WARNING!
For safety reasons and for proper unit operation, it is extremely important that
the teeth are consistently well sharpened. Teeth need sharpening
When the sawdust looks like dust.
When greater force than usual is required to start cutting.
When the cutting path is not straight.
When the vibration increases.
When the fuel consumption of the unit increases.
Rules for setting teeth
WARNING!
Be sure to wear protective gloves for this job.
Before you start sharpening your teeth:
- Check that the chain is properly secured.
- Check that the engine is off.
- Only use a round file of suitable dimensions according to the size of the chain.
Place the file on the tooth to be sharpened and push it straight forward. Keep the file
in the indicated position maintaining an angle of 30º with respect to the back.
After sharpening each tooth, measure the depth with a caliper and file to the correct
level as shown in the illustration.
WARNING!
Be sure to round the leading edge to reduce the risk of kickback or chain binding. Check
that the length and edge angle of all teeth are the same as shown in the illustration.
GUIDE BAR
In order to avoid uneven bar wear, periodically invert the bar. The guide bar rail must
always be square. Check the wear of the rail with a ruler
1. FOR SAFE OPERATION
Please read this manual carefully to understand how this machine works.
1.1. You must not use this machine under the influence of drugs, alcohol, you must also not use it
under physical fatigue, sleep or under the influence of any medication, the cold or if you
do not feel able to use this machine as a result of other circumstances that result in you not being in

c) Position of the air lever to open the air inlet. Location: Air filter cover plate.
1.5. Keep the machine and the fuel can away from any heat source as well as any type of sparks
orflames.
1.6. Do not smoke while handling fuel or operating the chainsaw, there is danger of fire and / or
explosion, this could cause the operator serious injury or even death.
1.7. While cutting or starting the chainsaw, avoid people, children or animals in the work area. They
must be at least 10 meters apart.
1.8. Never use the chainsaw without a clear work area, good
foot support, and a safe escape to prevent trees or limbs from falling on you.
1.9. Hold the running machine firmly with both hands.
1.10. Keep all body parts away from the cutter chain while the engine is running.
1.11. Before starting the engine make sure that the cutting chain is not in contact with any object.
1.12. Transport the chainsaw only while the engine is off, with the guide bar pulled
back and keeping the exhaust pipe away from the body.
1.13. Before each use, carefully examine the chainsaw for worn, loose, or damaged parts.
If so, you must have it repaired and / or sharpened or replaced with another. Never use the chainsaw
if it is damaged, improperly adjusted, incomplete, or not securely mounted. Verify that
the chain stops moving when the throttle trigger is released.
1.14. All repairs and maintenance on this machine must be carried out by qualified personnel.
1.15. Be sure to turn off the engine before putting the chainsaw on the ground.
1.16. Be extremely careful when cutting shrubs or saplings. Brittle material from
these can get caught in the chain and fly towards the operator or cause a jerk causing you to lose
your balance.
1.17. When cutting a branch that is under tension, be prepared to step aside and avoid being struck
when it is released.
1.18. Do not mow in bad weather, in poor visibility, or in
very cold or very high temperatures. Make sure there are no dry branches that can fall.
1.19. Keep the grab handles dry, clean and free of fuel.
1.20. Avoid starting the engine indoors. The exhaust gases contain carbon monoxide
which is harmful to health as it could cause respiratory problems, with the danger that this entails.
1.21. Never try to fell a tree with this machine if you do not have the proper training for this kind of
task.
1.22. Protect yourself adequately against kickback that the chainsaw can cause while cutting.
Kickback is an upward movement that occurs when the end of the guide bar contacts an object.
This can cause you to lose
control of the chainsaw, which is extremely dangerous and can cause serious injury or death.
1.23. When transporting the chainsaw make sure it is stopped and the guide bar covered with its
safety cover.
1.24. Do not touch the motor, guide bar, chain or guide fixing nut with bare hands immediately after
turning off the motor. It could cause severe burns
(1) Engine
(2) Guide bar
(3) Chain
(4) Nut
Make sure there are no obstacles in the work area.
Do not allow the tip of the guide bar to contact a log, branch, or other obstacle that could cause
kickback. When cutting, run the engine at high revs.
