SAFETY PRECAUTIONS
GOLDLINE SPRAYERS
AN IMPORTANT MESSAGE FOR OWNERS & OPERATORS OF
C-Dax ATTACHMENTS/ACCESSORIES
Be warned of the dangers of loading your vehicle in excess of its carrying capacity.
It is important to understand that any loads or attachments whether fastened to or placed on a vehicle will
alter the stability or handling characteristics of that vehicle.
Spray tanks or other equipment must be filled only to a level where the gross weight is within the load limit of
the vehicle.
Safety is a primary concern in the design, manufacture, sale, and use of spray tanks and other equipment.
As manufacturers of spray tanks and other equipment we want to confirm to you, our customers, our concern
for safety. We take this opportunity to remind you about the simple, basic and common sense rules of safety
when using spray tanks and other equipment. Failure to follow these rules can result in severe injury or death
to operators and bystanders.
It is essential that everyone involved in the assembly, operation, transport, maintenance and storage of this
equipment be aware, concerned, prudent and properly trained in safety.
This also applies to equipment that is loaned or rented to someone who has not read the owner’s manual
and is not familiar with the operation of application equipment.
•NEVER EXCEED THE LOAD LIMIT CAPACITY OF THE TRACTOR OR OTHER VEHICLE.
•ALL TRACTOR AND TRAILED EQUIPMENT TYRES SHOULD BE INFLATED TO
MANUFACTURERS RECOMMENDED OPERATING PRESSURES.
•PLEASE NOTE THAT FILLING THE SPRAY TANK OR OTHER EQUIPMENT COMPLETELY AND
OR THE ATTACHMENT OF ADDITIONAL EQUIPMENT TO THE TRACTOR MAY EXCEED THE
TRACTOR’S MAXIMUM LOAD CAPACITY AND IT IS NOT RECOMMENDED TO EXCEED
MANUFACTURERS GUIDELINES
•CARGO SHOULD BE PROPERLY DISTRIBUTED AND SECURELY ATTACHED.
•REDUCE SPEED WHEN CARRYING CARGO OR PULLING A TRAILER OR TRAILED
APPLICATION EQUIPMENT AND ALLOW GREATER DISTANCE FOR BRAKING.
•NEVER ALLOW ANYONE TO RIDE ON YOUR SPRAYER OR OTHER EQUIPMENT.
•ALWAYS FOLLOW THE INSTRUCTIONS IN THE OWNER’S VEHICLE MANUAL FOR CARRYING
CARGO OR PULLING A TRAILER.
•PROPER MAINTENANCE IN LINE WITH MANUFACTURER’S RECOMMENDED MAINTENANCE
PROCEDURES IS ESSENTIAL.
•BEFORE APPLYING CHEMICALS, READ THE LABEL OF THE CHEMICAL MANUFACTURER OR
SUPPLIER FOR PERSONAL PROTECTIVE EQUIPMENT AND OPERATE AS RECOMMENDED.
THE SAFETY OF ALL CHEMICALS USED IN AGRICULTURE IS UNDER THE JURISDICTION OF A
GOVERNMENT AGENCY, IE N.Z. MINISTRY FOR THE ENVIRONMENT; USA ENVIRONMENTAL
PROTECTION AGENCY. FURTHER LOCAL GOVERNMENT OR STATE LAWS MAY APPLY.
WARNING
To reduce the chance of VEHICLE instability, it is recommended to exercise EXTREME care while
spraying on a slope or hillside.
WARNINGS, CAUTIONS & NOTES
Throughout this document, text has been highlighted as warnings, cautions and notes.
Warnings are mandatory instructions. Failure to comply with these instructions may result in injury or damage.
Cautions are advisory. Failure to comply may result in poor operation or premature failure.
Notes are to assist with convenient operation of the equipment.

3
SAFETY
Before attempting to install or operate the equipment, read and understand the manual thoroughly. Failure to
comply with this instruction constitutes improper use and will invalidate the warranty.
Before using your pesticide, STOP, Read The Label
Mixing pesticides is a most dangerous time as it involves handling the concentrated material. For toxic
compounds, use protective clothing such as overalls, hat, gloves, boots and respirator.
When using concentrated sprays, full protection is necessary.
When using diluted sprays, wear 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 cumulative effect.
Other protection may be required. Check the label. It may have specific directions for the particular chemical.
Protective clothing should be properly cared for. Rinse heavily contaminated clothes in the open before washing
in the laundry.
Wash and dry protective clothing every day, but keep them separate from other washing.
Respirators need special care. Clean your respirator after spraying. Use soapy water then rinse and allow drying
completely before storing in a clean plastic bag. Replace canisters in respirator after eight hours use.
WARNING/CAUTION
PTO shaft length may be need to be trimmed depending on tractor.
The shaft length should be determined with the linkages adjusted appropriately
for the sprayer/spreader (i.e. level).
Read PTO Shaft instructions (attached to shaft) before fitting/operating unit,
failure to do so could cause damage to the unit attached.
Always exercise caution when working around PTO shafts. Never work in the
vicinity of a PTO shaft that has its drive engaged.

