Step 1: 

Attach the axle to the trailer frame with (4) bolts 

& nuts as shown. 

 

 

 

Step 2: 

Slide a wheel onto the hub of the axle and use 

the wheel nuts to hold the wheel in place. Re-

peat for other side. 

 

 

Step 3: 

The left and right boom mounting brackets are 

to be mounted on the trailer frame. Use 4 bolts 

and nuts to secure them in place. 

 

Step 4: 

Center the boom tube on the boom mounts 

and secure in place with the (2) round U-bolts 

and whiz nuts provided. 

Make sure the U-bolts are positioned within the 

grooves of the grommets on the boom tube. 

 

NOTE: 

The purpose of these grommets is to 

prevent metal-to-metal contact between the U-

bolts, boom tube and boom mounting brackets.

 

 

The grommets will ‘compress’ as you tighten 

the whiz locknuts 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 grom-

met. 

**DO NOT OVER TIGHTEN the whiz lock-

nuts, as this may cause the boom tube to 

flatten slightly! 

 

See Below for end nozzle attachment. 

End Nozzle Assembly Procedure 

For Boomless “Wet” Boom 

Your boom will come with the (2) end nozzle assemblies 

NOT affixed to your boom tube. Follow the instructions 

below to attach these properly to the boom tube, as 

shown. 

Assembled 
End Nozzle 

1.  Start by sliding Item 4, 3, 2 onto the boom tube 

(Item 1) as shown, leaving about 1/2” to 3/4”     

between the end of the boom tube and Item 2. 

Make sure the “Long” portion of Item 3 is facing the 

nozzle end. 

2.  Slide the (complete) end nozzle assembly onto the 

stainless steel boom tube, with a somewhat 

“twisting” motion, so that the end face of the boom 

tube “butts” up against the surface face inside the 

nozzle body. 

3.  Now push the “compression olive” (Item 3) against 

O-ring (Item 2) and slide (both) into the nozzle 

body opening firmly. 

4.  Firmly tighten flynut (Item 4) onto threads of      

nozzle body. 

5.  Repeat for other side. 

 

NOTE: If water is shooting back on the boom tube, 

item 2 is not in the correct placement. 

Item 2 is shipped inside of 

the end nozzle assembly. 

Remove & place on tube.
