Anleitung Zusammenfassung
8. Replace the blade guard, (removed in STEP 2), and the table alignment screw (removed in STEP 4). Tighten both securely. ALWAYS MAKE SURE THE UPPER Fig. 36 BLADE GUARD IS INSTALLED AND PROPERLY ADJUSTED BEFORE OPERATING THE BAND SAW. 9. Close the doors (B) Fig. 35 before operating saw. 10. To use the miter gage as shown in Fig. 40, insert the miter gage guide bar into miter gage slot (S) Fig. 37 and adjust it to the desired angle. Fig. 35 G A A B E C D Fig. 37 F S A Fig. 38 DUST PORT A dust port (A) Fig. 38, is provided to connect your band saw to a standard shop vacuum or dust collector. The opening of the dust port is 2-1/4" I.D. 17 USING THE BAND SAW Before starting the machine, see that all adjustments are properly made and the guards are in place. Turn the upper wheel by hand to make sure that everything is correct BEFORE turning on the power. Keep the top guide within 1/8" of the work piece at all times. Do not force the material against the blade. Light pressure on the work piece will produce a smoother cut, and prevent excess friction, heating, and hardening of the blade. KEEP THE SAW BLADE SHARP. Very little forward pressure is required for normal cutting. Keep the workpiece moving at a slow and consistent rate against the blade to ensure a smooth and accurate cut. Avoid twisting the blade by trying to turn sharp corners. Remember, you must saw around corners. CUTTING CURVES When cutting curves, turn the stock carefully so that the blade follows without twisting. If a curve is so abrupt that it is necessary to repeatedly back up and cut a new kerf, a narrower blade, a blade with more set, or additional relief cuts Fig. 39, may be necessary to allow the blade to cut more efficiently. The more set a blade has, the easier it will allow the stock to be turned, but the cut is usually rougher than where a medium amount of set is used. When withdrawing the piece being cut, changing the cut, or for any other reason, be careful not to accidentally draw the blade off the wheels. In most cases, it is easier and safer to turn the stock and saw out through the waste material, rather than try to withdraw the stock from the blade. Fig. 39 Fig. 40 illustrates a typical cross-cutting operation using the miter gage. Notice how the upper blade guide assembly (A) is set slightly above the work surface (B).

Fig. 42 Fig. 42 illustrates a typical resawing application using the accessory rip fence. 19 TROUBLESHOOTING GUIDE In spite of how well a band saw is maintained, problems can occur. The following troubleshooting guide will help you solve the more common problems: Trouble: SAW WILL NOT START. Probable Cause 1. Saw not plugged in. 2. Fuse blown or circuit breaker tripped. 3. Cord damaged. Trouble: BREAKER KICKS OUT FREQUENTLY. Probable Cause 1. Extension cord too light or too long. 2. Feeding stock too fast. 3. Blade in poor condition (dull, warped, gummed). 4. Low voltage supply. Trouble: BAND SAW VIBRATES EXCESSIVELY. Probable Cause 1. Machine not mounted securely to stand. 2. Stand on uneven surface. 3. Worn belt. 4. Pulley not aligned. 5. Motor not fastened securely. Trouble: BAND SAW DOES NOT COME UP TO SPEED. Probable Cause 1. Low voltage due to improper extension cord size. 2. Low voltage. Trouble: BLADES BREAK. Probable Cause 1. Blade not tensioned properly. 2. Blade guides improperly adjusted. 3. Blade support bearing improperly adjusted. 4. Blade wheel tracking adjustment improperly set. 5. Bad weld on blade. 6. Worn tires. 7. Forcing wide blade around short radius. 8. Dull blade or insufficient set. 9. Upper blade guide set too high. 10. Continuous running of machine when not actually cutting. Remedy 1. Plug in saw. 2. Replace fuse or reset circuit breaker. 3. Have cord replaced. Remedy 1. Replace with adequate size cord. 2. Feed stock more slowly. 3. Clean or replace blade. 4. Contact an electrician. Remedy 1. Tighten all mounting hardware. 2. Reposition on flat level surface. 3. Replace belt. 4. Adjust pulleys. 5. Tighten all mounting hardware. Remedy 1. Replace with adequate size cord. 2. Contact an electrician. Remedy 1. Adjust blade tension. 2. Check and adjust blade guides. 3. Adjust blade support bearing. 4. Check and adjust blade tracking. 5.
