As a proud owner of a Dewalt orbital sander, I understand the importance of knowing how to use and troubleshoot it. The Dewalt D26451 is a 5-inch sander with a 3 Amp, 12,000 RPM motor, making it a powerful tool for sanding projects. It is a random orbit sander, which means it moves in a circular motion while simultaneously spinning around its axis. This motion ensures an even finish on the surface being sanded.

One of the key features of the Dewalt D26451 is its variable speed control. This allows you to adjust the speed of the sander based on the type of material you are sanding. For example, a higher speed may be needed for tougher materials, while a lower speed may be more appropriate for delicate surfaces. The variable speed control is located on the top of the sander and can be easily adjusted with your thumb.

Another important feature of the Dewalt D26451 is its dust collection system. The sander is equipped with a dust bag that collects the dust and debris generated during sanding. It is important to empty the dust bag regularly to prevent it from becoming too full and hindering the performance of the sander.

When using the Dewalt D26451, it is important to keep in mind that it is a power tool and should be used with caution. Always wear appropriate safety gear, including eye protection and a dust mask. Additionally, make sure the material being sanded is securely clamped down to prevent it from moving or shifting during sanding.

In the next section, I will cover some common troubleshooting tips for the Dewalt D26451 orbital sander.

As a professional woodworker, I have come across several common problems that can occur with DeWalt orbital sanders. In this section, I will discuss these problems and provide practical solutions to fix them.

Problem: The Sander is Not Spinning

If your DeWalt orbital sander is not spinning, there could be several reasons for this problem. First, ensure that the power cord is connected correctly and not damaged. If the power supply is stable, the problem might be with the motor. In this case, you may need to replace the motor.

Another common cause of this problem is a worn-out sanding pad. Over time, the sanding pad can become worn out and lose its grip on the sandpaper. In this case, you will need to replace the sanding pad.

Problem: The Sander is Not Collecting Dust

If your DeWalt orbital sander is not collecting dust, this could be due to a clogged dust collection system. To fix this problem, you need to clean the dust collection system thoroughly. Start by removing the dust bag or canister and emptying it. Then, use compressed air to blow out any dust or debris that may be clogging the system.

Problem: The Sander is Vibrating Too Much

If your DeWalt orbital sander is vibrating too much, this could be due to several reasons. First, check the alignment of the sanding pad. If it is not aligned correctly, it can cause the sander to vibrate excessively. You can fix this problem by adjusting the alignment of the sanding pad.

Another common cause of excessive vibration is a worn-out sanding pad. If the sanding pad is worn out, it can cause the sander to vibrate excessively. In this case, you will need to replace the sanding pad.

Problem: The Sander is Not Sanding Smoothly

If your DeWalt orbital sander is not sanding smoothly, this could be due to several reasons. First, check the alignment of the sanding pad. If it is not aligned correctly, it can cause the sander to sand unevenly. Adjust the alignment of the sanding pad to fix this problem.

Another common cause of this problem is a worn-out sanding pad. If the sanding pad is worn out, it can cause the sander to sand unevenly. In this case, you will need to replace the sanding pad.

Maintaining Your Sander

As a proud owner of a DeWalt orbital sander, I know how important it is to maintain it properly to ensure its longevity and optimal performance. Here are a few tips to help you maintain your sander:

Cleaning

Regular cleaning of your sander is essential to keep it in good condition. Dust and debris can clog the sander’s motor and reduce its efficiency. I recommend cleaning the sander thoroughly after every use. Use a soft brush to remove dust and debris from the sander’s body and a compressed air canister to blow out any debris that may have accumulated inside the sander.

Replacement Parts

If you notice that your sander is not working as it should, it may be time to replace some parts. DeWalt discontinued the D26451 model, but replacement parts can still be found online. Make sure to purchase genuine DeWalt replacement parts to ensure the best performance.

Dust Collection

Dust collection is an important feature of the DeWalt orbital sander. The dust bag or dust shroud collects the dust and debris generated during sanding. Make sure to empty the dust bag or clean the dust shroud after every use. A clogged dust bag or shroud can reduce the efficiency of the sander and cause the motor to overheat.

Sanding Disks

The sanding disk is the part of the sander that comes into contact with the surface being sanded. Over time, the sanding disk can become clogged with dust and debris, reducing its effectiveness. I recommend using hook and loop sanding disks, which are easy to replace and can be reused several times. Make sure to use the correct grit for the job at hand.

Screws

Check the screws on your sander regularly to ensure that they are tight. Loose screws can cause the sander to vibrate excessively, reducing its efficiency and causing damage to the sander’s body.

By following these simple tips, you can keep your DeWalt orbital sander in top condition and ensure that it performs at its best every time you use it.

When it comes to electrical issues with your DeWalt orbital sander, there are a few things to keep in mind. First and foremost, make sure that your sander is properly plugged in and that the power source is working correctly. If you’re using an extension cord, make sure that it’s the appropriate length and gauge for your sander’s power requirements.

If your sander won’t turn on, the first thing to check is the switch. Make sure that it’s in the “on” position and that it’s functioning properly. If the switch is fine, check the power supply. If there’s a tripped breaker or blown fuse, that could be the culprit.

Another potential electrical issue is stripped wires. Over time, the wires in your sander’s cord can become damaged or stripped, which can cause the sander to stop working. Make sure to inspect your sander’s cord regularly for any signs of damage. If you notice any stripped wires, it’s important to replace the cord as soon as possible.

Finally, make sure that all of your sander’s connectors and terminals are properly connected. Loose connections can cause your sander to stop working or to work improperly. Check all of your connectors and terminals regularly to make sure that they’re tight and secure.

In summary, when troubleshooting electrical issues with your DeWalt orbital sander, make sure to check the power source, switch, circuit, power supply, tripped breaker, stripped wire, cord length, connectors, and terminals.