Never work in a forced position or higher than your own shoulders.Follow the manufacturer’s
instructions for sharpening and maintaining the saw chain. Use manufacturer-specified guide bars
and chains.
KICKBACK PRECAUTIONS FOR CHAINSAW USER
WARNING!
Kickback can occur if the guide bar touches an object or when
the cut of the wood closes and locks the chain.
Tip contact in some cases can cause an extremely rapid reverse reaction, moving the guide bar up
and toward the operator. In any of these cases the operator can lose control of the chainsaw and be
seriously injured.
Never rely solely on chainsaw safety devices, they do not ensure total safety. When using the
chainsaw it is necessary to proceed according to carefully planned steps, to avoid accidents during
work.
By understanding the basic situations in which kickback occurs, you can reduce
or eliminate the element of surprise. The startle caused by sudden movement of
the chainsaw is a major factor in every accident.
Hold the chainsaw firmly with both hands: the right hand on the rear handle and the left hand on the
upper front handle when the engine is running. The thumbs and fingers of both hands should fit
firmly around the handles.
This allows to control the kickback of the chainsaw, the continued abuse of
the use of chainsaws, by causing other vibrations is likely to aggravate symptoms such as: numb-
ness of the hands, which can become chronic and make you lose the tactile sensation.
Raynaud’s phenomenon (soft fingers) caused by continuous vibrations. You may find it difficult to
pick up small materials such as screws or nails.
HOW TO PROTECT YOUR BODY
FROM VIBRATIONS
Always use the right tool for the job. Check tools before use to make sure they are in good mainte-
nance or have been properly repaired to avoid further
vibration. Make sure the chain is sharp.
Reduce the time you use the machine without stopping. Avoid putting too much pressure on the
chainsaw when cutting. Store the chainsaw so that its handles are not too cold the next time you
use it.
Stimulate good blood circulation: keeping your body warm and dry.
To gain blood flow it is advised not to smoke and to massage and exercise your fingers regularly.
When you decide to dispose of the machine, fuel and oil, be sure to do so in accordance with the
legislation in force in your area.

3. GUIDE BAR AND CHAIN INSTALLATION
WARNING!
The chainsaw chain teeth are very sharp. Wear suitable gloves as a protective
measure.
Make sure the chain brake lever is rearward, unlocking the brake. Loosen the
side nut and, depending on the model, a second anchor at the rear of the plate,
which fix the side plate and chain brake, and remove the plate.
Install the attached tooth into the tool bag on the right front of the engine, with the
tips facing up.
Shim the chain onto the sprocket next to the guide bar set screw. Put the guide bar
in position by going through it with the screw and around it with the cutter chain.
Tensioning the guide bar a little by hand, present the chain brake side cover and adjusting
the tensioner nut, check that the large hole in the bar matches the tensioner.
(1)Orifice
(2) Tensioner
(3) Chain brake side cover
Make sure to mount the chain in the correct direction.
(1) Tensioner bolt
(2) Loosen
(3) Tension
Put the chain brake cover in position and fit the nut tightening it by hand, never with
the tool. Stretching and lifting the tip of the guide bar up to tension the chain, tighten the
chain tensioner screw with the screwdriver so that the chain is finally taut.
Normal chain tension should allow you to lift the chain one finger above the guide
bar, pulling it upwards, if it is over-tensioned, the motor will not be able to turn it.
Tighten the nut with the wrench, making sure that it is fixed and manually check
that the chain slides without difficulty on the guide bar.
WARNING!
New chains tend to slacken, loosen the nut a little and tighten it, and retighten the nut
again. Never use the machine with the chain slack, it could come off and cause injury.
4. FUEL AND OILS
- GASOLINE
Gasoline is highly flammable, avoid smoking or producing
any type of flame or spark near the fuel.
Be sure to stop the engine and allow it to cool down before refueling the chainsaw.
Select an open field for refueling and move the chainsaw at least 3 meters (10
feet) away from the refueling point before starting the engine.
The engines are lubricated with a specific two-stroke engine oil for forestry and
garden machinery.
