Belarus 921.6 Operator's Manual page 7

Introduction
The Operation Manual is intended for familiarisation with the BELARUS-921.6 tractor's de-
sign, operation and maintenance rules.
Carefully study this Manual and the Engine Operation Manual 245 S4-0000100 OM,
which are delivered with your tractor. This will help you to familiarise yourself with the tractor's
proper operation and maintenance methods.
Non-compliance to this instruction can lead to an operator's injuries or the tractor's
breakages, or damage to other parties.
The tractor operation, servicing and repairs shall be performed only by employees, who are
familiar with all of its parameters and specifications, and who are informed about necessary safety
requirements to prevent accidents.
Because of the tractor's continuous development, some of its units and parts design
might be altered and these alterations might not be described in this Operation Manual.
The manufacturer is not responsible for possible operator injuries and tractor breakages
caused by user-defined alterations of any units design. Additionally, if the user introduces any
alterations into any units during the warranty period, the tractor becomes excluded from war-
ranty maintenance.
