• Alternative 2 (cab under category 2): Protection against hazardous substances (agricultural chemicals
etc.) in the form of aerosols and fumes is not provided. Tractors equipped with a cab are not intended
for spraying pesticides without additional protection. Personal protective equipment must be used
according to the chemical manufacturer's recommendations.
Protection against dust (category 2 of standard EN15695-1:2009) is provided under the following
conditions:
• all roof hatch, cab doors and cab windows are closed
• cab ventilation is running
• air filter is clean and is serviced under maintenance interval (refer to service guide). When replacing
the filter, only a filter certified for at least category 2 cabs is permitted. Activated carbon filters do not
improve the cab's level of protection. Always refer to the user instructions provided with the filter.
• Alternative 3 (cab under category 4): The cab is equipped with protection against hazardous substances
(agricultural chemicals etc.) in the form of dust, aerosols and fumes. For pesticide spraying, tractors
equipped with a cab must also have a specially designed filter for category 4 cabs.
This protection (category 4 of standard EN 15695-1:2009) is provided under the following conditions:
• all roof hatch, cab doors and cab windows are closed
• cab ventilation is running
• air filter is clean and is serviced under maintenance interval (refer to service guide).
Given the risk associated with contaminants entering the cab when opening the door to enter or exit
the vehicle, this protection is designed to supplement, but not replace, the use of personal protective
equipment when working in an environment with aerosols and/or fumes, such as pesticides. Personal
protective equipment must be used according to the chemical manufacturer's recommendations.
When replacing the filter, only a filter certified for at least category 4 cabs is permitted.
Always refer to the user instructions provided with the filter. Once spraying operations are complete,
return the special filter to its case and replace it with a standard anti-dust filter.
