CHEMICAL RECOMMENDATIONS

Problem

Solution

1. If only air is coming out when you 
spray that means that the supply tube 
has fallen off or isn’t attached correctly. 

Unscrew and pull the hose off of the tank. Then 
unscrew the pump handle from the tank and get 
the supply tube out from inside. Reattach the 
supply tube onto the hose, insert back into the 
tank, and screw the hose back on.

2. Sprayer is not holding pressure, 
check the seals on the pump and make 
sure they are lubricated. 

(Recommended lubrication is 
petroleum jelly.)

A cylinder O-ring is located at the top of the pump 
and needs to be lubricated often. A check/mono 
valve is at the bottom of the cylinder and also 
needs lubrication. The 

fi

 nal seal is on the inside of 

the pump. 

1. To access this, unlock the pump handle and pull 
it out as far as it will go. 
2. With a 

fl

 at head screwdriver, push down on 

the tabs on each side of the pump to release the 
locking cap. 
3. Pull up on the handle and the plunger assembly 
will come out of the pump cylinder. The gasket is 
located on the end of the plunger assembly. 
4. To reassemble, insert the plunger assembly into 
the cylinder and snap the cap back into place. 

3. The sprayer is producing a bad spray 
pattern.

Check the hose, wand, and nozzle for any clogs. 
Clean all these parts properly. 

Recommended for use with:



Most chemical weed killers



Most chemical insecticides/pesticides



Mild cleaners (such as dishwashing 

detergent, and most disinfectants)

Some sprayers can handle tougher 
chemicals. Call or email us for a 
recommendation for your project!
