Completing the Installation
Note: The 142-8633 Rocker Switch (8) and the 113-8491 Fuse (9) are required in order to provide power to the auxiliary electrical control circuit. You must install the switch and the fuse if these parts are not already installed on your machine as part of the installation of the work tool wiring group. The installation instructions for rocker switch (8) and fuse (9) are provided below.
Install the 142-8633 Rocker Switch (8) .
