WARNING Hydraulic system under high
pressure
Carrying out repairs on the pressurised hydraulic
attachment may lead to serious injury. Connections
may come loose unexpectedly, parts may move
suddenly and hydraulic oil may squirt out.
►
Depressurise the hydraulic system before carrying
out repairs to the hydraulic attachment or the
carrier (see chapter
Depressurising the hydraulic
system
).
♦
Remove the hydraulic compactor from the carrier
(see chapter
Removing the hydraulic attachment
from the carrier
) to carry out repairs.
WARNING Hot hydraulic oil squirting out
The hydraulic system is under high pressure. If
hydraulic connections come loose or are
disconnected, hydraulic oil will squirt out under high
pressure. Hydraulic lines may spring a leak or burst.
Hydraulic oil squirting out can lead to serious injury.
►
Depressurise the hydraulic system before carrying
out repairs to the hydraulic attachment or the
carrier (see chapter
Depressurising the hydraulic
system
).
►
Depressurise the hydraulic system according to
the manufacturer's safety and operating
instructions for the carrier.
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.
WARNING Hands and fingers being cut off
or hurt
Bores and surfaces can act like a pair of scissors
and cut off or hurt parts of your body.
►
Never use your fingers to check bores or fitting
surfaces.
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.
Sending in the hydraulic
attachment for repairs
NOTICE
Mixed hydraulic oil
Never mix mineral and non-mineral hydraulic oils!
Even small traces of mineral oil mixed in with
non-mineral oil can result in damage to both the
hydraulic attachment and the carrier. Non-mineral
oil loses its biodegradability.
►
Only use one type of hydraulic oil.
♦
Always specify which hydraulic oil has been used
when sending in the hydraulic attachment to have
it repaired.