THEORY OF OPERATION
Spray fluid is placed in the tank where it is drawn through a suction filter and pumped to a control valve. The
excess flow from the valve is returned to the tank via the bypass hose. Fluid at a nominal pressure is pumped to
the spray outlet via the spray hose.
If a boom is fitted, when the pressure in the spray lines reaches 0.7 Bar (10 psi), the diaphragm check valves at
each nozzle body open allowing fluid to reach the spray tips.
If a hose reel is fitted fluid will pressurise the reel until the spray gun is operated.
The control unit has a pressure adjustment valve to regulate the spraying pressure with a maximum pressure
relief valve.
When the dump valve on the control unit is operated, the pump output is allowed to return to the tank with
reduced restriction. The resulting drop in pressure allows the DCVs in the boom to close and spraying will stop.
The CD7C compensating control unit also has individually adjustable metered bypass outlets fitted to each
controller outlet to return the unused flow from each valve. This allows the operator to turn individual boom
sections on or off without affecting the spraying pressure.
The CD7V Volumetric control unit also has a pressure regulating proportional flow control valve, and individually
adjustable metered bypass outlets fitted to each controller outlet. This allows the operator to vary speed within the
pressure range and maintain a set flow to the spray boom as well as being able to turn individual boom sections
on or off without affecting the spraying pressure.
At the spray tip, fluid is atomized at the spraying pressure and the fluid is propelled toward the target at the tip
angle (80or 110nominally).
The spraying pressure controls droplet size.
Application rate is controlled by tip size, and vehicle speed.
CALIBRATING YOUR PRESSURE NOZZLE BOOM KIT
Metric Version (litres, metres, kph)
(*Standard nozzle spacing 0.5 metres)
You will need to calibrate your sprayer to ensure the accurate application of chemical or liquid fertilizer. If too
much chemical or liquid fertilizer is applied you will be wasting money! If too little is applied you may need to
repeat the spraying, which will be wasting your money and time!
Chemicals are expensive. Repeat calibration frequently during the seasons to avoid disappointment.
To calibrate your sprayer you will need:
a) Nozzle calibrator or an accurate measuring flask
b) Watch or clock with seconds, or a stopwatch
c) Tape-measure
d) Calculator
NOTE: “Chemical “ also refers to liquid fertilizers.
1. Measure time taken to travel 100m at the speed used for spraying
NOTE
Maximum Recommended Spraying Speed is 12 Kph.
2. Run Sprayer and record output from each nozzle (in mls) for the same time it took to travel 100m.
Calculate average flow per nozzle.
I.e. Add individual nozzle output and divide by number of nozzles.
NOTE
Check any nozzle tip that is out by ± 5%
Discard any nozzle tip that is out by ± 10%
3. Litres/ha = Average Nozzle output (ml/nozzle) x 100
500 nozzle spacing mm)
4. Chemical to add to tank
Litres of Chemical = Water in Tank (L) x Label chemical rate/ha
L/ha (application Rate)

10
HINT: If you want to spray one hectare, but a tank load covers two, then simply put in half the amount of
chemical and water in the tank. Similarly if you want to spray half a hectare and a tank load covers two, then
quarter the amount of chemical and water in the tank, and so on.
Select Tip Size
There are several size tips available depending on the type of spray pattern required and the amount of spray
fluid required to be applied. All spray tips supplied by C-Dax LTD conform to an international standard for tip size
and colour coding. Use the spray tip chart below to select the required tip size for your application:

