We would like to congratulate you on the purchase of your new SP0.  The 

sprayer that allows you the easiest, most comfortable way of carrying out your 
farm, garden, etc. projects with the revolutionary piston diaphragm pump 
(patented), that all but eliminates the problems inherent in most sprayers. As a 
new owner of the skillfully engineered SP0, we strongly recommend you carefully 
read and follow all the information.   

   

HOW TO ASSEMBLE: 

  

   

1.  Attach spray wand to spray gun and tighten firmly.   
2.  Take pump handle Kit 7 (solid) and insert into the tube on the pump lever 

Kit 5 (“T” shape lever on sprayer) you will notice holes drilled through both 
sides of both the pump handle and the pump lever.  Align these holes; 
take the “R” pin provided and place through the holes.  This affixes the 
handle in place and is ready for use.  For storage reverse process and 
then place “R” pin through the pump lever Kit 5 to keep from losing “R” 
pin.   

3.  Instructions for installing shoulder strap plastic buckle:  First put the 

sprayer on a hard flat surface, take the white plastic buckle and while 
holding the sprayer up slightly, place buckle under the tubular metal 
frame.  Slowly push down forcing the frame into the buckle.  Repeat the 
same procedure for the other side.    

   

HOW TO PREPARE FOR USE: 

  

   

1.  Remove cap.   
2.  Mix solution in a separate receptacle, following manufacturer's directions 

on the container.   

3.  Pour pre-mixed solutions into sprayer and cap.   
4.  Place sprayer on back and pressurize tank by pumping approximately 10 

to 15 times.  For best results, the sprayer should be pumped every 5 
seconds on a continuous basis.  This will maintain your spraying pressure.  
If you do not pump, you will not have pressure to spray.    

5.  Always oil the seal on cap of unit as well as the check valve, this will 

extend life of seal and is important for obtaining proper seal with no leaks.   

6.  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 
chemicals neutralized.  Failure to do this could cause you to kill plants that
