2.3.1. Throttle lock The throttle lock is designed to prevent the machine
from starting accidentally. When you press the lock (A),
it releases and releases the throttle trigger (B).
When you release the control, both lock and throttle
triggers will return to their original position. This
movement is controlled by two independent springs.
This safety feature returns the engine speed to its idle
level whenever the machine control is released.
Make sure the throttle control is set to
idle level when the accelerator is released.
Press and verify that the throttle lock trigger returns to its original position each
time you release it.
Check that the lock and throttle triggers move freely and that the return springs on
both operate properly.
See the machine's starting instructions. Turn on the machine and
After a few moments of tempering, press the
accelerator fully. Release the accelerator and
check that the cutting instrument stops
completely and remains static. If the cutting
instrument continues to rotate at this point,
the idle level must be checked and the
carburetor adjusted accordingly.
2.3.2. Off switch
Press the switch to the “O” off position to turn off the engine. Turn on the
machine and make sure the motor turns off when you turn on the switch.
2.3.3. Cutting guard
This protector serves the purpose of preventing certain
debris from being thrown backwards towards the operator's
position. It also protects the operator from possible contact
with the cutting instrument. Check that this protector is not
damaged or broken. Replace it if it has received a strong
impact or is cracked or broken. Always use the protector
recommended for the machine you are using.
ATTENTION: Never use a cutting element without the cutting
guard properly installed. See the technical data chapter. Using an
inappropriate, modified or damaged protector can cause very
serious personal injury.
2.3.4. Anti-vibration system
Your machine is equipped with a special damping system
that reduces and minimizes the effects of engine and
transmission vibration.
If you use an inappropriate or poorly balanced cutting
element, the effects of vibration will increase considerably.
The anti-vibration system reduces the vibrations transmitted
by the motor and cutting unit to the operator's control handlebar. Regularly check
the anti-vibration system and check for broken or worn shock absorbers.
Check that the anti-vibration system components are properly secured to the
machine.
2.3.5. Quick harness release
The machine is equipped with a quick harness release system (mooring point on
the anti-vibration system) for cases in which the machine may catch fire or another
situation requires releasing the operator from the machine. Regularly check that
the system is working properly before each use.
2.3.6. Exhaust
The exhaust is designed to reduce noise as much as possible and
expel combustion gases away from the user.
Never use a machine with a defective exhaust.
Regularly check that the exhaust is securely attached to the
machine and has no damage.
ATTENTION: The interior of the exhaust contains elements that
may be carcinogenic. Avoid contact with these elements in a
damaged exhaust. Replace the exhaust if it shows any damage.
Always keep in mind that the gases expelled are at a high temperature and
may contain incandescent sparks that can cause fires. Never turn on the
machine in closed areas and areas close to flammable materials such as fuel,
etc.
2.3.7. Tightening nut
A tightening nut on the head is used to adjust certain cutting
elements. This is tightened counterclockwise and against the
direction of rotation of the head. To loosen it, you must do so in the
direction of rotation of the cutting element (ATTENTION: the nut has
a left-hand thread). Tighten the nut with the appropriate wrench
provided with the machine.
The inner nylon of the tightening nut must offer adequate resistance
so that the nut does not loosen on its own, but should allow for
heading and threading by hand. The resistance level should
be at least 1.5Nm. The tightening nut must be replaced after it has been put on about 20
times.
2.4. Cutting equipment
This section advises the user on how to choose the appropriate cutting equipment in order to:
- Reduce the risk of rebound
- Get maximum cutting performance
- Extend the life cycle of your cutting equipment
IMPORTANT: Only use cutting equipment with the protectors we recommend
on the machine. Check the instructions for placing the cutting equipment to
do it correctly.
Keep the blade cutting teeth properly sharp. Follow
our recommendations. Use cutting blade protection for transport and storage.
ATTENTION: Always turn off the machine before making any adjustments or
changes to the cutting equipment. It can rotate even when the throttle has been
fully released. Make sure the cutting element has stopped completely and
disconnect the spark plug wire before working on it. Using an inappropriate cutting
element or a poorly sharpened blade increases the risk of kickback movements
in the machine.
2.4.1. Cutting element attachment
The steel discs/blades are indicated for
use on grass or bushes.
A nylon head is used for trimming and mulching
grass or grass.
Only use cutting elements with
appropriate protections for the machine.
