Make sure the machine is connected to an outlet having the same configuration as the plug.
4 CARTON CONTENTS 1. 2. 3. 4. 5. 6. 7. 8. 7 Band Saw with Pulleys attached Large V-Belt Small V-Belt Motor Pulley 3/4" to 5/8" Reducing Bushing Belt and Pulley Guard Clamp Key Belt and Pulley Guard 6 5 1 2 8 3 ASSEMBLY OPTIONAL STAND The optional stand is shipped top-down in the shipping container with the motor mounted to the inside top of the stand. The on/off switch is wired to the end of the power cord. To make the motor operational, do the following: 1. Remove the stand (A) Fig.
ATTACHING BAND SAW TO THE OPTIONAL STAND The band saw is very heavy. Use a helper when attaching the saw to the stand. Attach the band saw to the optional stand using the four holes provided (two are shown at (A) Fig. 7). Place one 5/16 -18 x 13/4" hex head screw with one 5/16" flat washer through each hole through the bottom of the band saw and the top of the stand, and attach with a 5/16" lock washer, and 5/16-18 hex nut.
B A Fig. 12 Fig. 11 ATTACHING THE SWITCH A push-button switch (mounted in a switch box) and a cord set are supplied with the unit. To attach the switch to the band saw arm: DISCONNECT MACHINE FROM POWER SOURCE. The on/off switch-to-motor cord (F) Fig. 11 is tied to the vertical mounting post (G) opposite the motor pulley. The cable tie (H) prevents the switch-to-motor cord (F) from contacting the belt or motor pulley during operation. IMPORTANT: LEAVE THIS CABLE TIE IN PLACE.
STARTING AND STOPPING SAW K K L M Fig. 17 Fig. 18 To start the machine, press the “START” button (K) Fig. 17. To stop the tool, press the “STOP” button (L) Fig. 17. When the machine is not in use, the switch should be locked in the “OFF” position to prevent unauthorized use, using a padlock (M) Fig. 18 with a 3/16" diameter shackle B A A Fig. 20 Fig. 19 TABLE INSERT Place the table insert (A) Fig. 19 in the hole provided in the table.
A A B D C Fig. 23 Fig. 24 Fig. 25 ADJUSTING BLADE TENSION DISCONNECT MACHINE FROM POWER SOURCE. A series of graduations is located on the back of the upper wheel slide bracket. These graduations indicate the proper tension for various widths of blades. With the blade on the wheels, turn the knob (A) Fig. 23 to raise or lower the wheel, until the red fiber washer (D) Fig. 25 is in line with the proper graduation for the size of the blade used.
3. Adjust the guides (A) Fig. 28, so that the front edge of the guides are just behind the “gullets” of the saw teeth. The complete guide block bracket can be moved in or out by loosening the thumb screw (C) Fig. 28 and turning the knurled knob (D) Fig. 28. When F the guides (A) are set properly, tighten thumb screw (C). G 4. Two set screws (B) Fig. 28 hold the upper blade guides (A) in H place. Loosen the set screws (B) to move the guides (A). Place E them as close as possible to the side of the blade.
BELT AND PULLEY ARRANGEMENTS FOR ALL EIGHT AVAILABLE SPEEDS Fig. 32 Fig. 33 With the longest belt on the inside groove of the motor pulley (B) Fig. 32 and on the drive pulley (C), and the small belt in one of the remaining three grooves of the motor pulley and the corresponding groove of the gear box pulley (E), speeds of 40, 60, 85, and 3000 SFM are readily available. To obtain speeds of 40, 60, and 85 SFM, push the shifter knob (F) Fig.
Trouble: BAND SAW DOES NOT COME UP TO SPEED. Probable Cause 1. Low voltage due to improper extension cord size. 2. Low voltage. Remedy 1. Replace with adequate size cord. 2. Contact an electrician. 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.
OPERATING THE BAND SAW DISCONNECT MACHINE FROM POWER SOURCE. Before starting the machine, make all adjustments and put all guards in place. Turn the upper wheel clockwise by hand to be sure that everything is correct before providing power to the tool. Keep the top guide close to the work. Do not force the material against the blade. Light contact with the blade will permit easier following of the line and will prevent excess friction, heating, and work-hardening of the blade at its back edge.

CHANGING THE BLADES 1. 2. 3. 4. 5. DISCONNECT MACHINE FROM POWER SOURCE. Open the upper and lower wheel guards. Release tension on the saw blade. Loosen the table alignment pin with a wrench and pull out. Remove table insert. Take the blade off the wheel, and guide it through the slot in the table. Install the new blade by reversing the procedure. Table alignment pin should be re-seated by gently tapping it with a hammer. LUBRICATION The gear case is filled at the factory with 1-1/2 quarts of oil.
