Misuse of the machine can cause accidents with severe injuries, property damage or fatalities as
outcomes. Consequentially only personnel trained and instructed on this implement may work on
or with it. This training must occur under the instruction of an experienced operator.
2.6 - Personnel Training
2.5 - Danger Area & Danger Points
The area immediately surrounding the implement and tractor is hazardous to personnel. Whilst
within this zone all personnel should pay attention to the machine status and if parts can move,
failure to pay adequate attention can result in serious injury or even death. The operator must
therefore ensure no personnel are in this zone prior to machine movements or component
actuation (Such as unfolding the wings) Components of the machine can actuate unexpectedly
impacting personnel causing serious injuries especially if unsighted by the operator. Lifted loads
and components should be lowered to the ground to reduce the risk of injury and hydraulically
lifted components can slowly lower over time causing crushing injuries. It is therefore highly
recommended if any work is being carried out the tractor is prevented from restarting even for
short term inspections, or if personnel are in the danger area they are advised to move, and the
operator ceases work until this is the case. If carrying out maintenance and service work under
actuated or lifted components, please see section 2.12 in relation to the measures that must be
undertaken to ensure safety.
Warning stickers are fitted in key areas to highlight dangers applicable in this area. Some
components such as hydraulic or pneumatic systems can store residual energy even if the tractor
is isolated from restarting. Therefore, information regarding the removal of the residual energy is
detailed in the systems or components relevant chapter.
Please note however Hydraulic accumulators such as those utilised on the hydraulic braking
system will always have some residual energy stored within see section 2.9.6 in relation to these
components. Some components and systems such as the distribution fan are fitted with a guard
to reduce the likelihood of injuries. Such guards should always be fitted whilst the implement is in
operation and should only be removed when all components have come to rest, and the machine is
secured against unexpected start up.

2.7 - Personal Protective Equipment
Incomplete or missing Personal Protective Equipment (PPE) can increase the risk of health damage.
PPE includes but is not limited to:
• Protective clothing/Tight fighting clothes
• Safety shoes
• Safety gloves
• Eye protection (Safety goggles/Glasses)
• PPE appropriate to the handling of dressed seed or fertiliser & Liquid fertiliser
products (PPE equipment appropriate to the manufacturer’s instructions e.g.
Respirator, safety gloves and eye protection)
• Removal of rings or loose jewellery items as well as securing long hair from
entrapment (Such as with a hair net)
PPE should be eective and in proper working condition prior to usage as well as appropriate for
the task being undertaken by the operator. PPE should not hinder the operator’s eectiveness to
work where such PPE is required.
2.8 - Safety In Traic
The operator must comply with all applicable height, width and weight restrictions whilst
transporting the implement. The tractor should be ballasted accordingly (as shown in section 3.4)
to maintain steering and braking capacity. Maximum permissible total weights, axle loads or tyre
load bearing capacities must not be exceeded.
Trained Operators – Personnel trained in the risks of their assigned task/s and can used the
required PPE and follow the preventative measures included in this manual to avoid incidents.
These Personnel can be trained by the implement owner (Assuming they are adequately qualified)
or other experienced personnel
Personnel with specialist training – These personnel typically have a qualification or relevant
experience to understand the risks and dangers posed by their assigned task. Furthermore, they
can apply the knowledge of appropriate regulations to their working practices. These personnel can
also carry out the procedures requiring specialised tooling or equipment (Indicated by Workshop
Maintenance later in the manual
All personnel must be able to operate the implement in accordance with this owner’s manual
and be able to appropriately apply the information to their working procedures. Any apprentices
or untrained personnel must be closely supervised by an experienced person. Operators must
know road traic regulations applicable to their country and hold a valid licence when moving
the implement and tractor on a public highway. Additionally, operators must be aware of machine
functionality and operation to avoid specific dangers relating to the work being undertaken.
Implement owners must make this operator’s manual available to all personnel operating or
working on this implement, ensuring all personnel are trained and instructed as required.

