ATV COMPATIBILITY
The Sprayrider™ Generation 2 models have been designed to fit the widest range of ATVs. At time of release
the Generation 2 models were designed to fit all available Honda, Yamaha, Suzuki, Kawasaki, Polaris and
Bombadier models available in New Zealand.
For reasons of stability it is not recommended that 80L models be fitted on the front of your ATV.
50 litre models fitted on the front of ATVs where there is a gear lever mounted on the guard , must be offset to
the left to allow the transmission lever to be placed in the park position.
SR35 is best suited for rear carrier mounting, mounting to front carriers may cause tank failure.
INSTALLATION
All Models
Unpack the sprayer and check the contents. The following parts are included (Some parts are packed inside the
tank);
Tank unit with pump and cover(no cover on SR35 units), suction valves and hoses, filter basket and lid
Auxiliary tank unit (not fitted to SR35) and delivery hose
Battery cable assembly (includes remote switch)
Vacuum release valve
Spray gun (lance and handle may be disassembled)
Ratchet tie down strap
Operators manual
CAUTION
To avoid damage do not attempt to remove the suction hoses from inside the tank.
Battery Cable
Locate the battery cable and attach it directly to the ATV battery terminals.
CAUTION
To avoid damage to Sprayrider™ accessories take care to ensure that the red wire is connected to the positive
terminal.

9
Switch Mounting
Route the cable from the battery compartment to the Sprayrider™ location taking care to avoid hot components
and places where the cable can get pinched. The wire coming out of the fuse holder should be straight. Mount
the C-Dax remote on/off switch in a convenient position onto the handlebars of the ATV. Mounting the switch on
the left hand side leaves your right hand free to operate the throttle control.
WARNING
To avoid the risk of fire, do not remove the fuse holder from the circuit or replace the fuse with one rated higher
than 15A.
Fitting the Tank
Place the tank on the carrier and ensure the base of the tank sits flat on the carrier.
CAUTION
To avoid adversely affecting the handling of the ATV do not install an 80 litre model on the front carrier.

10
Ratchet Strap
Secure the tank to the carrier frame using the ratchet strap provided. Route the strap as shown below ensuring
the strap is positioned over the “wings” of the auxiliary tank as shown, nearest to the centre of the tank as
possible. The tie-down hooks must not be located where they can rub against the tank and cause damage.
NB: Tiedown goes through the cavity at the rear of the SR35
Vacuum Release Valve
Locate the vacuum release valve and screw the valve tightly onto the fitting next to the lid of the tank.
Place both hooks at
the front.
Loop strap

frame
Tighten ratchet so
that tank sits
centrally on frame

11
Spray Gun
Locate the spray gun (HGSR) and lance inside the spray tank (Gun for SR35 will be located in the shipping
box).
For SR35 the self store hose simply needs to be pushed into the push lock fitting as per the picture below left
For the SR50 screw the lance onto the spray gun trigger handle as per above right. SR80 models have the
lance fitted to the trigger handle.
Screw the spray gun onto the hosetail connected to the spray hose, ensure it is secured tightly so that the
handle does not leak when operated (do not use thread tape as this may cause the trigger handle to split).
Secure the spray gun in the stowed position under the two lugs of the auxiliary (hose reel) tank as shown. This
method of securing the spray gun is unique to the SR50 and SR80 tanks and is designed for the HGSR spray
gun only. On SR35 units the handgun mounts are on either side of the tank
Connect the Sprayrider™ electrical connector (at front of the tank) to the battery cable.

12
THEORY OF OPERATION
Spray fluid is prepared and placed in the tank via the lid opening and strainer basket. Foreign matter is trapped
in the strainer mesh for disposal after the tank has been filled.
When the pump is switched on power is applied to the pump motor from the vehicle electrical system. When the
pump operates, fluid is drawn through the filtered valves at the base of each leg of the tank and into the pump
head via hoses inside the tank.
When one leg of the tank is empty the valve at the base of that leg will close. This will prevent air from being
drawn into the system and allow evacuation of fluid from the opposite leg. When both legs are empty, both
valves will close. With both valves closed, a vacuum is created within the system that retains the valves in the
closed position. When the tank is refilled the vacuum is released by momentarily manually opening and closing
a valve located at the top of the tank. The tank valves will reset to the open position and allow fluid to be drawn
from the tank.
OPERATING INSTRUCTIONS
Before switching on the pump, momentarily open and close the knob on the vacuum release valve located on
top of the tank next to the lid. This will allow the suction valves to reset to open. This operation will need to be
repeated each time the tank is re-filled from empty.
Switch on the pump switch mounted on the handle bar of the ATV. The pump will run for a short time then shut
off.
Operate the spray gun trigger. Fluid will be sprayed from the adjustable spray tip and the pump will operate. If
necessary adjust the spray tip to alter the spray pattern.
NOTE
If fluid does not flow when the pump is running and the spray gun trigger is operated, switch the pump off and
open the knob on the vacuum release valve for five seconds, then close.

