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
Parts of the hydraulic compactor, 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.
DANGER Explosion and fire
Explosions cause serious injury or death.
If the hydraulic compactor damages an underground
gas pipe, this may lead to an explosion.
►
Never operate the hydraulic compactor in the
direct vicinity of gas pipes.
►
Check gas line position plans of the complete
construction area.
NOTICE
Damage to underground cables or pipes
The hydraulic compactor can cause damage to
underground cables or water mains.
►
Obtain information on the locations of any
underground cables or mains.
♦
Before starting the hydraulic attachment, ensure
that
●
the hydraulic attachment and adapter plate do not
have any cracks,
●
and none of the hydraulic line connections leak.
