WARNING  
Oil cap gasket before using and  
lubricate weekly so the gasket will seal  
properly and prevent chemical leaks.  
On the same side where the pump is  
located, place the round portion of the  
pump handle through the hole on the  
base of the sprayer. When it is almost  
through, place the bent portion of the  
pump lever through the hole on the flat  
portion of the handel. Once through, place  
on one washer and, then the locking pin.  
(See figure 3). The round tube comes  
through the base of the unit and extends  
out 6.4mm (1/4”), exposing the hole  
drilled through the tube. Place on the  
other washer and the other holding pin.  
The pump handle assembly is now  
complete.  
Oil check valve and maintain breather  
hole clear of debris. Your failure to oil  
may can cause the tank to collapse  
and crack due to vacuum created by  
pump lubricate with "3 and 1" oil.

WARNING  
• Never use caustic or corrosive materials in the sprayer, which  
could result in damage to the unit.  
Oil cap gasket before using and lubricate weekly so the  
gasket will seal properly and prevent chemical leaks.  
HOW TO ADJUST THE NOZZLE  
• To adjust nozzle, tighten cap (turn clockwise) for fine atomized  
spray, or loosen (turn counter-clockwise) for coarser spray or  
solid stream.  
Oil check valve and maintain breather hole clear of debris.  
Your failure to oil may can cause the tank to collapse and  
crack due to vacuum created by pump lubricate with "3 and  
1" oil.  
HOW TO PREPARE YOUR UNIT FOR USE  
• Normal working pressure should be from 25 psi to 40 psi. Too  
much pressure will waist chemical and over apply, as well as  
causing potential damage to pump tube.  
IMPORTANT  
Before using, oil cap gasket, felt pump washer, and check valve,  
and maintain breather hole clear of debris. Your failure to oil,  
clean check valve, and maintain breather hole open to allow air  
into the tank, can cause the tank to collapse and crack, due to  
vacuum created by pump.  
• Pump occasionally to maintain the desired spraying pressure.  
RECOMMENDED APPLICATIONS FOR  
"LAWN AND GARDEN" OR "AGRICULTURE" USAGE.  
1. Before you remove cap, be sure there is no pressure in the  
tank. in order to release pressure, invert unit upside down and  
squeeze spray pistol (aim away from you). Pressure will  
escape; when hissing stops, all pressure has been released.  
Remove pump assembly by turning counter-clockwise. The  
pump handle has two locking positions, one turning clockwise  
and one counter-clockwise.  
Herbicide : Yes  
Insecticides/Pesticides : Yes  
Fertilizers : Yes  
Chlorine based : Yes  
Diesel : Yes  
Wettable Powder : Yes  
Stains & Sealers : Yes  
Oil Based : Yes  
2. Remove cap.  
3. A unit that has been used with herbicides should never be used  
to spray insecticides, unless the sprayer has been properly  
cleaned and all other chemicals neutralized. Failure to do this  
could cause you to kill plants that have been sprayed. Consult  
with the manufacturer of the chemicals in use to obtain proper  
instructions.  
Solvent-Based : Yes  
Viscous : No  
4. Always oil the gasket on the cap of the unit, as well as the  
check valve. This will extend the life of the seal and is important  
for obtaining a proper seal with no leaks.  
5. Mix solution in a separate container, following the  
manufacturers’ directions.  
6. Pour pre-mixed solution through strainer into tank. Reinstall cap  
tightly.  
7. Place sprayer on back and pressurize tank by pumping  
approximately 5 to 11 times.  
8. You will need to pump occasionally to maintain the desired  
spraying pressure.  
9. For best results, the sprayer should be pumped every five  
seconds on a continuous basis. This will maintain your spraying  
pressure. If you do not pump, you will not have pressure to  
spray.