12 |
2.9 - Operational Safety
2.9.1 - Commissioning
The implement should be properly commissioned prior to first usage, failure to do so can impact
on the operational safety of the implement placing the operator, other personnel, and property at
risk of severe damage, injuries or even fatalities. Tyre pressures should be checked and nuts and
bolts checked for tight fitment. In particular wheel nuts and any fixings securing the cultivation
equipment should be checked. Loose fixings can cause components to detach impacting on the
operational safety.
2.9.4 - Hydraulic System
2.9.2 - Damage to the Implement
Any damage to the implement can impact on the operational safety of the equipment. Some
components are critical to the operational safety of the equipment and therefore any damage to
these must be remedied immediately. Hydraulic systems, braking systems, the hitching elements,
any connections between the implement and tractor and the signalling equipment should be
checked prior to all machine operations due to their impact on the operational safety if damaged.
Coulter elements should also be regularly checked for damage and wear prior to usage to ensure
accurate product distribution.
2.9.3 - Hitching/Unhitching
Failure to correctly connect the implement to the tractor can result in severe accidents or
property damage. Connecting and disconnecting the implement to the tractor can be found in
section 6.1, however there are still several risks when performing this procedure. When making
any connections/disconnections between the implement and the tractor all systems should be
depressurised and personnel should never enter the space between the implement and machine.
If a single operator is performing this procedure external lift controls should be utilised if fitted. All
parts (Implement and Tractor) should be on stable flat surfaces and secured against rolling away
or becoming unstable. Braking connections must also be performed prior to releasing the parking
brake to ensure control.
The hydraulic systems on the implement operate under high pressure. Escaping hydraulic fluid
The implement must also be folded and placed in the transport position as shown in chapter
6.1.2. Before travel mud and dirt should be removed from the implement, lighting and signalling
equipment should be checked for functionality. Whilst transporting the implement the operator
must consider the eects local weather and road conditions will have on the tractor and implement
as well as implement overhangs, dimensions, and the inertial mass of the machine when cornering
or braking, they should also consider local regulations and any applicable height width or weight
restrictions along the planned route. For transport on public roads the hoppers must be emptied of
any product. Failure to do so invalidates the type approval and places the operator, other personnel
and property at greater risk of injury, death or material damages.

can penetrate the skin causing serious injuries or death. If injured by escaping hydraulic fluid
immediately contact your local doctor. The hydraulic system of the implement has several functions.
Incorrect operation of this system can cause serious injury or death to personnel and/or material
damages. Hydraulic systems should only be operated at their recommended pressures to prolong
the service life of components.

To reduce the risks of injury and damages occurring the operator must connect/disconnect hoses
between the implement and tractor only when the system is depressurised. The connections
between implement and tractor are marked as shown in section 5.3 to reduce handling errors
and ensure proper connection order. Connections, hydraulic lines, and hoses should be regularly
checked for leaks, signs of external damage and wear. When checking for hydraulic leaks only
use appropriate means of checking the system. If any damage is found the components should be
replaced as soon as possible due to the increased risk from oil sprays causing injuries and fires.
With the component replace any spilled hydraulic oil should also be cleaned from the machine.
Hydraulic hoses should be replaced every 6 years due to fatiguing as the components age. Prior
to any work being undertaken on the machine the control unit must be locked and secured and
any hydraulically raised components must be lowered to the ground or supported prior to working
underneath. If working on the hydraulic systems, the hydraulics must be depressurised.
2.9.5 - Pneumatic System
The pneumatic systems on the implement operates under high pressure. The pneumatic system
on the implement has several functions. Incorrect operation of the pneumatic systems can cause
serious injuries or death to personnel and/or material damages. Pneumatic systems must only be
operated within their recommended pressures to prolong the service life of components.
To reduce the risks of injury and damages occurring the operator must connect/disconnect hoses
between the implement and tractor only when the system is depressurised, prior to connecting
the hose the operator must ensure both the tractor connection and the hose is clean and free
from any debris. The connections between implement and tractor are marked as shown in section
5.5 to reduce handling errors and ensure proper connection. Connections, Pneumatic lines, and
hoses should be regularly checked for signs of external wear or damage. The system can also be
pressurised to check for leaks.
Damaged components or leaks should be replaced/ fixed as soon as possible to reduce stresses
placed upon other components. Prior to any work being undertaken on the machine the control
unit must be locked and secured and any Pneumatically raised components must be lowered to

