Designed purpose of use
The AVANT backhoes 220 and 250 are attachments designed and manufactured to be used with AVANT
multi purpose loaders. They are digging attachments with high reach, and they are suited for hard
construction work, to be used in digging and loading of soil to a trailer, for example.
The slewing range of both models is full 180° with constant speed. The backhoe is easy and quick to mount
on the loader, and the hydraulically operated locking bar, which mounts on the loader chassis, ensures
stability during digging and enables efficient work. In addition, manually adjustable support jacks are a
standard feature.
The backhoes are equipped with a hydraulic control valve unit to control the movements of the backhoe. The
backhoes can be operated by standing next to the equipment, or directly from the driver’s seat, when the
control valve unit is mounted on the loader boom. A comprehensive range of buckets is available for various
jobs. Also a grading bucket with hydraulic tilting is available, for which the backhoe is equipped with
necessary components as standard. The use of the backhoe as a lifting crane is prohibited due to a risk of
tipping the loader-backhoe combination over. The backhoes are not suitable for dredging.
The attachments have been designed to require as little maintenance as possible. With the backhoe, an
installation kit is provided, which is mounted at the first use. Regular maintenance tasks can be performed by
the operator. More demanding tasks must be left to qualified professionals. Appropriate protective equipment
and original spare parts must be used for the maintenance. Read the maintenance and servicing instructions
in this manual. Please contact your AVANT retailer if you have additional questions about the operation or
maintenance of the equipment or if you require spare parts or maintenance services.

Safety instructions for the backhoes
Please bear in mind that safety is the result of several factors. The loader-attachment combination is highly
powerful, and improper or careless use may cause serious personal injury or property damage. Due to this,
you should carefully familiarise yourself with the manuals of both the loader and the attachment before
starting operation. Do not use the attachment if you have not familiarised yourself with its operation and the
related hazards. The purpose of these instructions is to help you to:
•
use the equipment in a safe and efficient manner
•
monitor and prevent any hazardous situations
•
keep the equipment intact and ensure a long service life
•
When mounting the attachment to the loader, ensure that the locking pins of the
loader's quick attach plate are in the lower position and that they have locked the
attachment to the loader. Always mount also the supporting bracket. Carefully
read the instructions of how to attach the backhoe to the loader.
