actuator tabs are even to within 1/16 inch. If
required, bend the lower tab up to match the
higher tab.

switches back until they both click, tighten
the switches in this position.

These brushes wear quicker as the length shortens
due to increased heat. Spring inside brush housing
will damage motor if brushes are allowed to wear
away completely.
Periodically check the length of the carbon brushes.
Replace both carbon brushes when either is less than
3/8" (9.5mm) long.