Never use other types of cutting elements
such as pivoting chain heads or blades.
floating, as they can cause damage to the machine and serious injuries to the user.
Keep the cutting teeth of the blades properly sharpened. Follow the
recommendations and use appropriate files. A poorly sharpened blade/disc increases
the risk of accidents.
Check the cutting element regularly for damage or breakage. A damaged
cutting element must be replaced.
2.4.2. Sharpening cutting blades
Sharpen the cutting discs/blades with a flat file. Sharpen all
edges equally and at the same level to keep it balanced.
ATTENTION: Always remove any bent, cracked,
broken or damaged disc/blade. Never attempt to
straighten a bent disc for reuse. Only use original
discs/blades according to the type required.
2.4.3. Nylon head
IMPORTANT: Always make sure that the cutting line is correct in size,
balanced and properly tensioned with respect to the main reel,
otherwise the machine will generate great vibration.
Use only recommended cutting line heads
with the appropriate measurements.
Each thread head has been tested by the
manufacturer to be used on different machines
according to its power and characteristics. Check the head specifications, especially
those of the semi-automatic type, and only use heads that fit the characteristics of
the machine.
Smaller machines generally use smaller heads and vice versa. This is because the
machine has to overcome with its power the tensioning resistance of the thread and
the resistance of the material to be cut.
The length of the cutting line is very important. A longer thread requires greater
machine power than a shorter thread of the same diameter.
Make sure the cutting guard for the cutting head is correct and undamaged. The
guard itself is used to adjust and cut the cutting line to the correct size.
To increase the life of the nylon thread you can soak it in water for a couple of days.
This will make the thread more resistant and will last longer at work.

3.1.6. Harness adjustment
ATTENTION: When using the brush cutter you must always attach
it securely to the harness. Otherwise you will be unable to control
the machine safely and may cause serious injury to yourself or
others. Never use a harness with a defective automatic release.
At the front there is an accessible quick release. Use it in cases where the
machine starts to burn or in any other situation where you need to free
yourself quickly from the machine and your harness.
A well-fitted and balanced harness makes the job easier and more
comfortable. Adjust it to the best working position based on your
size and type of work. Adjust the side straps so that the weight is
evenly distributed across your back and both shoulders.
Adjust the shoulder strap until the cutting element is parallel to
the ground in terms of height.
Let the cutting element rest gently on the ground. Adjust the
harness attachment on the trimmer (suspension point) to balance
the weight of the machine.
3.2. Fuel management
3.2.1. Fuel safety
Never start the machine:
- If fuel has been spilled on it. Wipe up spills and allow remaining fuel to evaporate.
- If you have been wet with fuel or your clothes contain flammable products. Change
clothing and wash away any remaining fuel.
- If the machine has fuel leaks. Regularly check the fuel cap, tubes and other components
of the fuel system for damage or leaks. Repair immediately before any use.
3.2.2. Transportation and storage
a. Transport and store the machine and its fuel so that there is no risk of leaks or
fumes coming into contact with sparks or fire, for example, away from
electrical machinery, electric motors, switches or other power systems.
b. When transporting or storing fuel, always do so in tanks approved for
this purpose.
c. When storing the machine for long periods of time the fuel tank must be emptied.
Consult your fuel dealer to learn how to properly handle excess fuel.
d. Carry out a deep cleaning of the machine and a technical inspection of
the brushcutter before a long period of storage.
e. The cutting guard must always be installed when the machine is
transported.
F. Properly secure the machine in transport.
g. In order to avoid spontaneous starts, the spark plug cap must be removed
during long periods of storage if the machine is not under surveillance or
preventive
service has not been performed.
ATTENTION: Take special care when handling fuel. Always keep in mind the
possibility of fire, explosion or inhalation of gases.
3.2.3. Fuel
The brush cutter is equipped with a 2-stroke combustion engine and must be fed
with a mixture of gasoline fuel and lubrication oil for engines of this type.
It is very important to maintain the correct proportion in the fuel mixture and
accurately measure the quantities in the mixture. When mixing small amounts of
fuel, a small variation in the amounts of oil and gasoline can seriously affect the
mixture and its quality.
ATTENTION: The fuel and the gases it gives off are highly flammable and can cause
serious injuries by inhalation or contact with the skin. Be careful to avoid these
situations when handling fuel and do so in ventilated areas.
