Valtra Workshop Manual - BH GIII LINE

The purpose of this Service Manual is to assist Dealers when performing an efficient maintenance of the BH GIII Valtra Series tractors.
A good product's support assumes increasing importance.
Besides selling a good product, good service is indispensable, because only then you can achieve the
ultimate goal which is Customer's satisfaction.
In this context, the maintenance structure provided by the Dealer is of fundamental importance and therefore should only be performed by trained personnel familiar with the different components of the tractor.
Therefore, in addition to taking periodic refresher courses in the AGCO Brazil Training Units, REFER
TO this guide before performing the service whenever you have any questions.
For this, the Manual should always be available at the workshop.
In addition to always keeping it in working condition, the Service Department should be alert for
updates that will be introduced in the tractors and therefore in the Manual