OPERATION
Hand Gun Spraying
- Add chemical mix into the tank at handgun spraying rates recommended on chemical container
- Ensure control unit pressure control knob is wound fully out (CCW) and dump valve set to 0 (dump
position)
- Run pump at 540 rpm
- Ensure fluid flows in return line to tank
- Turn dump valve lever on control unit to I (pressure position)
- Set Control unit pressure to required handgun setting.
WARNING
To prevent damage to pump and control unit, do not exceed recommended maximum rated pressure on the
spraying components.
-Open valve to hand gun, and allow fluid to flow until all air is expelled from spray line
- When spraying has finished, turn dump valve lever on control unit to 0 (dump position), and control unit
pressure control is wound fully out (CCW)
- Proceed with rinsing procedures
WARNING
To prevent premature failure of drive shaft, DO NOT use drive shaft for heavy-duty equipment. Drive Shaft is
rated 16hp only (conforming to ISO 5674).
WARNING
To prevent premature failure of driveshaft, DO NOT exceed 15angle above or below horizontal on drive shaft
during operation.
WARNING
To prevent premature failure of spray pump diaphragms, pump speed MUST BE set at 550 RPM during
operation.
NOTE
If you are using a Geoline Electric control unit, ensure all compensating valves are closed during handgun
operation. Take note of each valve’s position and return them to this position once hand gun spraying is
complete.
To prevent premature failure of spray pump diaphragms, pump speed MUST BE set at 550 RPM during
operation.
Boom Spraying
- Add chemical mix into the tank at pressure nozzle spraying rates recommended on chemical container
- Ensure control unit pressure control knob is wound fully out (CCW) and dump valve set to 0 (dump
position)
- Run pump at 540 rpm
- Ensure fluid flows in return line to tank
- Turn dump valve lever on control unit to I (pressure position)
- Set Control unit pressure to required pressure setting (nominally 1-4 Bar (15-60psi)).
WARNING
To prevent damage to pump and control unit, do not exceed recommended maximum rated pressure on the
spraying components.
CAUTION
To allow the spraying system to operate effectively, any spraying device should not exceed 2/3 of the maximum
flow of the spray pump.
Example: 2.5 L/min x 12 nozzles = 30 L/min. 30 litres is more than 2/3 the capacity of the M35 pump so an
M50 would be required, or the nozzle flow reduced.
-Open valve/s to boom, and allow fluid to flow until all air is expelled from spray lines
- When spraying has finished, turn dump valve lever on control unit to 0 (dump position), and control unit
pressure control is wound fully out (CCW)
- Proceed with rinsing procedures

To prevent premature failure of spray pump diaphragms, pump speed MUST BE set at 550 RPM during
operation.
Step
GoldLine 1000L models are fitted with a folding step as standard for access to lid and lid filter; this is also an
option for the 800L model.
To use the step, release the catch holding the step to the frame and lower down.
Fold down the footplate to provide an operating surface.
To fold away after use, raise the footplate and lift the step frame up until the catch locates into the hole in the side
of the footplate. Lock the catch closed by turning back against tank frame.

Filter
600, 800, & 1000L Models
The 600, 800, & 1000L Goldline models have a suction filter with built in isolation valve.
To isolate the filter for cleaning, push and turn the yellow handle 90on the base of the filter bowl to withdraw
valve to shut off tank flow and then remove filter bowl and element.
When filter bowl and element has been replaced, tighten bowl nut and refit shutoff valve to filter, push in and turn
90to lock in place.
MAINTENANCE
After Use
oAt the end of spraying, flush the system (using the tank rinsing system if fitted) three times with fresh
water. Finish with a final rinse using C-Dax Neutralise rinsing solution. Include the spraying device/s in
this operation.
oDrain tank using remote drain bung.
oRemove the strainer basket under the lid of the sprayer, rinse and refit.
oIsolate filter using gate valve or filter isolation bung.
oRemove the main filter element, clean and refit, ensuring that the filter bowl O-ring is in place, and the
bowl nut is tight. Replace element if damaged or unable to be cleaned.
oClean the outside of the sprayer to remove any spray residue.
oLubricate the control unit levers
oRemove and clean spray tips and nozzle filters on spray boom (if fitted).
oFully extend the extension legs after use to maintain stability.
Routinely
oCheck calibration of sprayer and boom (if fitted).
oLubricate any moving boom or accessory parts.
oLubricate drive shaft.
oCheck spray hoses for kinks or damage, replace if necessary.
oCheck pump accumulator pressure
oCheck the oil level and condition in the spray pump.
Annually or End of Season
oReplace oil in spray pump (or after 200 hours, which ever comes first). Use SAE 30 antifoam oil
oReplace nozzles on spray boom
oFlush tank sprayer completely. Only water to be left in the system.

