Preparations before starting
WARNING Falling carrier
A carrier falling or tipping over due to the surface
not being level may cause serious injury and
material damage.
►
Always observe great care when moving the
carrier.
►
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 objects falling from a great height
can also cause serious damage.
During hydraulic attachment operation the danger
zone is considerably greater than during the
excavation operation due to fragments of stone
and pieces of steel flying around, and for this
reason the danger zone must, depending on the
type of material to be worked on, be enlarged
correspondingly, or secured in a suitable manner
through corresponding measures.
►
Secure the danger zone.
►
Stop the hydraulic attachment immediately if
anyone enters the danger zone.
►
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
(see chapter Low ambient temperature).
•
Ambient temperature above 30 °C
(see chapter High ambient temperature).
The oil temperature in the hydraulic attachment
must be between 0 °C and +80 °C when operating
the breaker.
The full capacity of the hydraulic attachment can
be achieved when the oil temperature is approx.
60 °C.
◆
Make sure that there are no people in the
danger zone.
◆
Start the carrier as instructed by the carrier
manufacturer.
◆
Let the carrier heat up until the operating
temperature prescribed by the carrier
manufacturer has been reached.
◆
Put the carrier in its working position.
◆
Put the working tool on the material to be
broken.
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
commands, consult the carrier manufacturer and/or
the Atlas Copco Customer Center/Dealer in your
area.
◆
Switch the hydraulic attachment on and off, as
described in the carrier‘s operating instructions.
◆
When leaving the driver’s cab, set the safety
switch/lever for the electrical/hydraulic
attachment installation to the „OFF“ position.
Carry out the above actions to prevent any
unintended start-up of the hydraulic attachment.