3.2.4. Gasoline
Always use good quality gasoline with at least 90 octane (RON). If the
machine has a catalytic converter, always use a rich mixture of
unleaded gasoline and 2T oil. Leaded gasoline will destroy the catalyst.
Use low-emission gasoline if available from your dealer. The lowest
recommended octane rating is 90 (RON). If you use gasoline
Octanes lower than 90 can cause engine collapse and seizure. It is caused by the
increase in temperature in the engine, which will cause serious damage.
If you work at high engine speeds and for longer periods of time, it is recommended to use a
higher octane rating.
3.2.5. 2T mix oil
Use properly blended and formulated oil for two-stroke air-cooled engines.
Never use blend oil for water-cooled (TCW) engines. Never use 4-stroke
engine oil.
A mixture that is too lean in oil or in excess in proportion will affect engine
performance and reduce the life of the catalyst.
Mixing ratio: 1:40 (2.5%) for JASO FC or ISO EGD oils formulated for use in air-cooled
two-stroke engines.
2T oil in milliliters
Liters of gasoline 2.5% (1:40)
1 25
5 125
10 250
20 500
3.2.6. Preparation of the mixture
- Always mix fuel in an appropriate tank.
- Start filling with half of the gasoline you are going to use.
Then add the corresponding amount of oil to the total
gasoline. Mix this portion first in the tank. Finally add the rest
of gasoline and mix the total again.
- Stir the fuel mixture vigorously before fill the machine tank.
- Do not make fuel mixtures for quantities greater than one month of use.
- If the machine is not going to be used for a while, the fuel tank must be emptied
and cleaned.
3.2.7. Supply fuel
Take the following precautions in order to reduce the risk of fire:
a. Do not smoke or place high temperature objects nearby.
b. Always turn off the machine before refilling the fuel tank.
c. Stop the engine and let it cool for a few minutes after a working time to
refill.
d. When refueling the machine, loosen the tank cap slowly to gently release
any excess internal pressure.
e. Carefully and securely tighten the cap once refilled.
F. Remove the machine from the refilling area and start the engine in a remote area.
g. Use a fuel tank with an automatic anti-spill valve.
h. Clean the area around the fuel cap. Dirt inside the fuel tank can affect
the performance of the machine.
i. Make sure the fuel is well mixed by always stirring the mixture before any refill.
3.3. Use of the machine
3.3.1. Checking and starting
- Never use the machine without the cutting guard or with a
damaged cutting guard.
- All covers must be correctly placed and in perfect condition
before turning on the machine.
- Check the cutting disc/blade for breaks or defects. Have the
cutting element properly sharpened and balanced. Discard any disc/
blade that is damaged, bent or poorly sharpened and replace it with
a new one.
- Check the cutting element tightening washer to ensure that it is
not broken or damaged. Replace if damaged.
- Check the cutting element tightening nut and that it is correctly
tightened. Discard the tightening nut if it is damaged and replace it
with a new one. The tightening force of the nut is about 35-50Nm.
- Check that the cutting guard is not damaged or broken. Replace
the cutting guard if it has been exposed to strong impacts or is
broken.
- Check that the nylon cutter head and cutting guard are not broken
or damaged. Replace them if they are broken or damaged. Check
the nylon line load for the job you are going to do and refill
beforehand if necessary.
3.3.2. On and off
Before starting, the clutch cover and drive rod cover must be correctly
positioned. Otherwise the clutch could become loose and cause serious
damage.
Always remove the machine from the area where you have refueled before
starting it.
Place the machine on a flat surface.
Make sure that the cutting element does not hit any object, person or animal.
Do not allow unauthorized persons in the work area, as there is a very significant
risk of serious injury. The safety distance is 15 meters.
3.3.2.1. Cold start:
This type of start is required when the machine has more than 5
minutes off since the last job or after long periods of storage.
a) Power on: Press the power switch to the “I” position.
b) Choke: Place the choke lever in the closed position to enrich the
fuel supply to the engine.
c) Fuel primer: Press the primer repeatedly until the fuel circulates
in it. The primer does not need to be completely filled.
ATTENTION: The choke lever will return to its initial position after
depressing the accelerator. If you move the choke lever to the initial
position, the cutting element can start rotating immediately after
ignition.
d) Secure the machine motor on the ground using your left leg
(attention: do not use your foot!). Grasp the starter handle, gently
pull the rope with your right hand until you feel some resistance
(the moment when the starter pawls grip), and then pull quickly
and forcefully on the rope. Never wrap the starter rope around
your hand, use the puller only. Repeat the operation until explosion
occurs and ignition.
e) Press the throttle gently and let the choke lever return to its
initial position.
f) Repeat the operation of pulling the starter until the machine
starts.
