6 Operation
WARNING Risk of explosion
If the hydraulic attachment is equipped with HATCON
explosion may occur when the contained lithium batter-
ies are penetrated by pieces of steel or reinforcing bars.
u Avoid impact of reinforcement, flying rocks or even
explosives on HATCON.
u Check the HATCON before operating.
!
NOTE: The hydraulic breaker or the
working tool is not to be used as a lift-
ing device. When lifting heavy compo-
nents use the hook on the carrier arm.
6.1 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.
6.2 Operating
6.2.1 Risk area
Before starting the hydraulic breaker, make sure that no
persons are in the risk area, 20meters (66ft) both hori-
zontally and vertically from the hydraulic breaker.
6.2.2 Breaking
CAUTION Machine and tool hazard
Continuous operation at full extension and/or retraction
can result in damage to the hydraulic cylinders.
u Always avoid operating the breaker with the cylinders
fully extended or retracted.
u Reposition the carrier and/or boom to avoid fully ex-
tended or retracted cylinders.
u Pay attention and look at what you are doing.
Never start the hydraulic breaker until both carrier and
the hydraulic breaker are in the correct position.
