General safety instructions
WARNING: Read the warning
instructions that follow before you use the
product.
• A chainsaw is a dangerous tool if used carelessly or
incorrectly and can cause serious injury or death. It
is very important that you read and understand the
contents of this operator’s manual.
• Under no circumstances may the design of the
product be modified without the permission of the
manufacturer. Do not use a product that appears
to have been modified by others and only use
accessories recommended for this product. Non-
authorized modifications and/or accessories can
result in serious personal injury or the death of the
operator or others.
• A used muffler/spark arrester and spark arrester
mounting face may contain deposits of combustion
particles that may be carcinogenic. Avoid being
exposed to these compounds when handling the
muffler and/or spark arrester. Prior to any handling of
the muffler and/or the spark arrester, refer to
Muffler
on page 8
.
• Long term inhalation of the engine’s exhaust fumes,
chain oil mist and sawdust can represent a health
risk.
• 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.
• The information in this operator's manual is never
a substitute for professional skills and experience.
If you get into a situation where you feel unsafe,
stop and seek expert advice. Contact your servicing
dealer or an experienced chainsaw user. Do not
attempt any task that you feel unsure of!
Safety instructions for operation
WARNING: Read the warning
instructions that follow before you use the
product.
• Before using the product you must understand the
effects of kickback and how to avoid them. Refer to
Kickback information on page 14
for instructions.
• Never use a product that is faulty.
• Never use a product with visible damage to the
spark plug cap and ignition cable. A risk of sparking
arises, which can cause a fire.
• 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.
• Never start a product unless the guide bar, saw
chain and all covers are fitted correctly. Refer to
Assembly on page 10
for instructions. Without a bar
and saw chain attached to the product the clutch can
come loose and cause serious injury.
• Never start the product indoors. Exhaust fumes can
be dangerous if inhaled.
• The exhaust fumes from the engine are hot and can
contain sparks, which can start a fire. Never start the
product near flammable material!
• Observe your surroundings and make sure that there
is no risk of people or animals coming in contact with
or affect your control of the product.
• 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.
• You must have a steady stance in order to have
full control of the product. Never work standing on
2218 - 004 - 31.08.2023 5
a ladder, in a tree or where you do not have a firm
ground to stand on.
• Working in a tree requires the use of special
cutting and working techniques which must be
observed in order to reduce the increased risk
of personal injury. Never work in a tree unless
you have received specific, professional training for
such work, including training in the use of safety
and other climbing equipment, such as harnesses,
ropes, belts, climbing irons, snap hooks, carabiners,
etcetera.
• Never attempt to catch falling sections. Never cut in
the tree when you are only secured with one rope.
Always use two secured ropes.
• Lack of concentration can lead to kickback if the
kickback zone of the bar accidentally touches a
branch, nearby tree or some other object.
• Never use the product by holding it with one hand.
This product is not safely controlled with one hand.
• Always hold the product with both hands. The right
hand should be on the rear handle, and the left hand
on the front handle. All people, whether right or left
handed, should use this grip. Use a firm grip with
thumbs and fingers encircling the handles. This grip
minimizes the risk of kickback and lets you keep the
product under control. Do not let go of the handles!
• Never use the product above shoulder height.
• Do not use the product in a situation where you
cannot call for help in case of an accident.
• Before moving your product, switch off the engine
and lock the saw chain using the chain brake.
Carry the product with the guide bar and saw chain
pointing backwards. Fit a transportation guard to the
guide bar before transporting the product or carrying
it for any distance.
• When you put the product on the ground, lock the
saw chain using the chain brake and ensure you
have a constant view of the product. Switch the
engine off before leaving your product for any length
of time.
• Sometimes chips get stuck in the clutch cover
causing the saw chain to jam. Always stop the
engine before cleaning.
• Running an engine in a confined or badly ventilated
area can result in death due to carbon monoxide
poisoning.
• The exhaust fumes from the engine are hot and may
contain sparks which can start a fire. Do not start the
product indoors or near flammable material.
• Use the chain brake as a parking brake when
you start the product and when you move short
distances. Always carry the product in the front
handle. This decreases the risk that you or a person
near you get hit by the saw chain.
• 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 colour or condition. These symptoms normally
appear in the fingers, hands or wrists. These
symptoms may be increased in cold temperatures.
• It is not possible to cover every conceivable situation
you can face when using this product. Always
exercise care and use your common sense. Avoid
all situations which you consider to be beyond your
capability. If you still feel uncertain about operating
procedures after reading these instructions, you
should consult an expert before continuing. Do not
hesitate to contact your dealer or Zenoah if you
have any questions about the use of the product.
We will willingly be of service and provide you with
advice as well as help you to use your product
both efficiently and safely. Attend a training course
in chainsaw usage if possible. Your dealer, forestry
62218 - 004 - 31.08.2023
school or your library can provide information about
which training materials and courses are available.
Personal protective equipment
WARNING: Read the warning
instructions that follow before you use the
product.
• Most chainsaw accidents occur when the saw chain
touches the operator. You must use approved
personal protective equipment during operation.
Personal protective equipment does not give you
full protection from injuries but it decreases the
degree of injury if an accident occurs. Speak to your
servicing dealer for recommendations about which
equipment to use.
