Installing the New Switch

1. Re-install the wires

Push the wires back into the connectors--the tabs will lock them into place.

2. Connect the switch and field

You'll see some tabs on the switch. Insert them into the slots on the field to combine the two.

3. Install the armature

Slide the armature back into place through the switch and field assembly.

4. Place the armature and field assembly back in the housing

For this step, first grab the half of housing with the opening for the switch and the hole up front for the lock pin.

Now put the lock pin back into place near the tool's nose.

Add the the lock-pin spring.

Now install the motor and switch assembly. Take a moment to make sure the bearings line up with the notches.

5. Route the wires in the housing

You'll see some notches in the housing. Route the wires into these notches to prevent them from getting pinched later.

6. Re-install the other housing half

Now set the other half of the housing into place and secure it with the four screws.

7. Re-install the brushes

Now you can re-install the brushes. Just screw them back into each side of the housing.

8. Re-install the front cap

Screw the front cap back into place to finalize the repair.
