operated from the cabin.
ØAvoid contact with holes and mounting surfaces
when mounting the breaker.
ØEnsure that when the excavator is in motion,
nobody is in the swing radius.
ØWear adequate personal protective equipment.

4. Installation
4.3 Setting the breaker
4.3.1 Set operating pressure
1) Stop the carrier engine.
2) Assemble the high pressure gauge to the high
pressure measuring port. Start the engine.
3) Set the tool of the breaker e.g. on a thick steel
plate or concrete.
4) Calibrate the excavator computer to produce the
correct ow and pressure.
5) Read the average pressure from the high pressure
gauge operating pressure.
6) Operating pressure is preadjusted at the factory
and there should be no reason to adjust it.
7) Stop the carrier and remove the gauge.
8) Tighten the plug of the pressure measuring point.
Relief valve
1) The relief valve is a safety device which is used to
protect the breaker when the pressure rises in the
hydraulic circuit.
2) The operating pressure of the breaker determines
the setting of the relief valve in the pressure line.
3) The relief valve setting should be acceptable as
per the specications of each model.
We advise that this work is to be undertaken by
a qualied technician from a Dehaco approved
dealership.

4.3.2 Setting of impact frequency
(from IBEX 1200GS)
To set the frequency (bpm), there is a standard
controller (set screw) installed in the IBEX hydraulic
breakers. As a result, the most efcient way of
breaking can be adjusted, depending on the working
conditions.
◊ This control is located on the right side of the
cylinder.
◊ Use a wrench and tighten the set screw to the end
for a minimum number of beats per minute.
◊ By loosening the screw, frequency will increase.
After setting, tighten the nut properly.

5. WORKING METHODS
WARNING!
ØEnsure the breaker is used only for suitable
applications.
ØInspect the area of the project prior to operating
the breaker.
ØPay particular attention to the safety of yourself
and others.
5.1 Correct working Methods
1) Prepare the excavator as for normal excavation
work. It is strongly advised that the front screen,
guard and door are closed to protect the operator.
- Move the excavator to the required position.
- Engage the parking brake if tted.
- Set drive to neutral .
- Disengage the boom lock if tted.
- It is also strongly advised to wear hearing
protection at this point. Anyone in the
surrounding area should also wear protection
to prevent hearing damage.
2) Adjust the excavator manually or using the on-
board computer to produce the correct ow and
pressure for the breaker.
3) Place the tool perpendicular to the material.
- Avoid small irregularities in the material that
will break easily causing idle strokes or an
incorrect working angle.
4) Use the excavators boom to press the breaker
rmly against the object. Ensuring that the tool
remains perpendicular to the material
- Never start the breaker until the correct force
has been applied to the tool.
5) Start the breaker.
- Stop the breaker immediately if someone
enters the working area. Whilst working, this
zone is much larger due to possible stone
fragments in the air. A reasonable perimeter
should be created during breaking.
6) Continuously feed the breaker.
- As the tool penetrates the material the
breaker must also be fed into the material.
Failing to do so will cause idle strokes and
increased wear upon the breaker.
- A continuous feed at the correct force will
increase the efciency of the breaker.
7) Ensure the breaker remains perpendicular in
relation to the material.
- If the material moves or its surfaces
breaks, the breaker should be repositioned
immediately. Failing to do so will cause
increased wear upon the breaker.
8) The breaker should not be worked continuously for
more than 15 seconds.

