NorthStar 55 Gallon Spot Sprayer

 

For outdoor use with agricultural pesticides 
and other liquids** 

 

WARNING

 

 

READ and UNDERSTAND the Owner's Manual completely before using this sprayer

.  

Assemble, test, and use only in accordance with the Owner's Manual instructions. 

 

READ and FOLLOW chemical label instructions.

  Pesticides are hazardous chemicals.

  

 

KNOW emergency procedures BEFORE handling chemicals.

  Sprayer leaks, bodily chemical 

contact, poisoning, and spills require immediate response.

  

 

AVOID inhaling, ingesting, or coming into contact with any chemicals.

  

 

WEAR personal protective gear when filling, using, cleaning, and servicing the sprayer. 

 

 

KEEP sprayer and spray materials away from children and pets.

  Pesticides are especially toxic 

to them.

  

 

EXERCISE CAUTION in vehicle handling when towing/hauling a filled sprayer to avoid loss 

of control or sprayer overturning

.

  

 

DO NOT TURN ON POWER to sprayer until ready to spray

 in order to avoid unintentional 

spray release.

  

 

 

Improper use of the sprayer or handling of chemicals could result in serious injury or illness 
to the operator or nearby persons/animals, or could cause damage to the environment. 

 

 

**

 This sprayer is recommended for use in spraying non-flammable liquids such as pesticides, water for plants/trees 

or dust control, ice control chemicals, or water-based non-flammable sealants or stains for outdoor wood surfaces.  
However, WE RECOMMEND THAT THE SPRAYER NOT BE USED FOR OTHER PURPOSES ONCE IT HAS 
BEEN USED FOR SPRAYING PESTICIDES.  Any chemical will leave some residual in the tank liner or sprayer 
components, even after the sprayer has been properly cleaned.  These residual chemicals can have unexpected 
effects on future uses.  For example, spraying water or other liquids that are contaminated with residual pesticide 
may result in unforeseen hazards to plant or animal life.
