Fig. 11 A B Fig. 12 C D Fig. 13 E Fig. 14 5. Use the two nuts and lockwashers (E) Fig. 14, removed in STEP 3, to fasten the switch box to the bandsaw arm (Fig. 14). 7 6. Remove the screw and cable clamp (E) Figs. 15 and 16 from the lower arm of the band saw. E Fig. 15 E F Fig. 16 7. Insert the switch cord (F) Fig. 16, into the clamp (E) (removed in STEP 6), and fasten the switch cord (F) to the bandsaw. IMPORTANT: Be certain to prevent contact between the on/off switch-to-motor cord (F) Fig. 16 and the motor pulley or belt. If necessary, adjust the cord, then tighten the cable tie (H) Fig.11. 8. Attach the two side panels removed earlier. K L Fig. 17 STARTING AND STOPPING SAW To start the tool, press the “START” button (K) Fig. 17. To stop the tool, press the “STOP” button (L) Fig. 17. LOCKING 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, using a padlock (M) Fig. 18 with a 3/16" diameter shackle. K M Fig. 18 8 TABLE INSERT Place the table insert (A) Fig. 19 in the hole provided in the table. Engage the protrusion on the insert in the indents (B) in the table. A B Fig. 19 TILTING THE TABLE 1. The table on the band saw can be tilted 45 degrees to the right and 10 degrees to the left. To tilt the table to the right, loosen the two locking knobs (A) Fig. 20, tilt the table to the desired angle as shown on Scale (D)., and tighten two locking knobs (A). 2. To tilt the table to the left, loosen the two locking knobs (A) Fig. 20, and tilt the table to the right until access to the table stop (A) Fig. 21 is gained. Remove the table stop (A) Fig. 19, and tilt the table to the left 10 degrees. Tighten the two locking knobs (A) Fig. 20. ADJUSTING THE TABLE STOP The tool is equipped with an adjustable table stop (A) Fig. 21 that allows the table to be set at 90 degrees to the blade. Tilt the table to the right until the table stop (A) Fig. 21 contacts the table. Place a square on the table against the blade (Fig. 22). Check to see if the blade is 90 degrees to the table surface. If not, then do the following: 1. Tilt the table slightly to the left and tighten the table lock knobs. 2. Loosen the locknut (B) Fig. 21 to free the adjustment nut (A) Fig. 21. Turn the adjustment nut (A) right or left to raise or lower the table stop, then tighten the locknut (B). 3. Lower the table. Check to see that the table is 90 degrees to the blade (Fig. 22). If it is, then hold the stop (A) Fig. 21 and tighten nut (B). 4. Adjust pointer, if necessary. A A Fig. 20 A B C Fig. 21 Fig. 22 9 A A A A Fig. 23 Fig. 24 ADJUSTING BLADE TENSION CAUTION: DISCONNECT TOOL FROM POWER SOURCE. A series of graduations is located on the back of the upper wheel slide bracket. These graduations indicate the proper tension for various widths of blades. With the blade on the wheels, turn the knob (A) Fig. 21 to raise or lower the wheel, until the red fiber washer (B) is in line with the proper graduation for the size of the blade used. These graduations are correct for average work, and will not be affected by rebrazing of the saw blade. Use these graduations until you become familiar enough with the operation of the band saw to vary the tension for different kinds of blades or work. IMPORTANT: OVER-STRAINING IS A COMMON CAUSE OF BLADE BREAKAGE AND OTHER UNSATISFACTORY BLADE PERFORMANCE. RELEASE THE TENSION WHEN THE TOOL IS NOT IN USE. B C D Fig. 25 TRACKING THE BLADE CAUTION: DISCONNECT TOOL FROM POWER SOURCE. IMPORTANT: Before tracking the blade, make sure that the blade guides and blade support bearings are clear of the blade. After applying tension to the blade, rotate the wheels slowly forward by hand and observe the blade’s movement. The blade (A) Fig. 24 should travel in the center of the upper tire. If the blade creeps toward the front edge, loosen the wing nut (B) Fig. 25, and tighten the thumb screw (C). This action draws the blade toward the center of the tire. If the blade creeps toward the back edge, turn the thumb screw in the opposite direction. Adjust the thumb screw (C) Fig. 25 only a fraction of a turn each time. NEVER TRACK THE BLADE WHILE THE TOOL IS RUNNING. After the blade is tracking in the center of the tires, tighten the wing nut (B) Fig. 25. VERTICAL ADJUSTMENT OF THE UPPER BLADE GUIDE ASSEMBLY CAUTION: DISCONNECT TOOL FROM POWER SOURCE. Readjust the blade guides and bearings according to the following instructions. Set the upper blade guide assembly (A) Fig. 26 as close as possible to the top surface of the workpiece. Loosen the lock knob (B) and move the guide assembly (A) to the desired position. A B Fig. 26 10 ADJUSTING THE UPPER BLADE GUIDES AND BLADE SUPPORT BEARING Adjust the upper blade guides and blade support bearings ONLY AFTER the blade has the correct tension and is tracking properly. To adjust, do the following: 1. DISCONNECT TOOL FROM POWER SOURCE 2. Make sure that the bottom blade guides and support bearings are clear o...
