HOW TO ASSEMBLE
1. Attach spray wand to spray gun and
tighten firmly.

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.

Oil cap gasket before using and lubricate weekly so the
gasket will seal properly and prevent chemical leaks.
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.
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.
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.
