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.
ADDITIONAL SAFETY RULES FOR BAND SAWS 1. IF you are not thoroughly familiar with the operation of band saws, obtain advice from your supervisor, instructor, or some other qualified person. 2. Make sure wiring codes and recommended electrical connections are followed and that tool is properly grounded.. 3. Make sure that the saw blade teeth point downward toward the table. 4. Adjust the upper guide about 1/8" above the work. 5. Make sure that the blade tension and blade tracking are properly adjusted. 6.
1. All grounded, cord-connected tools: 2. Grounded, cord-connected tools intended for use on a supply circuit having a nominal rating less than 150 volts: In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug.
OPERATING INSTRUCTIONS FOREWORD Delta Models 28-293 and 28-299 are 14" Band Saws. These tools are equipped with a 1 HP, 115V guarded drip-proof motor inside an enclosed stand. Included with each saw is a push button switch, a blade and belt guard, an arbor and motor pulleys with a V-belt, blade guides, a wood cutting blade, and an instruction manual. UNPACKING AND CLEANING Carefully unpack the tool and all loose items from the shipping container(s).
B ATTACHING MOTOR PULLEY Attach the motor pulley (A) Fig. 7 to the motor shaft, making sure that the set screw (B) in the motor pulley engages with the key (C) in the motor shaft. NOTE: The key is shipped taped to the motor. Remove it, place it on the motor shaft and then attach the pulley over it. A C Fig. 7 A B A ATTACHING BAND SAW TO THE STAND CAUTION: The band saw is very heavy. Use a helper when attaching the saw to the stand.
ATTACHING THE SWITCH A push-button switch (mounted in a switch box), and a cord set are supplied with the unit. To attach the switch to the band saw arm, do the following: 1. DISCONNECT TOOL FROM POWER SOURCE. 2. CAUTION: The on/off switch-to-motor cord (F) Fig. 11 is tied to the vertical mounting post (G) opposite the motor pulley. This cable tie (H) prevents the switch-to-motor cord (F) from contacting the belt or motor pulley during operation of the unit. IMPORTANT: Leave this cable tie in place.
6. Remove the screw and cable clamp (E) Figs. 15 and 16 from the lower arm of the band saw. E Fig. 15 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. F 8. Attach the two side panels removed earlier. E Fig.
TABLE INSERT B 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 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). A A 2.
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.
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 C 2. Make sure that the bottom blade guides and support bearings are clear of the blade. B A 3. Check the upper blade guide assembly. The blade guides (A) Fig. 27 should be parallel to the blade.
BAND SAW BLADES A bandsaw blade is a delicate piece of steel that is subjected to a great deal of strain. 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.
