Assembly of the backhoe
The backhoe 170 is ready for use as delivered. To mount the backhoe, in addition to the quick coupling and
connecting the hydraulic fittings the supporting bracket (also called the top link) must also be mounted. To
make the coupling of the backhoe 170 tight, on the front side of the backhoe frame there are also four
screws for reducing the slack between the attachment and the loader quick coupling plate.
Mounting the attachment to the loader is quick and easy, but it must be done carefully. The backhoe may tip
over on the loader or the operator, if it has not been properly attached. To prevent hazardous situations,
always follow the attachment mounting instructions provided in the following pages. Also remember the
safety instructions in Section 3.
Beware of the hinged control valve boom of the backhoe. Do not unfasten the valve
boom strap until the backhoe is completely mounted to the loader.

Mounting the backhoe to the loader
The attachment is mounted to the loader boom by using the quick attach plate and the counterpart on the
attachment. In addition to this, a locking bracket must be also installed.
Never move or raise an attachment that has not been locked.
The backhoe is mounted to the loader as follows:
Step 1:
•
Lift the quick attach plate locking pin up and turn it backwards into the slot so
that it is locked in the upper position.
•
Ensure that the hydraulic hoses are not in the way during installation.
Step 2:
•
Turn the quick attach plate hydraulically to an obliquely forward position.
•
Drive the loader onto the attachment.
Step 3:
•
Lift the boom slightly – pull the boom control lever backward to raise the
attachment off the ground.
•
Turn the boom control lever left to turn the bottom section of the quick attach
plate onto the attachment.
•
Lock the locking pin manually.
