Using the Sprayer
Before Operating the Sprayer
Some chemicals are more aggressive than others
and each chemical interacts differently with various
materials. Some consistencies of sprayer chemicals
(e.g. wettable powders, charcoal) are more abrasive
and lead to higher-wear rates. If a chemical is
available in a formulation that would provide increased
life to the sprayer, use this alternative formulation.
Calibrate the sprayer before you start the spray
application; refer to
Calibrating the Sprayer (page
Filling the Spray Tank
Important:
Ensure that the chemicals that you
are using in the sprayer are compatible for use
with O-rings and seals made from fluoroelastomer
material (refer to the chemical manufacturer's
label; it should indicate if it is not compatible). If
you use a chemical that is not compatible with
