GENERAL SAFETY INSTRUCTIONS FOR POW-
ER TOOLS
WARNING! All safety instructions, user manuals,
images and regulations supplied with these tools
must be read. Failure to follow all of the following
instructions may result in electric shock, fire, and/
or serious personal injury.
All instructions and the user manual must be
kept for future reference.
The term "power tool" in all the following
warnings refers to a mains-powered tool (with
a power cord) or a battery-powered tool (with-
out any power cord). This manual applies only
to power tools that are powered by a battery
without a power cord.
Safety in the working environment
The workplace must be kept clean and well lit.
Clutter and dark areas are often the cause of
accidents.
Power tools must not be used in potentially ex-
plosive atmospheres where flammable liquids,
gases or dust are present. Power tools create
sparks that can ignite dust or fumes.
Children and other persons must be kept away
when using power tools. If the operator is dis-
tracted, they may lose control of the operation.
Electrical safety
The operator must not touch grounded ob-
jects, such as pipes, central heating units,
cookers and refrigerators. The risk of electric
shock is greater if your body is connected to
the ground.
Power tools must not be exposed to rain, mois-
ture or wetness. If water enters the power tool,
the risk of electric shock increases.
The tool can generate a weak electromagnetic
field that is not dangerous to humans. Howev-
er, persons with pacemakers or similar devices
should contact the manufacturer of the device
or consult their doctor for advice.
Safety of persons
When using a power tool, the operator must be
careful, pay attention to what they are doing,
concentrate and think clearly. Power tools must
not be used if the operator is tired or under
the influence of drugs, alcohol or medication.
A moment’s inattention while using a power
tool can result in serious personal injury.
Use personal protective equipment. Always
use eye protection. Protective equipment such
as a respirator, non-slip safety shoes, hard hat
and hearing protection, used in accordance
with the working conditions, reduces the risk of
personal injury.
Unintentional starting of the machine must be
avoided. Make sure that the switch is in the off
position before connecting the battery, lifting
or carrying the tool. Carrying the tool with your
finger on the switch or with the tool switched
on can cause accidents.
All adjusting tools or wrenches must be re-
moved before switching on the tool. An ad-
justing tool or wrench that remains attached to
the rotating part of the power tool may result in
personal injury.
The operator must only work in places that they
can safely reach. The operator must always
SAFETY INSTRUCTIONS
9ENGLISH
maintain a stable posture and balance. This will
allow better control of the power tool in unfore-
seen situations.
Dress appropriately. Do not wear loose cloth-
ing or jewellery. The operator must make sure
that their hair and clothing are a sufficient dis-
tance away from moving parts. Loose clothing,
jewellery and long hair can be caught in mov-
ing parts.
Where equipment is provided for connecting
dust extraction and collection facilities, care
must be taken to ensure that it is connected
and used correctly. The use of such equipment
can reduce hazards caused by dust.
The operator must not allow themselves to
become lax and ignore the principles of work
safety due to the routine that results from the
frequent use of the tool. Careless actions can
cause serious injuries in a split second.
Use and maintenance of power tools
Power tools must not be overloaded. It is es-
sential to use the correct power tool for the
work being carried out. The correct power tool
will do the work it was designed to do better
and safer.
Power tools that cannot be switched on and off
with the switch must not be used. Any power
tool that cannot be operated with the switch is
dangerous and must be repaired.
The battery must be removed from the power
tool before making any adjustments, changing
accessories, or storing power tools. These pre-
cautions reduce the risk of accidentally starting
the power tool.
Unused power tools must be stored out of
the reach of children. Persons unfamiliar with
the power tool or these instructions must not
be allowed to use the power tool. Power tools
are dangerous in the hands of inexperienced
users.
Power tools and accessories must be main-
tained. The adjustment and mobility of moving
parts must be checked and attention focused
on cracks, broken parts and any other circum-
stances that may compromise the function of
the power tool. If the tool is damaged, it must
be repaired before use. Many accidents are
caused by poorly maintained power tools.
