1. This machine must only be used for the purpose for which it was intended i.e. crop spraying.
2. 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.
3. 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.
4. Be aware of the COSHH Regulations and comply with them at all times.
5. Always wear protective clothing when working with chemicals.
6. Always read the label on the chemical container carefully.
7. The machine must not be used for spraying sulphuric acid unless it has been modified for this purpose.
8. Never operate the sprayer until all guards are in place.
9. Never start the machine until all personnel are clear.
10. Never perform maintenance or repair work while the machine is running. If you are working on a part of the
machine not visible from the cab, remove the ignition key.
11. Never work under the machine when it is standing on a jack unless it is properly supported.
12. Extra care should be taken when working on steep hills, as is normal practice with any high clearance tractor.
Beware of 'soft spots' and 'pot holes'. Never spray across a dangerously steep hill and never spray across a
steep hill with the uppermost boom folded. Wider wheel settings aid stability.
13. Ensure that any replaced component, hose or fitting is of the same specification as that originally fitted. All
hydraulic hoses carry an identification number.
14. If frost is expected, anti-freeze should be pumped through the complete spraying system and/or drain down.
15. Before going onto the road, check brakes, lights, indicators and tyre pressures. Ensure 4WS is disengaged
(4WS Indicators are extinguished on Over Head Control Panel and Vehicle is in ‘Road Mode’).
16. Extra care should be taken when servicing the battery (always isolate first). The sulphuric acid contained
within the battery can cause severe burns as well as explosive gases. Keep cigarettes and sparks away.
17. This machine contains an air reservoir with a maximum pressure rating of 10 bar. The reservoir should be
checked on an annual basis by a recognised inspector.
18. As with any high clearance machine with a high centre of gravity, the stability of that machine is directly related
to its wheel track width. As tractors have grown in size, their ability to achieve narrow track widths has
diminished. Like the tractor, the sprayer track width should also reflect this philosophy.
A 'risk assessment' and 'duty of care' is part of modern farming life and the farmer/contractor has a legal
responsibility to consider the sprayer track width in relation to stability in order to achieve a safe working
environment.
19. Before any spraying operation and prior to field entry, the spray operator should commence a mental risk
assessment of the area. All risks, however minor, should be recorded in some way for later reference by any
operator.
Notable risks should include water courses, footpaths, local housing, gradients, pylons and poles, power
cables, adjoining crops, wind direction etc.
20. An Emergency Hammer is provided within the Cab to smash any window to act as an emergency exit.
The hammer blow should be directed at the corner of the window. The right hand door can also be used
as an emergency escape route.
GENERAL SAFETY
1-1

6
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.
In this handbook and on the machine you will find warning messages. Read and understand them. They tell
you of potential hazards and how to avoid them. If you do not fully understand the warning messages, ask
your employer or SAM Ltd to explain them.
However, safety is not just a matter of responding to the warnings. All the time you are working on or with the
machine, you must be thinking what hazards there might be and how to avoid them.
Do not work with the machine until you are sure that you can control it.
Do not start any job until you are sure that you and those around you will be safe.
If you are unsure of anything, about the machine or the job, ask someone who knows. Do not assume
anything.
SAFETY FIRST
SAFETY CRITICAL ITEMS
The braking and steering systems fitted on the sprayer are both safety critical services. These systems
should be thoroughly inspected at least every 250 hours and should coincide with the hydraulic filter changes.
The two braking systems fitted (Primary and Parking) require only a visual inspection around the wheel
motors. The multi-disc parking brake fitted to each rear wheel motor should be inspected for back plate spring
integrity and oil leaks from this area.
The steering system consists of several components, all of which should be checked for tightness, in
particular the fixings of the ball joint tapers plus the split pin, the ball joint, track rod, lock nut and the steering
cylinder.
In the case of adjustable axles, the track rod-adjusting bolt and axle clamp should be checked. Axle
adjustment is covered in the following pages of this instruction book but we should emphasise that both front
and rear axle fixings should be re-checked for tightness after a few hours work. A weekly visual inspection
should also be initiated.
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.

