Loosen Brush Screws

Loosen the two screws holding the metal brush housing enough to allow the brush to lift upward and slide out.

NOTE: It is not necessary to completely remove the screws!

Remove Brush

Gently lift the metal brush upward and pull it out.

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.

Tighten Screws

Tighten both screws.

Be careful not to over tighten!

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.

Seal Unit With Silicone Caulking

Note: If your unit is a TOTE, MODEL 1 or MODEL 1A, you do not need to reseal the lid. Skip steps 11, 13 & 14.

Remove old excess silicone caulking from lid and unit with a utility knife.

Seal all around the top of the unit with new silicone.

Replace Lid & Screws

Replace the lid. Silicone may squeeze out, this is normal.

Start each screw, do not tighten until all screws are started. If not, you will not be able to get the last couple of screws in.

Let Silicone Dry

It is important that you allow your unit to sit overnight so that the silicone can dry. If silicone is not allowed to dry properly, the lid  may leak.

Cut Away Excess Silicone

Using your utility knife cut away the excess silicone.
