    • Preparation for Safe Operation
      • • The vibrating ripper should only be mounted on a carrier with sufficient load capacity.
      • • In case of using a quick coupler (hitch), determine the total weight including the quick coupler.
      • • Carriers below this weight class will not provide the required degree of stability and could even fall over during vibrating ripper use, causing personnel injury or machine damage. Carriers above this weight class may apply excessively high mecha…
      • • Make sure the vibrating ripper is compatible and match in capacity with carrier hydraulic systems.
      • • To protect the operator from injury due to flying rock splinters, the operator’s cab must be equipped with a protective shield or splinter guard. For information on the cab protector, consult carrier manufacturer or DEVELON Infracore dealer.
      • • Mounting the vibrating ripper requires the presence of an assistant, who must be instructed by the carrier driver. The carrier driver and assistant should agree beforehand on clear hand signals.
      • • To avoid equipment damage, follow the carrier maintenance schedule before operating the vibrating ripper.
      • • Check the vibrating ripper for wear, getting loose, breakage or crack. Do not operate in case any damages or failure is found.

    • Safety Information ON Safe Operating
      • • Always operate the vibrating ripper from the operator’s seat in the carrier cab, and also close the splinter guard on the driver’s cab during vibrating ripper operations.
      • • The vibrating ripper must not be used for disallowed applications. Refer to “Correct Working Methods” on page 5-3 of this manual for instructions on how to handle the vibrating ripper, and applications for which the vibrating ripper is unsuitable…
      • • Stop the operation if an abnormal noise or vibration is detected during the operation. Check the carrier and vibrating ripper.
      • • Never use the vibrating ripper in or underwater unless compressed air is supplied to the vibrating ripper. Refer to “Correct Working Methods” on page 5-3 for details.
    • Safety Information on Maintenance
      • • Pay careful attention to all relevant safety regulations. Most accidents occur when the instructions are not observed.
      • • Maintenance work must be performed with the carrier completely stopped, the stop valves shut off. The carrier must be on firm and flat ground with all the control levers switched off.
      • • Use only the lifting points provided and sufficiently strong lifting equipment when lifting the vibrating ripper.
      • • Do not start maintenance on the vibrating ripper until it has cooled because the vibrating ripper is heated up during operation. Some components, for example, tooth point, valve, piston or hydraulic connection parts become very hot.
      • • The hydraulic oil may be very hot and may cause severe scald. Before disconnecting hydraulic lines, bleed all hydraulic pressure in the lines. And, always relieve tank pressure of the carrier.
      • • Oil spouted out from the crack or small hole on hydraulic system can penetrate the skin and cause serious injury. Therefore, be sure that all the connections are tight and pipes and hoses are in good condition. Use a sheet of cardboard or wood to…
      • • Only the proper teeth must be used for maintenance. Use of improper teeth may cause personal injury, or damage to the vibrating ripper.
      • • Oily, greasy ground may be very slippery. Collect any oil and grease, and dispose it correctly for safety and environment.
      • • Keep personnel away from the vibrating ripper while servicing the tooth or hydraulic system.
      • • Unauthorized alteration on the vibrating ripper may cause the vibrating ripper serious troubles or reduce vibrating ripper life and performance. These cases cannot be guaranteed by DEVELON Infracore

      • • To avoid vibrating ripper damage, the hydraulic oil of the carrier must be kept clean. Check the contamination of the oil, then, if necessary, change the oil or flush the oil through a external filtration system, and replace the carrier oil filte…
      • • In case of using a newly installed one way piping, remove the contamination in the hydraulic line through bypass flushing (without connecting the vibrating ripper).
      • • Check the pressure setting of the relief valve on the vibrating ripper hydraulic line, this pressure-relief setting must be at least 30 ~ 40 bar higher than the measured maximum operating pressure of the vibrating ripper.
      • • The sealing faces and connecting threads of the hoses or fittings must be undamaged and free of sand or similar foreign particles.

  • Operating the Vibrating Ripper
    • • It must be used only for the usage designed by manufacturer
    • • The protection equipment like wire net must be placed into the operator cabin of the excavator so as to protect the operator from the broken pieces by breaking under operation.
    • • You must use only the hydraulic oil designated by the excavator and machine manufacturers. Only use hydraulic oils with sufficient viscosity.
    • • Stop to use the vibrating ripper when the hydraulic oil temperature reaches over 80 c-degree or below 0 c- degree.
    • • There is a risk of accident by the broken pieces by breaking under operation; the safe zone must be made more than the operation capacity of the excavator. If the person comes onto the zone, stop to operate the crushing immediately.
    • How to Operate Vibrating Ripper
      • • In case of ripping work, operator should work pushing the power of the arm and the bucket cylinder folding toward to the direction of (1) with moving boom cylinder up and down.
      • • In case of ripping with vibration, operator should make power to the bottom of tooth pulling the stone to the direction of (1).
      • • The relief pressure of the one way piping: must be measured with the stop valve shut off. And, it must be set to 30 ~ 40 bar higher than the measured maximum operating pressure of the vibrating ripper.
      • • Structure and working principle of Vibrating Ripper is extremely different with Breaker, never use same way of breaker such as continual hit with pressing the stone to vertical direction.
      • • Vibration speed must be within 1,400 rpm to 3,000 rpm. In case of speed slow down under 2,000 rpm or heavy pressure on vibrating ripper.
      • • Stop operation, move to find the crack of stone and start ripping operation.
      • • Do not make vibration over 10 sec in one point when the vibrating ripper can not make crack in the rock or the tooth of ripper does not penetrate to the rock.
    • Correct Working Methods
      • Never Push Vibrating Ripper
      • Never Turn the Carrier Using Ripper Tooth
      • Never use as lever to pull ripper tooth out.
      • Never Break Over 10 sec. on One Point
