WARNING

Sprayers may also be used in
greenhouses that are well-ventilated if
the chemical being sprayed allows such
use and 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 SPRAYER

For illustrations and definitions of the
sprayer parts see the chapter on "Main
Parts and Controls."

WARNING

Never modify this 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
sprayer if it is damaged. In case of
doubt, have it checked by your STIHL
servicing dealer.

WARNING

Make sure the lid and pump assembly 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

4

SG 11 , SG 11 PLUS

English

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.

When handling chemicals and when
spraying, make sure you are operating
in accordance with local, state, and
federal environmental protection rules
and guidelines. Do not spray in windy
conditions. To help protect the
environment, use only the
recommended dosage – do not overuse.

WARNING

Do not eat, drink, or smoke while
handling chemicals or while you are
spraying. Never blow through nozzles,
valves, pipes or any other component by
mouth. Always handle chemicals in a
well-ventilated area while wearing
appropriate protective clothing and
safety equipment. Do not store or
transport chemicals with food or
medicines, and never reuse a chemical
container for any other purpose.

Do not transfer spray materials to other
containers, especially food and/or drink
containers.

WARNING

In case of accidental contact or ingestion
of chemicals or in case of contamination
of clothing, stop work and immediately
consult the chemical manufacturer’s
instructions. If in doubt as to what to do,
consult a poison control center or doctor
immediately. Have the product’s label
available to read to or show the persons
you consult.

Clean all chemical spills immediately.
Dispose of any residue in accordance
with state or federal laws and
regulations.

WARNING

Keep chemicals out of reach of children,
other unauthorized people or animals.
When not in use, store chemicals in a
safe place. Follow the manufacturer’s
recommendations for proper storage.

THE USE OF THE SPRAYER

Transporting the Sprayer
Empty container when transporting it in

a vehicle; properly secure it to prevent
damage to the unit.

Filling the Container
Before using the sprayer with chemicals,

fill it with fresh water to assure that you
have it properly assembled; pressurize it
and practice spraying. Also, check for
any leaks at this time. When thoroughly

familiar with the sprayer operation, drain
the water and follow normal operating
procedures.

Fill your sprayer in well-ventilated areas,
outdoors.

WARNING
Do not use:
– flammable substances/materials in

the sprayer, which can explode
causing serious or fatal injury;

– caustic or corrosive materials in the

sprayer, which could result in
damage to the unit and serious or
fatal injuries;

– liquids with a temperature above

30 °C (86 °F) to avoid scalding and
damage to the unit. Do not leave
pressurized sprayer in the hot sun
or near any heat source.

To fill the sprayer, place it on a level
surface. To reduce the risk of
contaminating the surrounding
environment, be careful not to overfill the
container with chemical solution.

If you fill the container with a hose
attached to a central water supply, be
sure the end of the hose is out of the
solution to reduce the risk of backflow,
i.e. the chemicals being sucked into the
water supply in the case of a sudden
vacuum.

Calculate the correct amount of
chemical solution so that it is used up at
one time, with no extra solution left in the
container.

WARNING

To reduce the risk of personal injury
and/or property damage from solutions
that are too strong, make sure that
chemicals that require dilution are
diluted properly. When filled to the
maximum mark, the tank contains
approximately 1.5 l (50.7 oz.). See the
Specifications for the exact amount.

WARNING

Check for leakage while refilling and
during operation. A leak from the
container or a loose fitting could soak
your clothing and come into contact with
your skin.

Before Spraying

WARNING

Always inspect your sprayer before and
after each use. To reduce the risk of
leakage and skin contact with
chemicals, check that the cap is tight,
and in good condition before
pressurizing the container.

WARNING

Never use a sprayer that is damaged or
not properly maintained.

WARNING

Your sprayer is a one-person tool. Do
not allow other persons in the general
work area.

During Operation
Holding and Controlling the Sprayer

The sprayer is operated with either the
right hand or the left hand on the trigger
valve.

WARNING

Keep the container upright to reduce the
risk of spillage.

WARNING

To reduce the risk of injury from loss of
control, never work on a ladder, in a tree
or on any other insecure support.

Working conditions
Operate your sprayer only in a well-

ventilated area. Operate it under good
visibility and daylight conditions only.
Work carefully.

WARNING

Inhalation of certain chemicals can
cause susceptible persons to have an
allergic or asthmatic reaction.

Substantial or repeated inhalation of
certain chemicals may cause respiratory
disease, cancer, birth defects, or other
reproductive harm. Control the chemical
spray at the source where possible. Use

good work practices, such as operating
the unit so that the wind or operating
process does not blow the spray back on
the operator. Follow the
recommendations of
EPA/OSHA/NIOSH and occupational
and trade associations with respect to
proper usage. When the inhalation of the
chemical being sprayed cannot be
avoided, the operator and any
bystanders may need to wear a
respirator approved by NIOSH/MSHA
for the type of chemical encountered.
Consult the label of the chemical product
being used.

WARNING
If you are unfamiliar with the risks

associated with the particular chemical
at issue, review the product label and/or
material safety data sheet for that
substance and/or consult the material
manufacturer/supplier. You may also
consult your employer, governmental
agencies such as the EPA, OSHA and
NIOSH and other sources on hazardous
materials. The state of California and
some other authorities, for instance,
have published lists of substances
known to cause cancer, reproductive
toxicity, etc.

Operating Instructions

WARNING
Never spray in the direction of humans,

animals or property which might be
injured or damaged by spray formula.

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.

6

SG 11 , SG 11 PLUS

English

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

To reduce the risk of
electrocution, never oper­ate this sprayer in the
vicinity of any wires or
cables (power, etc.)
which may be carrying
electric current. Do not
spray on or near electri­cal systems.

WARNING

To reduce the risk of injury, always
release pressure in the container prior to
filling, cleaning or servicing the sprayer
and when spraying is completed. Pull up
on the pressure release valve while
holding the unit in an upright position.

After Finishing Work
Always release the pressure out of the

container after finishing work. To release
the pressure, turn the knurled wheel on
the pressure relief valve while holding
the unit upright until there is no more air
or mist coming out. Open the cover
slowly to make sure that the container is
completely depressurized. Avoid
breathing in the mist which is released.

Always wash thoroughly with soap and
water after spraying or handling
chemicals. Shower immediately, and

wash all protective clothing separately.
Follow any additional recommendations
of the chemical manufacturer.

Always clean dust and dirt off the
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.
