OPERATION
WARNING Components bursting
Components of the swivel joint may burst. Metal parts
may become projectiles and cause serious injuries
and damage property.
► Never operate the hydraulic breaker without
attached swivel joint covers.
WARNING Hot hydraulic oil squirting out
The hydraulic system is under high pressure. If
hydraulic connections come loose, hydraulic oil will
squirt out under high pressure. Hydraulic oil squirting
out can lead to serious injury.
► Immediately switch off the hydraulic attachment
and the carrier if you detect any leaks in the
hydraulic circuits.
► Depressurise the hydraulic system (see chapter
Depressurising the hydraulic system).
► Repair any leaks before operating the hydraulic
attachment again.
WARNING Hot parts
The breaker body, the working tool, hoses, pipes and
fittings become very hot during operation. Touching
them may lead to burns.
► Never touch hot parts.
► If you have to carry out activities where you have
to touch the parts, wait for them to cool down first.
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.
► Collect any hydraulic oil which escapes.
► Dispose of it in accordance with the applicable
environmental regulations.
NOTICE Hydraulic oil too hot
The temperature of the hydraulic oil must not exceed
80 °C. Higher temperatures will damage the seals
of the hydraulic breaker and the diaphragm of the
HP-accumulator.
► The temperature of the hydraulic oil must be
monitored.
► Shut off the carrier and the hydraulic breaker if
you measure an increased temperature in the tank.
► Check the hydraulic installation and the pressure
relief valve.
NOTICE Damage due to idling strokes
If the percussion piston carries out a hammer action
without hitting the working tool, it is carrying out an
idling stroke. If this happens it will lead to hydraulic
peak pressures which may damage the seals of the
hydraulic breaker and the carrier.
► Do not allow the percussion piston to carry out
idling strokes for a prolonged period of time.
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.
