Installing and Removing the Attachment

Refer to the Operator’s Manual for the traction unit for the installation and removal procedure.

Important: Before installing the attachment, position the machine on a level surface, ensure that the mount plates are free of any dirt or debris, and ensure that the pins rotate freely. If the pins do not rotate freely, grease them.

Note: Always use the traction unit to lift and move the attachment.

Warning

If you do not fully seat the quick-attach pins through the attachment mount plate, the attachment could fall off the machine, crushing you or bystanders.

Ensure that the quick-attach pins are fully seated in the attachment mount plate.

Warning

Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury; otherwise, gangrene may result.

  • Ensure that all hydraulic-fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system.

  • Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.

  • Use cardboard or paper to find hydraulic leaks; never use your hands.

Caution

Hydraulic couplers, hydraulic lines/valves, and hydraulic fluid may be hot. If you contact hot components, you may be burned.

  • Wear gloves when disconnecting the hydraulic couplers.

  • Allow the machine to cool before touching hydraulic components.

  • Do not touch hydraulic fluid spills.

Testing the Breaker

Important: After installing the breaker on a machine, especially after storage, always test it before you break material to release air from the oil circuit. Using the breaker suddenly without releasing the air breaks the oil film and causes the breaker to seize.

  1. Park the machine on a level surface and engage the parking brake (if applicable).

  2. Raise the loader arms and tilt the breaker so that it is vertical. Ensure that the bit does not touch the ground.

    g359139

    Figure 13

  3. Slowly engage the forward hydraulics until the breaker piston rises, then slowly reverse the hydraulics before the piston impacts.

    Important: Do not allow the piston to impact.

  4. Refer to the table for testing times for the 2 stages.

    Important: Do not allow the piston to impact during the air removal and seal recovery time.

     12
     Air removal and seal recovery timePreparation time
    New breaker15 minutesOperate the machine for 10 minutes at 50% throttle then 20 minutes at 70% throttle
    After hoses are connected, no repairs
    After repairs to breaker20 minutes

Breaking Material

Important: Continuously impacting the same location for long periods of time creates high temperatures at the tip of the bit. This could cause the bit to lose its temper and mushroom under impact, destroying the bit.

  1. Adjust the throttle for your machine as appropriate for breaking material:

    • For 300-series machines, use full throttle (maximum engine speed), use low range (turtle position) on the speed-selector lever, and adjust the flow-divider valve to approximately the 10 o’clock position.

    • For e-Dingo machines, change the attachment mode to Hammer Mode.

    • For TX-series machines, use 3/4 throttle.

  2. Place the breaker bit within 15 to 46 cm (6 to 18 inches) from the edge of the material to be broken, at a 90-degree angle.

    g359138

    Figure 14

  3. Apply downward pressure with the loader arms until the front of the traction unit raises off the ground about 5 cm (2 inches).

    Note: Do not engage the breaker unless the bit is on the ground and downward pressure is applied.

    Important: Ensure that the hydraulic cylinders have at least 5 cm (2 inches) of stroke; do not use the concrete breaker with the hydraulic cylinders fully extended.

  4. Engage the breaker and maintain the downward pressure as the bit works its way into the material being broken.

  5. When the material is broken, immediately disengage the hydraulics to stop striking the material.

Breaking a Vertical Surface

  1. Position the bit on the vertical surface in the same manner as you would position it on a horizontal surface.

  2. Maintain pressure on the bit by driving the traction unit forward into the vertical surface while operating the breaker.

  3. Periodically lower the breaker to a vertical position to allow debris that may have collected in the breaker to fall out.

Transport Position

When transporting the attachment, keep it as close to the ground as possible, no more than 15 cm (6 inches) above the ground. Tilt it rearward.

g359749

Figure 15

  1. No more than 15 cm (6 inches) above the ground
  2. Tilt the attachment rearward.

Operating Tips

  • If the bit is positioned too far from the edge of the material, the material may absorb the energy and not break.

  • If the material does not break after 1 minute, stop the breaker and move the bit to a different location.

