GENERAL
The Silvan Rakpak is a compact portable sprayer. Whether you are a commercial grower, or hobby
farmer, you will find many uses for this unit. The tank, pump and spray lance fittings are corrosion
resistant and suitable for applying weedicides, herbicides, insecticides, fungicides, miticides, organic
and green formulations.
It has been solely designed for mounting on four-wheel Quad Bikes. The Rakpak is designed for spot
spraying but may be used in conjunction with a boom for boom spraying.
SPECIFICATIONS
PUMP AND CONTROLS:
Pakpump 2000 series, 12-volt DC electric pump. Open flow Capacity 5.3 L/minute or Maximum
pressure 60psi.
On-Off power switch and an “on demand” pressure sensing switch.
Supplied with 3 metre power loom with alligator clamps for connection to 12-volt battery and a fuse
holder on the positive lead fitted with automotive type 10-amp fuse.
The “On-Demand” pressure sensing switch will automatically start the pump when the spray gun
trigger is pulled, and the pressure falls below 40psi. The automatic pressure switch will stop the
pump when the spray gun trigger is released, and the pressure increases to 60psi.
If the pump is subjected to rapid pulsation/cycling during normal operation it may reduce the life
of the pressure switch. Applications which exhibit rapid pulsation/cycling may have restrictions in
the nozzle caused by dirt or may require a larger nozzle to minimize pulsation.
TANK:
Translucent tank moulded from U.V. stabilized and impact resistant polyethylene.
135mm filler neck with screw on anti-spill breather lid.
Calibrated fill mark moulded into tank as well as recesses for locating tie down straps for transport.
FILTRATION:
Wire mesh foot filter on suction line, removable for cleaning.
DELIVERY HOSE:
6 metre length, 8 mm I.D.
SPRAY GUN:

Specifications

FITTING TO A VEHICLE
The sprayer should be securely attached to the Quad bike. The transverse recesses moulded into
the top of the tank can be used to positively locate the tie down straps, which should be firmly
secured to approved attachment points on the ATV or other vehicle.
The sprayer should be mounted centrally and as
near to the centre of gravity of the Quad bike as
possible. It should not protrude to cause an
obstruction. Refer to the manufacturer’s
instructions for appropriate load limits and
fitting positions.
Never fill the spray tank to a capacity beyond
the specified overall weight limit set by your
vehicle manufacturer.
Note: 1 litre of water = 1 kg.
Warning! Do not exceed the the vehicle
manufacturer’s specified safe load and carrying
capacity.
CONNECTING TO 12 VOLT DC SUPPLY
The sprayer requires a 12-volt DC power
source to operate the pump, such as the
vehicle battery. The wiring loom is fitted with
alligator clamps to facilitate connection to a
normal vehicle battery. The red clamp should
be connected to the positive terminal and the
black clamp to the negative terminal.
If you need to extend the wiring loom use wire
of the same gauge or thicker.
SAFETY FUSE
The positive (brown) lead incorporates a 10-
amp automotive type fuse in a rubberised holder. This protects the pump and vehicle electrical
system from damage should a short circuit occur. If a fuse should blow determine the cause of the
short circuit before replacing the fuse.
ON/OFF SWITCH
The on/off switch on the top of the tank operates the pump. It should be switched off when the
pump is not in use or when the tank is empty to prevent unnecessary drain of power and overheating
and damage to the pump.
CONNECT LANCE AND TRIGGER
For sprayer, there is a gasket which should fit between lance and trigger. The small side is
positioned face to trigger.

SETUP AND TESTING
It is always recommended that you first test all spray equipment thoroughly with clean water. Silvan
Rakpack’s are supplied with an adjustable nozzle containing a large orifice, 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 require.
1. Be sure to wear safety equipment as recommended by the chemical manufacturer before
adding chemical to the sprayer
2. Check the suction line foot filter is clean and undamaged (see Maintenance section).
3. Fill the tank with clean water.
4. With the 12-volt supply connected and the 6-meter spray hose and spray lance connected fit
the 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. Switch the pump ON.
7. Depress the spray lance trigger. The pump is self-priming and will start spraying within 30
seconds.
8. Check the hose connections for leaks, if any are found stop the pump and rectify the problem
before continuing.
9. By twisting the tip of the nozzle to the coarsest droplet size, the restriction to flow is minimized
and pump pulsation will not occur.
10. Slowly twist the tip of the nozzle from a course droplet size to a fine droplet to your preference.
If the pump begins to pulsate/cycle you may require a different nozzle that is rated to allow for
higher flow rates at your selected droplet size at approximately.
11. Once the nozzle is set the sprayer is ready to be utilized for spot spraying of chemical.
12. 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
PUMP HOSE ANCHOR
We have supplied a Plastic Hose Tie to protect the pump housing or hose fitting from possible
damage caused when the hose is pulled tight or over stretched.
The hose can be tied against the switch bracket as shown in the diagram below without restricting
the flow.
Operation

After spraying is completed, drain unused chemicals from the tank. Rinse the tank with clean water
then operate the sprayer with clean water in the tank to clean out the pump, hose, and spray lance.
Do not leave chemicals in the tank as they may settle and form solids that may 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.
After spraying rinse out the spray lines and tank with clean water
The foot filter should be checked and cleaned if necessary, each time the tank is filled. Appropriate
protective equipment including gloves should be used whenever maintenance is carried out.
CLEANING THE FILTER
To check the filter, remove the filler cap and hook the suction hose out with a bent piece of wire.
To avoid chemical contamination do not put bare hands in the tank to remove the filter. Appropriate
protective equipment including gloves should be used whenever maintenance is carried out. Clean
the filter with a bristle brush, do not use a wire brush or sharp object as this may damage the mesh.
The filter can be pulled from the suction hose if necessary, for cleaning. When reinstalling the filter
in the tank press the suction hose into the recess to keep the filter on the bottom of the tank so
that it will fully empty.
Operation (cont.)
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 manufacturer.
