DANGER
•
The work equipment coupling and uncoupling operations
must be carried out on a firm and level surface.
•
The method described is valid for any rear equipment
whose operation does not require the use of pressurized
oil.
•
Before starting work, make sure that the coupling pins are
completely engaged in the equipment seats.
The mechanical rapid coupling device (1) of the rear equipment
has been developed by Komatsu to facilitate the coupling and un-
copuling of the various pieces of equipment.
It is a practical and user-friendly device and therefore it makes it
possible to considerably reduce the time required to change the
equipment.
Furthermore, the rapid coupling device (1) ensures the coupling
of several types of equipment, for example special buckets, drills,
hydraulic hammers or other equipment, provided that their instal-
lation is authorized by Komatsu. If necessary, the bucket can be
attached to the rapid coupling (1) even in reversed position, as
shown in Fig. A.
For the assembly or disassembly of the rapid coupling device (1)
on/from the backhoe arm, keep to the indications given in para-
graph “3.13.5 CHANGING THE BACKHOE BUCKET”.
The rapid coupling device (1) features (like for a simple digging
bucket) two different positions for the coupling to the backhoe,
which can be selected according to the operation to be performed
and to the equipment to be used:
Pos. 1: Normal digging position
Pos. 2: Indicated for operations on vertical walls, ensures the
maximum swing and the maximum digging height along
the wall.

•
The slot (C) serves for the insertion of the release lever,
which must always be positioned on the outside of the ma-
chine, as shown in Fig. B.

PLING AND RELEASE PROCEDURE”.
