• Chainsaws and hedge trimmers are potentially
dangerous tools. Professional training is
recommended before first use.
• If you are not familiar with chainsaws and their
use, it is recommended that you obtain further
more detailed instructions and information
regarding chain-sawing in addition to reading
these instructions fully. We also recommend that
inexperienced chainsaw users practice cutting
logs on a saw-horse or log cradle before
attempting to prune a tree.
• Keep work area clean.
• Do OT start cutting until you have a clear work
area, secure footing and a planned, clear escape
path from the falling tree or limb.
• Use extreme caution when cutting small size
brush and saplings because the slender material
may catch the saw chain and be whipped toward
you or pull you off balance.
• Do OT operate a chainsaw at height in a tree
or on a ladder unless specifically trained to do so.
• When cutting a limb that is under tension, be
alert for spring back so that you will not be
struck when the tension in the wood fibres is
released.
• Do OT expose the unit to rain.
• Do OT use the unit in damp or wet conditions.
• Do OT use the unit in presence of flammable
liquids or gases.
• Keep children, bystanders and pets away from
the work area.
• When not in use, item should be stored in a dry,
secure location – well out of the reach of
children.
• Always fit the chain guard when not in use.
• Never force the chainsaw or hedge trimmer - it will do
the job better and safer when used correctly.
• Do OT use for cutting plastic, masonry, non-wood
building materials.
• Do OT use the unit for any use other than those
described in these instructions.
• Make sure you are suitably dressed with correct
standard Personal Protective Equipment.
• Do OT wear loose clothing or jewellery that can get
caught in moving parts. Heavy duty gloves and sturdy
non-slip work boots are recommended when working
outdoors.
• Wear a hairnet to contain long hair which can get
caught in moving parts.
• Always wear suitable head, ear and eye protection.
• Carry with the engine stopped, your finger off the
trigger and the guide bar and saw chain or hedge
trimmer to your rear.
• Periodically inspect chainsaw for damage. Do OT use
if damaged in any way.
• Always clean after use and replace worn parts when
performance becomes reduced.
• Do OT smoke while handling fuel or while operating
the item.
• Follow instructions for lubricating and changing
accessories.
• Keep handles dry, clean and free from oil and grease.
• Turn off the unit when not in use, before servicing or
cleaning, and when changing accessories and
attachments.
• Stay alert, watch what you are doing. Always use
common sense.

time.
• When servicing, use only identical replacement
parts.
• Do OT use the unit if the switch does not turn it
on and off.
• Do OT operate a chainsaw that is damaged,
improperly adjusted, or is not completely and
securely assembled. Be sure that the saw chain
stops moving when the trigger is released before
using to cut wood.
• uard against kickback.
• Only use replacement parts specified by the
manufacturer or the equivalent.
• For outdoor domestic use only.
Warnings for safe operation
!
RESIDUAL RISKS
Despite the above warnings and due to the nature of
the product, there remains a residual risk, which
cannot be prevented when using this unit. The
following potential hazards might apply:
• Contact with exposed saw teeth of the saw chain or
hedge trimmer blades (cutting hazards).
• Access to the rotating saw chain or hedge trimmer
blades (cutting hazards).
• Unforeseen, abrupt movement of the guide bar or
hedge trimmer blades (cutting hazards.)
• Parts flung out from the saw chain or hedge trimmer
blades (cutting/injection hazards).
• Wood splinter ejection.
• Inhalation of wood particles and dust - there may
be health risks caused by breathing in dust,
especially dust generated from sawing oak, beech
and MDF.
• Skin contact with the lubricating oil.
• Loss of hearing, if ear protection is not worn.
I TE DED/U I TE DED USE
When using the unit, the user must arrange to use
personal protective equipment according to the
instructions. Parts of the intended use are detailed in
the instructions safety warnings and references for use
by those who work with the chain saw or maintain it,
therefore the user must be familiar with the
instructions. Only use original or approved spare parts
(e.g. guide bar; saw chain).

12
Warnings for safe operation
!
Vibration Warning!
Prolonged use of chainsaws or hedge trimmers or any
other machine that vibrates in use, may produce a
medical condition called “white finger disease”,
“Raynaud’s phenomenon”, or “carpal tunnel
syndrome”. These conditions can cause numbness,
burning sensations and circulation damage, and may
reduce the hand’s ability to feel and regulate
temperature.
The factors that contribute to these conditions are
not fully known, but high vibrations may be a cause.
Users should take precautions to minimise the risks
which include:
• Wear gloves
• Keep hands warm
• Take breaks from prolonged use
• Keep the chain saw sharp so that it operates as
smoothly as possible
• Maintain a firm grip but do not squeeze too tight
and for too long at any one time. Continual and
regular users should monitor their hands and
fingers and if any symptoms occur, or if you are
worried at any time, cease use and consult your
medical practitioner for further advice.
Warning! Restriction of use.
Please check with your local authority before using a
chainsaw as there may be regulations in force that
restrict their use e.g. in times of drought.
Warning! Hearing protection.
It is recommended that safety ear/hearing protection
is worn at all times when operating this unit. Engine
noise may damage your hearing. Regular users should
have frequent hearing tests with their medical
practitioner. The hearing protection should be suitable
for defending hearing for the following levels:
Sound pressure level according to ISO22868
LPA:108dB(A).
Sound power level according to ISO22868 LWA:
<114dB
Inhalation Warning!
Using the unit may generate dust, mist and fumes
containing chemicals that could be harmful to the
user. Dust alone may also be harmful and should not
be inhaled. Never use the unit to cut anything that is
known to contain a harmful substance such as
asbestos. Always operate the unit in a well-ventilated
location, preferably outdoors. Remember that the fuel
and oil used to power and lubricate this machine will
give off harmful fumes in use, and when filling –
always ensure there is sufficient ventilation as soon as
you start the engine. A dust mask or breathing
apparatus is recommended safety equipment, and
anyone with a respiratory or other breathing medical
condition is advised to consult their medical
practitioner before using the chainsaw.

OTE
1. When restarting the engine immediately after stopping it, leave the
choke open.
2. Overchoking can make the engine hard to start due to excess fuel. If
the engine fails to start after several attempts, open the choke and
repeat pulling the recoil starter cable, or remove the spark plug and
dry it.
STOPPI G THE E GI E
1. Press the ignition switch to the OFF position.
ADJUSTI G IDLI G SPEED
1. When the engine tends to stop frequently at idling mode or the
engine works but the blades or saw fail to work, turn the adjusting
screw clockwise a quarter turn and repeat if necessary. Do this on a
warm engine.
2. When the cutting head keeps rotating after releasing the trigger, turn
the adjusting screw anti-clockwise.
(A) Idle adjusting screw
OTE
Warm up the engine before adjusting the idling speed.
TROUBLESHOOTI G - starting the engine
If the choke is left in the ‘START’ position continuously it will prevent
the engine from starting because there is too much fuel for the air
being provided (the choke control reduces the air provided being burnt
with the fuel).
On warm days, a 2-stroke engine does not need to be choked very
much. The cooler it is, the longer you will need to leave the choke on.
Pull the recoil starter cable 3 to 4 times to start the engine, this should
provide a sufficient fuel/air mixture to the cylinder head. When the
engine starts, put the choke lever back to the ‘RUN’ position after a

choke back to the ‘START’ position for a minute or two. If it doesn’t

more times. Then apply the choke and try to start. If it still does not
start remove the spark plug clean/dry, replace and start again.
