20 Most Recent Dewalt Heavy - Duty 5" Random Orbit Sander - D26451 - Page 4 Questions & Answers

I've been using dewalt tools exclusively for 15 years. I've fixed numerous drivers, sawzals, etc. I've learn 3 things over and over again. 1 cleaning & lubing are grossly under rated, 2 if one part goes the rest are not far behind & 3 it has never cost me more than $20 to $30 bucks more to have the repair place rebuild it than to fix it myself. And most times they give you a new bulk packaged tool as a rebuilt. My recommendation: have it rebuilt...enjoy the new tool.

how old is the battery, test and recharge, if ok make sure is well oiled. May have to have it serviced if it is still low on torque.

I would suggest giving our Service Center so we can get your unit looked at. DEWALT com

Make sure the brads are not too small for the gun.

At least 12"

What model gun is this? Framing, finish, battery powered?

Power? circuit breaker? Plug? Owner's manual. Troubleshooting Does the motor hum? if so you have something jamed in the planer cutter.

Brushes can definitely cause this but unless you feel fairly confident in pulling the unit apart, it may be more cost effective to just replace it. It would be unusual to see the brushes wear out so quickly but I do not know how much you use it or the load you put it under. I have a Rigid that I use a LOT and have had it for probably 5 - 6 years and it is holding strong. These things just tend to last. I would contact DeWalt and see if you can have them send you new brushes first and then go for it; the worst is that you ultimately have to replace it (which you might have had to anyway) and the upshot is that you fixed it yourself and now have many more years and sawdust sneezes in your future.

is this a gas cartridge type of nailer? It could be the effects of gravity on the spray nozzle. try pushing down in normal position but dont fire it. quickly move to ceiling then try firing. I am not a fan of this type of nailer as they are problematic and finicky.

There a Youtube video on how to do this https://www.youtube.com/watch?v=8qDwehIi8CU

I think you have to call the service center on this one, http://www.dewalt.com/Find-Service-Center.aspx

5-10 drops directly in the air fitting before each use.

I think that model is on a ring internally so there isnt a way to do like the bigger ones, you would have to take the screws out and take in half and you will the the brushes and can replace.

The clutch is defective , you can get replacement parts from dewalt. There are several dewalt service centers in the US

To do the dew one must see the dew and then become the dew.

why would you want to take it a part?

Some power tools have a thermal reset switch built in. It sounds as if the thermal overload is faulty, or the unit has overheated. Check to insure the cooling ports of the motor are not clogged with sawdust.

Does your model have a warm and hotter switch? If it do it is the seitch...if only one it is the heating unit that is bad..good luck..

Most case just reverse the two leads on the motor.
