Broken or leaky hydraulic hoses pose a hazard.

Use extra caution when handing all hydraulic connections. Make sure that the machine’s engine is

stopped and that there is no hydraulic pressure within the system.

: Prolonged contact with hydraulic oil

Prolonged or repeated skin contact with any kind of hydraulic oil leads to loss of fat content in the

skin. That can lead to dryness, irritation or skin inammations. Hydraulic oil also contains dangerous

substances that can cause skin cancer. If the basic safety and hygiene standards are observed during

work, handling hydraulic oil should not cause health problems.

: Hot surfaces and hot hydraulic oil

Be aware that the hydraulic circuit can get very hot.

After working, some of the Crusher’s components get very hot. There is a risk of minor burns.

: Risk of hearing loss

It is mandatory to wear ear protection.

: Crushing hazard

Be especially cautious when installing, removing and handling the Crusher, to prevent it from tipping or

falling over.

Not following the instructions can result in an increased risk of trapment.

INSTRUCTIONS MANUAL

TOP BRACKET DIMENSIONS

When installing an Xcentric Crusher on a base machine such as a hydraulic excavator, backhoe loader, etc.

a top bracket will be required to connect the Crusher to the base machine. This can be ordered from Xcentric

Ripper International/Grado Cero Sistemas S.L.U. at the time the Xcentric Crusher is ordered. Details of the type

and model of the base machine will be required and if the base machine is equipped with a quick coupler,

details of the manufacturer and model number will also be required.

If a top bracket is not ordered or if the Xcentric Crusher is to be mounted on a different base machine than the

previous installation, a top bracket will have to be ordered separately from Xcentric Ripper International/Grado

Cero Sistemas S.L.U. or manufactured locally.

IMPORTANT!

When manufacturing a top bracket to mount an Xcentric Crusher on an excavator it is very important to

follow the guidelines listed below:

1. Cut the plates for the top bracket to the dimensions given in the following drawings.

2. Weld on to the top plate the mounting ears required to mount the Xcentric Crusher on the specic

excavator to be used for this Crusher.

3. After the above operations have been carried out the surface of the top bracket plates which will

be in contact with the Xcentric Crusher must be milled perfectly at across the whole of both of the

surfaces.

4. Drill the required mounting bolt holes to the dimensions given in the drawings. They must be

drilled and use at least the indicated ones for each model.

It is not allowed to use a top bracket where the mounting surfaces have not been milled perfectly at.

INSTRUCTIONS MANUAL

INSTALLING AND REMOVING THE CRUSHER

INSTALLATION

• The operations of assembly and disassembly of the Xcentric Crusher on the base machine should be

performed by qualied and prepared for it personnel.

• Only qualied staff who has read carefully the instructions for assembly and disassembly of the

Xcentricr Crusher on the base machine, as described in the instruction manual, can perform these

operations.

• User companies will prepare specic safe work instructions to be observed by its staff.

• The operator of the machine will be personnel who have received proper training and have

demonstrated competence.

• Refer to the excavator manual to locate the valves of control at the end of the pressure line and return

line on the arm of the base machine.

• Access to the machine will be restricted to authorized personnel while bringing out the assembly,

installation and commissioning.

• Personnel in charge of the movements will control that nobody will be affected by the moving element.

: Installation on the excavator

Check to see that the top bracket and the excavator arm t together. Position the Crusher according to the

illustration.

Install the Crusher only on an even surface with the elements to be connected standing across from each

other.

Additional adapters or mounting brackets must not be welded to the Crusher. This will void both the

warranty and the EC declaration of conformity.

: Hydraulic circuit adjustment and hose connections

Before installing the hoses between the Crusher and the excavator the hydraulic circuit pressures and ow

must be set as follows:

1. Install pressure gauges at the end of the pressure and return lines on the excavator arm.

2. Make sure that the excavator circuit is in the “double effect” position (shear or cramp).

XCENTRIC CRUSHER

WARNING!