Do not use two-stroke oil for water-cooled
engines, and do not use the oil used by twostroke outboard engines or
scooters.
- PROPORTION OF THE MIXTURE RECOMMENDED BY THE MANUFACTURER (4%):
These engines are prepared to run on 95 unleaded gasoline mixed with 4%
forestry and garden two-stroke engine oil.
For example, if you want to mix a liter of gasoline, you should add 40ml of this type
of oil. Poor quality oils or oils not recommended by the manufacturer damage the
engine causing a major breakdown in the machine.
HOW TO MIX THE FUEL
1. Measure the amounts of gasoline and oil to be mixed.
2. Put some gasoline into a clean, approved
fuel tank.
3. Pour all of the oil into it and shake vigorously for approximately 30 seconds.
4. Pour in the rest of the gasoline and shake the mixture again for at least one minute.
Be careful, insufficient agitation increases the chances of engine seizure.
5. Place a clear indication or label on the outside of the tank to prevent it from being
confused with a deposit of other substances.
- UNIT SUPPLY
1. Unscrew and remove the fuel cap.
2. Put the fuel into the tank to 80% of the full capacity.
3. Cover the tank with the cap and wipe up any fuel spills on or around the machine.
WARNING!
1. Refuel on flat, clear ground.
2. Move the unit about 3 meters (10 feet) away from the supply point before starting the engine.
3. Stop the engine before refueling the unit. At this time, be sure to sufficiently stir the mixed gasoli-
ne in the tank.
- TO CONTRIBUTE TO THE LIFE OF THE ENGINE, AVOID:
1. Remember not to fill 95 gasoline without oil, this will destroy the engine.
2. Diesel: this can cause serious internal damage.
3. Oil for use in four-stroke engines: it would cause fouling of the spark plug and
the engine blockage among other failures.
4. Mixed fuels that have been left unused for a month or more often have deposits
and will cause carburetor failure.
5. In the case of storing the product for a long period of time, empty the fuel tank
and start the engine several times, allowing
it to turn itself off due to lack of fuel. This will ensure that the fuel circuit, including
the carburetor, is completely drained.
6. In the event of having to dispose of the gasoline mixing tank, do so only at an authorized
site.
- CHAIN OIL
It is essential that for greasing the chain of the chainsaw only use a product specifically
designed for it. In other words, special oil for lubricating chainsaw chains.
Any other oil that is introduced into the chain lubrication reservoir, in the medium-
long term, will damage the lubrication system causing a serious breakdown in the machine.
The machine could also experience excess temperature in the cutting parts which in
turn will transmit the excess temperatureto internal parts of the engine creating major breakdowns
and shortening the life of the machine.
WARNING!
It is very dangerous to work with the chainsaw when the chain or guide bar is
damaged or in poor condition. This can cause damage or even serious injury to the user.
5. ENGINE START
1. Fill fuel and chain oil tanks and retighten plugs.
(1) Chain oil
(2) Fuel
2. Place the switch in position I (on position)
3. Pull the choke button out.
NOTE: On models with a primer bubble, you have to press 5 times before starting
the starting process, to facilitate the delivery of fuel to the carburetor.
Pull the starter rope until you feel the machine make a sound identifiable as a
small start attempt. At this point, the choke must be returned to the initial position (all the way in). In
the event that you had not noticed that first gesture or attempted
start and had already pulled the rope 4 or 5 times, it is essential that you also insert
the choke inwards, otherwise the machine will drown and will not start.
At this point, we will simply pull the rope until the machine starts. When the gas nailer is activated,
the machine will start accelerated and simply by activating the accelerator, it will automatically
unlock.
- DROWNED ENGINE
In the event that we have drowned the machine or it does not start and we want to rule out that it is,
we will follow the following steps:
- We will raise the switch to position I and we will make sure that the throttle is fully
inwards and keeping the accelerator activated by means of the gas nailing button, we
will pull the rope until the machine starts.
If necessary, if we see that we have insisted a lot and the machine has not started, it
would not hurt to remove the spark plug and check that it is dry. Otherwise, we will
dry it, reassemble it and repeat the entire operation until the machine starts.
- Once the machine has started, we will keep the engine gently accelerated for a few minutes until it
is warm.