  • Do not bind the bit in the material being cut, otherwise the bit may bend or wear out prematurely. Ensure that all force applied to the breaker is inline with the bit, not side to side or front to back. This requires frequent adjustments in the positioning of the traction unit.

  • Listen to the sound of the breaker when is operating. The sound changes when downward pressure decreases. If the downward pressure from the unit is too weak, you will hear metallic strokes from the hammer as it incorrectly strikes the bit.

  • Excessive downward pressure produces strong vibrations in the unit.

  • Many materials do not break well with continuous hammering in one location. Each time that the breaker penetrates the material without breaking it, move it to a new location in a line parallel to the edge of the material, about 7.6 cm (3 inches) from the previous hole. This scores the material and, if done repeatedly, breaks off a large piece of the material.

    g359750

    Figure 16

  • If you are breaking rebar-reinforced concrete, use a chisel bit in the breaker to cut through the rebars in the concrete. You can also cut the rebar with a torch.

  • To improve the life of the breaker:

    • Ensure that the hydraulic cylinders have at least 5 cm (2 inches) of stroke; do not use the concrete breaker with the hydraulic cylinders fully extended.

    • Never pry with the bit of the breaker.

    • Avoid hitting material abruptly with the bit.

    • Do not use the breaker to lift or move material.

    • Do not operate the breaker under water; only allow the bit into water.

Maintenance

Caution

If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders.

Remove the key from the ignition before you do any maintenance.

Recommended Maintenance Schedule(s)

Before each use or daily
  • Grease the bit.(Grease every 3 hours of operation and after every washing.)
  • Check the hydraulic lines for leaks, loose fittings, kinked lines, loose mounting supports, wear, weather, and chemical deterioration.(Make necessary repairs before operating.)
  • Inspect and tighten all fasteners.
  • Inspect the mounting pins, holes, bit bushing, and retainer pins for looseness or wear. Reseat or replace as necessary.
    		•
    Every 40 hours
  • Measure the bit length when pressed into the bit holder.Replace the bit if the measured length is less than 200 mm (7.8 inches).
    		•
    Every 100 hours
  • Check the nitrogen charge in the accumulator.
    		•
    Before storage
  • Paint chipped surfaces.
    		•

    Greasing the Bit

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Grease the bit.(Grease every 3 hours of operation and after every washing.)
    		•

    Grease type: Chisel paste

    1. Park the machine on a level surface and engage the parking brake (if applicable).

    2. Tilt the breaker so that it is vertical and lower it to the ground to push the bit up into the breaker until it stops.

      Important: If you do not push the bit up into the breaker before greasing, grease may fill the space between the top of the bit and the breaker piston. This causes the piston to pressurize the grease and damage the seal when you next use the breaker.

    3. Shut off the engine and remove the key.

    4. Clean the grease fitting with a rag.

    5. Connect a grease gun to the fitting.

      g359783

    6. Pump grease into the fitting until either grease begins to ooze out of the lower bushing and retaining pin or pumping the grease gun becomes difficult.

    7. Wipe up any excess grease.

    Checking the Nitrogen Charge

    Maintenance Service IntervalMaintenance Procedure
    Every 100 hours
  • Check the nitrogen charge in the accumulator.
    		•

    Warning

    Within the breaker is a chamber containing pressurized nitrogen, which under the right circumstances could explode, injuring or killing you or bystanders.

    • Do not take apart the body of the breaker.

    • Do not attempt to charge the chamber yourself. Always take the breaker to an Authorized Service Dealer for charging.

    • Ensure that the breaker is charged only with nitrogen. Other gases can explode.

    • Do not ship the charged breaker via air freight.

    Inside the breaker is an accumulator, a chamber of pressurized nitrogen. After several hours of use the pressure may decrease, reducing the performance of the breaker.

    Strong vibrations in the auxiliary hydraulic hoses are a sign the pressure is dropping in the chamber. If this should happen, bring the breaker to your Authorized Service Dealer to be charged.

    Nitrogen gas pressure: 8 bar (116 psi)

    1. Park the machine on a level surface, engage the parking brake (if applicable), and lower the breaker on the ground.
