Attach the remaining short brace to the opposite side of the stand in the same manner. 19. Align the four holes in the long brace (A) Fig.
ATTACHING THE SAW TO THE STAND 1. 2. 3. 4. 5. 6. 7. THE BAND SAW IS VERY HEAVY. Use a helper when you attach the saw to the stand. Place the band saw on top of the stand as shown in Fig. 17. NOTE: Confirm that the pulley is on the same side of the stand as the pulley guard. Align the four holes in the saw with the four holes in the top of the stand. Place an M8 lockwasher and a M8 flat washer on a hex head screw (M8x1.25x80mm). Insert the screw A through one of the holes (A) in the saw and the B stand.
CONNECTING MOTOR CORD TO SWITCH ASSEMBLY DISCONNECT MACHINE FROM POWER SOURCE! Insert the motor plug (A) Fig. 18B into the receptacle (B) of the switch-to-motor cord. B ATTACHING THE TABLE TO THE SAW 1. 2. Remove the band saw blade. Align the two table studs (A) Fig. 19 in the bottom of the table with the two holes in the trunnion assemblies (B). NOTE: Confirm that the slot (C) Fig. 19 is facing toward the front. 3. Place an M13 flat washer on the table stud and thread the table knob on the table stud.
OPERATION OPERATIONAL CONTROLS AND ADJUSTMENTS STARTING AND STOPPING THE SAW The power switch is located on the left side of the machine. To turn the machine “ON”, push the green start button (A) Fig. 23. To turn the machine “OFF”, push the red stop button (B). A B Fig. 23 LOCKING THE SWITCH IN THE “OFF” POSITION IMPORTANT: When the tool is not in use, the switch should be locked in the “OFF” position to prevent unauthorized use, using a padlock (Fig. 24) with a 3/16" diameter shackle. Fig.
ADJUSTING THE TABLE STOP This machine is equipped with an adjustable table stop (A) Fig. 26 that allows the table to be set at 90 degrees to the blade. Tilt the table (C) Fig. 26 to the left until the table stop (A) Fig. 26 contacts the table. Place a square on the table against the blade (Fig. 27). If the blade is not 90 degrees to the table surface: 1. Tilt the table slightly to the right and tighten the table lock knobs. Fig. 27 2. Loosen the locknut (B) Fig. 26 to free the adjusting screw (A) Fig. 26.
TRACKING THE BLADE DISCONNECT MACHINE FROM POWER SOURCE! IMPORTANT: Before tracking the blade, confirm that the blade guides and blade support bearings are clear of the blade. A After applying tension to the blade, rotate the wheels slowly forward by hand and observe the blade’s movement. The blade (A) Fig. 31 should travel in the center of the upper tire. If the blade creeps toward the front edge, loosen the wing nut (B) Fig. 32 and turn the thumb screw (C) clockwise.
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: DISCONNECT MACHINE FROM POWER SOURCE! 1. 2. 3. 5. 6. 7. 8. Confirm that the bottom blade guides and support bearings are not touching the blade. Observe the upper blade guide assembly. The blade guides (A) Fig. 34 should be parallel to the blade.
DUST PORT A A dust port (A) Fig. 36A enables you to connect your band saw to a dust collector. NOTE”: The dust port is 4" O.D. Fig. 36A CHANGING BLADE SPEED FOR MODEL 28-206 ONLY DISCONNECT MACHINE FROM POWER SOURCE! 1. Remove the pulley guard (A) Fig. 37 by removing screw (B). 2. Lift the motor, place the belt on the selected step of the pulleys (A) Fig;. 38, and release the motor. 3. The motor has two speeds: 3300 fpm (good for general work), and 2500 fpm (used for resaw work).
CUTTING CURVES Turn the stock carefully so that the blade follows without twisting. For very abrupt curves, consider using a narrower blade, or a blade with more set. Another solution to this problem is to make relief cuts (Fig. 39). When you withdraw the workpiece or change the cut, be careful not to accidentally pull the blade off of the wheels. The preference is to turn the stock and saw out through the waste material. TROUBLESHOOTING GUIDE For assistance with your machine, visit our website at www.
Trouble: BAND SAW DOES NOT COME UP TO SPEED. Probable Cause Remedy 1. Low voltage due to improper extension cord size. 1. Replace with adequate size cord. 2. Low voltage. 2. Contact an electrician. Trouble: BLADES BREAK. Probable Cause Remedy 1. Blade not tensioned properly. 1. Adjust blade tension. 2. Blade guides improperly adjusted. 2. Check and adjust blade guides. 3. Blade support bearing improperly adjusted. 3. Adjust blade support bearing. 4.
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. Use blades of 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.
MAINTENANCE KEEP MACHINE CLEAN LUBRICATION Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material. Apply household floor paste wax to the machine table and extension table or other work surface weekly.
