Make sure to follow the instructions on the packaging of the agricultural chemicals, disinfectants, cleaning agents etc
when pouring them into the 16 Litre Knapsack Sprayer as to avoid damaging the product and/or causing harm to
yourself or those around you.
If you find one of the nozzles becomes blocked during use or doesn’t spray in the nozzle’s pattern, unscrew the nozzle
tip and clean it under running water. Do not try to unblock the nozzle using an object as this may damage the nozzle,
rendering it ineffective.
To operate the 16 Litre Knapsack Sprayer, unscrew the Pesticide Tank Lid (part 38) and fill it through the Pesticide Tank
Filling Filter (part 37) before screwing the Pesticide Tank Lid (part 38) back on. Attach the 16 Litre Knapsack Sprayer to
your back and pump the Pump Handle (part 31) to build the pressure in the Air Chamber (part 32) before spraying.
Once you’ve finished using the 16 Litre Knapsack Sprayer, remove both the Pesticide Tank Lid (part 38) and the
Pesticide Tank Filling Filter (part 37) and wash the Pesticide Tank (part 33) with warm water.