The above relief valve pressure settings must never be exceeded. Operating a Crusher with excessive

pressure can possibly lead to serious damage to the hydraulic motor and control valve block cartridge

elements.

CAUTION!

The hydraulic hoses are not delivered with the Crusher. Do not use hydraulic quick-connect couplings

on the hoses as these can reduce the Crusher’s performance and damage the hydraulic motor. Make

sure that the bends in the hydraulic hoses in all positions exceed the minimum radius specied by the

manufacturer and that the hoses have no contact with other components.

6. Stop the engine. Remove the plugs (or caps) from the shut-off valves and install a ow meter. Open the

shut-off valves.

7. With he excavator at working regime, ensure that the maximum ow never exceeds these values:

XC 15 - 100-120 l/min / XC 17 - 140-160 l/min / XC 20 - 160-180 l/min

to 4MPa to 4MPa to 4MPa

XC 30 - 180-200 l/min / XC 40 - 300 l/min / XC 50 - 340 l/min / XC 60 - 500 l/min

to 4MPa to 4MPa to 4MPa to 4MPa

8. After ensuring the oil ow is correct, stop the engine, close the shut-off valves and remove the ow meter

and hoses.

9. A total of three hoses must be connected from the Crusher to the excavator. The rst two hoses, pressure

and return, must be designed for a continuous pressure of at least 300 bars and withstand additional

pressure peaks. We recommend the use of a 4SH hose for the pressure hoses, and a 2 wire hose for the

drain hose. The connections to the Crusher must be of the type SAE 6000 1” for the pressure and return;

SAE 6000 ½” for the drenage. It is mandatory the hoses to be sealed with appropriate accessories when

the Crusher is not operating.

10. Connect the hydraulic hoses between the excavator and the Crusher. The hydraulic hoses are

connected as follows:

• Remove the plugs.

• Before connecting the hoses, make sure that the connections and hoses are clean.

• Connect Crusher hoses to the shutoff valves on the arm of the excavator.

• Connect the XC drain hose to the drain line of the excavator.

3. Ensure that the shut-off valves at the end of the pressure and return lines on the excavator arm are in the

closed position, to prevent hydraulic ow from reaching the Xcentric Crusher.

4. Start the engine and raise the hydraulic oil temperature to a minimum of 40ºC.

5. Operate the Crusher control valve with the engine running at full r.p.m. and read the pressure on the

gauge on both lines. This pressure is the excavator circuit relief valve setting and should be set at the

pressure for your specic model of Crusher as listed in the following table:

INSTRUCTIONS MANUAL

CAUTION!

To avoid or reduce damage to the hydraulic motor or its seals, it is mandatory to always install the case

drain line from the case drain line connection on the Crusher directly to the hydraulic tank or lter just

before the hydraulic tank. Under no circumstances is the drain line of the Crusher to be connected to

other case drain lines on the excavator as this can lead to excessive back pressure in the Crusher case

drain line.

11. Install a pressure gauge in the case drain line.

12. Open the oil shut-off keys on the excavator towards the bucket. Start with the return line (normally on

the right side of the excavator arm but this can differ depending on the excavator’s manufacturer, so

check which side is the return side before opening) and then open the pressure line.

13. Start the excavator engine.

14. Lift the Crusher off the ground, idle or run the engine at a low RPM and press the Crusher’s pedal for

about 2 minutes to let the air out of the hydraulic system and at the same time check the system for

leaks. If leaks occur, seal them right away.

15. Check the drain line pressure. This pressure should never exceed 0.4 MPa (4 bar) in any case.

16. Stop operating the Crusher.

17. Again check the drain line pressure. This should be at zero. If there is a pressure this is caused by

pressure coming back from the excavator circuit. The cause of this has to be found and rectied (check

to see if the bucket’s drain line is connected to other drain lines from elements on the excavator such

as the swing motor or travel motors, if so the bucket’s drain line must be connected directly to the tank

or lter just before the tank).

