OPERATING THE SPRAYER

   CAUTION

Always wear adequate protective clothing 

including long pants, substantial protec-

tive footwear, gloves, and eye protection 

when mixing chemicals or spraying.  Wear 

a mask or face shield if necessary.  

1.  Calculate the amount of chemical needed to 

complete the job using the application rate, 

and only mix what is needed.

2.  Fill the sprayer where spills cannot harm the 

vegetation.  

NOTE:  

If you are using a wettable powder be 

sure to mix the material well before spraying.  

This can be done by using the spray wand to 

stir the material for a period of time to make 

sure it is thoroughly mixed.

3.  Visually inspect the hoses and nozzles on the 

sprayer for leaks or damage before spraying.

4.  Check spray tip height and spray pattern on 

the spray boom.  Tips should be about 17” 

from the ground to the base of the tip.  Spray 

tips should be aligned so the spray pattern is 

perpendicular to the direction of travel.

5.  Release the air pressure in the spray wand to 

initiate the check valves in the spray boom by 

opening the spray wand valve (P/N B017) until 

spray material flows from the wand.   

NOTE: 

 Never let the sprayer operate in one 

spot, always turn the pump off when the tractor 

is stopped.

6.  Use the toggle switch to turn on the spray 

boom when actively moving and ready to 

spray.   

NOTE:  

Turn the sprayer off during turns to 

avoid double spraying.

   CAUTION

Maintain a steady and slow speed around 

2.5 MPH (4 km/h) when spraying.  Be aware 

of changing weather conditions.  Any blow 

back on the operator can be harmful.  The 

chemicals can be absorbed via skin and 

inhalation.

INSTALLING THE WIND SCREEN

Depending on the wind condition you may, or may 

not, want to install the Wind Screen to prevent 

spray drift.  Remove the Wind Screen when the 

sprayer is not in use to protect it from damage.  To 

install the screen, hook the rings over the S-hooks 

mounted on the Wind Screen Support Brackets.  

CLEANING THE SPRAYER

After every spray session, it is recommended to 

follow these steps to clean the sprayer.  

1.  Dilute the remaining chemical and spray this 

mixture on the area just treated until it is gone.

2.  Clean the sprayer and rinse with clean water. 

NOTE: 

Always follow the spray manufacture’s 

directions to properly neutralize the chemicals  

if necessary.  

3.  Operate the spray nozzles until all water is 

gone.