When the machine starts, accelerate gently for a few minutes so that the engine
gains temperature before starting to work.
Do not pull the starter rope to its full extent and do not release the starter
handle when the rope has been pulled. This may damage the machine.
Do not place any part of your body in the marked area. You may
suffer burns or electric shock if the spark plug cover has been
damaged. Always wear gloves. Do not use a machine with a
damaged spark plug cover.
IMPORTANT: If the starter handle is operated repeatedly with the choke
in the closed position, the engine may stall and become more difficult to
start. If this occurs, repeat the hot start to remove excess fuel in the
machine cylinder.
3.3.2.2. Hot start :
To start the machine after a short time since it has been turned off (no more
than 5 min) follow the steps described above, ensuring that the choke has
been pressed about 2-3 times.
3.3.2.3. Shutdown:
Turn off the machine by moving the control switch to the “O” position.
3.4. General work tips
IMPORTANT: This section describes basic work and safety techniques on brush
cutters. If you encounter a situation where you are unsure how to deal with it
while working, consult an expert. Contact your point of sale or specialized
workshop.
Avoid using the machine in situations that exceed your control and safety
capabilities. You must understand the difference between forestry (bush) clearing,
grass cutting, and grass cutting before you start using the machine.
3.4.1. Basic safety rules:
- Look and observe around the work area:
To ensure that other people, animals or agents cannot
affect the control of the machine.
To ensure that other people or animals cannot access the
cutting area or come into contact with the cutting element or
debris released from the cutting head.
Do not use the machine if you are not able to request help
in the event of an accident.
- Inspect the work area. Remove loose objects such as stones, glass, wires, etc. which
can be thrown when they come into contact with the cutting element or be wound on
it.
- Do not use the machine in bad weather, such as thick fog, heavy rain, wind, severe
cold, etc. Working in such situations will exhaust you faster and add risks to your
safety such as frozen ground, reduced visibility, unpredictability in cutting, etc.
- Make sure you can move safely and your working position is stable. Check the work
area for possible obstacles (roots, stones, branches, grooves, etc.) when making quick
movements. - Take special care when working on slopes.
- Always hold the machine with both hands. Place the machine on
the right side of your body.
- Keep the cutting element lower than your waist.
- Turn off the machine before moving to another work area.
Always equip the cut guard when transporting your machine.
- Never let go of the machine or abandon it with the engine
running, unless it is a clear area.
ATTENTION: The operator or any other person should never move the cut material
away while the engine is running or the cutting element is operating, as serious
injury could result.
The transmission elbow can reach high temperatures during use.
the machine and must rest to cool. You could be seriously burned if you touch it. Monitor
the waste emitted by the machine. Always wear appropriate eye protection. Rocks, trash, or
other debris thrown by the machine can cause blindness or serious eye injury.
Never lean on the cutting guard.
Keep people outside of work at a distance while you work. Children, animals,
observers or collaborators must be at least 15 meters away. Turn off the machine if
anyone approaches and enters your work area. Never turn the machine backwards
without first ensuring that no one is behind you within the safety area.
3.4.2. Basic work techniques
Always reduce the engine to idle after each operation. Long periods at full throttle
without load can damage the engine.
ATTENTION: Branches or grass can get caught between the cutting guard and the
cutting element. Always stop the machine before cleaning them.
The brush cutter may bounce suddenly when it comes into contact with a
fixed element and when you equip the cutting disc/blade. This rebound can have enough force
to move the machine and its operator uncontrollably in any direction. Kickback usually occurs
when the elements to be cut are difficult to see or there is a lot of weeds.
Avoid cutting in the disc/blade area marked between the 12 and 3 o'clock positions (similar to
a clock). Due to the speed of rotation of the cutting element, kickback may occur if you
attempt to cut thick branches in this area of the blade.
3.4.3. Grass cutting with disc/blade
Grass discs/blades should not be used on wooden
branches.
Can be used for tall or short grass.
Cutting grass must be carried out with a lateral and
oscillating movement, where the movement from right to
left is what must be used to make the cut, and the
movement from left to right allows us to return to the
starting point of the cut.
The cut must be made on the left side of the disc/blade (between the 8 and 12
o'clock positions).