18. If the bucket’s drain pressure is correct lift the Crusher up and set it in the rest position. Then stop the

engine.

19. Remove the pressure gauges tted in the pressure, return and bucket’s drain lines.

: Excavator hydraulics

Check to make sure that the quality of the hydraulic oil and the excavator’s lter comply with the manufacturer’s

specied requirements. (ISO 4406 purity class 20/18/13).

: Start-up and rst use

Start-up and rst operation of the Crusher are always performed by a technician authorized by Xcentric Ripper

International/Grado Cero Sistemas, S.L.U.

After all of the previously described tasks have been performed, the Crusher is put into operation as follows:

• Before starting work, you should leave the engine running for a few minutes. If you are going to work

in cold climates, it is advisable to leave the Crusher running until a temperature of approximately 40°

C (104° F) is reached.

• When the machine is ready, start lling the bucket. After lling the bucket, turn the Crusher to reach

the best position to help extraction. Then activate the mechanism slowly and gradually until the

maximum number of revolutions are reached.

• When nished shredding the material, repeat the above operation.

INSTRUCTIONS FOR USING THE XCENTRIC CRUSHER

Even though the Crusher requires no daily maintenance, for a long lasting life it must be kept clean and shock

free Before starting work with the Crusher, a daily visual inspection must be made.

PRECAUTIONS WHEN OPERATING THE CRUSHER

The Xcentric Crusher is intended for crushing and demolition materials reduction, so it is possible that a small

part of the material to crush is projected during use. It is therefore advisable to respect the safety distance.

Pay attention to the material to be crushed, large portions are not recommended, as they could get stuck in

the mouth of the bucket.

The operator in charge of the base machine will control that nobody can be affected by the movements of the

Xcentric Crusher.

Only qualied staff who has carefully read the instructions for use of Xcentricr Crusher described in the

instruction manual can perform such operations.

User companies will prepare specic safe work instructions to be observed by its staff.

User companies, will instruct and observe all mandatory regulations of law enforcement and those relevant to

the prevention of occupational risks and environmental protection.

The operator of the machine will be personnel who have received proper training and have demonstrated

competence.

The operator of the main operating machine will always remain inside the cab while the Xcentric Crusher is

working and being handled by the operator.

HANDLING THE XCENTRIC CRUSHER

The best way to learn to handle the Crusher is to operate it, although the use of it doesn’t differ much from a

normal crusher, therefore its handling is simple.

The way to use it is as follows:

• Fill the Xcentric Crusher with the material to be

ground.

• Rotate the bucket so that the opening of the material

outlet is at the bottom.

• Operate the Xcentric Crusher.

• Once you have completely crushed the material

deposited in the bucket, repeat the operation.

• The Xcentric Crusher should always run with the

crusher bucket upright.

• In the event that the Xcentric Crusher can not begin

to process the material in an upright position, the

amount of charge to be processed must be reduced.

INSTRUCTIONS MANUAL

WHAT TO DO IN CASE OF BLOCKED MATERIAL?

In the case the Crusher is blocked, it is strictly forbidden to remove the obstacle manually.

To unlock the jaws:

• Stop the Xcentric Crusher.

• Change the direction of movement of the jaws.

• If the jaws are still blocked, place the bucket with the loading mouth looking down and operate the

bucket in both directions until it is released.

• If necessary, lightly shake the Crusher.

NOTE

In no case hit the Xcentric Crusher against the ground or any other element in order to unlock it.

ATTENTION!

In case you have to gure out the cause of the machine blockage, it is strictly forbidden to hit the bucket

on the oor or against things horizontally. In case of damage caused by this operation the manufacturer

is exempt from any liability.

The XC has two rotation directions, one

for working and one for unlocking. In the

working direction, the jaw pushes the

material towards the outlet. In the sense of

release, the jaw pushes the material into

the inlet making it easier the unlocking

operation.
