2. Designed purpose of use
The AVANT Backhoe 170 is an attachment suitable for use with 200-series 2 AVANT multi purpose loaders.
With the separate control levers and smooth movements the backhoe is easy to use also by inexperienced
operators. Boom movement speeds are steplessly adjustable, which ensures smooth movements and precise
control.
Attaching the backhoe to a loader is quick and easy and takes only a couple of minutes. In addition to the
quick coupling plate of the loader, a supporting bracket is also connected on the loader boom for greater
stability and safety. Also, for more rigid coupling, the bolts on the backhoe can be tightened against the quick
coupling plate of loader.
The powerful, strong, and compact backhoe is well suited for digging and loading of soil to a trailer even at
smaller, confined areas. The frame of the backhoe is as low as possible, which gives unrestricted visibility to
the work area. The boom swing turns hydraulically 120°, and the backhoe is equipped with two adjustable
outriggers and a dozer blade on the front frame are standard equipment. As standard, the backhoe is
equipped with a 250 mm bucket, and also a 400 mm bucket is available as an option. The bucket can be
changed quickly with the pin locking of the bucket.
Using the digger for other than occasional excavations with original buckets, tools or options is prohibited.
Using too large bucket, or handling too heavy loads, cause the risk of tipping the loader-backhoe combination
over. The backhoe must not be used for lifting of objects. The backhoe is not intended for dredging, it must not
be immersed in water.
If the loader is equipped with a cab, the windscreen, or its lower part, must be removed to
make it possible to attach and operate the backhoe. Contact Avant service for further
information or instructions if necessary.
The attachment has been designed to require as little maintenance as possible. The operator can perform
regular maintenance tasks. All repair work can’t be performed by the operator, and demanding repair and
maintenance operations are to be left for professional maintenance. All maintenance work must be done using
proper safety equipment. Spare parts must be identical with original specifications, which can be ensured by
using only original spare parts. A separate spare parts catalogue may be available, consult your Avant dealer.
Familiarise yourself with the manual's instructions regarding service and maintenance. 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.
