Attaching to the Tractor

Suntuff 200 litre sprayers are equipped to fit

tractors with Category I linkage systems only.

Units of 400 and 500 litre capacity are equipped

to fit tractors with either Category I or II linkage

systems. The inner end of each lower linkage pin

is Category I diameter and the outer end is

Category II. The lower holes in the top

connection plates are Category I diameter and

the upper holes are Category II. For best stability

install the lower linkage pin with the end which is

to be used to the outside.

Remove the PTO shaft from the sprayer by

depressing the locking pin. Lower the tractor

linkage and attach to the sprayer’s lower hitch

pins of the appropriate category, then connect

the upper linkage arm using the tractor’s link pin.

Secure all link pins with the tractor’s Linch pins.

Raise the tractor linkage to the desired spraying

height and level the sprayer by adjusting the

length of the top linkage arm.

Clean and grease the splines on the tractor and

sprayer PTO stub shafts and install the PTO

shaft making sure that the spring loaded locking

pins engage in the grooves of both stub shafts.

Ensure that the tractor’s PTO shaft guard is

attached to the tractor.

PTO Shaft Length

Note: Upon delivery of a new sprayer it is the

selling dealer’s responsibility to install and set the

PTO shaft to the correct length. The following

information is provided for reference.

Set the linkage height so the ends of the two

drive shafts are at their closest. Install the PTO

shaft making sure there is at least 25mm of

telescopic travel remaining between the male

and female sections. Raise and lower the

sprayer to check that the PTO telescopic tubes

overlap by approximately 1/3rd their length, and

not less than 150mm, in all operating positions.

If the PTO shaft must be shortened cut equal

amounts from both male and female shafts and

safety covers. Carefully remove all burrs then

clean and relubricate before reassembling.

If the operating angles of the PTO shaft exceed

350a constant velocity joint must be fitted by

your Silvan dealer.

Operation

350Maximum

PTO OPERATING ANGLE

Starting the Sprayer

When starting the sprayer for the first time

conduct a trial run using clean water only (no

chemicals) to become familiar with the operation

of the controls and to check that all systems are

functioning correctly without any leakage.

Before filling the tank ensure that the drain cap is

fitted and the basket strainer is in place and

clean. Close the lid securely after filling.

SHUT OFF VALVE AND SUCTION FILTER

DRAIN CAP

The suction filter is fitted with a shut-off valve which

closes automatically when the valve cap is

screwed off. This allows the filter cover to be

unscrewed and the element to be removed for

cleaning while there is fluid in the tank. Gloves

should be worn when handling the filter.

Page 8

GEARBOX IN ENGAGED POSITION

When the sprayer is operating the valve must be fully

screwed in to open the shut-off valve and allow fluid

to pass through the filter. Directional arrows are

moulded into the valve cap to show the opening and

closing operation.

Check that the oil level in the diaphragm pump is

level with the mark in the viewer and if necessary top

up with SAE 20W-40 multigrade engine oil. When

starting for the first time ensure that the gearbox oil

level is correct and that the PTO has been lubricated

- refer Maintenance section.

Operation

Check that the fan gearbox is engaged. The

selector lever should be in the up position. Never

engage the fan drive with the tractor engine

running or the PTO engaged. Moving the lever to

the down position puts the gearbox into neutral and

the pump will operate without the fan.

Flip the required number of spray nozzles to the

open position, refer to page 10. Refer to the

Calibration section for information on nozzles and

jet selection.

Before engaging the PTO, move the by-pass

control “A” to the by-pass position (clockwise) and

close the outlet valves “C”.

Engage the tractor PTO slowly and allow the

sprayer to run in by-pass mode. Once the pump is

primed increase the tractor speed to 540 PTO rpm.

The by-pass lever can then be moved to the

operating or pressure position (anti-clockwise) and

the pressure can be adjusted by regulator knob “B”

whilst observing the gauge.

Depending upon the type fitted, the pump is

designed to operate up to a maximum pressure

of either 30 Bar (435 psi) or 40 Bar (580 psi).

Refer to the pump identification plate and the

Specifications page for details.

The pressure used for spraying may be varied

between 10 Bar (145 psi) and the pump’s

maximum depending upon the application rate -

refer to the Calibration section.

Open the outlet valves to commence spraying.

Two and Three Outlet Control Units

The 200 litre Airblast sprayer is fitted with a two

outlet control. The 400 and 500 litre models use

a three outlet control with two outlets connected

to the airblast nozzles whilst the third can be

used to connect a spray gun or other device. The

operation of both control units is the same.

The selection of by-pass or pressure mode is

controlled by the lever “A” - refer diagrams

below. Moving the lever clockwise through its full

travel selects by-pass which reduces the pumps

operating pressure by allowing liquid to bypass

the pressure regulator. Note, this operation does

not fully shut off the flow to the individual outlet

taps. Moving the lever full anti-clockwise, re-

directs pressurised fluid to the outlets.

Operation

System pressure is regulated by turning knob “B” and

observing the reading on the gauge. Turning the

knob clockwise increases the pressure and turning

anti-clockwise decreases pressure.

Fluid is directed to the airblast nozzles by outlet

valves “C” which are open when the lever is in line

with the direction of flow and closed when across the

direction of flow. The valves may be operated

individually to direct spray to either side or as a pair

to spray simultaneously from both sides .

If you wish to stop spraying but leave the tractor PTO

running, close the outlet valves “C” and move the by-

pass lever “A” to by-pass mode.

For spraying applications using only the third outlet,

on those models fitted with three outlet valves, the

fan can be disengaged to reduce unnecessary wear

and fuel consumption.

Flip On/Off Nozzles

Warning ! Relieve pressure in spray lines before

turning nozzles on.

The flip on/off nozzles incorporate an off position to

allow individual jets to be turned off when not

needed. The jets can be positioned by loosening the

attaching locknut and aligning the outlet to the

required angle. These two features enable the spray

pattern to be regulated to achieve the required

coverage without wastage of chemicals.

The nozzles fitted to 200 litre sprayers have a

single outlet which is turned on or off by rotating

the nozzle through 900.

DOUBLE OUTLET NOZZLE

SINGLE OUTLET NOZZLE

The nozzles fitted to 400 and 500 litre sprayers

have two outlet jets, one at each end of the

nozzle, but only the jet which is flipped to the

outward facing position is “on”. This facilitates

convenient changing between jets of different

sizes, for example, when requiring application

rates to suit concentrate and dilute spraying.

LOCKNUT

Both types of nozzle incorporate ceramic jets,

stainless steel swirl plates and stainless steel

mesh strainers, separated by neoprene gaskets.

The purpose of the swirl plate is to create a

conical spray pattern. Nozzle output at a

particular spray pressure can be varied by fitting

different combinations of jet and swirl plate as

shown in the Nozzle Output Chart on page 13.

Ceramic jets are sized according to the diameter

of the central hole in millimetres.

Swirl plates can either have a closed centre,

identified as CC, or a central hole which is sized

in millimetres. Closed centre swirl plates produce

a hollow cone spray pattern and are fitted for low

outputs. At higher outputs, swirl plates with a

central hole are necessary to fill the centre of the

conical spray pattern.

Ceramic jets and swirl plates normally have a

long wear life and require little maintenance other

than regular checking and cleaning of strainers.

The spray pattern should be observed

periodically against a dark background to detect

signs of wear which will be indicated by a streaky

or broken pattern. If worn jets are detected then

the full set of jets, swirl plates and gaskets

should be replaced.