If the blade is turned slightly to the left while cutting, the grass can be placed in a
line, which will make it easier to collect rather than raking it. Try to work in a
rhythmic way. Place your feet safely and firmly. Move forward after the return
movement in the cut and regain a safe position before advancing with the cutting
movement.
Allow the support cup on the cutter head to rub against the ground. It is designed to
protect the cutting disc from hitting the ground while doing this type of work.
Reduce the risk of certain materials becoming entangled in the cutting element by
following these instructions:
- Always work at full power, with the accelerator at full throttle when cutting.
- Avoid rubbing the cut material in the return movement.
3.4.4. Grass cutting with nylon head
3.4.4.1. Grass Trimming: Place the cutting head right on the ground and with a
slight
angle. The work must be done with the final tip of the nylon. Let
the nylon work at its own pace. Do not put more line than
necessary into the cutting area.
The nylon thread can easily clean grass and shoots against
walls, walls, fences, trees and edges, although
It can also damage the skin of trees and fence posts. Reduce the risk of damaging trees
and plants by reducing the length of the line to 10-12 cm and maintaining a low working
speed.
3.4.4.2. Grass clearing: This technique removes all unwanted vegetation in one
certain area. Place the cutting head above the ground and
move it in various directions. Let the end of the nylon hit the
ground around trees, posts, walls, and so on. ATTENTION:
this technique increases the consumption of nylon.
The nylon will wear out sooner and faster, so it will need to
be refilled more often if working against stones, bricks,
cement, metal fences, etc.; and it will have less consumption if it hits trees or wooden
posts.
When trimming or cleaning with the nylon head, you can use the machine at a lower
speed than full power, as this will make the nylon last longer and reduce wear on the
cutting head.
3.4.4.3. Cutting: The nylon cutter head is ideal for cutting grass or grass where not
It can be accessed with a lawnmower. Keep the cutting
line parallel to the ground while cutting. Avoid putting the
cutting head completely close to the ground to avoid
damaging the grass and the cutting head.
Do not let the cutting head hit the ground while working. This will prolong the
useful life of the head and prevent wear.
3.4.4.4. Sweeping: The fan effect of the cutting line can be
used for quick cleaning and sweeping. Place the line parallel to
and above the area to be swept and move the machine in the
direction you need.
Use the machine at full power for best results.
3.5. Maintenance
3.5.1. Carburetor
Idle speed adjustment (T)
Check that the air filter is clean. When the idle speed is
correctly adjusted the cutting head should not rotate.
If idle adjustment is required, close (turn clockwise) the
carburetor T screw with the engine running. Then open
(turn counterclockwise) the same screw until the
cutting element stops completely. This type of
adjustment will be correct when the engine operates at
a smooth speed in all positions and
There is a clear speed range until the cutting element begins to rotate.
ATTENTION: If the carburetor adjustment cannot be carried out, consult the
appropriate technical service of your dealer. Do not use the machine until it is
properly adjusted and repaired.
If it is necessary to adjust the L and/or H screw, consult your service center for advice.
3.5.2. Air filter
The air filter must be cleaned to remove dust and dirt in order to avoid:
- incorrect operation of the carburetor.
- starting problems.
- loss of power in the engine.
- unnecessary wear on internal engine parts.
- excessive fuel consumption.
Clean the filter every 25 hours, or more frequently if conditions are
excessively dusty.
Clean the air filter:
Remove the air filter cover and remove the filter.
Wash it in warm soapy water. Let it dry properly
before replacing it.
An air filter with many hours of use cannot be
completely cleaned. It will have to be replaced with
a new one from time to time. If the filter is
damaged or broken it must be replaced.
3.5.3. Fuel filter
If the machine experiences poor fuel delivery to the engine,
check the fuel filter in the tank to see if it is clogged.
The fuel filter can be replaced from time to time to avoid
blockages in the fuel supply.
3.5.4. Transmission elbow
The transmission elbow is filled with just the right amount of
grease from the factory. However, you should check before each
use that the gear elbow is three-quarters full of grease.
The elbow lubrication grease should not be replaced
unless that any major repairs have been made.
3.5.6. Spark plug
Spark plug performance is affected by the following factors:
- Incorrect carburetor adjustment.
- An incorrect fuel mixture (too much oil or wrong type of
oil)
- A dirty air filter.
These factors cause deposits to build up on the spark plug electrodes, resulting in
