•Follow the instructions for lubrication, tension and chain change accessories. A chain
whose tension and lubrication are incorrect can either break or increase the risk of
rebound.
•Keep handles dry, clean and free of oil and grease. Oily, greasy grips are slippery and
cause loss of control.
•Cut only wood, as well as for pruning and cutting wood. Do not use the chain saw for any
other purpose. For example: do not use it to cut plastic, masonry or construction materials
other than wood. Using the chain saw for operations other than those specified may result
in hazardous situations.
•Be careful when using the machine during stormy weather. Do not use the machine

and saw dust; avoid to be exposed to these and wear protective equipment.
•Wear protective gloves when assembly, disassembly, sharpening chain tensioning and
when handling the guide bar.
•Guide-bar and chain adjustments shall be perform with the engine stopped.
•Regularly check and test the chain brake.
•Hazards may be encountered while using the saw, such as blockage of the saw chain. In
order to reduce hazards, follow the instruction for cutting operation; always check the
condition of the tool. Do not start the chainsaw directly in a tree.
Fuel Handling
•Be very careful when handling fuels. They are flammable and the vapors are explosive.
•Use only an approved container.
•Never remove the fuel cap or add fuel while the machine is on. Turn off the unit and allow
the engine and exhaust components to cool before refueling.
•Do not smoke.
•Never refuel inside a room
•Never store the tool and the fuel tray indoors where there is a naked flame, such as near
a water heater.
•If fuel has spilled, do not attempt to start the machine, but rather move it away from the
spill before starting to use it. Clean any spills.
•Replace and tighten the fuel tank cap after refueling.
•Follow the instructions in this manual for filling the tool with fuel.
During maintenance and storage
•Stop the tool and wait until it stops. Make sure all moving parts have come to a standstill.
•Allow the machine to cool before performing inspection, adjustments, maintenance,
servicing and storage.
•Store the tool where fuel vapor will not reach a flame or spark.
•When transporting and storing, always place the tool in its transport guard and protective
device on it.
Causes of rebounds and prevention by the operator
•Bounce may occur when the spout or end of the chain guide touches an object, or when
the wood tightens and pinches the cutting chain in the cutting section.
•The contact of the tip may in some cases cause a sudden reverse reaction by bouncing
the chain guide up and back towards the operator.
•Pinching of the cutting chain on the upper part of the chain guide can force the chain
guide to the operator abruptly.
•Either of these reactions can result in loss of control of the saw likely to result in a serious
personal injury. Do not rely exclusively on safety devices built into your saw. As a chain
saw user, all measures should be taken to eliminate the risk of accident or injury during
cutting.

6
•Bounce results from improper use of the tool and / or incorrect operating procedures or
conditions and can be avoided by taking the appropriate precautions specified below:
•Hold the saw with both hands firmly with the thumbs and fingers encircling the handles of
the saw and place your body and arms to allow you to withstand the rebound forces. The
rebound forces can be controlled by the operator, if appropriate precautions are taken. Do
not allow chain saw to start.
•Do not stretch the arm too far and do not cut above the shoulder height. This helps
prevent unintentional end contacts and allows better control of the chain saw in
unforeseen situations.
•Use only the manufacturers specified replacement guides and chains. Incorrect
replacement guides and chains may cause chain breakage and / or rebound.
•Follow manufacturer's instructions for sharpening and servicing the chain saw. A
decrease in the depth gauge level can lead to an increase in rebounds.

