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 Sprayer Nozzle Application Rate
(page 37).
Filling the 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:
Do not use brackish or reclaimed
water in the spray system.
1. Move the machine to a level surface, move

shut off the engine, wait for all moving parts to
stop, remove key, and engage parking brake.
2. Ensure that the 3 boom sprayer-control valves
are in the O position.

3. Adjust the tank shutoff valves for the spray tank
that you are using; refer to
Tank Shutoff Valves (page
4. Determine the amount of product and water
needed to mix the amount of chemical solution
as specified by the chemical manufacturer;
refer to Calculating the Amount of Product for a
Solution of Chemical (page

through the filler neck.
Important:
Always use fresh, clean water
in the spray tank. Do not pour chemical
concentrate into an empty tank.

Note:
The water in the tank will circulate.
11. Add the specified amount of chemical
concentrate to the tank as directed by the
chemical manufacturer.
Important:
wettable-powder chemical, mix the
powder with a small amount of water to form
a liquid slurry before adding the chemical
mixture to the tank.
12. Add remaining water to the tank and install cap
onto the filler neck of the tank.
Note:
Allow the content of the sprayer tank to
mix thoroughly.
Important:
Before applying chemicals to the job
site, adjust the sprayer-pressure with the throttle
valve according to the sprayer nozzle application
rate.
Spraying with the Sprayer Boom
Important:
To ensure that your chemical solution
remains well mixed. For the agitation feature
to work, set the sprayer-pump switch to the O
position, pull back the tank-agitation lever, and run
the engine at high idle. If you shut off the machine
and agitation is needed, leave the motion-control
lever in the N