13
Hand Washing
50L and 80L Sprayriders™ are fitted with a 2-litre fresh-water wash tank for hand washing in the field. To wash
hands pull the outlet valve to the open position, wash hands then push the valve closed.
NOTE
Hand wash tanks are not fitted to SR35 tanks and are only applicable to 50/80 litre models.
CHEMICAL APPLICATION
CAUTION
This handgun sprayer is not a high volume sprayer nor is it ultra low volume. As a general rule for most spotting
applications, label rates under the heading “knapsack rates” would apply.
As no control can be exercised over the use of the equipment or over weather, plant or soil conditions, or over
the storage, handling, mixing, use or application of sprays or chemicals, C-Dax Ltd will not accept any liability
for loss or damage (consequential or otherwise) arising directly or indirectly from the use of this equipment.
Chemical Advice
C-Dax Ltd or their agents cannot make recommendations or give advice as to the use of chemicals and cannot
accept responsibility for any damage, injury or other consequence for disregarding this warning notice. Contact
your chemical supplier for advice.
WARNING
Mixing chemicals is a most dangerous activity as it involves handling the concentrated material. For toxic
compounds, use protective clothing such as overalls, hat, gloves, boots and respirator.
When using diluted sprays, wear at least a hat, long-sleeved cotton overalls, and boots. If you use pesticides
regularly, it is a good idea to always wear a respirator to avoid accumulation of toxins in the body. Other
protection may be required. Check the label for specific directions for the particular chemical.
Purchasers must ensure that operators of these machines are fully aware of the dangers of spraying chemicals.

14
OPERATING HINTS
Spray Hose
Be careful not to wrap the hose so tight as to inhibit the flow of fluid by kinking the hose.
Length of Spray Hose
If most spraying is “from the seat”, the hose length should be shortened. Quick release hose connectors (brass)
are available from your C-Dax dealer. These will enable the operator to simply connect the longer hose when
required.
Nozzle Choice
Nozzles provided have been selected to match the performance of the pump. The adjustable nozzle gives a
cone pattern, ideal for spot spraying.
Tank Inserts
Do not over-tighten the quick release hose connector (brass) when fitting it to the tank return brass insert
(SR50/80 only). If the insert is over-strained a leak could occur. Liquid thread seal is recommended to ensure a
leak-free joint. Plastic thread tape is not recommended.
Pump
The Flojet pump features an internal bypass function and as such it needs no pressure adjustment. When the
flow is restricted and pressure builds up the pump will automatically bypass fluid.
Using the Sprayrider™ with a Spray Boom
NOTE
SR35 is a spot sprayer only and is not suitable for boom spraying
All spray booms supplied by C-Dax as 12Volt Sprayer accessories are supplied with a quick release valve to
allow convenient connection of either the spray gun or spray boom. Spray booms that require a bypass to divert
fluid back to the tank, such as the CDA booms, are supplied with a bypass fitting to screw into the rear of the
Sprayer tank.
All spray booms intended for use with the Sprayrider™ are supplied with spray tips that match the output of the
SR35/50/80 pump and will spray at approximately 2 bar (30 psi). Changing the tip size will alter the spraying
pressure.
Decreasing tip size will increase the spraying pressure. The spray tips are calibrated to 4 bar spraying pressure,
which determines the minimum tip size that can be fitted.
Increasing the tip size will decrease the spraying pressure. All spray booms sold by C-Dax for use with the
Sprayrider™ are fitted with non-drip check valves. These valves close at a pressure of 0.8 bar (10 psi). For
reliable boom operation we do not recommend spraying pressure below 1 bar (15 psi).

15
ROUTINE MAINTENANCE
Cleaning
Clean the sprayer regularly! After each use flush the unit out three times with fresh water. Use a neutralizing
agent for the second rinse.
CAUTION
To prevent damage to the sprayer and spray gun, drain the water from the sprayer and spray gun when there is
a risk of frost.
Filters
There are four filters in each Sprayrider™ fluid system. Each one must be checked and cleaned after each use.
The tank strainer basket is retained by the lid to assist cleaning. Always clean the strainer before filling the tank
with spray solution.
The C-Dax valve assembly at the base of each leg has a stainless steel mesh filter for straining the fluid before
it reaches the pump. Unscrew the cap at the base of each leg and allow the valve assembly to hang free from
the tank. This exposes the valve filter mesh for cleaning. Take care not to lose the O-ring.
Carefully rinse each stainless steel mesh with a hose.
CAUTION
To avoid damage to the filter mesh, do not attempt to remove the mesh from the valve assembly.
Do not use excessive pressure when cleaning the valve and filter mesh.
CAUTION
When refitting the valve, do not overtighten the valve nut. Tighten to hand tight only.