4. FILLING THE FUEL TANK
WARNING: When filling the tank:
The chainsaw must always be stopped and cooled.
Never smoke during refueling. It must not have flames or sparks near the fuel.
Before refueling, allow the chainsaw to cool completely. Do not attempt to refuel when
the engine is hot.
If fuel has been spilled, immediately stop refueling and do not start the engine. Clean
up the spill and fill the machine in another location
Never fill the fuel tank to the flange; there is a risk of overflow.
Do not refuel in a closed and unventilated area.
The fuel used for this tool is a mixture of unleaded gasoline and registered engine lubricant.
When mixing gasoline with oil, use only gasoline that does not contain ethanol or methanol.
Unleaded gasoline is a quality gasoline type. This will help to avoid damaging the fuel lines of
the engine and other engine parts.
The recommended mixing ratio is 40:1 (make sure the mixing ratio is correct before filling the
product.
a. Mixing ▪Mix in a clean, empty container (supplied).
▪Pour the oil into the container.
▪Pour the fuel into the tank. Mix the mixture long enough (more than one
minute) to get a good combination.
b. Filling the fuel tank
▪Unscrew the fuel tank cap and remove it.
▪Fill the tank slowly with the mixture. Do not exceed the maximum capacity (fill to 80%
of its capacity preferably).
▪Replace the cap on the fuel tank and tighten it
▪Wipe any spillage around the unit if necessary
Note: To avoid damage and accidents, DO NOT USE OTHER MIXTURES AND OTHER
TYPES OF OIL / PETROL
c. Storage of fuel
The fuel must be kept in a clean and safe container and always closed.
If you are not using the product for a long time, remove the fuel mixture and add it to a
container.
Do not leave the fuel for a long time in the product. The fuel may clog the carburetor and
the engine will not operate properly.
d. Disposal of fuel
When the fuel is no longer used or worn, please dispose of it in an authorized location.
Check local laws regarding disposal of fuels

13
5. OPERATION
Before using the chainsaw, inspect the work area. This must be cleared. Remove any
branches, obstacles and other items that may cause damage during cutting.
The unit should always be filled with fuel and useful. Check the level of filling and refill when
necessary.
IMPORTANT: starting shall always be done with the chain brake activated. See on page
14 and 15 how to achieve this.
1. Starting the engine
a. Press the priming pump continuously until the fuel enters the pump. Set the switch to
position I.
b. Pull the starter button. The starter will close and the throttle will be moved to the
starting position
Hold the chainsaw firmly against the ground. Put the chainsaw:
▪Either on the left side of your body holding the handle firmly with your left
hand. Use your right hand to pull the starter rope
▪Either on the right side of your body holding the handle firmly with your right
hand.
Use your left hand to pull on the starter rope.
In both cases, the saw must remain away from the operator's body.

14
2. Stopping the engine
Allow the chainsaw to run for a few minutes. Then turn the switch to the OFF position.
3. Main settings
a. Adjusting the carburetor
The carburetor is preset at the factory. To avoid malfunction, it is recommended not
to adjust the adjustment screws. If these screws require readjustment, have the
machine serviced by your service center.
Stop the tool and tighten the needle L until it stops. Do not force it. Then set it to its
initial number of turns as shown below. The number of turns for the needle is also
shown below:
b. Chain brake
The chain brake is a device that automatically stops the chain in case a backward
movement occurs, causing the saw to jump. Normally, the brake is automatically
activated by the inertia force.
It is also manually tightened by pushing the brake lever down and forward.
When the brake is running, a yellow sign comes out from the base of the brake lever.
To release the brake, pull the brake lever up until it clicks into place.
When the brake is working, release the throttle lever to slow down the engine speed.
Continuous use when the brake is running causes the clutch to heat up and can
cause problems.
When checking the machine before using it, check the operating condition of the
brake by performing the following operations:
▪Start the engine and grasp the handle firmly with both hands.
▪While pulling the throttle control lever to keep the chain in operation, push
the brake lever down with the back of the left hand.
▪When the brake is running and the chain is stopped, remove the hand from
the throttle.
▪Loosen the brake.

15
c. Release of the chain brake
To use the chain saw again, the chain brake must be released. This must be done
machine off and cooled. Pull the shield until it returns to its original position.
d. Sharpening of the chain
For best performance, we strongly recommend that you periodically sharpen the
chain. The chain can either be sharpened by a professional or by yourself by
providing you with a sharpening guide (make sure you know how to use it).
The chain must be sharpened when:
- Wood chips have become powder
- To make a normal cut, force on the tool
- The cut is not straight
- Vibration increases
- Fuel consumption has increased
e. Checking the lubrication of the chain
- Before checking the oil, make sure that the bar and the chain are in place.
- Once the engine is started, turns it at medium speed and checks that the chain
oil is sprayed and traces off the ground.
- The oil flow of the chain is adjustable to obtain the proper flow. Insert a
screwdriver on the clutch side.
- Turn the adjuster to obtain the correct flow rate for the job.
- The chainsaw must essentially consume the contents of the oil tank between
each full of fuel. Do not forget to fill the oil tank when filling the machine with
fuel.
4. Work with wire and harness
NOTE: It is necessary to have a complete training before working at high. It is
strongly recommended that only experienced and trained persons carry out work
at high. Know all emergency procedures to be carried out.
These instructions are examples of good practice. Follow and abide by local laws and
regulations as well.
It is also recommended that the operator who is going to work at height be assisted by
another person.
It is compulsory with techniques of climbing and working position. Be equipped with
complete equipment including harnesses, ropes, strops, snap hooks and other equipment
that allows them to maintain and maintain the saw by adopting secure positions.

