GENERAL SAFETY This machine must only be used for the purpose for which it was intended i.e. crop spraying. It is against the law for anybody to operate a machine that they do not understand. Please read this handbook carefully before attempting to operate the sprayer. In order to comply with the Health and Safety at Work Act, the sprayer must be thoroughly washed and decontaminated before any person may be permitted to carry out repairs or adjustments.

Finally, it would be prudent to check for fatigue marking in highly stressed areas and associated components, on a regular basis. Should any item give cause for concern then contact SAM Ltd immediately. SAFETY FIRST All agricultural equipment can be hazardous. When a SAM sprayer is correctly operated and properly maintained, it is a safe machine to work with, but when it is carelessly operated or poorly maintained it can become a danger to you (the operator) and others.
Read the safety instructions before operating the machine. If you do not understand anything, ask your employer or SAM Ltd to explain it. Keep this handbook clean and in good condition. Do not operate the machine without a handbook in the cab, or if there is anything you do not understand.

Section 2-2 MACHINE CONTROLS 3000, 3000E & 3500 - Cabin The Horizon 3000, 3000E & 3500 Cabin is different to the remainder of the other Horizon machines. This Section is only to identify any differences in Cabin layout - The main components are identified above and then explained in further details on the subsequent pages.
Steering Column The pictures above show the layout of the dash and steering column controls as presented to the driver of the Horizon 3000, 3000E & 3500 machine. The steering column is adjustable for both rake and reach. The fuses attached to the steering column are described in Section 6.2 of this manual.

