Note: Tighten the mounting fasteners evenly to avoid warping or cracking the cast iron base.

Test Run

Once the bandsaw is in place, test run your machine to make sure it runs properly and is ready for regular operation. The test run consists of verifying the following: 1) The bandsaw motor powers up and runs correctly, and 2) the stop but- ton safety feature works correctly.

If, during the test run, you cannot easily locate the source of an unusual noise or vibration, stop using the machine immediately, then review Troubleshooting on Page 39.

If you cannot find a remedy, contact our Tech Support at (570) 546-9663 for assistance.

To test run the bandsaw:

1.Read and follow the safety instructions at the beginning of the manual, and make sure the machine is setup properly.

2.Clear all tools and objects used during setup away from the machine.

3.Make sure the blade is properly tensioned and the blade guides are positioned correctly (refer to Blade Tensioning on Page 29, and Adjusting Blade Guides on Page 31 for detailed instructions).

4.Connect the machine to the power source.
