the solution tank. Wash the tank and all other parts.
• After aerial spraying or dispersing granules,
clear plate and sprayed inside and outside the tank.
• After work loose plate of the chemical tank.
• After cleaning the machine left the engine
running at minimum power for 2-3 minutes.
2. Operation of the fuel system
• Fuel mixed with water or dust is a major cause
of engine problems h, so the fuel system should be
cleaned frequently.
• If the remaining fuel stays in the tank and

work well. Once the machine has not worked one
week all the fuel must be drained.
