Use the following instructions and the skidsteer examples on the following pages to set up your shear hydraulics properly.
1. Connect auxiliary hydraulic lines from the base machine to the hydraulic connections at the rotating head of
the shear. This circuit may have been installed from the factory or may require installation.
2. After connecting the auxiliary hydraulic circuit from the base machine to the shear, install an additional 1/4”
diameter case drain line.
3. Lift the boom and slowly engage the rotate function and open and close functions. Watch for hydraulic oil
leaks and interference.
4. Follow the hydraulic start-up procedure as described in this manual.
NOTICE
NOTICE
When installation is complete, slowly move the shear
through its full range of motion. Check for interference
between the shear and the base machine. Contact
dealer/factory immediately if any interference occurs
The same auxiliary control device will be used for the
open and close circuit and the rotate circuit. To operate the rotate function, the electrical switch will need
to be activated.