Cutting tools must be kept sharp and clean.
Properly maintained and sharpened cutting
tools are less likely to catch on material or jam
and are easier to control.
Power tools, accessories and tool bits etc. must
be used in accordance with these instructions
and in the manner intended for the particular
power tool, taking into account the working
conditions and the work to be carried out. Us-
ing power tools for activities other than those
for which they are designed can lead to dan-
gerous situations.
Handles and grip surfaces must be kept dry,
clean and free of grease. Slippery handles and
gripping surfaces mean the tool cannot be
held and controlled in unexpected situations.
Do not use cloth work gloves when using pow-
er tools as these can become entangled. Cloth
work gloves becoming tangled in moving parts
can cause personal injury.
Use and maintenance of cordless tools
The tool must only be charged with the charger
specified by the manufacturer. A charger that
may be suitable for one type of battery pack
may cause a fire risk when used with another
battery pack.
The tool must only be used with a battery that
is specifically designed for the tool. The use of
any other batteries may cause a risk of injury
or fire.
When the battery is not in use, it must be pro-
tected from contact with other metal objects,
such as paper clips, coins, keys, nails, screws,
or other small metal objects that can cause one
battery contact to come in contact with anoth-
er. Short-circuiting the battery terminals may
cause burns or fire.
If used incorrectly, liquids may leak from the
battery; contact with them should be avoided.
In the case of accidental contact with these flu-
ids, the affected area must be rinsed with water.
In addition, seek medical attention if fluid gets
into the eye. Liquids escaping from the battery
can cause inflammation or burns.
A battery or tool that is damaged or modified
must not be used. A damaged or modified
battery can exhibit unpredictable behaviour,
which can result in fire, explosion, or the risk of
SAFETY INSTRUCTIONS
10 ENGLISH
injury.
The battery or tool must not be exposed to fire
or excessive heat. Exposure to fire or tempera-
tures above 130°C may cause an explosion.
All charging instructions must be followed,
and the battery or tool must not be charged
outside the temperature range specified in the
operating instructions. Improper charging or
charging at temperatures outside this range
may damage the battery and increase the risk
of fire.
Servicing
Power tool repairs must be carried out by qual-
ified personnel using identical spare parts. This
will ensure the same level of safety of the pow-
er tool as before the repair.
Damaged batteries must never be repaired.
Batteries should only be repaired by the manu-
facturer or an authorized service centre.
Follow the instructions for deleting and replac-
ing accessories in this manual.
SAFETY INSTRUCTIONS FOR HAND SAWS
WARNING: This hand saw is designed exclusive-
ly for tree branching.
The saw must only be used by trained person-
nel using a carefully designed safe working
system.
Keep all body parts away from the chain, es-
pecially when the saw is in operation. Before
starting the saw, make sure that the chain does
not touch anyone or anything. A moment’s inat-
tention while handling a running saw can cause
clothing or body parts to come in contact with
the chain, which can cause serious injury.
Keep handles dry, clean and free of oil or
grease. Greasy or oiled handles can cause the
saw to slip so you lose control of it.
Always hold the saw with both hands. Always
hold the saw by the main handle with your right
hand and the front handle with your left. Re-
versed holding increases the risk of injury and
the saw should never be held in this way.
Only hold power tools in insulated places if
hidden wiring is cut. If the chain comes into
contact with live lines, the metal parts of the
saw that are also live may explode and the op-
erator may suffer an electric shock.
Wear eye and ear protection. We recommend
using head, hand, leg and foot protection.
Proper protective clothing reduces the risk of
injury from flying debris or contact with the
chain.
Use clamps or similar tools to secure the work-
piece on a stable surface. Holding the work-
piece in your hand or against your body does
not provide sufficient stability and can lead to
loss of control.
