Bucket installation with quick release system
The quick release system consists of the special attachment car-
rier mounted to the dipper arm. The moveable plate (1) on the car-
rier locks the system in place. Attachment carrier and bucket have
tapered pins (2) and fitting grooves (3) for fastening.
The locking system works mechanically (spring). Hydraulic unlock-
ing is controlled from the operator's stand with the unlocking swit-
ches (1) and (3).
Fastening the bucket
1 Position the excavating equipment to the bucket to be installed
(Fig. A).
2 Align the tapered pins on the equipment carrier to the fitting
groove on the bucket (Fig. B).
3 Extend the dipper arm (Fig. C).
4 Once the tapered pin is located in the fitting groove the attach-
ment carrier automatically locks the bucket.
Removing the bucket
1 Lower the bucket to level ground.
2 Press unlocking switches (1) and (3) together.
3 This lifts the moveable plate (1) and unlocks the system. At this
time the bucket is no longer positively connected, the arm can
be retracted and another attachment can be fastened.
WARNING!
In order to rule out any risk of an accident caused by
unhooking of the bucket, move the bucket (slightly above
the ground) to check whether the locking is correctly posi-
tioned. Excessive clearance indicates that the locking sys-
tem in position (4a) has failed and the unit is held in safety
position (4b). In this case the process must be repeated,
until the bucket is properly locked in position (4a).
WARNING!
The bucket may only be unhooked when it is resting on the
ground.
