How to clean Dewalt reciprocating saw | Step by Step Guide:

Here are some steps to clean you saw:

Cleaning the blade:

Cleaning the blade is perhaps the most important part of cleaning a Dewalt reciprocating saw. If you’ve ever gotten anything stuck in the teeth of your reciprocating saw, then you know that it’s necessary to clean them thoroughly after each use. You can do this by hand or with an automatic blade cleaner (which has rotating brushes). Either way, be sure to brush away any debris and wipe down the blade with a dry cloth. 

What about other parts of my Dewalt reciprocating saw?

After you clean the blade, you can use a small amount of light machine oil or lubricating oil to remove any built-up grime on the outside of your tool. If it has been particularly dirty, then consider using paint thinner to break through tough grease. Finally, if there are any loose parts inside the housing, tighten them by hand so they don’t fall off during operation.  

Cleaning the Motor:

You shouldn’t have to clean the motor of your Dewalt reciprocating saw on a daily basis. However, if you notice that it is heating up after extended use or smells funny, then it’s time for deeper cleaning. Begin by disconnecting the power source and removing the blade guard. After that, spray compressed air into all intakes and exhausts on the blade housing until they are free of debris. 

Finally, remove any grime with paint thinner on a soft cloth or brush using light machine oil as needed. You can also take off each attachment piece of your Dewalt reciprocating saw (i.e., blades, blades guards) so you can individually hand wash them with warm water, soap, and a sponge to ensure thorough cleaning.

How to clean the housing of a Dewalt reciprocating saw?

After you clean your Dewalt reciprocating saw’s blade, it’s time to clean the outside of the housing. You can clean off any stubborn dirt or grime with paint thinner on a soft cloth. If your tool is an older model that uses oil instead of grease (and therefore has more built-up grime), then you can use paint thinner with light machine oil as an effective solvent. 

If there are any bolts or screws loose inside the housing, tighten them by hand before using your Dewalt reciprocating saw again. 

Why does my Dewalt reciprocating saw smell bad?

If cleaning the motor and other parts of your Dewalt reciprocating saw didn’t fix its smelly problem, then there could be an oil leak in either the blade housing or the motor area. If you notice any leaking fluids, then be sure to clean them up before using your Dewalt reciprocating saw again.

Does that pretty much cover it?

Yes! Completing these steps should have your Dewalt reciprocating saw looking and smelling like new, so you can get back to work with minimal wait time.