WARNING!
Avoid getting close to the chain as the chain begins to move once the engine starts.
- OIL SUPPLY CONTROL
WARNING!
Having made sure that the bar and chain have been properly assembled and that the
lubrication oil tank is full, we will proceed to verify that the oil actually greases the
chain, this is verified as follows: With the machine started, we will bring
the tip of the guide bar towards a material where oil splashes are easily visible, such as cardboard,
and we accelerate the machine to make the chain rotate at medium-high
revolutions until we can see that oil begins to splatter on the surface. At this time, and
not before, it will be when we can start cutting with the machine.
At the bottom of the machine we can locate a screw with a “min - max” mark, which is
used to adjust the lubrication oil flow.

can locate a screw with a “min - max” mark, which is used to adjust the lubrication oil flow.
This screw only has a quarter turn that must be respected, if we exceed this stop we will damage
the oil pump and it will have to be replaced.
It is essential that you have a constant control of the oil level in the oil tank, you must refill the tank
before it is empty. If it empties and you do not realize it, you will be cutting without greasing the
chain, endangering the integrity of the machine and your own.
- CARBURETOR ADJUSTMENT
The carburetor on this machine is adjusted at the factory. Although it has the screws to
adjust it, it is not recommended that you try it yourself as it is a complicated maneuver
that must be carried out by qualified personnel or you following the instructions of
said personnel. Otherwise you may totally misadjust the carburetor and have to go to
a technical service to have it fixed.
- CHAIN BRAKE
This machine is equipped with an automatic chain brake, this safety system will
protect you against a possible kickback by braking the grip of the cutting chain.
This brake can be operated manually by pushing the brake lever forward (B).
It is very important to verify that the chain brake is not activated when we go to work
with the machine, for this we will simply pull the brake lever towards the machine holding handle,
making sure that the brake is not forward.
In the event that we operate the machine with the chain brake on, we would severely
overheat the clutch area, chain brake cover and internal parts of the engine, causing a serious
internal and external failure.
- CHAIN BRAKE CHECK METHOD
1. Stop the engine
2. Find a sturdy piece of wood, such as a
cut log, lift the bar up and release the front
control.
Drop the guide bar with the weight of the machine so that it hits the wood.
With this action the brake should jump forward.
IMPORTANT:
In the event that, while working with the machine, the chain brake comes off, you
must immediately release the throttle trigger and turn off the engine.
- STOPPING THE ENGINE
1. Release the throttle trigger and let the
engine idle for a few minutes.
2. Place the switch in position “0” (stop).
6. USING THE CHAINSAW
Before starting the task, carefully read the section “for safe operation”. Practice cutting
easy logs is recommended to familiarize yourself with the machine.
- Always follow the safety regulations. The chainsaw should only be used to cut
wood. Cutting other materials is prohibited. Do not use the chainsaw as a lever to lift, move or split
objects. Do not work with the chainsaw if there is an object between it and the work surface. It is
forbidden to apply any utensil or accessory to the power take-off of the chainsaw that is not indica-
ted by the manufacturer.
WARNING!
It is not necessary to force the saw into the cut. Apply only light pressure against it
while working at machine speed. If the saw gets stuck while cutting, do not try to force
it out. Use a wedge or crowbar to open the cut so that it can be released.
- KICKBACK PROTECTION
This chainsaw is equipped with a chain brake, to protect us from possible kickback
during work. Verify that this works correctly as indicated in section 5.
Also, it is worth testing the chain brake with the machine running, accelerating
two seconds and activating it.

In the event that it does not work properly,
do not use the machine under any circumstances and go to a specialized workshop.
It is extremely important to check the operation of the brake, you should also check that the chain
teeth are well sharpened for your safety. In the event that these warnings are not heeded, or the
machine is not properly maintained, it will endanger its physical integrity.
- CUTTING TREES
1. Decide in which direction you want the tree to fall, taking into account the wind
direction, the inclination of the tree, the location of heavy branches, the ease of
tasks after the tree has fallen, and any other related factors.