WARNING
To prevent premature failure of spray pump, DO NOT leave water in the sprayer tank or pump when there is a
risk of frost.
oRemove filters and check. Reassemble filters.
oClean sprayer thoroughly and carefully. Apply CRC to all electrical connections.
oCheck pump for leaks and poor performance. If pump requires service have it done immediately. Any
delay may result in very costly repairs.
oUnscrew regulator pressure adjustment stem 5 to 10 turns.
oRemove all Booms and inspect check-valve diaphragms. Reassemble check-valve with collar –loosely
attached.
oOil boom hinges on Agriboom, Superline and GoldLine booms, and grease indexing plates.
oCheck hosing and wiring for kinks, cuts and chafing.
TROUBLE SHOOTING
PTO Driven Spray Units Pump Trouble Shooting
- If pressure has to be regularly adjusted, check for air leaks in suction lines (Filters without “o-ring etc).
DON’T FORGET TO ADJUST PRESSURE DOWN WHEN NEXT FILLING OR PUMP WILL BE
DAMAGED.
- Pump does not Prime –Check that the suction hose packing is in good condition, that there is no air
leaks in the suction hose and that the suction filter is not clogged.
- Irregular running of the pump –Clean valves of foreign particles and if necessary replace worn or
damaged valves.
- Pump runs but lacks pressure –This depends on the regulating valve sealing or from the obstruction of
the delivery valve by foreign particles or wear. Replace the regulating valve and clean and if necessary
replace the delivery valve.
- Irregular delivery of water –(vibration of delivery pipe and pressure gauge) –check the seal on the
suction hose and that the pressure of the air in the accumulator reaches the advised figure.
- Pump level leaks oil - Oil level too high. The leakage of oil mixed with water (whitish or thick) means the
breakage of a diaphragm. In this case, stop the pump immediately, empty and drain it completely, wash
inside with diesel oil to prevent oxidation of internal parts and replace diaphragm. After this operation it is
necessary to expel the air bubbles formed between the piston and the diaphragm.
Pump Features Imovilli M50
Points to note:
Accumulator Diaphragm
- Under the Red Dome
- Pressure = 40% operating pressure
- Evens out pulsing of pump outlet
End Diaphragms
- Bolts MUST BE KEPT TIGHT to prevent cracking of the housing. If they keep coming loose, check PTO
shaft balance.
- Diaphragm is fitted edge in and writing out. Cylinder heads must be tight.
- If fluid is outside the diaphragm the damage is probably a mechanical problem e.g. PTO speed too low or
failed or worn pistons rings (located under sleeve under end plate diaphragm).
- Hydraulic diaphragm pump –There is no contact between piston and diaphragm because cavity fills with
oil.
Cylinder Head (End Plate)
- Suction diaphragm reduces “hammering” in pump.
- Pump contains four valves (two each side)
- Valves on PTO side are inlet (cap uppermost)
- Valves on pressure side are outlet (spring uppermost)
- Valve housings have “O”-rings
- Check for wear on stainless steel surfaces
- Check for wear on springs
- If either worn, replace valve assembly

Simple Rules for Dismantling and Re-Assembling Imovilli Pumps
Point 1
Before completely dismantling the pump, check that the causes for irregular running or non-function are not
amongst those indicated in the maintenance and instructions booklet supplied with each pump.
Point 2
To substitute diaphragms or internal moving parts, dismantle in the following order:
A) Suction manifold(s) (according to the type of pump)
B) Heads
C) Diaphragms
D) Cylinders
E) Pump shaft and then all the moving parts
The exploded drawing in the instructions booklet and spare parts catalogue should be of assistance.
Point 3
Carefully wash all the components with diesel oil, blow clean with compressed air, and then inspect all the parts:
Diaphragms
By inspecting the diaphragm damage one can determine the type of problem.
If the diaphragm has a cut (on the oil side) of the same diameter as the piston, the pump has been running at a
speed of less than 250-300 rpm.
Whenever there is a diaphragm failure on the oil side, with a circular rupture corresponding to the size of the
piston, one should always check that the piston/cylinder are not scored or worn. Otherwise, if this is the case, the
new diaphragms would have a very short life since the oil will not remain between the piston and diaphragm and
the latter will work only mechanically (without hydraulic support).
If there is a circular or semi-circular cut on the centre/outside of the diaphragm on the liquid side, the pump has
worked under a vacuum due to: Blocked suction Equipment, - “soft “ suction tubes which flatten during operation,
- under dimensioned filter equipment, or a dirty filter.
All these result in too much oil gathering between the piston and the diaphragm, which causes the diaphragm to
literally burst.
Diaphragms can be damaged also if the client will not release pressure when stopping/starting the pump.
N.B. The use of particularly corrosive or concentrated products can also alter the diaphragm structure causing
swelling of the part in contact with the liquid and increasing the likelihood of failure.
Cylinders
These should have no lines from the oil supply holes outwards (flange). If they do they should be replaced.
Connecting Rods
There should be no excessive play between connecting rods/bearings and the connecting rods and their coupling
rings. To check this, position shaft in a vice and mount bearings, connecting rods and rings. The play should not
exceed 0,2-0,3mm.
Crank Shaft
The shaft should have no lines or wear on the part where the connecting rods work.
Shaft Seal Bearings
Premature and repeated impute shaft oil seal failure. If the seat and the shaft are not scored or worn and
tolerances are ok (if not pump will leak also when sitting) the only reason beside normal wear of the seal
(increased in dusty conditions) can be damage on the seal itself when placed into position. The keyway has very
sharp edges and much attention should be given to this operation. It is always advisable to protect the seal with a
thin pipe.
Bearings
The bearings should be rust-free and have no excessive play. Check that the rollers and balls in the bearings are
in perfect condition.

