Do not use the automatic locking of the locking pin with the backhoe. The centre of
gravity of the backhoe is at relatively high, which creates a risk of the backhoe tipping
over.
Before moving or lifting the attachment, ensure that the
locking pin is in the lower position and comes through the
fastener.
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. A small
movement of the backhoe could pinch or shear a finger.
Step 5: Tightening the quick coupling plate
•
To remove the slack between backhoe and the loader quick attach
plate, use an 8 mm allen key to tighten the four screws on front of the
backhoe frame.
•
Tightening is recommended when using the backhoe for longer periods.

Connecting and disconnecting the hydraulic quick couplings
The hydraulic couplers of the backhoe should connected so that the male coupling is connected to the
coupling marked with a coloured cap on the loader. The other hose is connected to the tank line (free return
line). Before connecting or disconnecting hydraulic couplings, shut down the loader engine and move the
auxiliary hydraulics pedal on the loader to its extreme positions a few times. This way, there will be no
remaining pressure in the system and the fittings are easy to connect.
The hoses can be connected by pushing the fitting in the counterpart. When connecting and disconnecting
the 200-series hydraulics quick couplings, you should pay attention to their locking. The locking prevents the
female and male fittings from being disconnected from each other by accident when the attachment moves.
The fitting collar may also turn uninentionally into the locking position, making it impossible to connect or
disconnect the fittings.
In the 200-series equipment, there is a small groove in the collar of all
female fittings and a small ball below the collar. When the fittings need
to be disconnected, the above-mentioned groove and ball need to be
aligned. Then, the grooved collar of the female fitting is pulled
downwards to disconnect the fittings from each other.
