURCE. 1. Turn blade tension handwheel (A) Fig. 16, clockwise to increase or counterclockwise to decrease blade tension. Correct tension is obtained when the blade is just tight enough that no slippage occurs between the blade and the wheels. A 2. When the machine is not in use, release the blade Fig. 16 tension. 11 ADJUSTING BLADE TRACKING 1. Place the saw arm in the vertical position and open the wheel cover (A) Fig. 17. 2. Turn on the band saw. The blade is tracking properly when the back of the blade (B) Fig. 17, is just touching the edge of the wheel flange (C). The back of the blade should not be rubbing against the flange. 3. If an adjustment is necessary the blade guide bearings and blade support bearings (E) Fig. 19 (two of which are shown) should be clear of the blade. 4. Loosen screw (D) Fig. 18. 5. With the band saw running, turn adjusting screw (E) until the blade is tracking properly making certain blade tension is maintained by turning blade tension knob. (F). The blade is tracking properly when the back side of the saw blade just touches the flange on the wheel. 6. Tighten screw (D) Fig. 18, when adjustment is complete. 7. IMPORTANT: IT IS POSSIBLE WHEN MAKING THIS ADJUSTMENT TO OVER TIGHTEN THE ADJUSTING SCREW (E), FIG. 18, AND CAUSE THE BLADE TO BE MIS-ALIGNED. If this happens, loosen the adjusting screw (E) several turns but do not remove it from its threaded hole and loosen screw (D). Turn screw (D) clock-wise until it stops but do not tighten. Then turn the adjusting screw (E) clockwise until it bottoms. Turn on the machine and turn adjusting screw (E) clockwise a small amount at a time until the blade is tracking correctly and tighten screw (D) Fig. 18. 8. After the blade is tracking properly make sure to adjust the blade guide bearings and blade support bearings. ADJUSTING BLADE SUPPORT BEARINGS DISCONNECT MACHINE FROM POWER SOURCE. 1. The blade support bearing (A) Fig. 19, should be adjusted so it just touches the back of the saw blade after the blade is tracking properly. To adjust, loosen screw (C) and move the bracket (D) up or down until the support bearing (A) just touches the back of the blade (B). Then tighten screw (C). 2. Adjust the other blade support bearing in the same manner. B C A Fig. 17 Fig. 18 D E F D C A B E...
