MAINTENANCE

5.
Since the sprayer needs little maintenance, if you follow the steps mentioned in this manual its lifespan will be very long.
Do not keep the sprayer with pressure after finishing your spraying job, release the pressure through the nozzle depressing the trigger, then take the
cap and strainer out and pour the remaining solution. Now rinse system with fresh water as follows:
Pour approximately 1/2 gallon of fresh water in the tank, pressurize and flush, the pumping system by pressing trigger at least 2 minutes, then drain all
remaining water.
Carrying straps are made of non-absorbent materials, nevertheless in case of solution spillage, wash them with fresh water to eliminate all risk of skin
irritation.
A unit that has been used with herbicides should never be used to spray insecticides, unless the sprayer has been properly cleaned and all other chemi-
cals neutralized. Failure to do this could cause you to kill plants that have been sprayed.
Always follow manufacturer's instructions of the chemicals in use to avoid accidents and take maximum advantage of the product.
Store your sprayer clean, empty and dry in a place protected from sunlight.
