Safety
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.
• The inside of the muffler contain chemicals that may
be carcinogenic. Avoid contact with these elements
in the event of a damaged muffler.
• 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 a chainsaw you must understand the
effects of kickback and how to avoid them. See
instructions under the heading
What is kickback? on
page 27 .
• 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 30
• Never use a product with visible damage to the
spark plug guard 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.
• Faulty cutting equipment or the wrong combination
of guide bar and saw chain increases the risk of
kickback! Only use the guide bar and saw chain
combinations we recommend, and follow the filing
instructions. See instructions under
Accessories on
page 39
• Never start a chainsaw unless the bar, saw chain
and all covers are fitted correctly. See instructions
under the heading Assembly on page 24 . Without a
bar and saw chain attached to the chainsaw the
clutch can come loose and cause serious injury.
• Do not drop start. This method is very dangerous
because you may lose control of the chainsaw.
• Never start the product indoors. Exhaust fumes can
be dangerous if inhaled.
• 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 over the chainsaw. Never work standing on a
ladder, in a tree or where you do not have a firm
ground to stand on.
(Fig. 13)
• Lack of concentration can lead to kickback if the
kickback zone of the bar accidentally touches a
branch, nearby tree or some other object.

(Fig. 14)
•Never use a chainsaw by holding it with one hand. A
chainsaw is not safely controlled with one hand.
• Always hold the chainsaw 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 chainsaw handles.
This grip minimizes the risk of kickback and lets you
keep the chainsaw under control. Do not let go of the
handles!
(Fig. 15)
• Never use the chainsaw above shoulder height and
try not to cut with the tip of the bar.
(Fig. 16)
• Do not use a chainsaw in a situation where you
cannot call for help in case of an accident.
• Before moving your chainsaw, switch off the engine
and lock the saw chain using the chain brake. Carry
the chainsaw with the bar and chain pointing
backwards. Fit a guard to the bar before transporting
the chain saw or carrying it for any distance.
• When you put the chainsaw 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 chainsaw 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 asphyxiation or
carbon monoxide poisoning.
• It is not possible to cover every conceivable situation
you can face when using a chainsaw. 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 us if you have any
questions about the use of the chainsaw. We will
willingly be of service and provide you with advice as
well as help you to use your chainsaw both efficiently
and safely. Attend a training course in chainsaw
usage if possible. Your dealer, forestry 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 happen when the saw
chain touches the operator. You must use approved
personal protective equipment whenever you use the
machine. Personal protective equipment cannot
eliminate the risk of injury but it will reduce the
degree of injury if an accident does happen. Ask
your servicing dealer for help in choosing the right
equipment.
•Always wear personal protective equipment.
Generally clothes should be close-fitting without
restricting your freedom of movement. Regularly
check the condition of the personal protective
equipment.
• Wear an approved protective helmet.
• Wear approved hearing protection. Long-term
exposure to noise can result in permanent hearing
impairment
• Always wear protective glasses or a face visor to
reduce the risk of injury from thrown objects. A chain
saw is capable of throwing objects, such as wood
chips, small pieces of wood, etc, at great force. This
can result in serious injury, especially to the eyes.
• Wear gloves with saw protection.
• Wear trousers with saw protection.
• Wear boots with saw protection, steel toe-cap and
non-slip sole.
• Always have a first aid kit nearby.
• Sparks can come from the muffler, the bar and chain
or other sources. Always have fire extinguishing
tools and a shovel available to help 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 defective safety devices.
•Do a check of the safety devices regularly. Refer to
Examination, maintenance and service of the
product's safety equipment on page 31 .
• If the safety devices are defective, speak to your
Zenoah servicing dealer.
Chain brake and front hand guard
Your chainsaw is equipped with a chain brake that is
designed to stop the chain if you get a kickback. The
chain brake reduces the risk of accidents, but only you
can prevent them.
(Fig. 17)
WARNING: Avoid situations where there is
a risk of kickback. Take care when using
your chainsaw and make sure the kickback
zone of the bar never touches any object.
(Fig. 18)
The chain brake (A) can either be activated manually (by
your left hand) or automatically by the inertia release
mechanism.
