A Step-By-Step Guide To Replacing The Blade On Your 9411 Band Saw

If you need to replace the blade on your Black and Decker 9411 band saw, there are several steps you should follow to ensure you do so safely and correctly. Firstly, make sure the band saw is unplugged and shut off. Then, open the upper and lower cabinet doors and release the blade tension by rotating the blade's quick-release lever. Remove the table levelling screw and open the blade cover. Now you can pull the blade out of the band saw. When positioning the new blade, ensure the teeth are pointing downwards and forward. Work the new blade into the cabinets and over the drive wheels, then close the blade cover and reinstall the table levelling screw. Finally, re-tension the blade and close the cabinet doors.

Shut off the electricity

Before you begin to replace the blade on your band saw, it is important to shut off the electricity to the device. This is a crucial safety step and will ensure that the band saw does not accidentally turn on while you are changing the blade.

To shut off the electricity, simply unplug the band saw's power cord from the wall outlet. This will cut the power supply to the band saw, ensuring that it cannot be turned on accidentally. Once you have done this, you can safely proceed with the rest of the blade replacement process.

It is worth noting that some band saws may have different power setups, and the above instructions may not apply to your specific model. Always refer to the manufacturer's instructions or seek expert advice if you are unsure about how to safely shut off the electricity to your band saw.

Release the blade tension

To replace the blade on a band saw, the first step is to ensure that the unit is disconnected from any power source. Open the upper and lower cabinet doors. Then, to release the blade tension, locate the tension knob on top of the band saw, typically on a vertical shaft above the upper cabinet. Loosen the tension by turning the knob, usually counterclockwise, until the blade is loose and pliable. This will allow you to proceed with removing the old blade and installing a new one.

The tension knob plays a crucial role in securing the blade in place and ensuring proper tension for effective cutting. By loosening the tension, you can release the blade from its taut position and prepare it for removal. Once the blade is loose, you can proceed with the next steps in the blade replacement process, such as raising the band saw blade guard and removing the rear blade guard.

It is important to follow safety precautions when working with power tools like band saws. Always make sure the unit is unplugged or disconnected from power before attempting any maintenance or repairs. This will help prevent accidental activation of the saw during the blade replacement process.

Remove the table levelling screw

To remove the table levelling screw from the front of the table of your band saw, follow these steps:

First, shut off the electricity by unplugging the band saw's power cord from the wall outlet. This is important for safety reasons.

Next, open the upper and lower cabinet doors to access the blade and other components.

Now, release the blade tension by rotating the blade's quick-release lever. This will make it easier to work with the blade and other parts.

After that, open the blade cover in the upper cabinet to access the blade and other internal components.

At this point, you can proceed to remove the table levelling screw. Make sure to keep it in a safe place so that you can reinstall it later if needed.

Once the screw is removed, you can pull the blade out of the band saw. Be careful when handling the blade, as it may have sharp edges.

It is important to note that the process of removing the table levelling screw may vary slightly depending on the specific model of your band saw. Always refer to the manufacturer's instructions or a qualified technician if you are unsure about any steps.

Install the new blade

To install the new blade, first, slide the blade through the slot in the saw table. Then, rotate the blade and place it over the top and bottom tires, centring it over the middle of each tire. Next, begin tightening the tensioning knob at the top of the band saw to secure the blade in position.

Do not over-tighten, especially if transitioning from a thin blade to a thick one or vice-versa. Check that the blade is tracking properly in the centre of the tires, then continue to tighten the tension adjustment knob. Rotate the top band saw wheel, watching to ensure the blade tracks in the centre of the tire. If the blade is tracking too far forward or backward, locate the tracking adjustment knob in the back of the band saw's upper cabinet and rotate it slightly while turning the wheel. Keep adjusting the tracking knob until the blade rides perfectly centred on the tire.

Once the blade is tracking properly, adjust the tension on the blade until the gauge's indicator is positioned for the proper blade thickness. A wider blade will require more tension than a thinner blade, but the indicator should have appropriate marks for every popular blade size.

Re-tension the blade

Once you have installed the new blade, you will need to re-tension it. This is done by first repositioning the blade on the upper and lower drive wheels. Then, rotate the blade's quick-release lever to apply tension to the blade.

It is important to not over-tighten the blade, especially if you are switching from a thin blade to a thicker one or vice-versa. Check to see that the blade is tracking properly in the centre of the tires. While tightening the tension adjustment knob, rotate the top band saw wheel, watching to ensure the blade tracks in the centre of the tire on the wheel.

If the blade is not tracking correctly, locate the tracking adjustment knob at the back of the band saw's upper cabinet. Rotate this knob slightly as you turn the wheel and observe the difference in the centring of the blade. Make small adjustments to the tracking knob until the blade is riding perfectly in the centre of the tire.

Once the blade is tracking properly, you can check the tensioning gauge on the back of the saw's upper cabinet to ensure the tension is correct for the blade thickness. A wider blade will require more tension than a thinner blade, and the indicator on the gauge should have marks for each blade size.
