S3015, S3025 and S3035 Demolition and Scrap Shears Caterpillar


Hydraulic System Air - Purge

Usage:

S3015 LNP

  • Check the oil level in the host machine.

  • Clean all the hydraulic fittings before installing the hydraulic fittings. Inspect all the hydraulic fittings. Repair any damaged fittings. Replace any worn fittings. Connect all the hydraulic hoses. Remove the rotation lock.

  • Start the engine of the host machine. Slowly cycle the hydraulic controls. Do not fully open the jaw, fully close the jaw, or attempt to process material before purging air from the shear cylinder. Check for any hydraulic leaks. Repair any hydraulic leaks.

  • Raise the shear away from the ground. Slowly move the shear through the full range of motion to check for interference with the hoses, brackets, or machine.

    Note: The work tool must move freely from the host machine. The auxiliary hoses should not get pinched or jammed when the machine moves or the shear is moved.

  • Position the shear vertically with the jaw facing the ground.

  • Slowly extend the cylinder (close the jaw) to the full extend position. Do not apply full operating pressure. Slowly retract the cylinder (open the jaw) to the full retract position. Do not apply full operating pressure. Repeat this procedure 5 more times.

  • Slowly extend the cylinder to the full extend position reaching full operating pressure. Slowly retract the cylinder to the full retract position reaching full operating pressure. Repeat this procedure 2 more times.

  • After the cylinder has been purged of air, fully retract the cylinder (open the jaw). Turn Off the machine, check for leaks, repair any leaks, and check the excavator hydraulic fluid and ensure it is filled to the proper level.

  • Refer to Testing and Adjusting of the host machine for further Information.
