fatal injury, we recommend persons with medical
implants to consult their physician and the medical
implant manufacturer before operating this product.
Safety instructions for operation
WARNING: Read the warning instructions
that follow before you use the product.
• You must understand the difference between grass
clearing and grass trimming before use.
• If you encounter a situation where you are uncertain
how to proceed you should ask an expert. Contact
your dealer or your service workshop. Avoid all
usage which you consider to be beyond your
capability.
• Never use a product that is faulty. Carry out the
safety checks, maintenance and service instructions
described in this manual. Some maintenance and
service measures must be carried out by trained and
qualified specialists. See instructions under
Maintenance on page 19
• All covers, guards and handles must be fitted before
you start the product. Ensure that the spark plug cap
and ignition lead are undamaged to avoid the risk of
electric shock.
• Never use the product if you are fatigued, while
under the influence of alcohol or drugs, medication
353 - 003 - 06.01.2018 5

or anything that could affect your vision, alertness,
coordination or judgement.
• Do not use the product in bad weather such as
dense fog, heavy rain, strong wind, intense cold,
etcetera. Working in bad weather is tiring and often
brings added risks, such as icy ground,
unpredictable felling direction, etcetera.
• The only accessories you can operate with this
engine unit are the cutting attachments that we
recommend in the chapter
# .
• Never allow children to use or be in the vicinity of the
product. As the product is equipped with a spring-
loaded start/stop switch and can be started by low
speed and force on the starter handle, even small
children under some circumstances can produce the
force necessary to start the product. This can mean
a risk of serious personal injury. Therefore remove
the spark plug cap when the product is not under
close supervision.
• Running an engine in a confined or badly ventilated
area can result in death due to asphyxiation or
carbon monoxide poisoning.
• The complete clutch cover and shaft must be fitted
before the product is started, otherwise the clutch
can come loose and cause personal injury.
• Ensure that no people or animals come closer than
15 metres while you work. When several operators
are working in the same area the safety distance
should be at least 15 metres. Otherwise there is a
risk of serious personal injury. Stop the product
immediately if anyone approaches. Never swing the
product around without first checking behind you to
make sure that noone is within the safety zone.
• Ensure that people, animals or other things can not
affect your control of the product or that they do not
come in contact with the cutting attachment or loose
objects that are thrown out by the cutting
attachment. However, do not the product unless you
are able to call for help in the event of an accident.
• Always inspect the working area. Remove all loose
objects such as stones, broken glass, nails, steel
wire, string, etcetera, that could be thrown out or
become wrapped around the cutting attachment.
• Make sure that you can move and stand safely.
Check the area around you for possible obstacles
(roots, rocks, branches, ditches, etcetera) in case
you have to move suddenly. Take great care when
you work on sloping ground.
• Keep a good balance and a firm foothold at all times.
Do not overreach.
• Always hold the product with both hands. Hold the
product on the right side of your body.
• Make sure that you attach the harness to the
suspension ring.
• Keep the cutting attachment below waist level.
• Switch off the engine before you move to another
area. Fit the transportation guard before you carry or
transport the equipment any distance.
• Never put the product down with the engine running
unless you have it in clear sight.
• Stop the engine and cutting equipment before you
remove material that has wound around the blade
shaft. Neither the operator of the product nor anyone
else may attempt to remove the cut material while
the engine is running or the cutting equipment is
rotating, as this can result in serious injury. The
bevel gear can get hot during use and may remain
so for a while afterwards. You could get burnt if you
touch it.
• Watch out for thrown objects. Always wear approved
eye protection. Never lean over the cutting
attachment guard. Stones, rubbish, etcetera, can be
6353 - 003 - 06.01.2018