16
Pistons
Replace the piston skirt if it is lined, especially on a low-pressure pump, which has no piston rings. Check that
play on the piston pins is not excessive.
Piston Rings
On the pumps equipped with these rings check that they have no marks or breakages. If necessary, replace.
Check Valves
Carefully check the cage. If cracked or very worn on the fins, replace. The seats are suitable, even if worn,
provided that the working surface (where the cap beats) has no cuts or deformations. The same applies to the
valves. The springs should not be worn. It is preferable to change the whole valve assembly.
N.B. Excessive wear on the check valves on a pump which has only worked a few hours could be caused by
the pump running at a higher speed than the maximum allowed (550 rpm) or by the presence of sand or
other abrasive substances in the liquid pumped.
Pressure Accumulator
It is always advisable to check the wear on the lower accumulator diaphragm and replace it if necessary. Inflate
according to the working pressure as specified below:
Pump Pressure (bar) Air Pressure (bar)
0 –5 0 –2
5 –15 2 –6
15 –20 6 –8
When dismantling a pump, which has been working, it is advisable to replace the O-rings gaskets and seals in
general to avoid the risk of having to check everything again.
Point 4
To reassemble proceed as when dismantling but in reverse, bearing in mind the following:
A) All the shoulder rings should be mounted with the bevel in correspondence with the shaft shoulder.
B) On pumps with piston rings, these should be positioned on the piston with the gaskets diametrically
opposite
C) The cylinders should be re-mounted with at least 4 oil supply holes in the direction of the shaft rotation to
assist air drainage, checking that the piston ring joints are not on line with the cylinder holes.
D) The check valve must be positioned correctly. Looking at the suction manifold can help. The valve near
the suction manifold must allow the liquid to enter the head; consequently the delivery valves should be
mounted the other way up.
NOTE
If all valves are mounted (by mistake) in the suction direction the pump will explode on starting. If mounted in
the delivery direction, the pump will not be able to suck.
E) Before re-mounting the heads, make sure that the moving parts turn freely. If they are stiff or tight, check
the assembly of the moving parts to ensure that this has been carried out correctly. One can then
proceed with assembling the heads.
F) It is a good idea to remember that a plastic hammer can be useful in both dismantling and re-assembling
the pump, but is should always be used with care.
G) After Completing assembly, fill with oil to the maximum tank capacity.
DO NOT REPLACE STOPPER.
H) Expel Air as follows:
Turn the pump shaft slowly by hand keeping it inclined with respect to the transversal shaft. Bubbles of air
will rise to the surface in the oil tank and the level will fall. Keep the oil level topped up so that air does not
enter the pump. Continue for a few minutes until no more air bubbles are expelled from the tank. Top up
the oil level to between ¼ and ¾ of the sight glass, then replace the oil stopper.
I) To eliminate any further air trapped between the piston and the diaphragm, loosen the oil tank stopper,
run the pump at 200-300 rpm for a few minutes without pressure. Check the oil level again and after
screwing the stopper shut the pump can work normally.

CAUTION
To allow the spraying system to operate effectively, any spraying device should not exceed 2/3 of the maximum
flow of the spray pump.
Example: 2.5 L/min x 12 nozzles = 30 L/min. 30 litres is more than 2/3 the capacity of the M35 pump so an
M50 would be required, or the nozzle flow reduced.
