FIELD: transport.
SUBSTANCE: invention relates to the maintenance of motor vehicles, in particular to devices for determining the environmental safety of vehicle maintenance, tractors, combines and other self-propelled machines. Screen consists of a rigid base, made in the form of shields. On said substrate, a substrate of a waterproof material is arranged, on this substrate, respectively, there are the lower and upper fixing layers of the screen from the sheets of Whatman paper, which are attached to the base by means of clerical buttons. In addition, the sheets of the Whatman paper of the lower layer are hermetically connected together by adhesive tape.
EFFECT: in combination, it allows to create a screen for determining the environmental safety of maintenance of vehicles, which has improved operational properties, in particular, convenience in use, as it is composite, as well as airtight, which is due to the use of a substrate of waterproof material.
