DANGER! DO NOT open or attempt to repair the motor on your Tuthill pump. Return it to the place

DANGER! Disconnect all power prior to performing any service or maintenance. Failure to disconnect the
power may cause electrical shock, or unexpected starting of the motor, resulting in injury or death.
