THE POWER TOOL
For illustrations and definitions of the
power tool parts see the chapter on
“Main Parts and Controls.”
!Warning!
Never modify this power tool in any way.
Only attachments supplied by STIHL or
expressly approved by STIHL for use
with the specific STIHL model are
authorized. Although certain
unauthorized attachments are useable
with STIHL power tools, their use may, in
fact, be extremely dangerous.
If this tool is subjected to unusually high
loads for which it was not designed (e.g.
heavy impact or a fall), always check
that it is in good condition before
continuing work. Check in particular that
the fuel system is tight (no leaks) and
that the controls and safety devices are
working properly. Do not continue
operating this machine if it is damaged.
In case of doubt, have it checked by your
STIHL servicing dealer.
!Warning!
An electrostatic charge may be created
in the extension tube and nozzle area
when applying dry materials (e.g. dusts)
with the dusting and spreading
attachment (special accessory). This is
especially true in low humidity
conditions. Check the label and/or
material safety data sheet for the
chemical you are applying. To reduce
the risk of severe or fatal injury, do not
use your mistblower to apply substances
that may create a combustible or
explosive dust cloud. For instance,
never use your mistblower to apply
sulfur or sulfur compounds, since they
may be highly explosive and have
relatively low melting and ignition points.
!Warning!
To reduce the risk of sparking when
applying any dry substance, make sure
that the discharge system (conductive
wire in the mistblower connected to a
metal chain) is completely and properly
mounted to the machine, and that the
discharge chain is making contact with
the ground. It is essential to follow the
fitting instructions supplied with the
dusting and spreading attachment.
HANDLING OF CHEMICALS
!Warning!
Chemicals can be harmful to individuals,
animals and the environment if
improperly used. In addition, some
chemicals that are caustic, corrosive or
poisonous should not be used in your
mistblowers.
Carefully read the labels on chemical
containers prior to use. Chemicals are
classified into categories of toxicity.
Pesticides regulated by the EPA, for
instance, use signal words to indicate
the product’s potential to make you sick.
“Caution“ appears on pesticides found to
be least harmful to humans. “Warning“
indicates a product that is more
poisonous than those in the “Caution“
group. Pesticides with the signal word
“Danger“ on the label are very
poisonous or irritating. They should be
used with extreme care. Finally,
pesticides labeled “Danger – Poison“
are for restricted use only and generally
must be used under the supervision of a
certified applicator. Each category will
have unique handling characteristics.
Familiarize yourself with the
characteristics for the category you are
using.
!Warning!
Mix only compatible pesticides. Wrong
mixtures can produce toxic fumes.
