5. The band saw blade tension can be fined tune by turning adjustment nut (N) Fig. 51, while the blade is tensioned. B 6. A series of graduations is located on the back of the upper wheel slide bracket (T) Fig. 51. These graduations indicate the proper tension for various widths of blades. C T NOTE: THESE GRADUATIONS ARE CORRECT FOR AVERAGE WORK, AND WILL NOT BE AFFECTED BY REBRAZING OF THE SAW BLADE.
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: DISCONNECT MACHINE FROM POWER SOURCE B C 1. Make sure that the bottom blade guides and support bearings are not touching the blade. A 2. Check the upper blade guide assembly. The blade guides (A) Fig. 54 should be parallel to the blade.
ADJUSTING LOWER BLADE GUIDES AND BLADE SUPPORT BEARING B E A A B Adjust the lower blade guides and blade support bearing after the upper guides and bearing have been adjusted. C DISCONNECT MACHINE FROM POWER SOURCE. D 1. Adjust the front edge of the guide blocks (B) Fig. 56 so that they are just behind the “gullets” of the saw teeth. Turn the knurled knob (C) Fig. 56 to make this adjustment. Check the support bearing (D) Fig. 56. It should not be touching the back of the blade. Fig. 56 2.
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 Remedy 1. Switch cord / motor cord not plugged in. 1. Plug in switch cord / motor cord. 2. Fuse blown or motor reset tripped. 2. Replace fuse or push motor reset button. 3. Cord damaged. 3. Have cord replaced. Trouble: BREAKER OR MOTOR KICKS OUT FREQUENTLY. Probable Cause Remedy 1.
Trouble: BLADE WILL NOT TRACK. Probable Cause Remedy 1. Blade too loose 1. Adjust tension 2. Upper wheel not properly adjusted. 2. Adjust upper wheel. 3. Improperly adjusted blade support bearing. 3. Adjust blade support bearing. Trouble: CUT DOES NOT AGREE WITH SETTING ON THE TILT SCALE. Probable Cause Remedy 1. Pointer out of adjustment 1. Adjust pointer. Trouble: BLADE WILL NOT STAY ON WHEEL. Probable Cause Remedy 1. Blade not tensioned properly. 1. Adjust blade tension. 2.
BAND SAW BLADES A band saw blade is a delicate piece of steel that is subjected to tremendous strain. You can obtain long use from a band saw blade if you use it properly. Be sure you use blades of the proper thickness, width and temper for the various types of material and cuts. Always use the widest blade possible. Use narrow blades only for sawing small, abrupt curves and for fine, delicate work. This will save blades and will produce better cuts.
