Original Instructions
6.2 Preparations before starting
WARNING Falling carrier
A carrier falling or tipping over due to the surface not be-
ing level may cause serious injury and material damage.
u Always observe great care when moving the carrier.
u Do not use the hydraulic attachment until the carrier
is positioned stably.
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.
u Secure the danger zone.
u Stop the hydraulic attachment immediately if anyone
enters the danger zone.
u Close the windscreen and the side windows of the
driver's cab.
The preparations required prior to starting the hydraulic
attachment depend on the ambient temperature:
• Ambient temperature below 0°C(32°F) (see chap-
ter Low ambient temperature).
• Ambient temperature above 30°C(86°F) (see
chapter High ambient temperature).
The oil temperature in the hydraulic attachment must be
between 0°C(32°F) and +80°C(176°F) when operat-
ing the breaker.
The full capacity of the hydraulic attachment can be
achieved when the oil temperature is approx.
60°C(140°F).
n
Make sure that there are no people in the danger
zone.
n
Start the carrier as instructed by the carrier manufac-
turer.
n
Let the carrier heat up until the operating temperature
prescribed by the carrier manufacturer has been
reached.
n
Put the carrier in its working position.
n
Put the working tool on the material to be broken.
6.3 Switching the hydraulic
breaker on and off
After properly attaching the hydraulic attachment to the
carrier, the hydraulic attachment can be operated using
the carrier‘s hydraulic system. All functions for normal
carrier operation remain intact.
The hydraulic attachment is switched on and off using
electrical and hydraulic signals.
If you have any questions about electric / hydraulic com-
mands, consult the carrier manufacturer and / or the
Epiroc Customer Center / Dealer in your area.
n
Switch the hydraulic attachment on and off, as de-
scribed in the carrier‘s operating instructions.
n
When leaving the driver’s cab, set the safety switch/
lever for the electrical / hydraulic attachment installa-
tion to the „OFF“ position.
Carry out the above actions to prevent any unintended
start-up of the hydraulic attachment.
6.4 Functional test
Always carry out a functional test before putting the hy-
draulic attachment into use to check that all hydraulic
lines and connections are tight and that the hydraulic at-
tachment works without any problems.
n
Prepare the hydraulic attachment so that you can
start using it.
n
Carry out a couple of test impacts on the material to
be broken.
n
Check the hydraulic lines and make sure that the hy-
draulic attachment works without any problems.
n
Immediately switch off the hydraulic attachment if oil
escapes from the hydraulic lines or if other defects in
functioning occur.
n
Depressurise the hydraulic system (see chapter De-
pressurising the hydraulic system).
n
Only use the hydraulic attachment again after having
repaired all leaks and operating defects.
