(12 Volt, 55 Gallon 3 Point Sprayer  

w/3-Nozzle ‘Boomless’ Boom Assembly) 

Information About the Sprayer 

In  this  pump  system,  solution  is  drawn  from  the  tank  and 

forced to a planned source, such as boom nozzles. 

 

The ‘directo-valve’ is the on/off control which allows the oper-

ator to manually control the solution going to the boom. 

 

Assembly Instructions 

Most of the sprayer has been assembled at the factory. 

 

Attach  the  boom  to  the  boom  mounting  tabs  with  the  (2)  u-

bolts  and  (4)  whiz  locknuts. Make  sure the  u-bolts  are  posi-

tioned within the grooves of the grommets on the boom tube. 

 

NOTE: The purpose of these grommets is to prevent met-

al-to-metal contact between the u-bolts, boom tube and 

boom mounting brackets. 

The grommets will ‘compress’ as you tighten the whiz lock-

nuts onto the u-bolts. Tighten just so that the boom tube will 

NOT rotate within the grommets. Alternate the tightening of 

the locknuts to provide even pressure on the grommet. 

**DO NOT OVER TIGHTEN the whiz locknuts, as this may 

cause the boom tube to flatten slightly! 

 

Follow  the  instructions  on  page  2  to  assemble  the  end noz-

zles onto the boom. 

 

Attach  the  boom  feeder  hose  to  the  boom  after  routing  it 

through the underside of the carrier frame as needed. Secure 

in place with a hose clamp provided. 

 

Connect the electrical hook-up to the end of your pump and 

clip the clips to a fully charged battery.   

Caution: When fully filled with water, this sprayer will 

weigh approx. 640 lbs.. Consult the owner’s manual for 

your vehicle to verify that you are within it’s load carrying  

capacity.
