blahblahblah 21. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are careless acts that can result in serious injury. 22. Maintain a balanced stance at all times so that you do not fall or lean against the blade or other moving parts. Do not overreach or use excessive force to perform any machine operation. 23. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for which it was not designed.

If the Band Saw is to be hard-wired to a panel, make sure a disconnect is available for the operator. During hard-wiring of the Band Saw, make sure the fuses have been removed or the breakers have been tripped in the circuit to which the Band Saw will be connected. Place a warning placard on the fuse holder or circuit breaker to prevent it being turned on while the machine is being wired. Converting from 230 Volt to 460 Volt (Three Phase) To convert from 230 volt to

5. Remove the worn blade and install the new blade, making sure the teeth face downward where they pass through the slot in the table. 6. Use the tension handwheel to tighten the tension on the blade. 7. Proceed with “Blade Tension” and “Blade Tracking” before operating the band saw. Blade Tension Rotate blade tension handwheel to the right to increase tension on the blade, to the left to decrease tension on the blade. Initially, set the blade tension to correspond

7. When satisfied, return the upper and lower blade guides close to the blade. 8. Close upper and lower doors. Guide Post For effective cutting and for safety’s sake, there should be a minimum amount of space between the top of the workpiece and the bottom of the blade guides. Loosen the locking knob (see Figure 6) and rotate the handwheel (Figure 6) to raise or lower the guide post so that the guides clear the workpiece by about 3/16”.

Squaring Work Table with Blade 1. Place the table in horizontal position with “0” on the scale (Figure 11). 2. Place a machinist’s square on the table and against the blade as shown. 3. If the square is not flush against the blade, loosen the screw below the table (Figure 11) with a 26mm wrench (provided). 4. Tilt the table as needed until the square is flush with blade. Retighten the screw. 5. Make sure the pointer is set at “0” on the scale. If it needs slight adjustment, loosen F

6. After installing new belts, make sure they are tensioned properly. Work Lamp Bulb The Work Lamp uses a standard medium-base 60 watt bulb. Band Saw Operation Consult “Features and Terminology” on page 7 for identification of the controls. Unlock the control panel using the provided keys. Never operate the band saw without blade covers in place and secured. Blade Break-In Procedure New blades are very sharp and, therefore, have a tooth geometry that

3. Start the saw using the pushbutton. 4. Turn the speed setting handwheel (Figure 14) to the required speed. Turning the handwheel clockwise increases speed. Turning counterclockwise decreases speed. Rotate the speed setting handwheel only when the band saw is running. Evaluating Cutting Efficiency The best way to determine whether the blade is cutting efficiently is to observe the chips formed by the cutting. • If the chip formation is powdery, then the feed

IMPORTANT: If a blade has been cut by using snips, the ends of the blade must be ground square before welding them together, as shown in Figure 17. Removing Teeth In fine pitched blades, one or more of the teeth on each side of the cut may need to be removed by grinding so that the weld area of the blade is uniform and the teeth will be uniformly spaced. See Figure 16. Welding Figure 17 4. Carefully clean the ends of the blade which will contact the welder jaws. Remove any dirt,

The welder is designed for intermittent use. Repeated welding within a short period of time may cause the welder to overheat. 12. Remove the blade from the clamps, and carefully inspect it. The spacing of the teeth should be uniform and the weld should be located in the center of the gullet. Misalignment is easily noted at this time from the weld appearance. See Figure 19 for examples of incorrect welds. 13. If the weld is imperfect, refer to the trouble- shooting section on page 28

If the blade is thicker at the weld than at the rest of the blade, using the blade may damage the guides. 20. When grinding, do not hit the teeth, or grind deeper than the thickness of the blade; or burn or overheat the weld area. Be sure to remove flash from the back edge of the blade. Any flash or “stub” teeth which project beyond the normal set or height of the other teeth must be ground off. Clean Up It is very important that the clamp jaws be kept clean at

Gage Use the standard gage (blade thickness) except when the increased thickness of the workpiece decreases accuracy and width cannot be increased to compensate. Examples of heavy gage applications: 1. When radius cutting in thick materials. 2. When the maximum width usable on the machine still provides insufficient beam strength for the blade. (Beam strength is the blade’s resistance to compression caused by strong feeding or the type of material being cut). P
