HOW TO ASSEMBLE  
1. Attach spray wand to spray gun and  
tighten firmly.  
Hose clamps are not completely tight.  
Please tighten hose clamps prior to using.  
Hose clamps are left loose to extend life  
of gaskets and fittings.  
2. Take pump handle RMKIT 7 and insert  
into the tube on the pump lever RMKIT  
5 (“T” shape lever on sprayer), you will  
notice holes drilled through both sides  
of both the pump handle and the pump  
ever. Align these holes, take the “R”  
pin provided and place through the  
holes. This affixes the handle in place  
and is ready for use.  
For storage reverse process and then  
place “R” pin through the pump lever  
RMKIT to keep from losing “R” pin.  
3. Instructions for installing shoulder strap  
plastic buckle:  
Oil cap gasket before using and  
lubricate weekly so the gasket will seal  
properly and prevent chemical leaks.  
Oil check valve and keep breather  
hole clear of debris. Your failure to oil  
may cause the tank to collapse  
and crack due to vacuum created by  
pump lubricate with “3 and 1” oil.  
First put the sprayer on a hard flat  
surface, take the white plastic buckle  
and while holding the sprayer up  
slightly, place buckle under the tubular  
metal frame. Slowly push down forcing  
the frame into the buckle. Repeat the  
same procedure for other side.  
Make sure to insert the locking pin for the  
pump handle in its (only) CORRECT  
POSITION.  
Fig. 1  
The pin limits the pump stroke for  
optimum performance.  
Observe Fig. 1 exactly. (Fig. 2 and 3 spell  
trouble.)  
For best results and to maintain a good  
seal, re-grease piston sleeve periodically  
with vaseline or similar light lubricants.

rial, carefully read, understand, and follow all instructions on  
the label.  
• Do not use flammable materials in the sprayer: they can  
ignite and/or explode, causing serious injury.  
• Never use caustic or corrosive materials in the sprayer,  
which could result in damage to the unit.

HOW TO ADJUST THE NOZZLE  
Oil check valve and keep breather hole clear of debris.  
Your failure to oil may cause the tank to collapse and  
crack due to vacuum created by pump lubricate with “3  
and 1” oil.  
To adjust nozzle, tighten cap (turn clockwise) for fine atomi  
zed spray, or loosen (turn counter-clockwise) for coarser  
spray or solid stream.  
HOW TO PREPARE YOUR UNIT FOR USE  
• For best results, the sprayer should be pumped every 5  
seconds on a continuous basis. This will maintain your  
spraying pressure. If you do not pump, you will not have  
pressure to spray.  
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.

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.  
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.  
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.  
Solvent-Based : Yes  
Viscous : No  
(*) Permanent damage will occur if sprayer is not cleaned  
properly after each use with Chlorine  
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 15 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 spra  
ying pressure. If you do not pump, you will not have  
pressure to spray.
