OPERATION
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 hydraulic cylinder, 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 temperature will damage the seals of
the hydraulic parts.
►
Monitor the oil temperature.
►
Shut off the hydraulic attachment and the carrier
if you measure an increased temperature in the
tank.
►
Check the hydraulic installation and the pressure
relief valve.
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.
♦
Before starting the hydraulic demolition cutter,
ensure that
●
the hydraulic demolition cutter is complete,
●
the hydraulic demolition cutter and adapter plate
do not have any cracks,
●
the blade clearance is within tolerance
●
and none of the hydraulic line connections leak.
The preparations required prior to starting the
hydraulic demolition cutter 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 demolition cutter
must be between 0 °C and +80 °C during operation.
The full capacity of the hydraulic demolition cutter
can be achieved when the oil temperature is approx.
60 °C.