5. Working methods
5.1.1 Extra information for increasing efciency
The breaker should not be worked continuously for
more than 15 seconds. If more time is required for
a single break, attempt to break smaller sections
or change the angle of attack. It is generally more
effective to break smaller pieces than larger ones.
The breaker and its tool should never be used to pry
partially broken material apart. This will undoubtedly
cause the tool to break and cause accelerated wear
upon its bushes. This should never be attempted.
Although prying with the breaker is strongly forbidden
gently rocking the breaker during operation can
increase productivity. Whilst rocking the breaker,
air and dust that accumulates under the tool can be
released. This dust can inhibit the full impact energy
of the breaker.
This movement should be kept to a bare minimum.
Excessive movement can cause huge stresses on the
breaker and its tool. Just a few degrees of rotation (5°)
should create enough space to release this dust.
If an attempt is made to break a large section it is
possible the tool will be driven into the material
without any breaking effect. This can cause huge
spikes in the temperature of the chisel. Such high
temperatures can reduce the hardness of the tool
which will cause accelerated wear.
5.2 Operating Temperature
The operating temperature range of the IBEX breaker
is -20°C - 80°. When working outside of these
conditions special measures must be taken to ensure
the good working of the breaker.
5.2.1 Working in high ambient temperatures
The temperature of the hydraulic oil must be
continuously monitored. If the excavator cannot
maintain the temperature of the oil below 80 °C then
an oil cooler should be installed, or the excavator
should be inspected for the cause of the higher
temperatures. Using the correct oil is also essential.
Dependant on the climate and season the correct oil
and viscosity should be selected.
5.2.2 Working in low ambient temperatures
At low ambient temperatures the excavator and
attachment must be pre-heated prior to use.
In extreme conditions hot oil can cause catastrophic
damage to a cold breaker. This could cause damage to
the internal seals and cause the diaphragm to fail.
The hydraulic breaker will not perform optimally until
it and the oil has reached an optimal temperature.
Once a suitable temperature has been reached it will
be maintained during operation. Ensure that if the
breaker has stood still for a long period of time that
the temperature is checked before use.
5.3 Other important points
ØPay careful attention to the noise that the breaker
makes.
- If the sound becomes thinner and the impact
less efcient, the tool could be misaligned
and/or that there is not enough downward
force on the tool.
- The tool should be realigned and placed rmly
against the material.
ØAs a standard assembly the breaker must not be
used underwater. For underwater applications an
underwater kit must rst be installed to breaker
and excavator.
- Working underwater without this set can
cause catastrophic damage to the breaker.
- Contact Dehaco or an approved Dehaco dealer
for more information.
ØThe tool will remain very hot even after operation.
Ensure that great care is taken to avoid contact
with the tool whilst hot.

6. Maintenance
6.3 Hydraulic oil
ATTENTION!
ØWhen the breaker is used continuously, the
temperature of the hydraulic oil will normalize
at a certain level. At this temperature, the
viscosity of the hydraulic oil should be 20~40 cst
(2.90~5.35ºE)
ØThe breaker may not be started if the viscosity
of the hydraulic oil is above 1000 cst (131ºE) or
operated when the viscosity of the hydraulic oil
is below 15 cst (2.35ºE).
Problems when the hydraulic oil is too thick:
◊ Difcult start up.
◊ Stiff operation.
◊ Breaker strikes irregularly and slowly.
◊ Danger of cavitation in the pumps and hydraulic
breaker.
◊ Sticky valves.
◊ Filter bypass, impurities in the oil will not be
removed.
Problems when the hydraulic oil is too thin:
◊ Efciency losses (internal leaks).
◊ Damage to seals.
◊ Accelerated wearing of parts, because of
decreased lubrication efciency.
Special oils
◊ Is some cases special oils (e.g. biological oils and
non-inammable oil) can be used, please observe
following specications when considering the use
of special oil:
- The viscosity range in the special oil must
be in the given range of 15~1,000cSt
(2.35~131ºE).
Cleanliness of hydraulic oil
1) The hydraulic oil lter of the excavator will clean
the oil owing through the breaker.
2) The purpose of the oil lter is to remove impurities
from the hydraulic oil (air and water are also
impurities in oil).
3) Impurities also cause the oil to overheat and
deteriorate.
Oil lter
◊ The excavator oil lter must fulll the following
specications:
- The oil lter must be rated at a maximum of
25 micron.
- The oil lter must be a standard return line
lter rated to maximum working pressure.
- The oil lter must have a volume ow capacity
of at least twice the breaker’s maximum ow.
- The cooler must withstand a dynamic pressure
of 290 psi (20 bar).
- If the excavator’s oil cooler is too small either
the original cooler must be replaced with
a larger one or an auxiliary cooler must be
installed.
The auxiliary hydraulic cooler can be installed:
◊ In front of the radiator, in which case an additional
fan is not required, ie. maximum rise of the
cooling air is 5ºC (40ºF).
◊ Any other suitable place, using a fan either
hydraulically or electrically driven.
Damage caused by hydraulic oil contamination
1) The working life of the pumps is signicantly
shortened.
- Premature wear of parts.
- Cavitation.
2) Valves do not function properly.
- Spools bind.
- Premature wear of parts.
- Blocking of small holes.
3) Wear of cylinders and gaskets
4) Reduced breaker efcieny.
- Premature wear of moving parts and seals.
- Danger of the piston seizing.
- Oil overheats.
5) Shorten working life and reduced efciency of
hydraulic oil.
- Oil overheats.
- Oil quality deterioration.
- Electrochemical changes in hydraulic oil.
