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.
u Depressurise the hydraulic system before connecting
or disconnecting the hydraulic circuits of the hy-
draulic 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.
u Collect any hydraulic oil which escapes.
u Dispose of it in accordance with the applicable envi-
ronmental regulations.
5.1 Media/consumables
The following consumables are used when operating the
hydraulic attachment:
5.1.1 Mineral hydraulic oil
All hydraulic oil brands prescribed by the carrier manu-
facturer are also suitable for use when operating the hy-
draulic 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 manu-
facturer are to be taken into consideration.
Optimum viscosity range =30 - 60cSt
Max. start viscosity =2000cSt
Max. oil temperature =80°C
n
Check the oil filter!
An oil filter must be integrated in the tank line of the
hydraulic system. The maximum mesh width allowed
for the oil filter is 50microns; it must have a magnetic
separator.
5.1.2 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.
u 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 Epiroc Customer Center /
Dealer in your area before using other hydraulic oils ap-
proved by the carrier manufacturer. Following initial as-
sembly and after any workshop repairs, our hydraulic at-
tachments are subjected to a test run on a test bed pow-
ered by mineral oil.
