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:
(continued on next page)
Trouble: SAW WILL NOT START.
Pr
obable Cause Remedy
1. Saw not plugged in. 1. Plug in saw.
2. Fuse blown or circuit breaker tripped. 2. Replace fuse or reset circuit breaker.
3. Cord damaged. 3. Have cord replaced.
Trouble: BREAKER KICKS OUT FREQUENTLY.
Pr
obable Cause Remedy
1. Extension cord too light or too long. 1. Replace with adequate size cord.
2. Feeding stock too fast. 2. Feed stock more slowly.
3. Blade in poor condition (dull, warped, gummed). 3. Clean or replace blade.
4. Low voltage supply. 4. Contact an electrician.
Trouble: BAND SAW VIBRATES EXCESSIVELY.
Pr
obable Cause Remedy
1. Machine not mounted securely to stand. 1. Tighten all mounting hardware.
2. Stand on uneven surface. 2. Reposition on flat level surface.
3. Worn belt. 3. Replace belt.
4. Pulley not aligned. 4. Adjust pulleys.
5. Motor not fastened securely. 5. Tighten all mounting hardware.
CUTTING CURVES
Turn the stock carefully so that the blade follows without twisting. For very abrupt curves, consider using a narrower
blade, or a blade with more set. Another solution to this problem is to make relief cuts (Fig. 39).
When you withdraw the workpiece or change the cut, be careful not to accidentally pull the blade off of the wheels.
The preference is to turn the stock and saw out through the waste material.
