The Blade Keeps Coming Off.. How Do I Adjust The Blade On My D28770 Band Saw

1. Tension: Make sure the blade is properly tensioned. Adjust the tension by using the tension adjustment knob or lever according to the manufacturer's instructions. A properly tensioned blade is less likely to come off during operation.

2. Blade tracking: Check the blade tracking to ensure it's properly aligned on the wheels. Use the tracking adjustment knob to make small adjustments to the blade's position on the wheels.

3. Blade guides: Inspect the blade guides to ensure they are properly positioned and not causing the blade to veer off track. Adjust the guides as needed to keep the blade running true.

4. Wheel alignment: Check the alignment of the upper and lower wheels. If they are not aligned, adjust them according to the manufacturer's recommendations.

5. Blade condition: Inspect the blade for any signs of damage or wear. If the blade is worn or damaged, it may not stay on the wheels properly. Replace the blade if necessary.

Always refer to the owner's manual for specific instructions on adjusting and maintaining your band saw. If you're unsure about making these adjustments, it's best to consult a professional or contact Dewalt customer support for assistance.

1. Check the Tires:

Worn or damaged tires can cause the blade to track inconsistently and eventually derail. Examine the tires for any cracks, tears, or uneven wear. If the tires are worn, replace them with new ones of the correct size and type for your saw.

Make sure the tires are properly inflated according to the manufacturer's recommendations. Underinflated tires can cause the blade to wobble and increase the risk of derailing.

2. Align the Wheels:

Although external adjustment isn't available, ensuring proper wheel alignment is crucial for blade tracking. Check the user manual for your specific model to find instructions on aligning the wheels. This usually involves loosening and tightening certain set screws or bolts to adjust the position of the wheels relative to each other.

Some users have reported success with slightly tilting the upper wheel slightly towards the back of the saw to improve blade tracking. However, proceed with caution and double-check the alignment with a level or straightedge before using the saw.

3. Tension the Blade:

Proper blade tension is essential for smooth tracking and cutting performance. Consult the user manual for the recommended blade tension range for your saw. Use the blade tension knob to adjust the tension until it falls within the recommended range.

Avoid over-tensioning the blade, as this can put unnecessary stress on the blade and wheels and increase the risk of breakage.

4. Use the Correct Blade:

Ensure you're using the correct blade type and size for your intended cutting material. Using the wrong blade can cause tracking issues and reduce cutting performance.

Make sure the blade is properly welded and free of any defects. A damaged blade is more likely to derail.

5. Check for Other Issues:

If the above steps don't resolve the issue, there might be other factors at play. Look for any loose components, worn bearings, or damage to the blade guides or other parts of the saw that could affect blade tracking.

If you're unsure about the cause or uncomfortable troubleshooting further, consult a qualified technician for professional repair or diagnosis.

Remember, safety is paramount when working with power tools. Always unplug the saw before making any adjustments and wear appropriate safety gear like gloves and eye protection.

I hope these tips help you get your DeWalt D28770 bandsaw back on track and cutting smoothly!
