Safety information

±
WARNING! Working near overhead power lines can be dangerous
and special precautions should be taken. You are considered as
working near overhead power lines when the sprayer or the
booms can reach minimum "priming" distances. This distance
can be up to 2 metres for low voltage lines and up to 8 metres for
very high voltage lines. When you unfold or fold away the booms,
warn any personnel on the ground to keep a sufficient distance
away from the sprayer.
If the machine comes into contact with a power line, above all
you must not leave the seat of the vehicle. Otherwise, you could
be electrocuted by placing your foot on the ground. Wait for help
from the electricity company and keep everyone away from the
machine. A sticker placed on the windscreen contains the safety instructions.
÷
NOTE! Before folding or unfolding the boom, make sure that no one is in the operating area of the boom.
÷
NOTE! If maintenance work has to be carried out on the boom hydraulic system, ensure that it is completely unfolded
and placed on steady axle stands.
÷
NOTE! The boom must always be folded and unfolded with the machine shut down. If this rule is not observed you
risk damaging the booms.
