Step 5:
Complete the assembly by tightening four
M16 screws against the quick coupling
plate of the loader. Use an 8 mm Allen
key.
Backhoe
can
be
operated
without
tightening these screws, but more rigid
coupling will improve overall performance.

Connecting and disconnecting the hydraulic hoses
On the 200 series 2 loaders the hydraulic hoses are connected using the multi connector system.
VAROITUS:
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.
Keep all fittings as clean as possible; use the protective caps on both the attachment and
the loader. Dirt, ice, etc. may make using the fittings significantly more difficult. Never
leave the hoses hanging on the ground; place the couplings onto the holder on the
attachment.
Connecting the multi connector system:
1.
Align the pins of the attachment connector with corresponding
holes of the loader connector. The multi connector will not
connect if the attachment connector is upside down.
2.
Connect and lock the multi connector by turning the lever towards
the loader.
The lever should move easily all the way to its locking position. If the lever does not slide smoothly, check the
alignment and position of the connector and clean the connectors. Also shut down the loader and release the
residual hydraulic pressure.
