2.8 Hydraulic installation,
precautions
WARNING Hydraulic pressure too high
If the hydraulic pressure is too high, the parts of the hy-
draulic attachment will be exposed to excessively high
loads. Parts can break loose or burst causing serious in-
juries.
uLay the drain line of the pressure relief valve directly
in the tank to ensure the safe functioning of the pres-
sure relief valve!
uThe pressure relief valve must be set at the maxi-
mum static pressure.
uThe pressure relief valve setting must be checked to
ensure that the maximum static pressure (see chap-
ter Technical specifications) of the hydraulic instal-
lation is not exceeded at any time. Attach a lead seal
to the pressure relief valve.
uPrior to their first use, the safety facilities on the hy-
draulic installation must be checked by a profes-
sional/authorised monitoring body for their quality
(CE mark etc.), suitability and proper functioning.
uIf any significant changes are made to the hydraulic
installation, a new acceptance inspection is to be
carried out in accordance with the relevant national
safety provisions.
WARNING Hot hydraulic oil squirting out
The hydraulic system is under high pressure. Hydraulic
lines may spring a leak or burst. Hydraulic oil squirting
out can lead to serious injury.
uWhen attaching the hydraulic attachment do not lay
any hydraulic lines through the carrier's cab.
uOnly use hydraulic lines which comply with the fol-
lowing quality requirements:
- For the function open and close
- Hydraulic hoses with 4 reinforcement steel wires
according to DINEN8564SH,
- Hydraulic pipes, seamless cold-drawn steel pipes
according to DINEN10305
- For the function turn
- Hydraulic hoses with 2 steel plaitings according to
DINEN8532SN,
- Hydraulic pipes, seamless cold-drawn steel pipes
according to DINEN10305.
2.9 Media/consumables,
precautions
WARNING Hot hydraulic oil under high pressure
Hydraulic oil will squirt out under high pressure if there is
a leakage. The jet of oil might penetrate people's skin
and cause permanent damage. Hot hydraulic oil can
cause burns.
uNever use your hands to find leaks.
uAlways keep your face away from a possible leak.
uIf hydraulic oil has penetrated your skin consult a
doctor immediately.
WARNING Hydraulic oil spills
Spilt hydraulic oil can make a floor slippery. If people slip
they can be injured. Hydraulic oil is environmentally
harmful and must not penetrate the ground or enter the
water table or water supplies.
uMake sure not to spill any hydraulic oil.
uImmediately clean the floor if you have spilt hydraulic
oil.
uObserve all safety and environmental protection pro-
visions when handling hydraulic oil.

precautions
DANGER Explosion and fire
Explosions cause serious injury or death. Explosives be-
ing cut by the hydraulic concrete buster may lead to an
explosion.
uNever operate the hydraulic concrete buster in the di-
rect vicinity of explosives.
uMake sure that no explosives are hidden in the con-
crete.
uCheck gas line position plans of the complete con-
struction area.
DANGER Explosion and fire
Operating the hydraulic concrete buster may create
sparks which ignite highly flammable gases. This may
lead to fire or an explosion.
uNever work in an environment with highly flammable
substances.
uMake sure that there are no hidden sources of gas in
the work area.
uCheck gas line position plans of the complete con-
struction area.
DANGER Explosion and fire
Dust-rich air can form an explosive atmosphere which
may ignite when operating the hydraulic concrete buster.
This may lead to fire or an explosion
uNever operate the hydraulic concrete buster in an ex-
plosion-hazard atmosphere.
uAlways provide sufficient ventilation when working in
buildings or in a confined area.
2.11 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.
2.12 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.

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.
2.14 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.

uModifications that entail new hazards may require a
new procedure for assessing conformity.
2.16 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.

The carrier driver operates the cutter valve, via a switch
on the floor or via a joystick in the carrier, for the function
»Open«. Oil is fed to the hydraulic cylinders via line »A«.
The piston rods retract. The cutter jaws open.
Turning
The carrier driver activates the carrier function »Turn«.
Oil is fed to the hydraulic motor. The hydraulic motor, lo-
cated in the upper part of the hydraulic concrete buster,
causes the lower part of the hydraulic concrete buster to
turn (cutter casing, cutter jaws, hydraulic cylinder). To
achieve endless turning of the lower part of the hydraulic
concrete buster, there is a rotary transmission between
the upper part and buster casing. The oil flows for the
functions »Open« and »Close« are transmitted through
the rotary transmission.

WARNING Hot hydraulic oil squirting out
The hydraulic system is under high pressure. If hydraulic
connections come loose or are disconnected, hydraulic
oil will squirt out under high pressure. Hydraulic oil
squirting out can lead to serious injury.
uDepressurise the hydraulic system before connecting
or disconnecting the hydraulic circuits of the hy-
draulic attachment (see chapter Depressurising the
hydraulic system).
NOTICE Environmental damage due to hydraulic oil
Hydraulic oil is environmentally harmful and must not
penetrate the ground or enter the water table or water
supplies.
uCollect any hydraulic oil which escapes.
uDispose of it in accordance with the applicable envi-
ronmental regulations.
NOTICE Damage to the hydraulic attachment
Working with a hydraulic attachment mounted to a long
reach boom may cause damage to the hydraulic attach-
ment.
uBefore working with a hydraulic attachment mounted
to a long reach boom consult the Epiroc Customer
Center / Dealer in your area.
5.1 Media/consumables
The following consumables are used when operating the
hydraulic attachment:
5.1.1 Mineral hydraulic oil
All hydraulic oil brands prescribed by the carrier manu-
facturer are also suitable for use when operating the hy-
draulic attachment.
However, the oil should comply with viscosity class
HLP32 or higher.
In summer and in hot climates, oils of viscosity class
HLP68 or higher should be used.
In all other respects the regulations of the carrier manu-
facturer are to be taken into consideration.
Optimum viscosity range =30 - 60cSt
Max. start viscosity =2000cSt
Max. oil temperature =80°C
Special conditions apply to using the hydraulic attach-
ment at low temperatures (see chapter Low ambient
temperature).
nCheck the oil filter!
An oil filter must be integrated in the tank line of the
hydraulic system. The maximum mesh width allowed
for the oil filter is 50microns; it must have a magnetic
separator.
5.1.2 Non-mineral hydraulic oil
NOTICE Mixed hydraulic oil
Never mix mineral and non-mineral hydraulic oils! Even
small traces of mineral oil mixed in with non-mineral oil
can result in damage to both the hydraulic attachment
and the carrier. Non-mineral oil loses its biodegradability.
uOnly use one type of hydraulic oil.
If you are using non-mineral oil it is imperative that the
name of the oil in use be indicated when returning the
hydraulic attachment for repair.
In order to protect the environment or on technical
grounds, hydraulic oils are currently being used which
are not classified as HLP mineral oils.
Before using hydraulic oils of this kind it is imperative to
ask the carrier manufacturer whether operations with
such fluids are possible.
Our hydraulic attachments are basically designed for use
with mineral oils. Consult the Epiroc Customer Center /
Dealer in your area before using other hydraulic oils ap-
proved by the carrier manufacturer. Following initial as-
sembly and after any workshop repairs, our hydraulic at-
tachments are subjected to a test run on a test bed pow-
ered by mineral oil.
5.1.3 Grease
nWhen handling oils and greases observe the safety
instructions that apply to these products.