If Field Mode is selected, moving the Joystick forward will drive the machine forward. The further forward the
Joystick is pushed, the faster the machine will travel but is limited by the set Engine RPM.
If Road Mode is selected the engine RPM remains at idle until the Joystick is moved (or the optional Travel
Pedal is pressed). On a 4000 sprayer the engine RPM increases and the machine will pull away with the wheel
motors in half displacement until the maximum speed of 40kph is reached. A 5500 sprayer automatically
changes displacement until the maximum speed is reached.
If the joystick is returned to neutral, the sprayer will stop. The quicker the Joystick is moved, the quicker the
response, whether it be acceleration or braking. Care must be taken not to induce skidding by moving the
Joystick too rapidly.
If greater braking is required, than the joystick provides, then the Brake Pedal can be depressed (if fitted). This
will provide braking torque on the front wheels (Horizon 4000) or all four wheels (Horizon 5500) as well as the
hydrostatic braking. After using the foot brake, the Joystick must be returned to the corresponding braked
speed before the machine will accelerate.
Moving the joystick backwards drives the machine in reverse and the same rules apply.
If the optional Travel Pedal is fitted and selected, then the joystick has to be moved fully forward or backward in
the first instance in order to dictate the direction of travel.
The engine can only be started with the joystick in neutral.

RPM -
The Engine Throttle control is a rotary wheel, which when moved in the forward
direction, the Engine RPM is increased. When moved in the rearward direction
the Engine RPM is decreased. The rotary wheel will remain in the position it was
left in, except in the case of the Horizon 5500. In this case the rotary wheel will
return to the central position because it operates in a momentary fashion. When
moved in the forward / rearward direction momentarily, the rpm will increase /
decrease in according steps, if held in position the RPM will change more rapidly.
The Engine Throttle will only operate while in Field Mode, as when in Road Mode
the RPM is controlled via the Joystick / Travel Pedal.
If the Engine Throttle was not at idle before switching to Road Mode, when
switching back to Field Mode the Engine Speed will return to the original RPM.

Park Brake / Step - Applying the Park Brake also lowers the Step.
If the Park Brake is not applied before attempting to leave the Cab, injury may result!
Remember that removing the Park Brake will raise the Step - ENSURE that the Step area is clear before
removing / applying the Park Brake!
Field Mode / 4 Wheel Steer Unlocked - For normal field work, it also unlocks the 4WS system allowing the
operator to engage 4WS by either pressing the 4WS Foot Switch, or the 4WS Engaged Spray OFF or 4WS
Engaged Permanently.
Normal / Uphill Traction - For flat land, steep uphill and moderate downhill spraying. Gives best overall
performance.
Remember: if the machine will not climb the hill in Normal / Uphill, never attempt to descend the hill.
Downhill Traction - For descending a steep hill when traction is marginal. If Normal / Uphill is being used and
the rear wheels begin to skip, Downhill may be selected on the move.
Maximum Traction - all wheel motors with full power capability – generally only suitable on flat land.
Road Mode / 4 Wheel Steer Locked- For driving on highways, maximum speed but with reduced motor
torque. Also locks the 4WS system (once the rear wheels have straightened up) to prevent 4WS use. Ensure
that the 4WS system is disengaged before entering a public highway.
The vehicle has a permanent four-wheel drive system but this is only relevant when all wheels can provide
tractive effort.
Cruise Control - Activates Cruise Control, only available on the Horizon 5500 Sprayers.
Set / Decrease - will SET the speed at which the Sprayer is travelling as the cruise speed. Once set the speed
can be increased or decreased by momentary operation of Reset / - or Set / + buttons (approx 0.5km/h each
time). Pressing the button again will decrease the vehicle speed by a predetermined amount.
Pressing the Brake Pedal or turning off Cruise Control will cancel Cruise Control.
Reset / Increase - will RESET the cruise control to the previous cruise speed. Pressing the button again will