16
a. Using the Chainsaw in the Tree
An analysis of accidents with chainsaws during tree pruning shows that the main
cause is an inadequate use of the one-hand chainsaw. In a large majority of
accidents, operators do not seek to adopt a safe working position that allows them to
hold with both hands. This results in an increased risk of injury due to:
-The absence of a firm grasp of the chainsaw in case of rebound
-A lack of control of the chainsaw, which is more likely to come into contact with
the climbing ropes and with the operator's body (especially the hand and the left
arm) and
-Loss of control due to unsafe working position, resulting in contact with the
chain saw (unexpected movement during operation of the chain saw).
b. Safe positioning for two-hand operation
In order to allow operators to hold the chain saw with both hands, it is generally
recommended that they aim for a safe working position when operating the chain saw:
-At the hip, when cutting horizontal sections, and
-At the level of solar plexus, when cutting vertical sections.
When operators work near vertical trunks with low lateral forces on their working
position, good support may be sufficient to maintain a safe working position. However,
as operators move away from the trunk, they will need to take steps to suppress or
neutralize increasing lateral forces, for example by redirecting the main rope through an
additional anchor point or using an adjustable strap directly from the harness Has an
additional anchor point.
The obtaining of a good support to the working position can be favored by the use of a
foot stirrup created by an endless sling.

17
c. Starting the saw in the tree
When starting the saw in the shaft, the operator should:
-Apply the chain brake before starting, and
-Hold the saw on the left side, either on the right side before starting:
▪On the left side, hold the saw with your left hand on the front handle while
holding the saw away from the body while pulling the starter rope with your
right hand, or
▪On the right side, hold the saw with your right hand on one of the two
handles while holding the saw away from the body while pulling the starter
rope with your left hand.
-The chain brake should always be engaged before lowering a running saw to its
stroke.
-Operators should always check that the saw has sufficient fuel before
undertaking critical cuts.
d. Using the chain saw with one hand
Operators should not use chain saws to prune single-handed trees when they are in
an unstable working position and prefer hand saws when cutting wood of small
diameter at the ends of the branches.
Only chainsaws should be used for tree pruning with one hand when:
-Operators cannot maintain a working position allowing them to use both hands
-They need to maintain their working position, allowing them to use both hands
-The saw is used in full extension, perpendicular to the body of the operator and
separated from it.

18
Operators should:
-Never cut with the rebound area at the end of the chain saw chain guide
-Never hold and cut sections or
-Never try to catch sections when they fall.
e. Release of a jammed saw
If the saw gets stuck during cutting, the operators should:
-Saw the saw and attach it securely to the cutting foot of the shaft (ie trunk side)
or has a separate chord from the tool
-Pull the saw of the cluster while the branch is lifted, if necessary,
-If necessary, use a hand saw or a second chainsaw to release the chain saw.
5. Cutting work
The tool should only be used to cut trees. Do not use it for other applications.
Do not attempt to remove the chainsaw when it is stuck during operation. Stop the
machine and remove the wedge blade with a wedge.
Stick your feet well, keep a good balance and do not climb on the tree trunk.
Try not to work on a slope. However, if you have to work on a slope, always stand higher
than the tree trunk.
Before bending a branch or trunk in bending, observe the direction of bending and finish
the cut opposite the bending side to prevent the chain guide from getting stuck in the cut.
a. Felling of trees
Examine the work area and estimate where the tree will fall. Start the machine as
described above. Start by making a notch in the direction of fall chosen.
When the tree falls, shout or make a beep to alert people in the vicinity. When the shaft
falls, move away from the cutting area.

19
b. Trunk on the ground
Cut half of the trunk, turn it over and finish the cut on the other side.
c. Trunk in elevation
Begin by cutting a first part from below and then from above. Then, on the second
part, repeat this operation.
f. Pruning of a felled tree
Observe first the direction of flexion of the branch. Make a first notch on the side in
flexion and finish the cut on the opposite side.
g. Pruning a tree
Begin pruning by nicking the tree from below and then finish at the top.
