  • Page 4: Additional Safety Rules For Band Saws

    11. NEVER START THE MACHINE with the workpiece against the blade. 12. HOLD WORKPIECE FIRMLY against the table. DO NOT attempt to saw a workpiece that does not have a flat surface against the table. 13. HOLD WORKPIECE FIRMLY and feed into blade at a moderate speed.

  • Page 5: Power Connections

    A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should be pro- tected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-prong ground- ing type plugs and matching receptacle which will accept the machine’s plug.

    (See (B) Fig. 7) before loosely tightening the carriage bolts (D). Further alignment will be necessary after the saw is attached to the stand. Carefully turn the stand right side up. ASSEMBLY Fig. 4 Fig.
  • Page 8 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 1- 3/4"...
  • Page 9 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.

  • Page 10: Starting And Stopping Saw

    STARTING AND STOPPING SAW Fig. 17 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.

  • Page 11: Adjusting Blade Tension

    These graduations are correct for average work, and will not be affected by rebrazing of the saw blade. Use these graduations until you become familiar enough with the operation of the band saw to vary the tension for different kinds of blades or work.

  • Page 12: Adjusting Lower Blade Guides And Blade Support Bearing

    When using the machine for metal cutting (40, 60, 85, 115, 160, 220, and 335 SFM), push the shifter knob (A) Fig. 31 all the way in, disengaging the clutch (B) from the hub (C) of the pulley. An additional clutch (D) is located inside the band saw. It must be engaged with the hub (E) of the gear that transmits power through the gear box.

  • Page 13: Troubleshooting Guide

    Except for the one speed of 115 SFM, both belts may be left on the machine, regardless of the blade speed. Even though a band saw is well-maintained, problems can occur. This troubleshooting guide can help you solve the more common problems: Trouble: SAW WILL NOT START.
  • Page 14 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.

  • Page 15: Operating The Band Saw

    When withdrawing the blade, be careful not to draw the blade off of the wheels. In most cases, it is easier and safer to turn the workpiece and saw out through waste material. Do not back the blade out while the saw is running.

  • Page 16: Band Saw Blades

    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.

  • Page 17: Changing The Blades

    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.