• Your clothing must be close-fitting but not limit your
movements. Regularly do a check of the condition of
the personal protective equipment.
• Use an approved protective helmet.
• Use approved hearing protection. Long-term
exposure to noise can result in permanent damage
to the hearing.
• Use approved protective glasses or a face visor
to decrease the risk of injury from thrown objects.
The product can throw objects, such as wood chips,
small pieces of wood and more, at large force. This
can result in serious injury, especially to the eyes.
• Use gloves with saw protection.
• Use pants with saw protection.
• Use boots with saw protection, steel toe-cap and
non-slip sole.
• Always have a first-aid kit with you.
• Risk of sparks. Keep fire extinguishing tools and a
shovel near to prevent forest fires.
Safety devices on the product
WARNING: Read the warning
instructions that follow before you use the
product.
• Do not use a product with safety devices that are
damaged or do not operate correctly.
• Do a check of the safety devices regularly. Refer to
Maintenance and checks of the safety devices on
the product on page 24
.
• If the safety devices are damaged or do not operate
correctly, speak to your Zenoah servicing dealer.
Chain brake and front hand guard
Your product has a chain brake that stops the saw chain
if you get a kickback. The chain brake decreases the
risk of accidents, but only you can prevent them.
The chain brake engages (A) manually by your left hand
or automatically by the inertia release mechanism. Push
the front hand guard (B) forward to engage the chain
brake manually.
A
B
Pull the front hand guard rearward to disengage the
chain brake.
Throttle trigger lockout
The throttle trigger lockout prevents accidental operation
of the throttle trigger. If you put your hand around
the handle and press the throttle trigger lockout (A),
it releases the throttle trigger (B). If you release the
handle, the throttle trigger and the throttle trigger lockout
2218 - 004 - 31.08.2023 7
move back to their initial positions. This function locks
the throttle trigger at idle speed.
A
B
Chain catcher
The chain catcher catches the saw chain if it breaks or
derails. Correct saw chain tension and correctly applied
maintenance on the saw chain and guide bar, decrease
the risk of accidents.
Right hand guard
The right hand guard is a protection for your hand on the
rear handle. The right hand guard gives you protection
if the saw chain breaks or derails. The right hand guard
also gives you protection from branches or twigs.
Vibration damping system
The vibration damping system decreases vibration in
the handles. Vibration damping units operate as a
separation between the product body and the handle
unit.
Refer to
Technical data on page 35
for information
about where the vibration damping system is on your
product.
Start/stop switch
Use the start/stop switch to stop the engine.
WARNING: The start/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.
Muffler
WARNING: The muffler becomes very
hot during/after operation and at idle speed.
There is a risk of fire, especially when
you operate the product near flammable
materials and/or fumes.
WARNING: Do not operate a product
without a muffler or with a defective
muffler. A defective muffler can increase
the noise level and the risk of fire. Keep
fire extinguishing tools near. Do not use
a product without, or with a broken, spark
arrestor mesh if you must have a spark
arrestor mesh in your area.
The muffler keeps the noise levels to a minimum and
points the exhaust fumes away from the operator. In
82218 - 004 - 31.08.2023
areas with a hot, dry weather there is a high risk of fire.
Obey local regulations and maintenance instructions.
Fuel safety
WARNING: Read the warning
instructions that follow before you use the
product.
• Make sure there is plenty of ventilation when
refuelling or mixing fuel (petrol and two-stroke oil).
• Fuel and fuel vapour are highly flammable and
can cause serious injury when inhaled or allowed
to come in contact with the skin. For this reason
observe caution when handling fuel and make sure
there is adequate ventilation.
• Take care when handling fuel and chain oil. Be
aware of the risks of fire, explosion and those
associated with inhalation.
• Do not smoke and do not place any hot objects in
the vicinity of fuel.
• Always stop the engine and let it cool for a few
minutes before refuelling.
• When refuelling, open the fuel cap slowly so that any
excess pressure is released gently.
• Tighten the fuel cap carefully after refuelling.

Safety instructions for the cutting
equipment
WARNING: Read the warning
instructions that follow before you use the
product.
• Only use approved guide bar/saw chain
combinations and filing equipment. Refer to
Accessories on page 36
for instructions.
• Use protective gloves when you use or do
maintenance on the saw chain. A saw chain that
does not move can also cause injuries.
• Keep the cutting teeth correctly sharpened. Obey the
instructions and use the recommended file gauge. A
saw chain that is damaged or incorrectly sharpened
increases the risk of accidents.
• Keep the correct depth gauge setting. Obey the
instructions and use the recommended depth gauge
2218 - 004 - 31.08.2023 9
setting. Too large depth gauge setting increases the
risk of kickback.
• Make sure that the saw chain has the correct
tension. If the saw chain is not tight against the
guide bar, the saw chain can derail. An incorrect saw
chain tension increases wear on the guide bar, saw
chain and chain drive sprocket. Refer to
To adjust
the tension of the saw chain on page 30
.
• Do maintenance on the cutting equipment regularly
and keep it correctly lubricated. If the saw chain is
not correctly lubricated, the risk of wear on the guide
bar, saw chain and chain drive sprocket increases.
