Before the first installation
:
Before mounting
/
dismounting the hydraulic tool
and
/
or any maintenance work on the hydraulics of
the hydraulic tool
/
carrier the hydraulic system must
be depressurized!
When using or transporting the carrier with the hy
draulic breakers attached, the instructions included in
the operating manual supplied by the carrier manu
facturer must also be obser
v
ed.
Do not run any hydraulic lines for attachment of the hy
draulic breaker through the dri
v
er’s cab! Hydraulic lines
may spring a leak or e
v
en burst! During operations, the
hydraulic oil becomes
v
ery hot.
Mounting the hydraulic breaker:
M
ounting the hydraulic breaker re
q
uires the pres
ence of an assistant, who must be instructed by the
carrier dri
v
er. The carrier dri
v
er and assistant should
agree beforehand on clear hand signals.
For transport purposes, use only the lugs pro
v
ided
and hoisting e
q
uipment of sufficient capacity.
The hydraulic breaker should only be mounted on an
e
x
ca
v
ator with sufficient load capacity. The carriers
specified under
S
3
, Technical specifications
are needed to install the hydraulic breaker.
Carriers below this weight class will not pro
v
ide the
re
q
uired degree of stability and could e
v
en fall o
v
er
during hydraulic breaker use, causing injury and
damage.
Carriers abo
v
e this weight class may apply e
x
cess
i
v
ely high mechanical loads to the attachment.
When attaching the adapter use only the special
steel screws included in supply.
Check the nominal width of the hydraulic lines on
e
x
isting hydraulic systems.
I
t is important that supply
and return lines for the hydraulic oil are ade
q
uately
dimensioned.
Keep your hands away from bores and fitting sur
faces when mounting the hydraulic breaker, es
pecially when the carrier boom is mo
v
ing.
Collect any oil which runs out and dispose of it in ac
cordance with the applicable statutory pro
v
isions to
a
v
oid en
v
ironmental hazards.
When putting into use hydraulic breakers with
high−pressure
accumulators
the
applicable
national requirements are to be observed, e.g. in
Germany an authorized person/inspection body is
to inspect and certify the system on site before put
ting it into use.
Fitting and removing the working tool:
Always wear protecti
v
e glasses when fitting or re
mo
v
ing the working tool, since metal splinters may fly
off when hammering out the locking bolts.
The working tool should only be fitted in the way de
scribed in this operating manual.
Ne
v
er use your fingers to check whether the re
cesses on the working tool shaft are aligned to the
slots for the retainer bars.
Operating the hydraulic breaker:
Close the front screen
/
splinter guard on the dri
v
er’s
cab to protect the dri
v
er from flying rock splinters
during breaker operations.
Wear ear protectors
The national regulations of the country of use as re
gards e

ator operations with percussi
v
e tools
shall apply.

Do not start up the hydraulic breaker until both carrier
and hydraulic breaker are in the correct position.
S
top the hydraulic breaker immediately as soon as
persons are in the danger zone. The danger zone
during the breaker operation is considerably greater
than during the e
x
ca
v
ation operation
−
on account of
fractions of stones and pieces of steel flying around
−
and for this reason, the danger zone must, depend
ing on the type of material to be worked on, be en
larged correspondingly, or the danger zone must be
secured in a suitable manner through corresponding
measures.
Do not touch any hot parts
The hydraulic breaker heats up during operation.
Monitor the oil temperature
The temperature of the hydraulic oil must ne
v
er e
x
ceed
8
0°C.
I
f higher temperatures are measured in
the tank, the hydraulic system and
/
or the pressure
