➥ –seeOperation of front/rear additional control circuits on page 3-96
➥ – see chapter 6 “Usable consumer pressure at additional control circuit (option)” on
page 6-7
Clean the quick couplers before connecting the attachment in order to avoid
damage to quick couplers and dirt in the hydraulic oil!
The hydraulic system of the machine is still under pressure even when the
engine is not running: the hydraulic quick couplers can be released, however
they cannot be re-attached because the pressure in the hydraulic lines has not
been released.
• Release the pressure in the sections of the system and hydraulic lines
which are to be opened before fitting or removing an attachment.
• See the Operator's Manuals of the attachment manufacturers for installing
and operating the attachments!
