GENERAL:
The Silvan Lightfoot sprayers are towable
sprayers that have been designed for the
application of agricultural chemicals to plants and
may be used with a handgun or in conjunction
with a boom.

IMPORTANT INFORMATION ABOUT 12 VOLT SPRAYERS:
Silvan Lightfoot 12V Sprayers feature a positive displacement diaphragm pump with a pressure sensing switch.
Restriction to the flow from the pump results in the increase in system pressure, which if great enough will
cause the pressure switch to cut the power to the motor. When using the 12-volt spray unit in spot spraying
applications the pressure switch can act to function as an automatic on demand switch, stopping the pump
when the spray lance trigger is released. When the spray lance trigger is depressed fluid is released and the
pressure will drop allowing the pressure switch to resume power to the pumps motor. When a pressure
regulator has been installed the pumps electric pressure sensing switch will not act as an On-Demand switch
because of pump flow bypassing back into the tank will can stop pressure from building to high enough to
automatically switch the pump off.
The use of a Lightfoot for the application of chemical requires initial set up before operation to ensure the
users personal safety, an even spray pattern and long life of the pump. Depending on your spraying
requirements you may need to change or adjust the nozzle(s) to suit your desired droplet size or spray
pressure.
When the flow rate through the spray lance or boom is very low, the pump may re-pressurize the outlet faster
than the fluid is being released causing rapid pulsation/cycling (pump switching ON/OFF within 1 seconds).
If the pump is subjected to rapid pulsation/cycling during normal operation, or for infrequent periods may
reduce the life of the pump.
Applications which exhibit rapid pulsation/cycling should have restrictions in the
nozzle minimized by fitting a larger (less restrictive nozzle) Pulsation can cause premature failure of the
pressure switch or pump; these failures are not as a result of the workmanship of the component. An
alternative to changing the nozzle to stop pulsation is to install a pressure regulator to manage flow and
pressure.
It is therefore highly recommended that the user performs the appropriate set-up to facilitate in trouble free
usage.
