Always wear rub-
ber/chemical-resistent
gloves when handling the
backpack sprayer.
For some chemicals it is
advisable to wear imper-
meable coveralls or an
impermeable work apron.
Check the product label.
If you are spraying over-
head or if the spray may
reach head height, wear
a wide brim hat or other
suitable head covering.
Do not wear shorts, san-
dals or go barefoot.
Wear rubber/chemical-
resistent boots.
WARNING
When working with toxic chemicals, the
operator and any bystanders may need
to wear a properly fitted respirator
approved by NIOSH/MSHA for the
chemical being used. Consult the
product label. Breathing toxic chemicals
can cause serious or fatal injury.
WARNING
Backpack sprayers may usually also be
used in greenhouses that are well-
ventilated if the operator can protect
himself or herself from any harmful
4
effects through the use of proper eye,
skin, nose and mouth protection. Such
work may require special precautions.
THE BACKPACK SPRAYER
For illustrations and definitions of the
backpack sprayer parts see the chapter
on "Main Parts and Controls."
WARNING
Never modify this backpack sprayer in
any way. Only attachments supplied by
STIHL or expressly approved by STIHL
for use with the specific STIHL model
are authorized.
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 container system is tight (no leaks)
and that the controls are working
properly. Do not continue operating this
backpack sprayer if it is damaged. In
case of doubt, have it checked by your
STIHL servicing dealer.
WARNING
Make sure the hose is securely attached
and in good condition before
pressurizing the container. Never
attempt to pressurize the unit by any
other method than with the pump
module provided.
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
sprayer.
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. Similarly, the EPA
rates herbicides with the signal words
"Caution", "Warning" and "Danger."
Each category will have unique handling
characteristics. Familiarize yourself with
the characteristics for the category you
are using.
WARNING
Mix only compatible pesticides and/or
herbicides. Wrong mixtures can produce
toxic fumes.