thrown up into the eyes which can cause blindness
or serious injury.
• Sometimes branches or grass get caught between
the guard and cutting attachment. Always stop the
engine before you clean the product.
• Products that are fitted with saw blades or grass
blades can be thrown violently to the side when the
blade comes into contact with a fired object. This is
called blade thrust. A blade thrust can be violent
enough to cause the product and/or operator to be
propelled in any direction, and possibly lose control
of the product. Blade thrust can occur without
warning if the product snags, stalls or binds. Blade
thrust is more likely to occur in areas where it is
difficult to see the material being cut.
• Avoid to cut with the area of the blade between the
12 o'clock and 3 o'clock positions. Because of the
speed of rotation of the blade, blade thrust can occur
if you attempt to cut thick stems with this area of the
blade.
• Always slow the engine to idle speed after each
working operation. Long periods at full throttle
without any load on the engine can lead to serious
engine damage.
• Listen out for warning signals or shouts when you
wear hearing protection. Always remove your
hearing protection as soon as the engine stops.
• Overexposure to vibration can lead to circulatory
damage or nerve damage in people who have
impaired circulation. Contact your doctor if you
experience symptoms of overexposure to vibration.
These symptoms include numbness, loss of feeling,
tingling, pricking, pain, loss of strength, changes in
skin colour or condition. These symptoms normally
appear in the fingers, hands or wrists.
• Do not use a product with a damaged spark plug
cap.
• Do not use a product with a defective muffler.
• Keep all parts of your body away from the rotating
cutting attachment and hot surfaces.
• Always wear gloves when you handle the grass
blade.
Personal protective equipment
WARNING: Read the warning instructions
that follow before you use the product.
• Always use approved personal protective equipment
when you use the product. Personal protective
equipment cannot fully prevent injury but it
decreases the degree of injury if an accident does
occur. Let your dealer help you select the right
equipment.
• Use a protective helmet where there is a risk of
falling objects.
• Use approved hearing protection that provides
adequate noise reduction. Long-term exposure to
noise can result in permanent hearing impairment.
• Use approved eye protection. If you use a visor, you
must also use approved protective goggles.
Approved protective goggles must comply with the
ANSI Z87.1 standard in the USAs or EN 166 in EU
countries.
• Use gloves when necessary, for example when you
attach, examine or clean the cutting equipment.
• Use protective boots with steel toes and non-slip
soles.
• Use clothing made of a strong fabric. Always use
heavy, long pants and long sleeves. Do not use
loose clothing that can catch on twigs and branches.
Do not wear jewelry, short pants, sandals or go with
353 - 003 - 06.01.2018 7

bare feet. Put your hair up safely above shoulder
level.
• Keep first aid equipment close at hand.

Grass clearing with a grass blade
WARNING: Do not use grass blades and
grass knifes on woody steams.
The grass blade is used for all types of coarse grass.
You can decrease the risk of material wrapping around
the blade by:
• Always work with full throttle.
• Avoid previously cut material during the return
stroke.
To clear grass with a grass blade
1. Stand firmly with your feet apart.
2. Let the support cup rest lightly against the ground.
Do this to protect the blade from hitting the ground.
3. Use a sideway swing movement from right to left to
use the clear stroke and let the left side of the blade
(between 8 and 12 o'clock) do the cutting.
4. Angle the the blade to the left when you clear grass.
Note: The grass will collect in a line, which makes it
easier to collect.
5. Use a sideway swing movement from left to right for
the return stroke.
6. Do the work rhythmically.
7. Move forward and stand firmly again.
8. Stop the engine.
9. Remove the product from the clip on the harness.
10. Put the product on the ground.

Grass trimming with a trimmer head
To use the grass trimming technique
• Keep the trimmer head near the ground at an angle.
The grass is cut by the end of the trimmer line.
• Move the trimmer line slowly into the area to be cut,
do not force it.
• Use this procedure to cut grass against for example
walls, fences and trees.
CAUTION: The trimmer line can do
damage to sensitive trees, bushes and
fences. To prevent this, decrease the
length of the trimmer line to 10–12 cm
and decrease the engine speed.
To use the grass clearing technique
• Use this procedure to fully remove the grass.
• Keep the trimmer head near the ground at an angle.
Let the trimmer line hit the ground around the object
where you remove the grass.
CAUTION: This procedure increases the
wear on the trimmer line. It is necessary
to increase the length of the trimmer line
more frequently when you clear grass
against stones, concrete and metal
fences than against trees and fences
made of wood.
• Decrease the engine speed to decrease the wear on
the trimmer line and the trimmer head.
18 353 - 003 - 06.01.2018

To use the cutting technique
• Use this procedure to cut grass where you cannot
use a lawn mower.
• Keep the trimmer head parallel to the ground.
CAUTION: Do not press the trimmer
head against the ground and do not let it
touch the ground frequently. This can do
damage to the lawn and the trimmer
head.
To use the sweeping technique
• The airflow from the rotating trimmer line can be
used to remove cut grass from an area.
• For best results, apply full throttle.
• Keep the trimmer line parallel to and above the
ground, and move the trimmer head from side to
side.
• Clean the trimmer head cover every time you refill
the cord to avoid unbalance and vibrations in the
handles. Also do a check of the other parts of the
trimmer head and clean it if necessary.

Spark plug
CAUTION: Always use the recommended
spark plug type! Use of the wrong spark plug
can damage the piston/cylinder. Check that
the spark plug is fitted with a suppressor.
The condition of the spark plug is influensed by
• Incorrect carburettor adjustment.
• An incorrect fuel mixture (To much or incorrect type
of oil).
• A dirty air filter.
These factors cause deposits on the spark plug
electrodes which may result in operating problems and
starting difficulties.
Always check the spark plug first If the product is low on
power, difficult to start or runs poorly at idle speed. If the
spark plug is dirty, clean it and check the electrode gap.
Replace the spark plug after a month of operation or
erlier if it is necesarry.
