Conventional quick couplings (alternative couplings for some loader models):
Before connecting or disconnecting the standard quick couplings, the residual pressure must be released
as shown below. The conventional quick couplings will not connect, if there is pressure in the hydraulic
system.
To connect and disconnect the standard couplings, move the collar at the
end of the female fitting. The hoses should be connected so that the
fitting equipped with a coloured cap is connected to the corresponding
fitting of the loader. Note that the protective caps on the loader and the
attachment can be fastened to each other during operation to reduce the
accumulation of dirt. When disconnecting the standard quick couplings a
small amount of oil may drip from the couplings. Wear protective gloves
and have some cloth at hand to keep the equipment clean.
Keep the fittings as clean as possible; use the protective caps for the quick
couplings 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 them on top of the equipment.
Releasing residual hydraulic pressure:
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 auxiliary hydraulics control lever of the loader to it’s extreme positions
before disconnecting the couplings. If the fittings will not connect to the loader, the residual pressure must
be released. The residual pressure must be released before handling or going near the moving
components of the attachment and before storage of the attachment.

Electric connection
To select the operating mode of the plow, there is a hydraulic valve on the plow. The electric harness of the
valve is connected to the loader. There are two alternatives for connecting the electric harness:
■
Th optional attachment control switch pack, available
for 400-700 loader models, is recommended. In this
case, the connector of the attachment is connected
to the socket located next to hydraulic connectors on
the loader boom. The separate cable set is not
needed when using attachment control switch pack.
To control the blade, the switch number 1 is used,
other switches are not in use.
■
Alternatively the cable harness A35358, delivered
with the attachment and equipped with a two-position
switch, is connected to the power plug near the
control panel of the loader. Select the location of the
switch in the cab to ensure that it is easily accessible
but will not be used inadvertently.
■
The operating modes and controls are shown in
chapter 6.2.2.
