Step 4: Fitting the support bracket
•
Lift the backhoe slightly off the ground. Remove
the pin from the loader side of the supporting bracket and place the
bracket on the bracket of the loader boom.
•
Tilt the backhoe to align the holes.
•
Fit the locking pin through the holes and lock it
with the cotter pin.
Do not use your fingers to check the alignment of the support bracket. Movement of
the backhoe creates a pinch or shear hazard.
5.2.1.
Taking the backhoe off from the loader
When taking the backhoe off from the loader for storage, to ensure its stability, do as follows:
1. Open the hydraulic locking completely (see section 5.4)
2. Lower the outriggers of the backhoe on even and solid
surface.
3. Turn the slewing of the backhoe to its middle position and
lower the bucket just slightly above the ground, as shown
in the adjacent figure.
4. Turn the auxiliary hydraulics control of the loader off.
5. Put the control valve of the backhoe to its holder on the
backhoe. Note that the backhoe may move if the control
levers are actuated.
6. Turn the loader boom tilting so that it s possible to
remove the pin of the support bracket.
7. Shut down the loader engine and remove the support
bracket
8. Tilt the backhoe to a slightly forward position so, that the bucket will now lower on the ground.
9. Disconnect the hydraulic fittings as shown in section 5.3. This procedure will release the pressure left in
the backhoe and the bucket and the backhoe booms will lower to a stable position.
10. Open the quick coupling and take the backhoe off from the loader.
5.3.
Connecting and disconnecting the hydraulic fittings
Before connecting or disconnecting hydraulic fittings, shut down the loader engine and move the auxiliary
hydraulics lever on the loader to its extreme positions a few times and also move the control levers of the
backhoe. This way, there will be no remaining pressure in the system and the fittings are easy to connect.
To connect and disconnect the fittings, move the collar at the end of the female fitting. The hoses should be
connected so that the male fitting of the backhoe is connected on the loader to the fitting with coloured cap.
The second hose is connected on the single male fitting of the loader.
When disconnecting the fittings, first move the auxiliary hydraulics control levers as well as the levers of the
backhoe. Lower the backhoe as described in the previous section so that there will be no residual pressure
in the system and the backhoe will be stable during storage.
If there is residual pressure in the hydraulic system of the backhoe due to its position, it is often possible to
disconnect the fittings, but connecting them the next time may be difficult. If the fittings will not connect, the
residual pressure must be released. First move the control levers of the backhoe. Note that the backhoe may
move. If this doesn’t help, while the backhoe is coupled with the loader, its bucket may be pressed against
the ground with the loader boom.
