–

damaged or worn straps
Check the condition of the blower housing

–

Wear of the blower housing (cracks, nicks, chips)
may result in an increased risk of injury from
thrown foreign objects. If the blower housing is
damaged, consult your dealer – STIHL recom‐
mends you contact a STIHL servicing dealer

To reduce the risk of accidents and personal
injury, do not operate your power tool if it is not
properly assembled and in good condition.

For emergencies: Practice quickly opening the
fastener on the waist belt (special accessory),
loosening the shoulder straps and setting down
the unit. To avoid damage, do not throw the unit
to the ground when practicing.

2.10 Holding and guiding the machine

Carry the power tool on your back with both har‐
ness straps – do not hang it over one shoulder.
Hold and control the blower tube with your right
hand on the control handle – even if you are left­handed.

Work only slowly, moving in a forwards direction
– always observe the discharge area of the
blower tube – do not move backwards – risk of
tripping!

Keep the power tool and container upright. To
avoid the risk of chemical leaking from the con‐
tainer and causing injury,do not bend forwards.

2.11 While working

2.9 Starting the engine

Start the engine at least 3 meters from the fuel‐
ing spot, outdoors only.

Your power tool is designed to be operated by
one person only. Do not allow other persons in
the work area – even when starting.

Always proceed as described in the user manual.

Place the machine on level ground only, ensure
that you have a secure footing and hold the
machine securely.

If an assistant is required to put the power tool
on your back, make sure that

the engine is running at idle speed

–

the assistant is not standing in the area of the

–

exhaust outlet and breathing exhaust fumes
the valve lever is closed

–

the assistant is not standing in the area of the

–

outlet nozzle
the assistant leaves the work area immedi‐

–

ately after you have put the power tool on your
back

Do not direct the blower tube at bystanders since
the air flow can blow small objects at great
speed.

In the event of impending danger or in an emer‐
gency, switch off the engine immediately by mov‐
ing the setting lever to STOP or 0.

Never leave a running machine unattended.

Take special care in slippery conditions – damp‐
ness, snow, ice, on slopes or uneven ground.

Watch out for obstacles: Be careful of refuse,
tree stumps, roots and ditches which could
cause you to trip or stumble.

Be particularly alert and cautious when wearing
hearing protection because your ability to hear
warnings (shouts, alarms, etc.) is restricted.

2 Safety Precautions and Working Techniques English

Take breaks when you start getting tired or feel‐
ing fatigue – risk of accidents!

Work calmly and carefully – in daylight conditions
and only when visibility is good. Proceed with
caution, do not put others in danger.

Do not work on a ladder or in unstable locations.

When working in open ground and gardens take
special care to avoid harming small animals.

To reduce the risk of electrocution, never operate
this power tool in the vicinity of live wires or
power cables.

Always clean the spray container and hose sys‐
tem before changing to a different plant protec‐
tion product.

As soon as the engine is running, the
power machine generates toxic
exhaust gas. These gases may be
odorless and invisible and may con‐
tain unburned hydrocarbons and ben‐
zene. Never work with the machine in
closed or poorly ventilated rooms.

To reduce the risk of serious or fatal injury from
breathing toxic fumes, ensure proper ventilation
when working in trenches, hollows or other con‐
fined locations.

Stop work immediately if you start suffering from
nausea, headaches, impaired vision (e.g. your
field of vision gets smaller), impaired hearing,
dizziness, or impaired concentration – these
symptoms may possibly be the result of too-high
exhaust gas concentration – Risk of accidents!

Operate your power tool so that it produces a
minimum of noise and emissions – do not run the
engine unnecessarily, accelerate the engine only
when working.

To reduce the risk of fire, do not smoke while
operating or standing near your power tool. Com‐
bustible fuel vapor may escape from the fuel sys‐
tem.

If your power 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 – see also
"Before Starting". Check in particular that the fuel
system has no leaks and the safety equipment is
fully operative. Do not continue operating your
power tool if it is damaged. In case of doubt, con‐
tact a dealer.

2.12 After finishing work

Close the valve lever

Always shut off the engine before taking the
power tool off your back.

After finishing work, put the power tool down on
a level, non-flammable surface. Do not place the
machine near easily flammable materials (e.g.
wood chips, bark, dry grass, fuel) – risk of fire!

Check all parts of the power tool for leaks.

After finishing work, thoroughly clean the power
tool and wash your hands, face and, if neces‐
sary, your clothes.

Keep other persons and animals away from the
areas that have been sprayed and do not walk
on them until the plant protection chemical has
dried.

2.13 Vibrations

Prolonged use of the power tool may result in
vibration-induced circulation problems in the
hands (whitefinger disease).

No general recommendation can be given for the
length of usage because it depends on several
factors.

The period of usage is prolonged by:

Hand protection (wearing warm gloves)

–

Work breaks

–

The period of usage is shortened by:

Any personal tendency to suffer from poor cir‐

–

culation (symptoms: frequently cold fingers,
tingling sensations).
Low outside temperatures.

