Note: Ensure that the shear is compatible with the host machine. Ensure that the mounting bracket is compatible with the host machine and the shear. Consult your Verachtert dealer for information on matching the shear to the host machine.Note: It is possible to mount the shear to the stick of the host machine or to the boom of the host machine. There are auxiliary lines kits that are available for the hydraulic system. Become familiar with the controls of your machine. Become familiar with the configuration of your machine.Note: If the host machine is equipped with a Quick Coupler, consult the operating manuals for the Quick Coupler before you attempt to mount the shear.
Clean all of the pins. Grease all of the pins.
