6.2.2 Front-end excavator
Coupling
For coupling and uncoupling procedures please refer to the
description of the multi-purpose bucket in section 6.2.1 (1)
...(10), except that all four hydraulic hose sleeves on the
front-end excavator need to be attached to the connectors
on the quick coupler assembly.
Ensure that the hoses on the right of the front-end excavator
are attached to the connectors on the right of the quick
coupler assembly and that that both hoses on the left of the
front-end excavator are attached to the connectors on the
left of the quick coupler assembly. Make sure that the
hoses do not cross.
NOTE
If you cross attach the hydraulic hoses, the
motion of the front-end excavator boom and
bucket will not correspond to the description on
plate (2-1/5).
DANGER
The lock pins of the quick coupler must be
inserted in the lifting holes on both sides of the
front-end excavator attachment and must protude
visibly when viewed from the side.
ATTENTION
- Ensure that the engine is idling while locking
the front-end excavator in order to reduce the
insertion speed of the lock pins and thus
prevent leakages.
- When attaching hydraulic hoses pay attention
to cleanliness of the joint and ensure that
connectors are seated properly.
Uncoupling
For uncoupling procedures see the description of the multi-
purpose bucket (section 6.2.1), however, ensure that all
four hydraulic hoses of the front-end excavator are
disconnected from the four connectors on the quick coupler.
ACHTUNG
- Ensure that the engine is idling while unlocking
the front-end excavator in order to reduce the
retraction speed of the lock pins and thus
prevent leakages.
- Ensure that an attachment is fitted before
engaging the hydraulic quick coupler.
NOTE
The type plate is on the right of the arm near the
coupler frame.
