The TRAYLINK provides three ways to control output.
1. Two manual section valves one too the boomless
nozzles and the other to the spot spraying lance.
2. A proportional regulating valve with graduated dial
and pressure gauge allows adjustment of application
and tank agitation rates (Contains EPDM seals).
3. The power loom contains a small control box with
remote on/off switch and 20 amp fuse to allow pump to
stop boom-less spraying from a driver’s seat or cab.
Specifications (cont.)
Silvan TrayLink Sprayers feature a 12V 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 high
enough to automatically switch the pump completely off.
The use of the TrayLink 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 specific 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 utilize 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.
The TrayLink can be mounted to a small tractor via CAT I three point linkage points; alternatively the small tank and
frame is suitable for mounting on to the deck or tray of a vehicle with appropriate tie down straps. Refer to
manufacturer’s instructions for appropriate load limits and fitting positions.
Note: When the TrayLink is delivered with the boom-less nozzle holder disconnected from the frame to protect it
from transport damage. Before the TrayLink is mounted to a vehicle it is best that you attach the nozzle holder
bracket to the frame (as shown below). The nozzle holder bracket can be fastened by hand with a Tri-Screw to 2
positions for boom-less spraying for TPL or Tray mount.
Boomless Nozzles set at rear for
Mounting with Three point Linkage
Boomless Nozzles set at the side for
Tray Mounting
When fitting the Boomless nozzles to the frame note the orientation
of the bracket and hose. The nozzles will require aligning with in
each nozzle cap to prevent mis-spray against the frame and tank as
well as adjusting the swivelling nozzle holder which angle will effect
the swath with and spray pattern.
Note : 1 litre of water = 1 kg.
Never fill spray tank to a capacity beyond the specified overall
weight limits set by your vehicle manufacturer. When fitted these
should be firmly secured to approved attachment points.
Warning ! Do not exceed the vehicle manufacturer’s
specified safe load and carrying capacity.
The Sprayer requires a 12 volt DC power source. A power loom 5.5 metres long is provided with the sprayer to allow the
sprayer to be connected to the 12 volt DC source. One loom contains aligator clips for attaching to a battery or suitable 12V
DC power supply, the red clip is positive and the black is negative. The second loom features a water resistant electrical
connector that clips to a corresponding connector on the pump. If you extend the wire use wire of the same gauge or larger.
The power loom contains an inline control box with on/off switch to allow the sprayer to be switched off from the 12 volt
DC source to prevent accidental drain of power and to shut down the pump when the tank is empty preventing overheating
and damage to the pump. An additional benefit of switching off the pump remotely allows for the boomless nozzles to be
switched off in a situation or set up where the operator cannot safely reach the manual section valve.
A 20 amp fuse is fitted to the control box to prevent any
potential damage to the electrical system of the vehicle.
Consult your vehicle instruction manual for correct electrical
It is always recommended that you first test all spray equipment thoroughly with clean water.
The Traylink is supplied with both a Spray gun for spot spraying and boom-less spray nozzles with holder.
For this set up ensure that the manual section valve to the boom-less nozzles is closed and the section valve to the spray gun
is open. The supplied SpotJet Spray Gun contains a large orifice blue adjustable nozzle, which when twisting the tip can
allow for a greater flow of liquid. It is recommended that adjustable nozzle is used first and can be changed later if you
1. Be sure to wear safety equipment as recommended by the chemical manufacturer before adding chemical to the sprayer
2. Check the filter is clean and undamaged (see Maintenance section).
3. Fill the tank with clean water.
4. Ensure the 6 meter spray hose and spray lance is connected. Fit the blue adjustable nozzle or any large orifice nozzle
you may wish to use).
5. Check all pipes, hoses, hose clamps and connections for leaks or damage.
6. Check the hose connections for leaks if any are found stop the pump and rectify the problem before continuing.
7. Twist the tip of the nozzle to the coarsest droplet size so that restriction to flow is minimized.
8. Turn the regulator control knob anticlockwise (this opens the variable orifice and allows for maximum bypass of fluid).
