2.12 Electrical shock, precautions
DANGER Electrical shock
Any contact of the hydraulic attachment with electric cir-
cuits or other sources of electricity will lead to an electric
shock, resulting in serious injury or death. The hydraulic
attachment is not electrically insulated.
uNever work in the vicinity of electric circuits or other
sources of electricity.
uMake sure that there are no hidden circuits in the
work area.
uCheck wiring diagrams.
2.13 Falling stones, precautions
WARNING Fragments flying around
Fragments of material which come loose while operating
the hydraulic attachment may be flung away and can
cause serious injury if people are hit by them. Small ob-
jects falling from a great height can also cause serious
damage.
During hydraulic attachment operation the danger zone
is considerably greater than during the excavation oper-
ation due to fragments of stone and pieces of steel flying
around, and for this reason the danger zone must, de-
pending on the type of material to be worked on, be en-
larged correspondingly, or secured in a suitable manner
through corresponding measures.
uSecure the danger zone.
uStop the hydraulic attachment immediately if anyone
enters the danger zone.
uClose the windscreen and the side windows of the
driver's cab.
2.14 Emissions, precautions
WARNING Noise hazard
Operating the hydraulic attachment creates a loud noise.
Long term high sound pressure level can affect your
hearing.
uWear suitable hearing protection.
WARNING Lung disease
Dust may be generated when operating the hydraulic at-
tachment. If dust from rocks or silica dust, produced
when operating the hydraulic attachment on rocks, con-
crete, asphalt or other such materials, is inhaled this
may lead to silicosis (dust lungs, a severe lung disease).
Silicosis is a chronic disease which may lead cancer and
death.
uWear a suitable breathing mask.
2.15 Handling machines,
precautions
WARNING Narcotics, alcohol and drugs
Narcotics, alcohol and medicinal drugs make their users
less alert and affect their ability to concentrate. Negli-
gence and incorrectly assessing a situation can result in
serious injury or death.
uNever work on or with the hydraulic attachment when
under the influence of narcotics, alcohol or drugs
which affect your alertness.

Changes to the hydraulic attachment or the adapter
plate may lead to serious injury.
uNever carry out any changes to the hydraulic attach-
ment or the adapter plate.
uOnly use original parts or accessories approved by
Epiroc.
uModifications that entail new hazards may require a
new procedure for assessing conformity.
WARNING Changes to the HP-accumulator
Changes to the HP-accumulator may lead to serious in-
jury.
uNever carry out any changes to the HP-accumulator.
uAny modification will result in immediate invalidation
of the operating licence.
2.18 Environmental pollution,
precautions
NOTICE Environmental pollution due to hydraulic oil
Hydraulic oil is permanently environmentally harmful. Es-
caped hydraulic oil will lead to groundwater and soil con-
tamination. Organisms may die.
uCollect any hydraulic oil which escapes to avoid envi-
ronmental pollution. For minor volumes use an ab-
sorbing medium (in case of an emergency use soil).
In case of major leakages contain the hydraulic oil. It
must not drain off and penetrate the ground or enter
the water table or water supplies.
uCollect contaminated absorbing medium or soil in a
watertight box/container and close it tight.
uContact an authorized waste management company.
uDispose of all contaminated material in accordance
with the applicable environmental regulations.

3.2 Function
The operation of a hydraulic breaker is described in a
greatly simplified version below:
The pressure line »P« supplies oil at the operating pres-
sure of the carrier to the hydraulic breaker. The tank line
»T« returns the oil to the tank of the carrier. The HP-ac-
cumulator compensates pressure variations in the hy-
draulic system.
The percussion piston moves up and down in the cylin-
der. When the percussion piston is in its lower position, it
impacts the working tool. The percussion energy is
transferred to the material to be broken via the working
tool.
