Knapsack Sprayer Maintenance and Safety

1. Wash the inside of the spray tank with clean water after each use.

3. Do not smoke whilst using the sprayer.

4. Always direct the spray downwind of the operator. Spraying into the wind will result in operator contamination.

5. Store the sprayer in a well ventilated area out of reach of children and away from livestock.

6. Do not expose the sprayer to strong sunlight during storage to prevent deterioration of the tank.

7. The sprayer is designed for the application of agricultural chemicals, disinfectants, cleaning agents etc. Do not use to spray caustic or corrosive solutions.
