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 34) .
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
fluoroelastomer material, the O-rings and seals in
the sprayer can degrade and leak.
Important:
Before applying chemicals to the job
site, verify that you have set the proper application
rate prior to filling the tank.
1. Move the machine to a level surface, move
motion-control lever to the N
EUTRAL
position,
shut off the engine, wait for all moving parts to
stop, remove key, and engage parking brake.
2. Ensure that the narrow-spray pattern and
wide-spray pattern levers are in the O
FF
position
and the handle for the drain valve for the tank
rotated 90° counterclockwise to the is
CLOSED
position ( Figure 39 ).

3. Determine the amount of water needed to mix
the amount of chemical needed as specified by
the chemical manufacturer.
4. Open the tank cap on the spray tank ( Figure 39 ).
5. Add 3/4 of the required water to the sprayer tank
through the filler neck.
Important:
Always use fresh, clean water
in the spray tank. Do not pour chemical
concentrate into an empty tank.
6. Rotate the pump-shutoff valve clockwise to the
O
PEN
position ( Figure 40 ).
