4. The third hole is at the rear of the machine. An alternate method of securing the scroll saw to a supporting surface is to fasten the scroll saw to a mounting board. Then securely clamp the mounting board to a stand or workbench using two or more C-clamps. NOTE: For proper stability, the holes in the mounting board must be countersunk at the bottom so that the fastener heads are flush with the bottom surface of the mounting board. Fig. 4 A OPERATION OPERATIONAL CONTROLS AND ADJUSTMENTS STARTINg AND STOPPINg SCROLL SAW Make sure that the switch is in the "OFF" position before plugging cord into outlet. Do not touch the plug’s metal prongs when unplugging or plugging in the cord. The on/off switch (A) Fig. 5 is located on the right side of the scroll saw base. To turn the machine "ON", move the switch up to the "ON" position. To turn the machine "OFF", move the switch (A) down to the "OFF" position. LOCkINg SWITCH IN THE "OFF" POSITION IMPORTANT: When the machine 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 (B) and pull it out of the switch (Fig. 6). With A B Fig. 5 the switch toggle (B) 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 (B). In the event of a power outage (such as a breaker or fuse trip), always move the switch to the "OFF" position until the main power is restored. An accidental start-up can cause injury. B Fig. 6 VARIABLE SPEED SWITCH The scroll saw is equipped with a variable speed control (B) Fig. 5. The variable speed range is 600 to 1650 strokes per minute. When the variable speed knob (B) Fig. 5, is rotated all the way to the left (counterclockwise) the speed will be 600 strokes per minute. To increase the speed, rotate knob (B) to the right (clockwise) until the desired speed is obtained. When the knob (B) is rotated all the way to the right (clockwise) the speed will be 1650 strokes per minute. 10 ADJUSTINg BLADE TENSION Disconnect machine from power source. A Fig. 7 A Fig. 8 A B Fig. 9 Tension is applied to the blade when the blade tension lever (A) Fig. 7, has been adjusted and is in the vertical position as shown. When the blade tension lever (A) is moved to the horizontal position, as shown in Fig. 8, blade tension is released. To adjust blade tension, position lever (A) in the vertical position, as shown in Fig. 7. To increase tension, turn lever (A) clockwise and to decrease tension turn lever (A) counterclockwise. When adjusting tension, turn lever one- quarter of a turn at a time. NOTE: It is necessary to adjust the blade tension only when the blade is removed from both the upper and lower blade holders and a new or different type of blade is used. 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. After desired tension is obtained, position tension lever (A) in the horizontal position, as shown in Fig. 7. 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. 8, the blade should start to have tension (resistance) when the blade tension lever is half way between open Fig. 8, and closed Fig. 7 positions. Finer blades require more tensioning while thicker blades require less tension. ADJUSTINg CLAMPINg ACTION OF UPPER AND LOWER BLADE HOLDER CHUCk Disconnect machine from power source. Different widths of scroll saw blades will make it necessary to adjust the clamping action of the upper and lower blade holders. It should be noted, however, that very little adjustment is necessary and very little clamping force is required to hold the blade satisfactorily. As a rule of thumb, looking down at the table with the table insert slot in the 6 o’clock position, resistance on the blade locking lever should be felt when the upper blade locking lever reaches the 7 o’clock position, or when the lower blade locking lever reaches the 5 o’clock position. 1. Move the blade locking lever (A) Fig. 9, to the rear (open) position, as shown. 2. Turn chuck clamping knob (B) Fig. 9, clockwise to tighten and counterclockwise to loosen the clamping action of the blade holder chuck. Very little movement of knob (B) will be necessary. NOTE: Only the upper chuck is shown. Clamping action of the lower chuck is adjusted in the same manner and can be accessed by removing dust cup shown in Fig. 24. 11 1111 TILTINg THE TABLE Disconnect machine from power source. A Fig. 10 Fig. 11 A B Fig. 12 B C Fig. 14 B C The table on your scroll saw can be tilted 45° to the left for bevel cutting operations by removing the dust cup as shown in Fig. 24 and loosening table lock knob (A) Fig. 10, tilt the table to the desired angle indicated on degree scale (B) Fig. 11 and tighten lock ...