The above picture shows the two overhead control panels, the radio and climate control panels are exactly the same as other Horizon machines. The left panel identifies the four switches which operate the front/rear cab working lights, the warning beacons and the boom working lights.
POWER UNIT All SAM Sprayers are powered by Deutz water-cooled industrial diesel engines. These engines meet all current E.U. Emission Standards. Power ratings are matched to the gross weight of each machine plus any extra demand required (e.g. air stream fan).
Rear end hydraulics on SAM Horizon sprayers are of the 'Load Sensing' type. This advanced system uses a large variable output swash plate pump to produce only the oil that is required for any function. It does not produce any surplus oil and as such produces very little heat.
A change of colour identifies a fault - contact SAM. SUSPENSION A self-levelling suspension system is fitted to the SAM 'Horizon' Sprayers. Normal suspension is provided by hydraulic rams and gas accumulators fitted at each corner of the machine. The accumulator pre-charge has been set at the factory and needs no further adjustments.
TYRES - FLOATATION The range of floatation wheels available for SAM sprayers is vast. SAM would not advocate using pressures in any floatation wheel below 1 Bar (15 psi). The ultra low pressures of bygone years have proved to be of no particular advantage to the soil or the crops.
TYRES - CUSTOMER / OPERATOR Wheels and Tyre Information With your sprayer are a number of options, which are designed to optimize your sprayers' performance, dependant on your land, terrain, crop and weather conditions. Using the Sprayer - General Operation Initial consultation in operations, usage and requirements to decide on you optimised wheel options is important in getting the maximum out of the vehicle, - with a sprayer, there are three main permutations of tyre/wheel equipment.
Normal drive radial tyres have a maximum capacity rated at 1.6bar and 40kph. Narrow tyres have a maximum capacity rated at 2.4, 3.2 or 3.6bar and 40kph Latest technology - Flexible sidewall tyres, consult data sheets, SAM or your tyre specialist TYRES - OPERATING INFORMATION...
TYRES - OPERATING INFORMATION Tightening of Wheels The nuts should be tightened in a star order and should be tightened to the specified torque. After driving about 100M and before placing them under load, re-tighten nuts to specified torque. Check wheels and nuts after operating sprayer for 3 hours and again after 10 hours. Check wheels and nuts frequently and keep them tight.
DUAL WHEELS Dual wheels are a poor alternative to flotation wheels. They are less flexible than the single wheel option and transmit very high shock loads into associated components. SAM would suggest a 30% reduction in speed be implemented. TRACK ADJUSTMENT All standard sprayers have the same track capability via adjustable axles 1830mm (72”) –...
HYDRAULIC ADJUST AXLES The engine must be stopped, the parking brake applied and the front wheels chocked. Lift one end of the machine until the tyres are clear of the ground. Loosen the two clamps at either end of the axle beam.
All filters must be changed after the first 10 hours and, thereafter, every 250 hours or when the clogging indicator shows a blockage, whichever comes first. SAM LTD ONLY RECOMMENDS THE USE OF SAM SUCTION AND RETURN FILTERS. When changing oil filters, always change the O Ring with the correct one supplied.
Air is fed throughout the machine via a filter/lubricator assembly located at the right hand end of the cat walk. With lubricator Without lubricator SAM Ltd recommends the use of 'Tellus 37' lubricant in the Due to a recent product development, the system now lubricator bowl.
SPRAY TANK The heavy-duty baffled fibreglass tank has a nominal capacity of between 4000 litres (880 gallons) and 5500 litres (1210 gallons) depending on specification and is suitable for all agrochemicals. The charging hole in the top of the tank holds a large capacity filter basket. The tank lid is fitted with a breather but if filling is being carried out with a high capacity pump, it is advisable to remove this lid to prevent excessive pressure build up in the tank.
CHEMICAL INDUCTION HOPPER This hopper is normally stowed at the rear of the machine alongside the spray pump and is of the Venturi type. The booms should be lifted to enable the hopper to swing out and down to the working position.
SPRAY LINES A single stainless steel ¾” Sprayline is a standard fit to all Horizon models. Each complete boom is normally fitted with seven Sprayline sections all controllable from the cab and each section is fitted with a ‘Duo-React’...
GULLWING SPRAY BOOMS The SAM Gullwing folding boom of up to 36 metres in width is based on the well-proven space frame construction. The folding mechanism is in-cab controlled with two Finger Tip switches (booms up to 24m) or three Finger Tip switches for booms larger than 24m After lifting the boom clear of its rest, both main sections may be opened to 12m.
GULLWING SPRAY BOOMS - 36M & 40M Supplement A 36 metre Gullwing Spray Boom is capable of spraying at 24 metres and 12 metres. Never fold a boom over 24m without the boom first being locked! Prior to any folding operation it would be advisable to momentarily select the opposite folding direction in order to release the load from the boom locks.
AUTOMATIC SPRAY CONTROL All SAM machines are fitted with an Auto Spray Control System. Several different types of systems are used depending on the application and customer choice. A full set of operating instructions for the system fitted are provided.
FILLING THE SPRAY TANK WITHOUT SELF FILL ATTACHMENT 1. Fill the tank with a minimum of 100 litres (20 gallons) of clean water through the charging hole filter basket. 2. Ensure the rotary 'Suction' tap is positioned to 'Spray Tank' and the rotary 'Pressure' tap should be positioned to 'Spray'.
WASHING OUT THE SPRAY TANK A Tank Washing facility is installed which enables the EMPTY tank and booms to be flushed with clean water prior to leaving the field. Tank washing can be accomplished in two ways - either from the operators seat or the rear left of the sprayer. If a ‘double’...
PESTICIDE SPRAYING & THE ENVIRONMENT Used correctly, pesticides do not pose any more of a threat than many other modern inventions. Used incorrectly or thoughtlessly then problems may occur. As commercial users of pesticides, the following points should be observed as guidelines on the safe use of pesticides.
PESTICIDE SPRAYING - FIELD CRAFT Before any spraying takes place, check the following: Is the pesticide the correct one for the crop? Is the dose, volume or both correct? Is the weather suitable at present and going to remain so? (You do not want half a tank of pesticide left should it rain.) Ensure the wind speed and direction will not blow any drift to other crops, waterways, private gardens or members of the public.