Make sure you wear suitable work shoes for op-
erating power tools, especially when standing
on stairs or ladders. Slippery or unstable sur-
faces can cause you to lose balance and control
of the saw.
Only move the power tool closer to the work-
piece when it is switched on. Otherwise, there
is a risk of kickback if the power tool gets stuck
in the workpiece.
Make sure that the guard is placed securely
when cutting. A jammed chain may break or
cause kickback.
When you have finished cutting, switch off the
power tool, wait until it has come to a complete
stop and then remove it from the cut. In this
way it prevents kickback and you can store your
power tool safely.
Only use an undamaged chain that is in perfect
condition. A bent or blunt chain can break, ad-
versely affect cutting or lead to kickback.
After switching off, do not brake the saw chain
until it stops by pushing on the side. The saw
chain can be damaged, broken or kickback.
Use suitable detectors to determine hidden ca-
bling or contact your local electricity supplier.
Contact with cabling may result in fire or elec-
tric shock. Damage to a gas pipe can lead to an
explosion. Damage to water pipes can cause
damage to the property.
The chain may break under excessive loading.
In this case, replace the chain with an original
part.
Causes and protection of the operator against
kickback:
Kickback can occur when the tip of the guide
bar touches a foreign object or when the wood
SAFETY INSTRUCTIONS
11ENGLISH
behind the saw contracts and grips the chain in
the cut. Tip contact can cause sudden kickback
in some situations and can throw the guide bar
up and back at the operator. Clamping the chain
along the top of the guide bar can quickly push
it back towards the operator. Each of these re-
actions can cause you to lose control of the saw,
which can result in serious personal injury. Do not
rely solely on the saw's built-in safety features. As
a chainsaw user, you should take a few steps to
prevent accidents or injuries while cutting.
Kickback is the result of improper use of the tool
and/or improper operating procedures or condi-
tions and can be prevented by taking the follow-
ing appropriate measures:
Hold the handles firmly so that your thumbs
and fingers encircle the chainsaw handles.
Keep both hands on the saw. Stand up and
stretch your arms to withstand the force of re-
coil. The recoil force can be controlled by tak-
ing the appropriate action. Do not activate the
chainsaw.
Do not overestimate your strength and do not
cut at a height above shoulder level. This will
help prevent unwanted contact with the guide
bar tip and allow better control of the saw in
unexpected situations.
Only use the original replacement guide bar
and chain recommended by the manufacturer.
Non-original or non-recommended replace-
ment guides and chains can cause damage to
the saw and/or kickback.
Follow the grinding and maintenance instruc-
tions for the chainsaw in this manual.
Decreasing the depth stop height can lead to
an increased risk of kickback.
Before starting the saw, make sure that the
chain is in proper operating condition and that
its condition complies with safety regulations.
Check in particular:
that the deceleration brake works correctly;
that the guide bar and sprocket cover are
correctly fitted;
that the chain is sharpened and tensioned in
accordance with the regulations.
Do not switch on the saw if a protective cover
is attached to the chain. This may damage the
protective cover. Discarded broken parts of the
cover can cause personal injury or damage to
property.
Avoid use in hazardous environments. Do not
use the saw in humid or wet environments or
expose it to rain. If water enters the saw, the risk
of electric shock will increase.
Do not throw the battery into a fire. It can ex-
plode. Follow the instructions for ecological
disposal.
Do not open or deform the battery. The elec-
trolyte is corrosive and may damage the eyes
or irritate the skin. It is a toxic substance, do not
swallow it.
Do not charge the battery in rain or humid en-
vironments.
When handling the battery, always follow the
instructions, directions and warnings in the rel-
evant operating manual.

Warning: Do not touch the chain with bare hands. Always wear protective gloves.
Protective cover
The protective cover protects the chain from damage, e.g. during storage, and prevents injuries or
hazardous situations. It is important to do so after each use.
Take extra care when inserting or removing the protective cover to avoid injury from the chain. We
recommend wearing protective gloves.
