Operating hints
Agricultural Knapsack Sprayer Model 189325
Dear Customer:
You have purchased one of the best knapsack sprayers on the market today. The Safety Hints from the label
on your sprayer are repeated here for your protection. We urge you to read and observe them.
FOR YOUR SAFETY AND COMFORT:
Before using, filling or cleaning any sprayer, read all parts of the operating hints.
Make sure to set up the sprayer exactly as described in printed operating hints, on reminder tags and/or
stickers.
Wear protective clothing, respirator, gloves, eye protection, etc., whenever using, filling or cleaning the
sprayer.
Periodically re-grease the lid gasket, lid vent and piston sleeve where applicable.
To ensure good performance keep lid vent free of obstruction. Keep connections well thightened.
Service and replace worn parts as required. Make sure the hose loops freely without kinking.
Read and follow all instructions of chemical suppliers.
Do not mix chemical formula inside the sprayer. Use separate container and fill the sprayer from there.
Else -as when applying liquid fertilizers- add these after the water.
Always sift formula through a strainer. If there is none under the lid, use a screened funnel.
Never fill the sprayer with hot liquids. Max. 30°C = 85°F.
This sprayer is made for agrichemicals in their recommended water or oil solutions. Do not use caustic,
corrosive or flammable solutions.
Before cleaning or servicing the sprayer allow all pressure to scape. Do not store or transport the sprayer
under pressure.
Unless spraying is to be resumed within hours, drain chemical formula (dispose of it in proper fashion) after
use and wash the sprayer -including hose, lance and shut-off valve-with plenty of fresh water.
Never store formula in a sprayer for more than a few hours.
Use the sprayer only for jobs for which it was designed. If in doubt, ask your dealer.
Do not leave any sprayer in reach of children or persons not qualified to use it in correct fashion.
When not in use -and especially for prolonged storage- keep your sprayer in a protected place away from
direct solar heat.

(see section For Your Comfort and Safety)
Bear in mind that rubber parts on modern sprayer-e.g. piston sleeves, O rings -resist virtually any
agrichemical. Yet improper use (formulas in greater-than-normal concentration, strong industrial solvents not
commonly known and/or used at the time of manufacture) may cause even the best materials to deform or
wear out prematurely. If this ever happens, call your supplier for support.
