Assembling the hydraulic hoses to silage forks
1. Choose a level, well lit, and clean area for installation. Lower the attachment completely on the ground or
on a pallette, shut down the loader engine and release any residual hydraulic pressure. Also remember
safety instructions from pages 4 and 5.
2. Block the movements of the grapple and carefully remove the protective plastic covers from top of the
hydraulic cylinder. Scrape the paint off from the contact surface. Make sure that impurities will not enter
the cylinder.
When removing the plastic covers from the cylinder, the grapple will move very easily.
As the grapple moves, some oil will be ejected from the cylinder. Use additional
supports, e.g. blocks of wood, or lifting equipment, to prevent the grapple from moving
inadvertently. Beware of the possible oil spray from the cylinder.
3. The so called banjo fittings at the end of the hydraulic hoses
are connected to the cylinder with hexagonal screw type
fittings. Slide a seal ring on both sides of the banjo fitting and
tighten to position shown in figures. Note the welding on the
cylinder and make sure that the hose is not in contact with
the welding.
4. Install the hose clamp to the attachment, but do not tighten
the clamp.
5. Install the hydraulic couplings:
Conventional type quick couplings:
-
Slide the protective caps to the straight ends of the
hoses. Set a seal ting in between the quick coupling and
tighten quick coupling to the hose.
-
The coloured cap should be fitted to the hose connected
to the piston side of the cylinder, i.e. the fitting closer to
the loader.
Installing the multiconnector coupler:
-
Install the parking stand of the multiconnector to the
hydraulic cylinder.
-
Place the multiconnector fitting to the loader connector,
but do not lock the connector to the loader.
-
Fit the connector closer to the loader to the lower fitting
of the multiconnector.
Do not lock the multiconnector to the
loader until the hoses are installed
and all fittings have been tightened!