–

The force with which the handles are held (a

–

tight grip restricts circulation).

Continual and regular users should monitor
closely the condition of their hands and fingers. If
any of the above symptoms appear (e.g. tingling
sensation in fingers), seek medical advice.

2.14 Maintenance and Repairs

Service the machine regularly. Do not attempt
any maintenance or repair work not described in
the instruction manual. Have all other work per‐
formed by a servicing dealer.

STIHL recommends that you have servicing and
repair work carried out exclusively by an author‐
ized STIHL servicing dealer. STIHL dealers are
regularly given the opportunity to attend training
courses and are supplied with the necessary
technical information.

Only use high-quality replacement parts in order
to avoid the risk of accidents and damage to the

respect, consult a servicing dealer.

STIHL recommends the use of genuine STIHL
replacement parts. They are specifically
designed to match your model and meet your
performance requirements.

To reduce the risk of injury, always shut off the
engine before carrying out any maintenance or
repairs or cleaning the machine. – Exception:
Carburetor and idle speed adjustments.

Do not turn the engine over on the starter with
the spark plug boot or spark plug removed since
there is otherwise a risk of fire from uncontained
sparking.

Do not service or store your machine near open
flames.

Check the fuel filler cap for leaks at regular inter‐
vals.

Use only a spark plug of the type approved by
STIHL and make sure it is in good condition –
see "Specifications".

Inspect the ignition lead (insulation in good con‐
dition, secure connection).

Check the condition of the muffler.

To reduce the risk of fire and damage to hearing,
do not operate your machine if the muffler is
damaged or missing.

Do not touch a hot muffler since burn injury will
result.

10.1 During Operation

After a long period of full throttle operation, allow
the engine to run for a short while at idle speed
so that engine heat can be dissipated by the flow
of cooling air. This helps protect engine-mounted

components (ignition, carburetor) from thermal
overload.

10.2 After Finishing Work

Storing for a short period: Wait for the engine to
cool down. Keep the machine in a dry place, well
away from sources of ignition, until you need it
again. For longer out-of-service periods – see
"Storing the Machine".

11 Calculating Required

Quantity of Solution

11.1

In the case of ground crops, simply multiply the
length of the field by its width.

The surface area of high-growing plants is calcu‐
lated approximately by measuring the length of
the rows and the average height of the foliage.
The result is multiplied by the number of rows
and then by two if both sides have to be treated.

The surface area in hectares is obtained by
dividing the number of square meters by 10,000.

Example:

A field 120 meters long and 30 meters wide has
to be treated with a pesticide.

Area:

120 m x 30 m = 3,600 m

3,600 / 10,000 = 0.36 ha

11.2 Determining quantity of active

Refer to the instructions supplied with the active
ingredient to determine:

–

–

Multiply the required quantity of active ingredient
for 1 hectare by the area determined in hectares.
The result is the quantity of active ingredient
required for the area to be treated.

Example:

According to the maker’s instructions, 0.4 liters of
active ingredient are required per hectare to
obtain a concentration of 0.1%.

Quantity of active ingredient:

0.4 (l/ha) x 0.36 (ha) = 0.144 l

K

TW = Quantity of active ingredient in liters

K K = Concentration in %

TB = Required quantity of solution in liters

Example:

The calculated quantity of active ingredient is

0.144 liters. According to the maker’s instruc‐
tions, the concentration is 0.1%.

Quantity of solution:

0.144 l x 100 = 144 l

11.4 Determining walking speed

Carry out a trial run with the machine fueled and
the container filled with water. Operate the spray
tube (swing it back and forth) as for the real run
described below. Determine the distance walked
in one minute.

Also use the trial run to check the selected work‐
ing width. The best working width for low-growing
crops is 4–5 m. Mark the working width with
stakes.

Dividing the distance walked in meters by the
time in minutes gives you the walking speed in
meters per minute (m/min).

Example:

The distance covered in one minute is 10
meters.

Walking speed:

10 m = 10 m/min
1 min

11.5 Determining discharge rate

The setting of the metering unit is calculated as
follows:

Va(l) x vb(m/min) x b(m) = Vc(l/min)

A (m2)

Va = Quantity of solution

vb = Walking speed

Vc = Discharge rate

b = Working width

A = Area

Example:

The values determined above and a working
width of 4 meters require the following setting on
the metering unit:

25.13 Exhaust Emissions

The CO2 value measured in the EU type appro‐
val procedure is specified at

in the product-specific technical data.

The measured CO2 value was determined on a
representative engine in accordance with a

standardized test procedure under laboratory
conditions and does not represent either an
explicit or implied guarantee of the performance
of a specific engine.

The applicable exhaust emission requirements
are fulfilled by the intended usage and mainte‐
nance described in this User Manual. The oper‐
ating license shall be void if the engine is modi‐
fied in any way.