14 |
The hydraulic system on the DSX is equipped with pressurised accumulators. Even when the
hydraulic system is depressurised the accumulators contain a high gas pressure. Consequentially
they should never be driller or welded even with the hydraulic system depressurised. The hydraulic
circuit must be depressurised prior to any maintenance or disassembly work being undertaken. The
accumulators are pre-charged with nitrogen gas. If this gas is released in confined spaces, it is an
asphyxiation hazard.
2.9.6 - Pressure Accumulators
2.9.7 - Braking System
The implement is equipped with either a Pneumatically or Hydraulically actuated braking system as
standard. The braking system must always be connected and operating eectively when the tractor
is in use particularly when travelling on public roads this also includes the usage of the breakaway
valve system if fitted (Applicable to hydraulically operated brakes) see section 6.1.4. Once the brake
coupling has been made but prior to transport operations beginning the implement and tractor
must be checked for eective operation. Prior to any machine movements the parking brake should
be released. The implement should be secured with the parking brake prior to any uncoupling
operations commencing.
2.9.8 - Obstructions & Ovehead Power Lines
The operator must pay attention to surrounding obstructions and overhead powerlines, particularly
when the implement is in transport configuration, or when folding/unfolding the wings. All these
states pose the greatest risk of reaching overhead powerlines causing a voltage flashover or hitting
surrounding obstructions and causing damage to the implement. Voltage flashovers pose a risk of
fatal electrical shock or fire and as such the operator must keep a safe distance from any overhead
power lines when folding/unfolding or travelling under. The distance varies based upon the
powerline voltage. Wings should never be folded or unfolded, or the top of the machine accessed
whilst the machine is under a powerline. The operator should move the implement and tractor a
safe distance away to actuate the wings or refill the hoppers.
2.9.9 - Field Use
The implements condition and connections should be checked prior to undertaking any field
work. Damaged or worn components should be replaced. While working it is essential the operator
checks the surroundings for any persons entering the danger area, or for personnel standing in
the actuation path of hydraulically actuated components. No machine movements or actuations
should take place if personnel are in the danger area or path of these components. The implement
and tractor must never travel backwards whilst the coulters are engaged in the ground. Doing so
risks damaging and blocking the implement. The operator should check after an initial pass and at
regular intervals throughout work that the product is being applied at the correct depth and rate
required.
the ground or supported prior to working underneath. If working on the Pneumatic systems, the
pneumatics must be depressurised.

2.9.10 - Technical Limitations
Failure to follow the implements technical limitations can endanger the operators and other
personnel’s safety and risk material damages.
The technical limitations for this machine are as follows:
Along the contours: 10% left and right
Along the gradients; 10% up and down the slope
Operational Speeds: ≤12 Kph
Transporting Speeds: Refer to Tractor Manufacturers Manual for
details on tire pressures & speeds.
The implement must be empty prior to any road transport operations.
2.10 - Dressed Seed & Fertiliser
Failure to properly handle fertiliser and dressed seed can cause poisoning and even death.
Fertiliser and dressed seed should be stored as per the manufacturer’s instructions when not in
use. All information and instructions on the product manufacturers safety data sheet should be
followed, asking the supplier/manufacturer for a copy if necessary. The appropriate PPE can then
be determined for usage whilst handling the product.
2.11 - Enviromental Protection
Consumables such as Hydraulic oil, lubricants and other products can be hazardous to personnel
health and damaging to the environment. These consumables must not spill or drain out into the
environment. Should these products spill into the environment they must be recovered using
absorbent materials or sand. These contaminated absorbent materials should then be disposed of
in accordance with local regulations.
2.12 - Care & Maintenance
Unsuitable or inadequate care and maintenance can reduce the operational eectiveness and
safety of the implement, therefore increasing the risk of accidents with serious bodily injuries,
property damage or even fatalities as an outcome. Consequently, it is highly recommended
the operator follows the maintenance plan found in section 9.0 to service the machine at
the recommended intervals. Advice for how the work is undertaken on commonly replaced
components is included throughout this manual, for components not covered within this
document it is recommended to contact Horizon Agricultural Machinery Ltd. in case there are
specific handling procedures or risks posed through this component’s replacement. As such this
service work must only be carried out by an authorised workshop or operator trained by Horizon
Agricultural Machinery Ltd. for this purpose. The machine should be appropriately secured on
firm and level ground with all hydraulic and pneumatic systems depressurised, and electrical

2.14 - Modification & Conversions
connections isolated prior to any work being undertaken. Raised components should be lowered or
secured prior to work being undertaken underneath them.
When utilising a high-pressure cleaner areas around hydraulic seals, electrical components,
bearings seals or the fan should be avoided. It is also recommended that the nozzle outlet
maintains at least 50cm clearance from the machine during cleaning operations. Seed dressings
and fertilisers can Contaminate surfaces and components (Seed boots, hoppers, and the metering
system) Therefore it is recommended to use the manufacturers recommended PPE whilst working
or cleaning these areas.
