the ground or supported prior to working underneath. If working on the Pneumatic systems, the
pneumatics must be depressurised.
2.9.6 - Pressure Accumulators
The hydraulic system on the SPX 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.
2.9.7 - 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.
2.9.8 - 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.
