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 re er to the chapter about vi-
brations, page 4.
•All HYCON breakers are supplied with sa ety trigger. The sa ety trigger may not
be dismounted. Always make sure that it is in order.
•In case o horizontal breaking or breaking above the head, always be aware o
material alling down.
•A ine jet o oil at pressure can penetrate the skin. It is there ore important never
to use your ingers to check or oil leaks and never to hold your ace close to su-
spected leaks – use a piece o cardboard instead. I oil has penetrated the skin,
you should get medical treatment immediately.
•Never leave the breaker when connected to the powerpack.
•Always use correct tool
•Be ore connecting the breaker to the power source, always check that the latch is
in order to prevent the tool rom alling out o the nose part.
•Always use approved hoses. Contact your dealer, i necessary. Mount the hoses
correctly – the valve housing is marked with ”P” and ”T”.
•The operator must make sure that there are no persons nearby when he starts
breaking. Flying pieces o broken material can cause severe injury.
•The operator must pay extra attention and show caution when working in di icult
working areas, such as slopes and other dangerous nature o the ground. Do not
reach too ar with the breaker, but always maintain a good ooting and keep your
balance.
•The operator must be properly trained in using the breaker or under supervision
o a quali ied 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 o the
breaker.

•Inspection or cleaning o the breaker, change o tool or disconnection o hoses
may never be done while the breaker is connected to the powerpack, as uninten-
tional activation o the breaker can cause severe damage.
•Always connect hoses to the breaker be ore starting the powerpack. Be sure that
all couplings are tight.
•The breaker may not be operated i 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 sa e and dry place.
•Try not to do a job with a breaker which is too small or the job.
•Keep the tool sharp or maximum breaker per ormance. 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 sur ace, as this may result in overload o 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 be ore connection.
•Always disconnect the hydraulic circuit be ore connecting or disconnecting the
breaker. I this is not done, there is a risk o damage to the quick release coup-
lings or the hydraulic system getting superheated.

Oil low and Pressure
Your new HYCON breaker is designed or a certain oil low, working pressure and
maximum pressure. A too high oil low and/or a too high pressure results in overload
o the breaker, meaning that the li etime o 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 low beyond its
design capacity, that the working pressure is correct and that the maximum allowed
pressure is not exceeded.
On page 6 you will ind a complete survey o the technical data, and on page 7 there
is a guide to connection to hydraulic power sources and how to ensure that the brea-
ker is not overloaded.
The HYCON breakers are available both as 20 l.p.m. and 30 l.p.m. models. The
individual types are stated on the ID-tag.
Vibration Level
There are many examinations about the risk o contracting the so-called “white in-
gers” disease as a consequence o the use o tools with high vibration level. Hand-
held electric, pneumatic and hydraulic breakers belong to this category.
To reduce the risk o injury, a number o guidelines or maximum daily use have
been laid down. The risk is minimized i you keep the times o maximum daily use.
It is there ore important to manu acturers o handheld breakers that they o er brea-
kers with a low vibration level.
At HYCON, we attach great importance to the protection o our customers in the
orm o a very low vibration level.
There ore, your new HYCON breaker is equipped with a handle designed or the
lowest possible vibration level, even though the breaker has high per ormance. On all
HYCON breakers we mount our best vibration-dampened handle as standard to pro-
tect you as user.
I you wish to obtain urther in ormation about the guidelines or maximum daily use,
please contact us.

Starting Instructions
START
•Insert tool
•Connect hoses – clean couplings be ore connection
•Set the power source on ”ON”
•Release the sa ety trigger
•Press the trigger lever down towards the handle
•Always work at right angles to the material, and only break pieces o a size
that makes the material break quickly. I it does not break quickly, either the
breaker is too small or the job, or you try to break too large pieces.
STOP
•Let go o the trigger lever
•The sa ety trigger automatically re-locks 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 o course HYCON powerpacks, the design o
which ensures your new HYCON breaker the absolute best working conditions.
It is important that the breaker is not subjected to an oil low and a working pressure
beyond its design capability. Please re er to the ID-tag on the breaker in case o
doubt.
Check the oil low and the working pressure by means o test equipment. The test
equipment should comprise a pressure gauge, a low meter and a valve or adjust-
ment o the pressure.
Make sure that:
•the oil low is not too high
•the working pressure is not too high
•the return pressure is not too high
•the pressure relie valve is not set higher than 160 bar
•the internal diameter o the hoses is su icient (min. ½”)
•all couplings are clean
•the power source is equipped with an oil ilter o min. 25 Micron
Hoses with too small internal diameter and/or de ect couplings cause the breaker to
work with incorrect working pressure.
Your dealer can help you check this.
I the output o the power source is too high:
•the power source must be adjusted to correct output
•or you can choose to mount a HYCON oil low divider to protect the breaker
against overload
•or you can choose one o our HYCON powerpacks. Your dealer can guide you
in choosing the right powerpack.
In case o doubt, please contact your dealer or HYCON A/S.

NB. At service/repair it is important to mount the hoses correctly. The eed line rom
the power source must be mounted at “P” and the return line at “T”. “P” and
“T” are marked on the valve housing.
Oil Types
The HYCON breakers use standard hydraulic oil, i.e. all types o mineral oil and
biodegradable oil, which comply with the ollowing values:
Recommended viscosity

-
40 cSt
Permitted viscosity
15
-
1000 cSt

I using biodegradable oil, we recommend the use o oil based on rape. Other types
o oil can be aggressive towards the seals. I you are in doubt, please ask your
dealer.
