2.10 Dusting and Granulate Spread‐
ing Attachment (Special Acces‐
sory)
Powder or dry granulate can be applied in the
dusting and spreading mode.
Observe legal requirements for handling the
chemicals.
Observe the User Manual or the label of the
plant protection product.
Use
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-conduc‐
tive surface (e.g. plastic, asphalt).
Never operate your machine with a missing or
damaged discharge system.
Follow the mounting instructions supplied with
the "Dusting and Granulate Spreading Attach‐
ment".

2 Safety Precautions and Working Techniques
2.11 Holding and guiding the
machine
Carry the power tool on your back with both har‐
ness straps – do not hang it over one shoulder.
Hold and control the blower tube with your right
hand on the control handle – even if you are left-
handed.
Work only slowly, moving in a forwards direction
– always observe the discharge area of the
blower tube – do not move backwards – risk of
tripping!
Keep the power tool and container upright. To
avoid the risk of chemical leaking from the con‐
tainer and causing injury,do not bend forwards.
2.12 While working
Do not direct the air blast towards bystanders
since the air flow can blow small objects at great
speed.
In the event of impending danger or in an emer‐
gency, switch off the engine immediately by mov‐
ing the setting lever to STOP or 0.
Quickly releasing power tool in an emergency:
– Open the fastener on the hip belt (special
accessory)
– Slip the straps off your shoulders
– Drop the power tool to the ground
Never leave a running machine unattended.
Take special care in slippery conditions – damp‐
ness, snow, ice, on slopes or uneven ground.
