APPLICATIONS & USE FOR YOUR SPRAYER  
Avoid using a sprayer for general cleaning purposes if plant protection or herbicide chemicals have  
already been used in the sprayer. If a sprayer has been used for plant protection or as an herbicide, clean  
the sprayer completely (see cleaning section) before using.  
Plant Food: Use different spray patterns for optimum foliage feeding or for fungicide and pesticide  
application.  
Herbicides: Reduce weeds and unwanted plants but avoid using the same sprayer for plant feeding or  
protection without thoroughly cleaning (see cleaning section) the sprayer first.  
General Household Use: Apply detergents, cleaning solutions, warm water (do not exceed  
120°F/49°C) or nontoxic household cleaning chemicals for carpets, floors, walls, glass, counter tops and  
ceilings. DO NOT use sprayer that has been used with herbicides, pesticides or other toxic chemicals for  
household applications.  
General Outdoor Use: Use the sprayer for cleaning windows or with a detergent for general purpose  
cleaning.

FILLING THE SPRAYER  
Make sure the filter basket is in place to keep debris from entering the tank.  
Determine the amount of mixture needed for your application. Add the proper amount of water to  
the tank. Add the proper amount of chemical to the tank (check the chemical label for proper ratio of  
chemical). Stir mixture in tank with a clean utensil (like a paint stirrer). The tank will hold the 5-gallon  
(20L) capacity plus the chemical.  
It is not necessary to completely fill the sprayer tank with each use. You can fill the tank with only the  
amount needed for each application.  
Always follow the manufacturer’s instructions included on their product label.

SPRAYER COMPONENTS & USE INFORMATION, Continued  
HELPFUL SPRAYING INFORMATION  
Use RAPID pump strokes to prime the pump. You will know the pressure chamber is filling with liquid  
when you feel firm resistance from the pump handle. The air in the pressure chamber is compressed from  
repeated strokes. By pressing the hand lever on the shut-off, the valve opens. For safety lock-off feature  
(no-spraying), pull up on handle and move red locking mechanism into lock-off position as shown in fig.  
1. To disengage, pull up on handle and return red locking mechanism to neutral position as in fig. 3. For  
lock-on feature (continuous spraying), push down on handle and move red locking mechanism into lock-  
on position as shown in fig. 2. To disengage, push down on handle and return red locking mechanism to  
neutral position as shown in fig. 3.  
In the event that the handle becomes stuck in the lock-on (continuous spraying) position and the tank  
pressure needs to be relieved, carefully open the tank and place the wand inside the tank until the  
pressure is relieved.

For easy pump action use the END of the pump handle. The amount of liquid delivered during spraying  
depends on the rate of pump stroke. The fan nozzle tip is rated at .4 gpm at 40psi. This is the nominal  
operating pressure of the sprayer..  
POWDER-BASED CHEMICALS  
Powder-based chemicals (powder mixed with liquids to  
Agitator  
Bar  
make the spraying agent) are usually abrasive and can  
cause wear. When you use a powder-based chemical in  
your sprayer, make sure it is thoroughly dissolved in the  
liquid solution. Thoroughly clean and flush the sprayer  
with water to extend the life of the sprayers parts.  
This sprayer is equipped with an agitator bar which facili-  
tates mixing as the pump is operated.  
CLEANING  
1) Always empty the sprayer and clean the tank thoroughly after each use.  
2) Pump the sprayer handle until all of the contents and air exit through the nozzle (minimum of  
30 strokes).  
3) Fill tank half way with water and pump the water out as explained in step 2 (repeat several times  
as necessary).  
Other Cleaning Hints:  
Improper spray distribution usually means the nozzle is clogged, remove the nozzle and clean it.  
Soap can be added to the water to clean the tank.  
Do not use strong cleaning agents or abrasives.  
If you use a chemical agent to clean the tank follow the manufacturer’s recommendations for the  
disposal of the waste water.  
Follow the chemical manufacturers instructions for clean up.

STORING / MAINTAINING YOUR SPRAYER  
• The sprayer should be stored out of direct sunlight in a cool dry space.  
• Before freezing weather make sure to drain all liquid in the tank, pump, pressure cylinder, hose,  
shut-off valve, wand and nozzle, to avoid liquid expansion and cracking in the sprayer components  
(See “Cleaning” section). Lock the shut-off valve in the “open” position.  
• When service is required call your nearest dealer and always insist on original manufactured  
replacement parts.  
• Inspect the hose, wand, pump, tank and shut-off valve for wear, damage or leaks on a regular basis  
and repair defects promptly.  
• Every year prior to spraying remove felt gasket (see Pump Disassembly and Rebuild) and saturate  
with a light oil. Oil periodically thru out the season as needed.

1) Insure the tank and pressure chamber contents are emptied and pressure  
has been released in the pressure chamber. To release pressure in the  
pressure chamber activate shut-off valve and release all pressure.

Check Valve  
Remove check valve cartridge assembly from bottom of pressure chamber  
utilizing pump handle clip (clip has flat blade incorporated into end). Place  
flat blade into slot in bottom of cartridge and unscrew. Once cartridge has  
been removed it can either be replaced as an assembly or rebuilt. To rebuild  
disassemble two halves of cartridge and replace seal and/or ball (Figure 4 and  
5). The seal mounts inside the larger of the two halves of the cartridge. The  
seal counterbore side mounts into the grooves in the cartridge halve. Pump  
performance my be affected if this is not assembled correctly.

Once the check valve has been removed the plunger cup can be replaced as the  
check valve housing holds the plunger cup in place to the bottom of the pressure  
chamber body. The bottom of the pressure chamber body has a groove in it to  
accept the raised ring on the plunger cup. It is important to insure that these  
two surfaces are aligned and mated before tightening the check valve. Pump  
performance may be affected if this is not assembled correctly.

Gasket  
Slide both the gasket and felt washer off the pressure chamber body (Figure 6).  
Replace felt washer first taking care not to fold over washer as it is worked up  
the pump chamber and into the pump locking ring (figure 7). The felt washer is  
pre-lubricated to provide lubrication between the pressure chamber housing and  
pressure chamber housing gasket. Insure the felt washer is free of contamination  
before installing. Replace gasket into the pump opening in the tank insuring  
the flanged end is up (if this is assembled backwards leakage will occur) (Figure  
8). Insure that the sides of the gasket are inside the tank pump opening and the  
flange is sitting level on the tank pump opening seal surface area.

5) Replace pump assembly into tank and into the piston cylinder which is mount-  
ed on the bottom of the tank. Be careful not to damage the plunger seal as it seats  
into the piston cylinder. It is recommended that you view through the tank fill  
opening while performing this to achieve better alignment. If necessary you can  
also reach in and use your hand to guide the plunger seal into the piston cylinder.
