6 Operation
WARNING
Hot hydraulic oil squirting out
The hydraulic system is under high pressure. If hydraulic
connections come loose, hydraulic oil will squirt out un-
der high pressure. Hydraulic oil squirting out can lead to
serious injury.
u
Immediately switch off the hydraulic attachment and
the carrier if you detect any leaks in the hydraulic cir-
cuits.
u
Depressurise the hydraulic system (see chapter
De-
pressurising the hydraulic system
).
u
Repair any leaks before operating the hydraulic at-
tachment again.
WARNING
Hot parts
Parts of the hydraulic compactor, hoses, pipes and fit-
tings become very hot during operation. Touching them
may lead to burns.
u
Never touch hot parts.
u
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.
u
Collect any hydraulic oil which escapes.
u
Dispose of it in accordance with the applicable envi-
ronmental regulations.
NOTICE
Hydraulic oil too hot
The temperature of the hydraulic oil must not exceed
80 °C (176 °F). Higher temperature will damage the
seals of the hydraulic parts.
u
Monitor the oil temperature.
u
Shut off the hydraulic attachment and the carrier if
you measure an increased temperature in the tank.
u
Check the hydraulic installation and the pressure re-
lief valve.
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.
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.
u
Never operate the hydraulic compactor in the direct
vicinity of gas pipes.
u
Check gas line position plans of the complete con-
struction area.
NOTICE
Damage to underground cables or pipes
The hydraulic compactor can cause damage to under-
ground cables or water mains.
u
Obtain information on the locations of any under-
ground cables or mains.
n
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.
The preparations required prior to starting the hydraulic
attachment depend on the ambient temperature:
• Ambient temperature below 20 °C (68 °F) (see
chapter
Low ambient temperature
).
