Preventive maintenance is most important to
assure long life of the Spray System. The following
maintenance procedures should be followed on
a regular basis:
Flush the entire spraying system after each use.
Failure to clean the system can result in a chemical
residue which can plug the Hoses and/or Nozzle
Tips, Solenoids, and seriously damage the
Centrifugal Pump.
Wash spray nozzles thoroughly with water. Using
compressed air, blow out orifice, clean and dry. If
orifice remains clogged, clean it with a soft bristled
brush. Never use a metal object.
Check all of the nozzles frequently to spot any
inconsistencies in the spray pattern. Worn nozzle
orifices which allow a greater volume of spray
material to flow through the nozzle can cause an
expensive loss in chemical and/or turf damage.
SUCTION STRAINER: Turn off Suction Line Valve
if Tank is full of spray solution. Remove the strainer
bowl and clean the strainer screen daily when
spraying wettable powders - after every 50 hours
when using liquid chemical.
IMPORTANT: Do not operate the Pump dry! Be
certain Suction Line Valve is opened when
spraying is resumed. Damage to Spray Pump
can result when operating the Sprayer with
Valve closed.
OPERATION
PREVENTIVE MAINTENANCE
AFTER SPRAYING:
It is extremely important to carefully wash and
clean the Tank after every use. Not only the Tank,
but the Pump, Hoses, Nozzles, Screens, Filters,
and the exterior of the Sprayer also should be
cleaned.
Flush Pump After Use
One of the most common causes for faulty pump
performance is "gumming" or corrosion inside the
pump. Flush the Pump and entire system with a
Tank cleaning agent. Mix according to the
manufacturer's directions. This will dissolve most
residue remaining in the pump, leaving the inside
of the pump clean for the next use.
A minimum of three 50 gallon rinses usually is
required for all components of the Sprayer. The
addition of a detergent cleaner may be advisable
in the initial washing. Directions for such and
addition, if required, are included on the chemical
container.
Cleaning of the Sprayer should be accomplished
in an area where there is no potential for the
chemicals to be washed off in surface water or to
enter subsurface drainage system.
When Sprayer is not to be used for an extended
period, refer to the STORAGE section of this
Manual for the detailed instructions to prevent
damage to the components.
