Dusting and spreading mode –
SR 450 only
The dusting and spreading mode can be
used for powder or dry granulate up to a
grain size of 5 mm.
Observe legal requirements for handling
the chemicals.
Observe the directions for use or the
label of the plant protection product.
Using the unit
Electrostatic charging with sparking can
occur when working with the dusting and
spreading attachment.
The risk is greatest
– in extremely dry weather conditions
– when using powdered products,
which create a highly concentrated
dust cloud.
To reduce the risk of accidents and
damage to the power tool, never operate
it with explosive or combustible
materials.
Do not apply sulphur or compounds
containing sulphur since they are highly
explosive and have a very low ignition
point.
To reduce the risk of sparking, explosion
or fire, make sure the discharge system
is completely and properly mounted to
the machine. It consists of a conductive
wire in the spray tube connected to a
metal chain. The metal chain must make
contact with a conductive surface to
dissipate electrostatic charges.
Do not operate your machine on a non-
conductive surface (e.g. plastic,
asphalt).
Never operate your machine with a
missing or damaged discharge system.