16
Each HGSR spray gun has a built-in filter in the spray tip. Unscrew the red spray tip holder from the lance nut to
expose the tip filter. Pull the lance nut back to reveal the filter. Rinse under a hose and replace the filter element
in the spray tip (the dished side faces toward the trigger).
Removal of the Sprayrider™
1. Unplug the switch/battery cable at the
tank connector.
2. Release the ratchet strap.
3. Lift the Sprayrider™ off the vehicle.
4. Place the tank on a suitable support so
that the legs do not have to support the
weight of the tank. The tank can be
conveniently hung on a wall using a loop
of string around the center of the tank.
Lubrication of the Spray Lance
For trouble-free operation of the spray lance it is recommended that the trigger valve be lubricated with rubber
grease (lanolin) at regular intervals. Unscrewing the black knob on the topside of the spray gun handle
accesses the trigger valve. The interval should reflect the usage of the lance.
Care of Protective Clothing
Protective clothing should be properly cared for. Rinse heavily contaminated clothes in the open before washing
in the laundry. Wash and dry these clothes every day and keep them separate from other washing.
Respirators need special care. Clean the respirator after spraying. Use soapy water then rinse and allow to dry
completely before storing in a clean plastic bag. Replace canisters in respirator after eight hours use. Never
store used canisters with the respirator.
The minimum requirements for personal safety are that the operator avoids spray inhalation and does
not allow chemicals or spray mixture to contaminate the eyes or skin.

17
Removing the Pump
CAUTION
To prevent damage to the pump and tank connector ensure the tank is upside down when removing the pump
cover. Remove the vacuum release valve first to prevent damage.
1. Remove the vacuum release valve.
2. Place the sprayer upside down.
3. Remove the six screws securing the pump cover and remove the cover (SR50/80 only)
4. Unclip the suction and delivery hose connections by pulling the blue tabs into the unlocked position.
5. Unscrew the four mounting screws hold the pump in place (SR35 only)
6. Lift out the pump.
Installing the Pump
CAUTION
To prevent leaks, never use thread tape on the suction or delivery hose connections as this may prevent proper
sealing of the cones. Do the nuts up finger tight then advance the nuts one quarter turn.
1. Place the pump in the pump cavity as shown above.
2. Connect the suction and delivery hoses.
3. Screw four mounting screws into inserts (SR35 only)
4. Replace the pump cover. (SR50/80 only)
CAUTION
Always operate the SR50/80 with the pump cover in place. The pump cover holds the pump in position

TROUBLESHOOTING
C-Dax Ltd and their distributors have a comprehensive parts inventory and capable service staff.
Repairs should only be undertaken by C-Dax, or an authorised C-Dax service center.
Symptom
Possible causes (procedure)
Probable solution
Pump does nothing
(makes no noise)
Blown fuse (check wiring for shorting
and inspect fuse)
Repair/replace faulty wiring or 15A fuse as
necessary
Loose/intermittent connection (check
all wiring and connections)
Check all wiring and connectors to ensure solid
connection
On/Off switch failed (remove switch
from handle bar, bridge the 2 spade
terminals using a screw driver)
Replace switch if using the screw driver causes
pump to work
If all above fails, likely cause is pump
failure
Take in to local dealer or send to C-Dax for repair.
Be sure to include sufficient paperwork detailing the
problem.
Pump runs for few
seconds then stops
Pump has primed and pressure
switch has activated (this is normal)
No fault, squeeze spray trigger and use as per usual
Fluid leaks from drain
holes in pump
Internal leak within pump head
Take in to local dealer or send to C-Dax for repair.
Be sure to include sufficient paperwork detailing the
problem.
Tank empties from
one leg only
One of the filter valves are not sealing
off properly (Inspect the filter valve at
the base of each leg)
1. Unscrew the nut that holds the filter valve on to the
bottom of the leg. Clean filter thoroughly but carefully
using hose.
2. Check the hose that connects to the filter valve for
splits at bottom. If split found: replace hose.
3. If all above fails, replace filter valve(s)
Tank only partially
empties
One of the internal suction hoses has
developed a leak.
Remove lid and inspect internal suction hoses. The
split/hole will be at the same level as the fluid. You
may need to detach the hoses from the black cross-
fitting at the top of the tank and extract by removing
the filter valve at the bottom of the leg (be sure to
empty tank first).
Pump runs but does
not spray (or sprays
but with little
pressure)
Air lock in pump
Operate spray gun trigger until all air is expelled from
the pump and hose (may take a few moments)
Air leak in suction line
Inspect the suction line (between the tank and pump)
for signs of split hoses and loose clamps. Replace
split hose if required and ensure all clamps are done
up tight.
Blocked suction filter valves
Inspect filter valves and clean if necessary
Air lock in suction line
Pop up the blue/white vacuum release valve on top
of the tank and press it down again (ensure this
valve is screwed on to the black fitting tightly).
Dirt or spray residue in pump valves
Replace valves inside pump
Pump fails to prime (usually on very
first use)
Remove the blue/white vacuum release valve on top
of the tank by carefully unwinding it from the black
fitting (ensure the black fitting stays attached to the
tank). Now force water (from a garden hose) down
the black fitting while the pump is running, this
should force the pump to prime. Screw the
blue/white vacuum release valve back on to the
black fitting tightly and pop the valve down. This
should prime the pump and make the sprayer
operate as per normal.
Pump sprays but does
not stop spraying
Spray gun trigger open
No fault, close trigger
