General safety instructions
WARNING: Read the warning instructions
that follow before you use the product.
• Incorrect or careless use of the product can turn it
into a dangerous tool that can cause serious or even
fatal injury. It is extremely important that you read
1137 - 001 - 24.05.2019 3
and understand the contents of this operator’s
manual.
• This product produces an electromagnetic field
during operation. This field may under some
circumstances interfere with active or passive
medical implants. To reduce the risk of serious or
fatal injury, we recommend persons with medical
implants to consult their physician and the medical
implant manufacturer before operating this product.
• 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.
Such 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. The risk
increases at low temperatures.
• 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.
• Keep in mind that the operator is responsible for
accidents or hazards occurring to other people or
their property.
• Never allow anyone else to use the product without
first ensuring that they have understood the contents
of the operator’s manual.
• Never allow children to use or be in the vicinity of the
product. As the product is equipped with a spring-
loaded 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.
• Store the product out of reach of children.
• Never use the product if you are tired, if you have
drunk alcohol, or if you are taking medication that
could affect your vision, your judgement or your

checks, maintenance and service instructions
described in this manual. Some maintenance and
service measures must be carried out by trained and
qualified specialists. Refer to instructions under the
heading Maintenance.
• Never use a product that has been modified in any
way from its original specification.

service agent.
To do a check of the throttle trigger lockout
1. Make sure that the throttle trigger lockout (A) and
throttle trigger (B) move freely and that the return
spring operates correctly.
AB
2. Push down the throttle trigger lockout and make sure
that it goes back to its initial position when you
release it.
1137 - 001 - 24.05.2019 5
3. Release the throttle trigger lockout and make sure
that the throttle trigger is locked at idle speed
position.
4. Start the engine and apply full throttle.
5. Release the throttle trigger and make sure that the
blades stop fully.
WARNING: If the blades move when the
throttle trigger is in the idle speed
position, adjust the idle speed. Refer to
To adjust the idle speed on page 11
.
To do a check of the stop switch
1. Start the engine.
2. Push the stop switch to the stop position and make
sure that the engine stops.
WARNING: The stop switch automatically
goes back to start position. To prevent
accidental start, remove the spark plug cap
from the spark plug when you assemble or
do maintenance on the product.
To do a check of the hand guard
The hand guard prevents injuries from the blades.
1. Stop the engine.
2. Make sure that the hand guard is attached correctly.
3. Examine the hand guard for damages.
To do a check of the vibration damping system
The vibration damping system decreases vibration in the
handles. The vibration damping units operate as a
separation between the product body and the handle
unit.
1. Do a visual check for deformation and damage.
2. Make sure that the vibration damping units are
correctly attached.
To do a check of the muffler
WARNING: Do not operate the product
without a muffler or a defective muffler. A
defective muffler can increase the noise
level and the risk of fire. Do not use the
product without, or with a broken, spark
arrester screen. The spark arrester screen
must be replaced if it is damaged.
WARNING: The mufflers become very hot
during and after operation, also at idle
speed.
CAUTION: If the spark arrester screen is
frequently blocked it can be a sign that
performance of the catalytic converter is
decreased. Turn to your servicing dealer to
examine the muffler. A blocked spark
arrester screen will cause overheating and
result in damage to the cylinder and piston.
WARNING: The inner surfaces of the muffler
contain chemicals that can cause cancer. Be
careful not to touch these elements if the
muffler is damaged.
The muffler keeps the noise levels to a minimum and
points the exhaust fumes away from the operator. A
muffler with a catalytic converter decrease harmful
exhaust gases.
1. Stop the engine.
2. Do a visual check for damage and deformation.
3. Make sure that the muffler is correctly attached to
the product.
61137 - 001 - 24.05.2019
4. Clean the spark arrester screen with a wire brush.
To do a check of the blade and blade guard
The outer part of the blades (A) has the function as
blade guards. The blade guard protects the operator
from accidental contact with the blade.
A
1. Stop the engine and make sure that the cutting unit
stops.
2. Remove the spark plug cap from the spark plug.
3. Put on protective gloves.
4. Make sure that the blade and blade guard is not
damaged or bent. Always replace a damaged or
bent blade.
5. Make sure that the screws on the cutting unit are
attached. Torque the screws to 7-10 Nm.

Operation
Introduction
WARNING: Read and understand the safety
chapter before you use the product.
Fuel
This product has a two-stroke engine.
CAUTION: Incorrect type of fuel can result in
engine damage. Use a mixture of gasoline
and two-stroke oil.
Premixed fuel
• Use Zenoah premixed alkylate fuel of a good quality,
for best performance and extension of the engine
life. This fuel contains less harmful chemicals
compared to regular fuel, which decreases harmful
exhaust fumes. The quantity of remains after
combustion is lower with this fuel, which keeps the
components of the engine more clean.
To mix fuel
Gasoline
• Use good quality unleaded gasoline with a maximum
of 10% ethanol contents.
CAUTION: Do not use gasoline with an
octane grade less than 90 RON/87 AKI.
Use of a lower octane grade can cause
engine knocking, which causes engine
damages.
• We recommend that you use gasoline of a higher
octane grade for work with continuously high rpm.
Two-stroke oil
• For best results and performance use Zenoah two-
stroke oil.
• If Zenoah two-stroke oil is not available, use a two-
stroke oil of good quality for air-cooled engines.
Speak to your servicing dealer to select the correct
oil.
CAUTION: Do not use two-stroke oil for
water-cooled outboard engines, also
referred to as outboard oil. Do not use oil
for four-stroke engines.
To mix gasoline and two-stroke oil
Gasoline, liter Two-stroke oil,
liter
2% (50:1)
5 0.10
10 0.20
15 0.30
20 0.40
CAUTION: Small errors can influence the
ratio of the mixture drastically when you mix
small quantities of fuel. Measure the quantity
of oil carefully and make sure that you get
the correct mixture.
1. Fill half the quantity of gasoline in a clean container
for fuel.
2. Add the full quantity of oil.
3. Shake the fuel mixture.
4. Add the remaining quantity of gasoline to the
container.
5. Carefully shake the fuel mixture.
CAUTION: Do not mix fuel for more than 1
month at a time.
