Safety Precautions
•Only use the breaker in accordance with the local working regulations on allowed
working time based on breaker vibration level. Working with the breaker longer
than prescribed may damage the operator. Please refer to the chapter about vi-
brations page 4.
•In case of horizontal breaking or breaking above the head always be aware of
material falling down.
•A fine jet of oil at pressure can penetrate the skin. It is therefore important never
to use your fingers to check for oil leaks and never to hold your face close to su-
spected leaks – use a piece of cardboard instead. If oil has penetrated the skin
you should get medical treatment immediately.
•Never leave the breaker when connected to the powerpack.
•Always use correct tool
•Always use approved hoses. Contact your dealer if necessary. Mount the hoses
correctly – ”P” and ”T” are marked on the breaker.
•The operator must make sure that there are no persons nearby when he starts
breaking. Flying pieces of broken material can cause severe injury.
•The operator must pay extra attention and show caution when working in difficult
working areas such as slopes and other dangerous nature of the ground. Do not
reach too far with the breaker but always maintain a good footing and keep your
balance.
•The operator must be properly trained in using the breaker or under supervision
of a qualified instructor.
•The operator must always use protective goggles earplugs hard hat and shoes
when operating the breaker.
•Never use the breaker close to electric cables. Prior to operation check whether
there are hidden or buried cables in the ground.
•Never wear loose clothing as it may get entangled in the moving parts of the
breaker.

•Inspection or cleaning of the breaker change of tool or disconnection of hoses
may never be done while the breaker is connected to the powerpack as uninten-
tional activation of the breaker can cause severe damage.
•Always connect hoses to the breaker before starting the powerpack. Be sure that
all couplings are tight.
•The breaker may not be operated if the oil temperature is above 70 C°. Operation
at higher temperatures may result in the breaker getting warmer than normal and
the operator risks getting burnt on it.
•To avoid all personal injury and damage to material all repair maintenance and
service work must be carried out by authorized or properly trained persons only.
•A breaker not in use should always be kept in a safe and dry place.
•Try not to do a job with a breaker which is too small for the job.
•Keep the tool sharp for maximum breaker performance. Make sure that the tool is
sharp-pointed and not round.
•The breaker may never be operated without tool or without being held against
the working surface as this may result in overload of the breaker.
•Always make sure that the breaker labels and warning signs are legible.
•Always use hoses couplings and spares as such recommend by HYCON A/S.
•Repairs may only be carried out by experienced personnel.
•Make sure that all couplings are cleaned before connection.
•Always disconnect the hydraulic circuit before connecting or disconnecting the
breaker. If this is not done there is a risk of damage to the quick release coup-
lings or the hydraulic system getting superheated.

Oil Flow and Pressure
Your new HYCON breaker is designed for a certain oil flow working pressure and
maximum pressure. A too high oil flow and/or a too high pressure results in overload
of the breaker meaning that the lifetime of your new HYCON breaker will not be as
expected and that your service and repair costs will be too high.
It is important to check that the breaker is not supplied with an oil flow beyond its
design capacity that the working pressure is correct and that the maximum allowed
pressure is not exceeded.
On page 6 you will find a complete survey of the technical data and on page 9 there
is a guide to connection to hydraulic power sources and how to ensure that the brea-
ker is not overloaded.
Vibration Level
There are many examinations about the risk of contracting the so-called “white fin-
gers” disease as a consequence of the use of tools with high vibration level. Hand-
held electric pneumatic and hydraulic breakers belong to this category.
To reduce the risk of injury a number of guidelines for maximum daily use have
been laid down. The risk is minimized if you keep the times of maximum daily use.
It is therefore important to manufacturers of handheld breakers that they offer brea-
kers with a low vibration level.
At HYCON we attach great importance to the protection of our customers in the
form of a very low vibration level.
Therefore your new HYCON breaker is designed in a way that gives a low vibration
level even though the performance is high.
If you wish to obtain further information about the guidelines for maximum daily use
please contact us.

Startin Instructions
START
•Insert tool
•Connect hoses – clean couplings before connection
•Set the power source on ”ON”
•Press the trigger lever down towards the handle
•Always work at right angles to the material and only break pieces of a size
that makes the material break quickly. If it does not break quickly either the
breaker is too small for the job or you try to break too large pieces.
STOP
•Let go of the trigger lever

Connection to Hydraulic Power Sources
The breaker can be connected to various hydraulic power sources such as excava-
tors trucks loaders tractors etc. and of course HYCON powerpacks the design of
which ensures your new HYCON breaker the absolute best working conditions.
It is important that the breaker is not subjected to an oil supply and a working pres-
sure beyond its design capability. Please refer to the ID-tag on the breaker in case of
doubt.
Check the oil supply and the working pressure by means of test equipment. The test
equipment should comprise a pressure gauge a flow meter and a valve for adjust-
ment of the flow.
Make sure that:
•the oil flow is not too high
•the working pressure is not too high
•the return pressure is not too high
•the pressure relief valve is not set higher than 160 bar
•the internal diameter of the hoses is sufficient (min. ½”)
•all couplings are clean
•the power source is equipped with an oil filter of min. 25 Micron
Hoses with too small internal diameter and/or defect couplings cause the breaker to
work with incorrect working pressure.
Your dealer can help you check this.
If the output of the power source is too high:
•the power source must be adjusted to correct output
•or you can choose to mount a HYCON oil flow divider to protect the breaker
against overload
•or you can choose one of our HYCON powerpacks. Your dealer can guide you
in choosing the right powerpack.
In case of doubt please contact your dealer or HYCON A/S.
