WARNING:
Chemicals can be harmful to individuals and the environment if improperly used. In addition, some chemicals are caustic,
corrosive, or poisonous and should be avoided. Read warnings and follow chemical manufacturer's instructions. Solo
sprayers are fitted with Viton®seals, which are resistant to a wide variety of agricultural and household chemicals;
however, care should be exercised to ensure that sprayer components are clean, functioning properly, and in a good
state of repair before and during use. If in doubt about a particular chemical, check with manufacturer. If you suspect or
observe indications that the material may be unsafe in a Solo sprayer... STOP! Do not use or apply chemical!
ALWAYS WEAR RUBBER GLOVES, SAFETY GOGGLES AND APPROPRIATE PROTECTIVE CLOTHING.
Read and follow operating instructions. Test sprayer with plain water to familiarize yourself with sprayer features.
Do not fill sprayer over maximum fill mark. Releasing pressure in an overfill condition can cause harmful venting of
sprayer contents. Only release pressure by spraying chemical into a suitable container for later use.
Only relieve pressure with sprayer upright.
CAUTION: To prevent injury from ejected pump assembly and/or solution, never stand with face or body over the
top of the tank when pumping, or while loosening pump.
Do not modify sprayer.
Never spray in the direction of humans, animals or property which might be injured or damaged by spray formula.
Do not use disinfectants, solvents or impregnating agents unless first tested to ensure they are not harmful to the
environment or the sprayer.
Do not use liquids with a temperature above 110°F (43°C).
A sprayer filled with liquid is a significant amount of weight (8 lbs. per gallon). When carrying, use caution when
bending, leaning or walking. Bend only at the knees and support yourself as necessary to ensure personal safety.
Do not pressurize sprayer without liquid in the tank.
Do not climb on ladders, trees or other unsteady or potentially unsafe structures while using sprayer.

manufactured parts, which fail due to defective material or workmanship, will be repaired or replaced
without charge. See page 3 for full details.
STOP! If you are missing parts, instructions or have questions, DO NOT take this unit back to the

CAN I USE WEED KILLER, INSECTICIDES AND CLEANING COMPOUNDS IN THE SAME SPRAYER?
In theory you can, if the sprayer is thoroughly cleaned with a detergent/water solution of 1:100. In practice, the use of
both types of chemicals in the same unit is not recommended as the risk to plants, etc. can be high. Use caution when
handling any type of chemical and when cleaning your sprayer. Do not mix cleaning agents as toxic reactions can
result.
WHAT SPRAY NOZZLE SHOULD I USE?
A flat spray nozzle is supplied for spraying wide areas such as paths, garden beds, and general area spraying. A cone
nozzle is also supplied for spot spraying and for the treatment of bushes and small trees. For spot spraying, simply
remove swirl plate from behind nozzle tip. Save the swirl plate for future use. An optional reflux filter (#2700316) is
available with a built-in check valve, which opens at 5 psi and closes at 4 psi. This virtually eliminates the dripping of
fluid still contained in the spray wand. A wide selection of nozzles such as deflector, adjustable, and anti-drift nozzles
are also available.
CAN I DO SPOT SPRAYING?
The shut-off valve on the Solo sprayer is well-suited for spot spraying. It's almost effortless! The shut-off valve handle
incorporates a clip, which holds the valve open for area spraying without tiring the operator's hand.
Assembly Instructions for Wand
Ensure that the O-ring is on the non-threaded end of the wand.
Insert the non-threaded end of the wand with O-ring into the open end of the
shut-off valve.
Tighten the screw cap.
Tank is fitted with a slide-retainer for easy wand storage.
Using the Brass Adjustable Nozzle
To change the spraying pattern, first make sure the retaining nut (1) is screwed
tightly to the elbow (4). For a straight stream pattern, rotate the nozzle outward.
For a hollow cone pattern, rotate the nozzle inward towards the retaining nut. If it
becomes difficult to rotate the nozzle cap, remove the nozzle cap from the nozzle
body and lubricate the O-ring on the nozzle body with non-water soluble grease.
Solo lubricant #9850 is available. WARNING: Handling the brass parts of this
product will expose you to lead, a chemical known by the State of California to
cause birth defects and other reproductive harm and/or cancer. Wash hands after
handling.
Operation:
Before using sprayer with chemicals, fill sprayer with fresh water to assure that
you have it properly assembled; pressurize and then practice spraying. When
thoroughly familiar with sprayer operation, follow normal operating procedures.
To remove pump, release pressure, then turn pump handle counterclockwise.
Fill tank with premixed formula up to desired level. Observe recommendations
of chemical manufacturer.
Tighten pump assembly for a good seal.
Start or stop spraying by squeezing or releasing the lever on the shut-off valve.
The spray pressure can be monitored with an optional pressure gauge, part
#4900622.
Prior to removing the pump (see page 4 - #1), release pressure by spraying
