SAFETY PRECAUTIONS:
Do not exceed 45 psi pressure.
Do not fill with, use or spray flammable materials.
Do not use gasoline, acid, caustic or potentially injurious chemicals.
At the time of manufacture of this sprayer, we are not aware of any approved plant protection chemicals which
would adversely affect this sprayer when applied in their usual concentration.
Observe the recommendations of the chemical manufacturer.
Prior to removing any part of the sprayer pull the pressure relief valve to release any pressure in the tank.
Wear rubber gloves, safety goggles and appropriate protective clothing.
After pumping be sure handle is in the locked down position.
Individuals should be trained in the proper use of this sprayer. Where training is not available, individuals
should study and follow the procedures detailed in this manual.
Do not use acetone based chemicals.
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 chemical manufacturer’s instructions. Solo high density polyethylene sprayers
are fitted with Viton
®
seals which are resistant to a wide variety of agricultural, industrial 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.
Do not fill sprayer over maximum fill mark. Releasing pressure in an overfill condition can cause harmful venting of sprayer contents.
Relieve pressure only with sprayer upright and while standing on the side of the sprayer opposite the pressure relief valve. Venting
of sprayer contents can occur if liquid is over bottom of relief valve.
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 loosening pump.
Do not modify sprayer or pressure relief valve.
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 and sprayer.
Do not use liquids with a temperature above 120°F (45°C).
Remember that a sprayer with liquid is a significant amount of weight (8 lbs. per
gallon). Use caution when bending, leaning or walking. Bend only at the knees and
support yourself as required to ensure personal safety.
Do not inflate sprayer without liquid in the tank.
Do not climb on ladders, trees or other unsteady or potentially unsafe structures.
