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
Wemars service . Avoid all usage which you
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.
• 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
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.
• 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 m while you work. When several operators are
working in the same area the safety distance should
be at least 15 m. 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.
04
• 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.
• 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
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.
• 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 color 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.
• Never use a product with a faulty muffler
• Never start or use the product indoors, near
combustible material or in spaces that lacks proper
ventilation. The exhaust fumes from the engine
contain carbon monoxide, an odorless, poisonous
and highly dangerous gas. Also, the exhaust fumes
are hot and may contain sparks that can start a fire.
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.
05
• 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
bare feet. Put your hair up safely above shoulder
level.
• Keep first aid equipment close at hand.

To do a check of the throttle trigger lockout

that the throttle control (B) is released . When you
release the handle the throttle control and the throttle
trigger lockout both move back to their initial
positions. This movement is controlled by two
independent return springs. This arrangement
means that the throttle control is automatically
locked at the idle setting.
2. Make sure that the throttle control is locked at the
idle setting when the throttle trigger lockout is
released.
3. Press the throttle trigger lockout and make sure that
it returns to its intial position when you release it.

lockout move freely and that the return springs work

without an approved and correctly attached
cutting attachment guard.
WARNING: Always use the recommended
cutting attachment guard for the cutting
attachment that you use. If an incorrect or
faulty cutting attachment guard is fitted this
can cause serious personal injury.
The cutting attachment guard prevents injuries from
objects that eject in the direction of the operator. It also
prevents injuries that occur if you touch the cutting
attachment.

2. Replace the cutting attachment guard if it is
damaged.

odorless, poisonous and highly dangerous
gas.
