When working in very dry crop and with heavy dust generation, the diesel engine, the exhaust system and the cooling system must be cleaned several times a day.
Areas where oil and dust sticks may indicate a leak.

► Keep a safe distance from hot surfaces.
► Avoid any contact with hot surfaces.

CAUTION!
