PREVENTIVE MAINTENANCE
FIG. 5
1. Suction Line Valve (open) 2. Suction Strainer
IMPORTANT: Do not operate the pump dry! Be
certain Suction Line Valve is opened when
spraying is resumed. Damage to Spray Pump
will result when operating the Sprayer with
Valve closed.
Preventative maintenance is most important to
assure long life of the Manual Spray System. The
following maintenance procedures should be
followed on a regular basis:
Flush the entire spraying system after each use as
described above. Failure to clean the system can
result in a chemical residue which can plug the
Control Valve, Hoses and/or Nozzle Tips, and
seriously damage the Centrifugal Pump.
Wash spray nozzles thoroughly with water. 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 bowl and clean the strainer
screen when spraying wettable powders - after
every 50 hours when using liquid chemical.
A minimum of three (3) 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 an addition, if
required, are included on the chemical container.
Cleaning of 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 systems.
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.
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 for the most common causes for faulty pump
performance is gumming or corrosion inside the
pump. Flush the pump and entire system with a
solution that will chemically neutralize the liquid
pumped. Mix according to the manufacturers
directions. This will dissolve most residue
remaining in the pump, leaving the inside of the
pump clean for the next use.
Watch for plugged Nozzles. Replace all worn
Nozzles or those producing streaky or uneven
patterns.
Stop the spray flow before stopping the
vehicle.
