ASSEMBLY 

INSTRUCTIONS 

You  will  find  your  Sprayer 

assembled and ready to be oper­
ated, less the hose, which is sep­

arate  from  the  lance  and  the 
sprayer pump.  Connect the hose 

to the outlet pump connector and 
to  the  lance,  and  adjust  both 
ends  with  the  two  hose  clamps 
you will find inside the strainer in 

the sprayer cap. 

The straps are padded and pro-

vided with adjusting buckles. 

To assemble the spraying lance, 
press  the  trigger lever  (#6)  and 

tighten the plastic tip nut (#10) to 

the  bronze  lance  pipe.  Lastly, 

release  the  lever. 

(Important: 

never  tighten  tip  nut  without 
pressing the trigger lever) 

The correct operating position is 

when the top of the tank is on the 
same level as the operator neck.
