OPERATING CONTROLS AND ADJUSTMENTS STARTING AND STOPPING 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 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 (C) Fig. 24 with a 3/16" diameter shackle. C Fig. 24 TILTING THE TABLE 1.
ADJUSTING THE TABLE STOP The tool 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). Check to see if the blade is 90 degrees to the table surface. If not, then do the following: 1. Tilt the table slightly to the right and tighten the table lock knobs. Fig. 27 2. Loosen the locknut (B) Fig.
TRACKING THE BLADE A CAUTION: DISCONNECT MACHINE FROM POWER SOURCE. IMPORTANT: Before tracking the blade, make sure that the blade guides and blade support bearings are clear of the blade. 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.
5. Two set screws (B) Fig. 35 hold the upper blade guides (A) in place. Loosen the set screws (B) to move the guides (A). Place them as close as possible to the side of the blade. (Be careful not to pinch the blade). Tighten the screws (B). B C 6. The upper blade support bearing (E) Fig. 35 prevents damage to the set in the saw teeth by keeping the blade from being pushed too far toward the back.
CHANGING BLADE SPEED FOR MODEL 28-206 ONLY 1. DISCONNECT MACHINE FROM POWER SOURCE. 2. Open the pulley guard (A) Fig. 37, by removing screw (B) and opening the pulley guard door. B 3. Lift and hold the motor up, place the belt on desired step of the pulleys, and release the motor. 4. The two motor speeds are 3300 fpm (feet per minute), and 2500 fpm. A Fig. 37 3300 fpm is the combination of the large motor pulley (3.15" dia) and the small saw pulley. This speed is for general work.
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.

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.
