Operation Manual

5SG 20
English / USA
For some chemicals it is
advisable to wear
impermeable coveralls or
an impermeable work
apron. Check the product
label. If you are spraying
overhead or if the spray may reach head
height, wear a wide brim hat or other
suitable head covering. Do not wear
shorts, sandals 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
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. 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.
