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 oil squirting out can lead to
serious injury.
►
Depressurise the hydraulic system before
connecting or disconnecting the hydraulic circuits
of the hydraulic attachment (see chapter
Depressurising the hydraulic system
).
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.
Media/consumables
The following consumables are used when operating
the hydraulic attachment:
Mineral hydraulic oil
All hydraulic oil brands prescribed by the carrier
manufacturer are also suitable for use when
operating the hydraulic attachment.
However, the oil should comply with viscosity class
HLP 32 or higher.
In summer and in hot climates, oils of viscosity class
HLP 68 or higher should be used.
In all other respects the regulations of the carrier
manufacturer are to be taken into consideration.
= 30 - 60 cSt
Optimum viscosity range
= 2000 cSt
Max. start viscosity
= 80 °C
Max. oil temperature
Special conditions apply to using the hydraulic
attachment at low temperatures (see section
Low
ambient temperature
).
♦
Check the oil filter!
An oil filter must be integrated in the return circuit of
the hydraulic system. The maximum mesh width
allowed for the oil filter is 50 microns; it must have a
magnetic separator.
Non-mineral hydraulic oil
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.
If you are using non-mineral oil it is imperative that
the name of the oil in use be indicated when returning
the hydraulic attachment for repair.
In order to protect the environment or on technical
grounds, hydraulic oils are currently being used which
are not classified as HLP mineral oils.
Before using hydraulic oils of this kind it is imperative
to ask the carrier manufacturer whether operations
with such fluids are possible.
Our hydraulic attachments are basically designed
for use with mineral oils. Consult the Atlas Copco
Customer Center/Dealer in your area before using
other hydraulic oils approved by the carrier
manufacturer. Following initial assembly and after
any workshop repairs, our hydraulic attachments are
subjected to a test run on a test bed powered by
mineral oil
.
Engine oil
♦
When handling oils observe the safety instructions
that apply to these products.
♦
Replace the oil in the PermanentLube system by
Atlas Copco Cobra & Compactor Impact-Oil, part
number 9234 0012 03.