2. Clean the work area and verify that you have good foot support and a good escape route.
3. Make a notch up to one-third the diameter of the log on the felling side.
4. Make a felling cut on the opposite side of the notch, at a level slightly higher thanthe bottom of
the notch.
WARNING!
Before felling a tree be sure to warn other workers on the perimeter.
- CUTTING THE BRANCHES
WARNING!
Make sure you have a firm footing. Never work while standing on top of the trunk.
Take special care when doing these jobs, as the log can roll to one side. When working on a slope,
stay at the top of the hill. Follow the instructions given in the “For Safer
Operation” section to avoid kickback from the chainsaw. Before starting work, check the direction
of the bending force inside the log to be cut.
Always end the cut on the opposite side to the direction of the bending force to avoid catching the
bar in the cut. Make a cut halfway through the trunk. Back to the log
and finish the cut from another side. In area “A” start cutting from the bottom
to one-third the diameter of the log and finish the cut from the top in area “B”,
start cutting from the top to one-third the diameter of the log and finish the cut from the bottom.
Check which way the branch to be cut is bent. Start by making a cut from the side to which it is bent
and finish the cut from the other side.
In area “A” start cutting from the bottom to one-third the diameter of the log and
finish the cut from the top in area “B”, start cutting from the top to one-third the diameter of the log
and finish the cut from the bottom.
Check which way the branch to be cut is bent. Start by making a cut from the sideto which it is bent
and finish the cut from the other side.
WARNING!
Work carefully as the cut branch can jump backwards. Start cutting from the bottom and finish
cutting from the top.
WARNING!
- Check that you have a firm footing before starting work. Do not use stairs.
- Avoid reaching out to cut the branches of a tree.
- Never cut higher than your own shoulders.
- Always hold the chainsaw firmly with both hands.
7. MAINTENANCE
WARNING!
Before attempting to clean, inspect, or repair your chainsaw make sure the engine
is off and cool. Disconnect the spark plug wire to prevent the engine from accidentally
starting.
- MAINTENANCE AFTER EACH USE
1. Air filter
Dust on the surface of the filter can be removed by tapping a corner of the filter
against a rigid surface. To clean the dirt from the screens, divide the filter into two
halves and brush it with gasoline. If you use compressed air, blow from the inside.
OWNER’S MANUAL | ENGLISH
To assemble the two filter halves, press the edge until it clicks.
IMPORTANT:
When installing the main filter, check that the grooves on the edge of the
filter are fully wedged and that it is perfectly adjusted in the carburetor inlet.
2. Oil filler neck
Remove the guide bar and check that the oil filler neck is not clogged or dirty.
3. Guide bar
Remove guide bar and remove all remaining sawdust from guide bar slot and oil
filler neck. Grease the sprocket through the lubrication hole located at the end of the guide bar.
4. Others
Check for fuel leaks or loose connections. Examine the main parts for possible signs
of damage especially the handlebar and its anchoring parts. Also check the mounting of the guide
bar.
If defects are found, make sure necessary repairs are made before using the unit
again.
Periodic service points
1. Cylinder fins
Dust between the cylinder fins causes overheating. Periodically check and clean
the cylinder fins after removing the air filter and engine cover. When installing
the cylinder cover make sure that the motor connectors and grommets are properly seated in place
.
NOTE: Be sure to cover the air intake before starting this job.
2. Fuel filter
A) Using a wire hook remove the filter from the filler neck
B) Disassemble the filter and clean all parts with gasoline.
Replace with a new filter if necessary.
NOTE: After drying the filter, use a pliers to hold the end of the suction tube. When mounting the
fuel filter, be careful to prevent fibers or dust from entering the suction tube.
3. Oil tank
Using a wire hook, pull the oil filter out through the oil filler hole and clean it with gasoline. When you
put the filter back into the tank make sure it reaches the right front corner. Also, clean the dirt from
the tank.
4. Spark plug
Clean the spark plug electrodes using a wire brush. Verify that the gap between
the two electrodes is 0.65mm and make any necessary adjustments.
5. Sprocket
Examine the sprocket for signs of cracks or excessive wear that may affect chain
movement. If obvious wear is observed, replace the worn sprocket. Never chock a
worn chain on a worn sprocket or a worn chain on a new sprocket.
