6. Pre-operation
Hose clamps are not completely tight.
Please tighten hose clamps prior to using.
Hose clamps are left loose to extend life of gaskets and
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.
Before using, oil cap gasket, felt pump washer, and check
valve, and keep breather hole clear of debris. Your failure to
oil, clean check valve, and keep 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.
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 11 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
spraying pressure. If you do not pump, you will not have
pressure to spray.

7. Operation

• Always release pressure in the pump prior to filling, cleaning,
or servicing the sprayer.
• Before opening a container of pesticide or other spray
material, 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.
• To adjust nozzle, tighten cap (turn clockwise) for fine
atomized spray, or loosen (turn counter-clockwise) for
coarser spray or solid stream.
• Normal working pressure should be from 25 psi to 40 psi.
Too much pressure will waist chemical and over apply, as
well as causing potential damage to pump tube.
• Pump occasionally to maintain the desired spraying