9. Switch the pump ON.
10. The pump is self priming and should start spraying within 30 seconds. Depress the spray lance trigger to flush air from
the lines. Note: The initial pressure to the spray lance will be low
11. Slowly turn the control knob clockwise (this reduces the bypass orifice size) and increasing pressure to the nozzles until
you reach your selected spray pressure or until the pump begins to pulsate/cycle on and off.
12. Slowly twist the tip of the nozzle from a course droplet size to a fine droplet to your preference or until the pump
begins to pulsate/cycle on and off. Note: Some fine tune adjusting may be required between the nozzle and regulator to
acquire a suitable pressure and droplet size for your application.
13. If the pump begins to cycling on/off you may require a different nozzle that is rated to allow for higher flow rates at
your selected droplet size
14. Once the nozzle is set and the pump operates free of pulsation/cycling, the spot sprayer is ready to be utilized for spot
spraying of chemical.
For this set up ensure that the manual section valves to the boom-less nozzles to the spray gut are closed.
1. Be sure to wear safety equipment as recommended by the chemical manufacturer before adding chemical to the sprayer
2. Check the filter is clean and undamaged (see Maintenance section).
3. Fill the tank with clean water.
4. Check all pipes, hoses, hose clamps and connections for leaks or damage.
5. Check the hose connections for leaks if any are found stop the pump and rectify the problem before continuing.
6. Turn the regulator control knob anticlockwise (this opens the variable orifice and allows for maximum bypass of fluid).
7. Switch the pump ON.
8. The pump is self priming and fluid will quickly start bypassing back into the tank for agitation
9. Open the section valve to the boom-less spray nozzles. Spraying will quickly commence.
10. Slowly turn the control knob clockwise (this reduces the bypass orifice size) and increasing pressure to the nozzles until
you reach your selected spray pressure or until the pump begins to pulsate/cycle on and off.
11. If required you can also adjust the angle of the boom-less nozzles to add additional control over swath width. (Note:
positioning the nozzles at extreme angles may over or under extend the sprayed area resulting in uneven spray patterns.
Warning: Spray units must not be operated while the pump is pulsating/cycling because it can cause premature
component failure.
Chemical solution may now be added to the tank.
Follow the mixing instructions and safety precautions provided by the chemical manufacturer. Before adding concentrated
chemicals, partially fill the tank with water then add the chemical and complete filling with water.
Wear all the safety equipment recommended by the chemical manufacturer before adding chemical to the sprayer and
whilst conducting spraying operations.
Operation (cont.)
The Spray Gun has an additional safety feature; the lever catch can be used to lock the lever closed to prevent accidental
spraying. The catch can also be used to lock the lever open for continuous spraying. This should only be done when safe to
operate in this manner and where there is no likelihood of inadvertently spraying any person or property that may suffer

crystallize or form solids in the pump, spray lines and block the filter.
If heavy frosts are experienced, run the sprayer until the pump and spray lines are dry. This will prevent water freezing in
the pump or spray lines and damaging the sprayer.
Warning ! Dispose of unused chemical and water used for rinsing in a manner that will not endanger people, animals or
the environment in accordance with local regulations and the handling and disposal information available from
the Chemical
To avoid chemical contamination wear appropriate protective equipment including gloves whenever maintenance is carried
out; turn off the pump and depress the trigger on the spray lance to dissipate any pressure.
The TrayLink features two filter/strainers that require cleaning. Beneath the lid of the tank is a basket strainer for stopping
coarse debris from entering the tank and mounted next to the pump is an inline filter. Remove the filters to clean them,
unscrew the lid to lift out the basket strainer and unscrew the filter housing and remove the element, clean both with clean
water and a bristle-brush, do not use a wire brush or sharp object as this may damage the mesh.

Results will be best when wind speed is low, temperature low and relative humidity high. An ideal time is at sun up when
these conditions are most likely to apply.
The application rate depends on the following.
 Speed of travel - increasing speed reduces application rate and vice versa.
 Operating pressure - increasing pressure increases the application rate and reducing pressure decreases the rate.
 Nozzle size - increasing the nozzle size increases the application rate.
