Remove the metal brush clamp.

Remove the brush.

Locate Brush Pin & Motor Slot

Using your new brushes locate the brush pin and the motor slot.

Install New Brush.

Follow this step very carefully. If brush pin is inserted in the motor slot incorrectly, the brush will not cradle the armature correctly. The brush will raise up and the carbon will scratch the armature destroying your motor!

Slide the new brush in with the brush pin facing downward. The brush pin should be inside the motor slot.

The brush should lock into
place.

Replace Metal Brush Clamp & Tighten Screws

Replace metal brush clamp.

Replace and tighten both screws.

Be careful not to drop screws into the motor!

Be careful not to over tighten!

Re-plug Pink End.

Using a straight blade screwdriver, position it so that the brass terminal does not pop out when you push the pink end back onto the brush.

Gently push the pink end back on to the brass terminal.

The terminal should lock into place.

Test Run

Make sure to plug in your unit and test run the motor before replacing the lid.

The new brushes may spark more than normal until they wear in.

Turn it on and off a couple of times quickly to give the carbon a chance to cradle around the armature.

If you have a variable speed unit, turn it on low for a few minutes to give the carbon a chance to cradle around the armature.

Replace Foam

Gently replace foam to its original position.

Replace Lid & Screws

Replace the lid.

When starting each screw make sure you are screwing into the original holes.

If not, you could strip out each hole and your lid will not seal correctly.
