A A Fig. 16 AB Fig. 17 C Fig. 18 10 TABLE INSERT The table insert (A) can be assembled to the saw table with the opening in the insert pointing to the front of the table, as shown in Fig. 19, or to the right as shown in Fig. 20. With the table in the level position, 90 degrees to the blade, the insert should be positioned, as shown in Fig. 19. This allows for the blade to be pivoted forward after it is unclasped from the top blade holder, enabling you to quickly insert the blade into the next hole in a pattern when doing inside-cutting. When tilting the table for bevel cutting operations the insert (A) should be positioned as shown in Fig. 20. This allows for clearance of the blade when the table is tilting. A Fig. 19 A Fig. 20 A table insert blank (B) Fig. 21, is supplied as standard equipment with your scroll saw and can be used when cutting very small workpieces to give added support to the bottom of the workpiece. Cut a slot into the blank and replace the standard insert (A) with the blank (B). The slot cut into the blank (B) will only be as wide as the blade giving maximum support to the bottom of the workpiece. AB Fig. 21 CHANGING BLADES 1. WARNING: DISCONNECT MACHINE FROM POWER SOURCE. 2. Remove table insert (A) Fig. 22, and release blade tension by pulling tension lever (B) forward, as shown. A B Fig. 22 11 3. Push chuck locking lever (C) Fig. 23, to the rear as shown. This will release the blade (D) from the upper chuck (E). C D E Fig. 23 4. Insert long end (F) Fig. 24, of quickset blade wrench into hole (G) in lower blade holder. This will align wrench (H) with blade holder screw (J). Fig. 24 G F J H 5. Fig. 25 illustrates the quickset blade changing wrench (K) engaged with the lower blade holder assembly. Turn wrench counterclockwise to loosen screw (J) Figs. 24 and 25, and remove blade from lower chuck. 6. Insert new blade into the lower and upper blade holders in the same manner, making certain the blade teeth are pointing down toward the table. 7. Tighten screw (J) Fig. 26, in lower blade guard assembly. 8. Push chuck locking lever (C) Fig. 23, to the foreword position, to lock the blade in the upper blade holder assembly. 9. Replace the table insert that was removed in STEP 2. 10. Apply blade tension by referring to the following section "ADJUSTING BLADE TENSION." K J Fig. 25 J Fig. 26 12 ADJUSTING BLADE TENSION Tension is applied to the blade when the blade tension lever (A) Fig. 27, is in the rear position, as shown. When the lever (A) is moved forward, as shown in Fig. 28, blade tension is released. When adjusting blade tension, lever (A) should be in the forward position, as shown in Fig. 28. To increase blade tension, turn knob (B) Fig. 28, clockwise and to decrease blade tension, turn knob (B) counterclockwise. NOTE: It is necessary to adjust the blade tension knob (B) only when the blade is removed from both upper and lower blade holders and a new or different type of blade is assembled to the holders. It is not necessary to adjust blade tension when the blade is removed and replaced in only the upper blade holder as in performing inside cutting operations. Adjusting the blade for proper tension is usually accomplished by trial and error. One method is to pull back on the blade tension lever (A) Fig. 28, the blade should start to have tension (resistance) when the blade tension lever is half way between open Fig. 28, and closed Fig. 27. Finer blades require more tensioning while thicker blades require less tension. ADJUSTING CLAMPING ACTION OF UPPER BLADE HOLDER Different widths of scroll saw blades will make it necessary to adjust the clamping action of the upper blade holder. It should be noted, however, that very little adjustment is necessary and very little clamping force is required to hold the blade. 1. Move the chuck locking lever (C) Fig. 23, to the rear (open) position, as shown. 2. Turn locknut (C) Fig. 29, clockwise to tighten and counterclockwise to loosen the clamping action of the, blade holder. Very little movement of locknut (C) is necessary. TILTING THE TABLE The table on your scroll saw can be tilted 45 degrees to the left for bevel cutting operations by loosening table lock handle (A) Fig. 30, tilt the table to the desired angle and tighten lock handle (A). A Fig. 27 AB Fig. 28 A C Fig. 29 A Fig. 30 13 When bevel cutting, the holddown (B) Fig. 31, can be adjusted to lay flat on the stock by loosening screw (C) and tilting the holddown (B) accordingly. Then tighten screw (C). C B Fig. 31 ADJUSTING THE TABLE 1. Loosen the table locking handle, and move the table all the way to the right. 2. Using a square (A) Fig. 32, check to see if the table is 90 degrees to the saw blade, as shown. A Fig. 32 3. If the table is not at 90 degrees to the blade, adjust the table accordingly making certain screw (B) Fig. 33, contacts bottom of table surface when table is 90 degrees to the blade. Screw (B) can be adjusted by loosening nut (C), thread screw (B) in or out the desired dista...
