INSTRUCTION MANUAL 14" Wood Cutting Band Saw GENERAL SAFETY RULES Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are certain hazards involved with the operation of the product. Using the machine with respect and caution will considerably lessen the possibility of personal injury. However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result. Safety equipment such as guards, push sticks, hold-downs, featherboards, goggles, dust masks and hearing protection can reduce your potential for injury. But even the best guard won’t make up for poor judgment, carelessness or inattention. Always use common sense and exercise caution in the workshop. If a procedure feels dangerous, don’t try it. Figure out an alternative procedure that feels safer. REMEMBER: Your personal safety is your responsibility. This machine was designed for certain applications only. Delta Machinery strongly recommends that this machine not be modified and/or used for any application other than that for which it was designed. If you have any questions relative to a particular application, DO NOT use the machine until you have first contacted Delta to determine if it can or should be performed on the product.

If not, loosen the screw (F) Fig. 21 and move the pointer to the correct position. Tighten the screw. ADJUSTING BLADE TENSION CAUTION: DISCONNECT TOOL FROM POWER SOURCE. A 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. 23 to raise or lower the wheel, until the red fiber washer (B) Fig. 23 is in line with the proper graduation for the size of the blade used. B 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. Fig. 23 9 A B C Fig. 25 Fig. 24 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. Adjust the blade guides and bearings according to the following instructions. C 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. B A If the guide assembly moves when lock knob (B) is loosened, tighten set screw (C) until movement stops.

To adjust, do the following: 1. DISCONNECT TOOL FROM POWER SOURCE 2. Make sure that the bottom blade guides and support bearings are clear of the blade. 3. Check the upper blade guide assembly. The blade guides (A) Fig. 27 should be parallel to the blade. To adjust, loosen the screw (B) and rotate the complete guide assembly (C). When the blade guides are parallel with the blade, tighten the screw (B). 4. Adjust the guides (A) Fig. 28 so that the front edge of the guides are just behind the “gullets” of the saw teeth. The complete guide block bracket can be moved in or out by loosening the thumb screw (C) and turning the knurled knob (D) Fig. 28. When the guides (A) are set properly, tighten thumb screw (C). 5. Two set screws (B) Fig. 28 hold the upper blade guides (A) in place. Loosen the set screws (B) to move the guides (A). Place them as close as possible to the side of the blade. (Be careful not to pinch the blade). Tighten the screws (B). 6. The upper blade support bearing (E) Fig. 28 prevents damage to the set in the saw teeth by keeping the blade from being pushed too far toward the back. The support bearing (E) should be set 1/64" behind the blade by loosening the thumb screw (F) and turning the knurled knob (G) to move the support bearing (E) in or out. 7. Adjust the blade support bearing (E) so that the back edge of the blade overlaps the outside diameter of the ball bearing by about 1/16". The bearing (E) is set on an eccentric. To change the position, remove the screw (H) and bearing (E) Fig. 28. Loosen the thumb screw (F), back out the knurled knob from the set screw. Remove the hex shaft from the hole, and rotate it to move the eccentric for the bearing. 8.

Proper blade care results in optimal performance. Always use blades of the proper thickness, width, and temper to correspond to the workpiece. Use the widest blade possible. Narrow blades should be reserved for small, abrupt curves and delicate work. When pressure is required to push a workpiece through the blade, either file and set the blade, or replace it. A broken blade can be welded or brazed, but if the blade has been work-hardened, it will soon break again. A good rule of thumb is to sharpen the blade after 4 hours of operation. Band saw blades will break because of the peculiar stresses to which they are subjected. However, many blades break because the operator (1) does not check the alignment and adjust the guides; (2) forces or twists the blade around a short-radius curve; (3) feeds the workpiece too fast; (4) allows the blade to become dull; (5) tightens the blade tension excessively; (6) sets the top blade guide too high; (7) uses a blade that has been improperly brazed or welded; and/or (8) runs the blade continuously when not cutting. Blades for the standard 14" Band Saw are 93-1/2" long. The saw can adjust to a maximum length of 94" and a minimum of 91-1/2". If the saw is equipped with the accessory Height Attachment, the blades should be 105" long. Maximum and minimum lengths are 106" and 103-1/2". OPERATING THE BAND SAW CAUTION: DISCONNECT TOOL FROM POWER SOURCE. Before starting the tool, make all adjustments and put all guards in place. Turn the upper wheel clockwise by hand to be sure that everything is correct prior to turning the tool on. Keep the top guide close to the work. Do not force the material against the blade. Light contact of the workpiece with the blade will permit easier following of the line and will prevent excess friction, heating, and work-hardening of the blade at its back edge. Keep the saw blade sharp and very little pressure will be required for average cutting. Avoid twisting the blade by turning abrupt corners. CUTTING CURVES When cutting curves, turn the stock carefully so that the blade may follow without being twisted. If a curve is so abrupt that repeated new kerfs are needed, then use either a narrower blade or one that has more set. The more set a blade has, the easier the stock is to turn. However, the cut is usually rougher than when using a medium set. When withdrawing the blade, be careful not to draw the blade off of the wheels. In most cases, it is easier and safer to turn the saw and saw out through waste material. Do not back the blade out while the saw is running. 12 ACCESSORIES A complete line of accessories is available from your Delta Supplier, Porter-Cable • Delta Factory Service Centers, and Delta Authorized Service Stations.
