Stihl SG 20 Instruction Manual page 10

Operating instructions
Never spray in the direction of humans,
animals or property which might be
injured or damaged by spray formula.
!
Warning!
Pay attention to the direction of the wind,
i.e., do not work against the wind. When
spraying, stand so that the wind does
not blow towards you or bystanders.
Keep children and pets away from areas
that have just been sprayed. After the
use of some chemicals, especially
agricultural pesticides, a notice must be
posted on the treated area that a
"Restricted Entry Interval" (REI) is in
effect. See the product's label and any
applicable governmental regulations.
Danger!
Your backpack sprayer is
not insulated against
electric shock. To reduce
the risk of electrocution,
never operate this backpack sprayer in
the vicinity of any wires or cables
(power, etc.) which may be carrying
electric current. Do not spray on or near
electrical installations.

After Finishing Work
Always wash thoroughly with soap and
water after spraying or handling
chemicals. Shower immediately, and
wash all protective clothing separately
from other items. Follow any additional
recommendations of the chemical
manufacturer.
Always clean dust and dirt off the
backpack sprayer.
!
Warning!
Empty, rinse and clean the container
and sprayer assembly after each use.
This helps to prevent the solution from
crystallizing, which could later cause
clogging and chemical damage to the
unit. In addition; residual chemicals may
have undesirable effects during
subsequent spraying with a different
type of chemical (e.g., residual herbicide
may damage or kill plants being sprayed
with a pesticide).
Disposal of contaminated rinse should
be in accordance with applicable
ordinances. Observe the precautionary
instructions of the chemical
manufacturer.
Do not store sprayer under pressure or
with spray solution in the container.
