In general, to change the brushes, remove the blade. Then, remove the two screws that hold the brush caps in place. After that, pull out the old brushes and insert the new ones. Finally, replace the brush caps and screw them back in place.
In this post, I’ll show you how to do just that. So read on for step-by-step instructions on how to change the brushes on a Bosch reciprocating saw.
Tools and materials you’ll need

Here are some steps to change the brushes:
1. Remove saw blade guard
By lifting up the upper part of the blade guard, then pulling outwards.
2. Locate brush housing cap
The housing cap is located under the blade guard. It’s secured by two screws, one on each side of the saw.
3. Remove cap
Using your screwdriver, if necessary, unscrew both retaining screws.
4. Pry off housing cover
Once the screws are removed, you’ll be able to remove the cover by prying it off.

The brushes are housed in the brass part of the tool, which is held down by two screws on either side.
6. Unscrew housing retaining screws

7. Remove old brushes
Carefully remove old brushes from the housing, then discard them.
8. Position new brushes
Before positioning any new brush, make sure that the end of the wire lead is touching the brass part of the housing. For added security, use a flathead screwdriver to hold down the rear of each brush as you push it into place. Ensure that both brushes are securely in place before moving on.
9. Replace brush housing
Before replacing the brush housing, make sure that the gasket is seated correctly in its groove. You don’t want to have to go back in for this again! As you slide the housing back into place, you might notice that the tool becomes harder to push and pull this is normal, as new brushes take a little while to wear in.
