Secure all operating media like compressed
¾
air and hydraulics against unintended com-
missioning.
Repair work inside the spraying mixture con-
¾
tainer must only be performed after thorough
cleaning and wearing protective outfit with a
respirator. This work must be monitored by a
second person outside the spraying mixture
container for safety reasons! Ensure sufficient
ventilation of the spraying mixture container!
Before cleaning the machine with high pres-
¾
sure cleaner cover all openings, which should
stay clear of water, steam or cleaning agents
for reasons of safety or operation. Do not aim
the water jet directly on electric or electronic
components and bearings.
When cleaning with high pressure cleaning
¾
equipment or steam jet keep a distance of at
least 50 cm to machine components.
After cleaning, check all hydraulic lines for
¾
leaks and loose connections.
Check for chafing and signs of damage. Rem-
¾
edy any faults immediately!
Screw connections loosened for the purpose
¾
of care and maintenance work must be
retighten after work is completed.
Dispose of oils, greases and filters according
¾
to regulations!
If protective features are subjected to wear,
¾
they must be inspected at regular intervals
and replaced in due time
Do not clean new machines with a steam jet
¾
of a high pressure cleaner. The paint takes
approx. 3 months to cure and could be dam-
aged before this time.
Pay attention to the following when repairing
¾
the machine that has been used for liquid
fertilising with ammonium nitrate - carbonyl
diamide solution:
Residues of ammonium nitrate - carbonyl
diamide solution may form salt on or inside
the spraying mixture container through the
evaporation of water. This results in pure am-
monium nitrate and carbonyl diamide. In its
pure form, ammonium nitrate in connection
with organic matter, such as carbonyl diamide,
becomes explosive, if critical temperatures
(caused by e.g. welding work, grinding) are
reached during repair work.
By thoroughly cleaning the spraying mixture
container or the parts to be repaired with
water, this risk can be eliminated, because
the salt of the ammonium nitrate - carbonyl
diamide solution is water-soluble.
All other maintenance and repair tasks,
¾
which are not described in the operating
instructions, must only be carried out by
an authorized professional workshop or
by an operator who has been trained by
HORSCH for this purpose.
