How to replace the drive belt in a Pro Tech band saw

  • Unplug the band saw’s power cord from the wall outlet.
  • Open the upper and lower cabinet doors. Rotate the blade’s quick-release lever to release the blade tension. Loosen the top and bottom mounting screws on the drive motor and pivot the motor inward to release the drive belt tension. Remove the drive belt from the motor pulley.
  • Use snap ring pliers to remove the C-clip from the lower wheel shaft. Slide the lower wheel off its shaft and remove the drive belt. Position the drive belt on the lower wheel pulley and, while sliding the wheel onto the shaft, wrap the drive belt over the motor shaft. Reinstall the C-clip on the lower wheel shaft. Push the drive motor outward to apply tension to the drive belt and tighten the mounting screws on the drive motor.
  • Reposition the blade on the upper and lower drive wheels. Rotate the blade quick release lever to apply blade tension. Close the cabinet doors. Restore power.

What to do when your Pro Tech band saw makes ragged cuts

Using a dull blade or the wrong type of blade in a band saw produces ragged cuts, as does feeding the work piece through the cutting area too quickly. The blade also can't make clean cuts if blade tension is loose.

Move the work piece slowly through the cutting area to help the blade cut smoothly. Pushing the work piece too fast can cause the blade to twist-resulting in cuts with tattered edges. If you have to push the work piece with more than just light force to move it through the cutting area, make sure the blade is sharp. Replace a dull blade because it will produce ragged cuts and won't cut the work piece efficiently.

Check blade tension if tattered edges appear on cuts when moving the work piece through the cutting area slowly and with light tension. Tighten blade tension if you can easily push the blade in more than a 1/4-inch using a gloved finger.

Using the wrong type of blade on a work piece can cause ragged cuts, so use the right type of blade for the work piece you're cutting. For example, using a 6 TPI (Teeth Per Inch) saw blade to cut thin plywood veneer will typically result in cuts with ragged edges. Use a thin-kerf blade with at least 60 TPI to cut thin plywood veneer cleanly.
