5.4.2 Hydraulic support wheels (optional extra)
The attachment can also be equipped with hydraulic support wheel kit A37547, in which case the double
acting rear hydraulics outlet is necessary. The hydraulic fittings of the hydraulic support wheels system are
connected to the rear hydraulic outlet of the loader (optional equipment for loaders).
See the operator's manual of the loader for instructions about how to use the rear hydraulics of the loader.
Disconnecting hydraulic hoses:
Before disconnecting the fittings, place the attachment to safe position on solid and level surface. Turn the
control lever of the rear auxiliary hydraulics to its neutral position.
When uncoupling the attachment, always disconnect the hydraulic couplings before
unlocking the trailer coupling, to prevent hose damage and any oil spills. Reinstall the
protective caps on the fittings to prevent impurities from entering the hydraulic system.
Releasing residual hydraulic pressure:
In case residual pressure is left in the hydraulic system of the attachment, it is often possible to disconnect the
hydraulic couplings, but it may be difficult to connect them the next time. If the fittings will not connect, the
residual pressure must be released by turning the rear auxiliary hydraulics control lever (optional extra) of the
loader, when the engine is turned off. To make sure that there will not be residual pressure in the hydraulic
system of the attachment, shut down the loader engine and move the rear auxiliary hydraulics control lever of
the loader back and forth before disconnecting the couplings.
WARNING
Risk of movement of the attachment and ejection of hydraulic oil - Never connect
or disconnect quick couplings or other hydraulic components while the control
lever of the auxiliary hydraulics control lever is locked on or if the system is
pressurized.
Connecting or disconnecting the hydraulic couplings while the system is
pressurized may lead to unintended movements of the attachment, or ejection of high-
pressure fluid, which can cause serious injuries or burns. Follow safe stopping procedure
before disconnecting hydraulics.
