1 GENERAL
AGT tractors are designed and produced to provide users with the best reliability and work performance.
However, a lot depends on the user, his approach to work and subsequent maintenance and proper care of
the tractor.
Carefully read instructions for safe use and maintenance and heed to them when handling the tractor to
perform them correctly as the user of your new AGT tractor.
Instructions for use and maintenance are a component part of the tractor and contain vital information for
efficient and safe use and long life expectancy of the tractor.
Keep instructions for use and maintenance in an easy accessible place, so that they are available in
any situation.
Enclose the instructions upon possible sale of the tractor to another purchaser.
If you require expert assistance, contact our service centres, where we will gladly provide support. Upon
contact, provide exact information about your tractor, provided on the identification plate.
When purchasing AGT tractor, you receive documentation, which, along
with instructions for use, includes instructions for use and maintenance of
the engine, warranty and CE declaration of conformity of the product.
NOTE
Due to development and modifications, minor deviances of the text of Instructions for use and
maintenance can occur from the actual state of the tractor. Therefore, we, as the manufacturer, reserve the
right to technical changes of information without prior notification of the customer.
