New Product Warranty The Silvan Warranty This warranty is the only warranty applicable to Silvan new products ('Products') and, to the maximum extent permitted by law, is expressly in lieu of any other conditions or warranties expressed or implied in relation to the Products. Subject only to legislative obligations to the contrary, Silvan shall not be liable for incidental or consequential damage resulting from ownership or use of a Product.
Safety Information Before operating the sprayer read the following safety instructions. Failure to comply with these warnings may result in serious injury or death. Whilst your Silvan linkage sprayer has been designed and manufactured to incorporate all necessary safety features it is essential that any person who operates or works on the machine is aware of the safety precautions that should be exercised.
Safety Information The location and wording of the safety decals fitted to Silvan linkage sprayers is shown below. It is important that all operators read and follow the information on all safety decals before operating the sprayer. Failure to comply with these warnings could result in serious injury or death. Safety decals should be kept clean and legible at all times.

Pumps Constant displacement oil backed diaphragm pump of varying size depending on sprayer specification. Output at maximum permitted 540 PTO rpm with maximum operating pressure as shown below. Pump No.
Operation Attaching to the Tractor Most Silvan linkage sprayers are equipped to fit tractors with either Category 1 or 2 linkages. The inner end of each lower linkage pin is Category 1 diameter and the outer end is Category 2. The lower holes in the top connection plates are Category 1 diameter and the upper holes are Category 2. The 800 litre heavy duty and 1000 litre models are equipped for Category 2 only. Remove the PTO shaft from the sprayer by depressing the locking pin.
1 Operation operating or pressure position and the pressure can be adjusted by turning the regulator knob and observing the reading on the gauge. Depending upon the particular type fitted, the pump is designed to operate up to a maximum pressure of either 15 bar (218 psi) or 20 bar (290 psi). Refer to the pump identification plate and the specifications page for details.
Operation Single Flow Control “D” swing over to open all valves Outlet Valves “C” open By-pass Control “A” Outlet Valves “C” Pressure Regulator “B” Operation 1. Set the by-pass control to pressure mode (lever “A” down). 2. Adjust the maximum system pressure with pressure regulator “B” until the gauge reads approximately 15 Bar. 3. Adjust the spraying pressure with regulator “D” until the pressure drops to your required operating pressure (turn knob anti-clockwise to reduce pressure). 4.
Operation Silvamatic Control Unit (continued) Suck Back Device The Silvamatic control incorporates a suck back device which operates on all open outlets while the selector lever is in by-pass. This prevents the boom nozzles dripping if the tractor PTO is running while the unit is not spraying. Self Cleaning Filter A self cleaning filter is incorporated in the control unit to remove impurities from fluid pumped to the boom.
Operation Boom Filters The Padboom is fitted with three in-line filters on the mounting frame, each providing additional filtration to one section of the boom before the fluid reaches the spray nozzles. These filters may be fitted as optional equipment on other types of Silvan booms. Unscrew the filter bowls and clean the filters daily as described in the maintenance section of this manual. Avoid chemical contamination by wearing gloves.
General Spraying and Boom Information When to Spray Results will be best when the wind speed is low, temperature is low and relative humidity high. An ideal time is at sun up when these conditions are most likely to apply. Field Patterns For overall coverage, spray two swaths around the outer perimeter of the field to establish a wide headland on which to turn. Make subsequent passes across the field following the direction of drilling. Turn the sprayer on and off as the boom passes over the headland.
Calibrating the Sprayer Spray Pattern and Nozzle Uniformity The overlap pattern of the boom, the spray pattern of individual nozzles and the uniformity of nozzle output can be tested in the following manner. Always keep one new nozzle aside from each set to use as comparator for this test. 1. Install the comparator nozzle, fill the sprayer tank with clean water and operate the boom at spraying pressure whilst stationary. 2. Examine the spray pattern from each nozzle against a dark background.
Calibrating the Sprayer All Silvan booms other than the Fieldmaster boom are fitted with TP nozzles suitable for a pressure range from 2.0 to 4.0 Bar. The chart below applies to these booms. Nozzle Selection Refer to the chemical manufacturer’s information to determine the recommended application rate in litres per hectare (l/ha) for your particular situation.
Calibrating the Sprayer Alternatively, the same rate of 100 l/ha could also be achieved with a larger nozzle and faster operating speed. By referring to the Teejet TP nozzle chart on the previous page it can be seen that an TP8003 or TP11003 blue nozzle will give this rate at a little under 14 km/hr and 3.0 Bar (the rate shown on the chart at 14 km/hr is 103 l/ha ). Similarly an XR8003 or XR11003 blue nozzle will also give 100 l/ha at a little under 14 km/hr and pressure of 3.
Optional Equipment Tighten the two clamping screws firmly. Foam Markers All Silvan linkage sprayers can be fitted with 14L or 30L Foam markers. Refer to the Foam Marker Operator’s Manual for installation and operating procedures relevant to the type of marker fitted to your sprayer. Boom End Taps The end tap is a simple 1/2” BSP connection and on/off tap with hose elbow which can be screwed into the end of the boom sprayline to allow direct flushing of any chemical residues after spraying is finished.
Optional Equipment does not rub on any sharp edges, or use a rubber grommet. Connect the tractor loom to the sprayer loom with the quick release coupling. Ensure the loom is clear of the PTO shaft and tractor wheels.

Lubrication and Maintenance Daily Maintenance Before carrying out any maintenance, please switch off the tractor and disconnect the drive shaft. Never leave chemicals in the tank that may settle to the bottom, harden and break into lumps as this may block the suction filter. Weekly Maintenance General During the first few days of operation, before starting each day check that all hardware is tight and inspect the unit for leaks while running and tighten all hose clamps.