1. Lift the cover bar.
2. Attach or remove the protective cover (Fig. C1).
3. Carefully fold down the cover strip (Fig. C2).
USE
15ENGLISH
Removing the chain
Warning: Take extra care when removing the chain after use, as both the chain and the guide bar
may be hot. They become hot during operation. This is a normal occurrence. In this case, let the saw
cool down.
1. Press the edge of the lock to release the chain and pull out the lever that is part of the lock (Fig.
D1).
2. Turn the lock counterclockwise until the sprocket cover is released (Fig. D2).
3. Carefully remove the sprocket cover.
4. Carefully remove the chain from the sprocket first and then from the guide bar. Then remove the
guide bar from the saw body (Fig. D3 - 1. Sprocket cover; 2. Saw body; 3. Chain; 4. Guide rail).
Attaching the chain
1. Before attaching the chain, make sure that it is fitted in the correct direction. There is a mark on
the chain that shows the direction (Fig. E1).
2. First, place one part of the chain on the guide bar (Fig. E2)
3. Then place the guide bar against the saw body and place the other part of the chain on the
sprocket (Fig. E3).
4. Finally, attach the guide bar to the saw body.
5. Replacing the sprocket cover. Make sure that the tabs on the inside of the cover fit into the holes
in the saw body (Fig. E4).
6. Turn the lock clockwise to secure the cover (Fig. E5). Then return the lever to its original position
(Fig. E6).
Adjusting the chain tension
Warning: Adjust the chain tension in a clean environment. Avoid dusty or polluted environments.
Do not overtighten the chain. Excessive tension can cause the chain to break and damage the guide
bar and saw.
Warning: A loose chain can fall off the guide bar and cause serious injury. Always make sure that the
chain is correctly fitted and not overtightened or stretched.
The chain may come loose during use, so it is important to check regularly check the tension.
1. Press the edge of the lock to release the chain and pull out the lever that is part of the lock (Fig.
F1).
2. Turn the lock counterclockwise and slightly release the sprocket cover.
3. The chain head screw is used to adjust the chain tension. Tighten the chain by turning the screw
clockwise; loosen the chain by turning the screw counterclockwise (fig. F2).
4. To check that the chain is correctly tensioned, pull it with 1 kg of force. If the distance between
the inside of the chain and the guide bar is 3 to 4 mm, the chain is correctly tensioned (Fig. F3).
If the distance is less than 3 mm, the chain is too tight and needs to be released. If the distance is
greater than 4 mm, the chain is loose and must be tightened.
5. Once the chain is properly tensioned, turn the lock clockwise to secure the cover. Then return the
lever to its original position.
Checking the brake deceleration
Check the coasting brake before each use. This brake is part of the saw's safety system, which pro-
tects the operator from serious injury and damage to the saw.
1. Switch on the saw according to the instructions in the "On/Off" section.
USE
16 ENGLISH
2. Release the switch. The saw chain must stop within one second of releasing the switch. If this
happens, the coasting brake is good and it is safe to use the saw. If the saw chain does not stop
within one second, remove the battery and contact an authorized service centre to have the saw
repaired and adjusted. In this case, never use the saw.
Checking the cover strip
Checking the cover strip is important to prevent kickback. The shape of the cover strip with a protec-
tive tip is designed to eliminate kickback.
Regularly check the condition of the cover bar for damage, deformation, breakage, etc. Never use
a saw with a damaged cover bar. There is a risk of serious injury.
Lubrication
Only use commercially available biodegradable chain saw oils recommended by the manufacturer
or specified as appropriate to lubricate the chain. Do not use engine oils, waste oils or mineral oils.
Lubricate before each use of the saw.
1. Press the edge of the lock to release the chain and pull out the lever that is part of the lock (Fig.
D1).
2. Turn the lock counterclockwise until the sprocket cover is released (Fig. D2). Carefully remove the
sprocket cover.
3. Apply oil to the chain and sprocket. Use an oiler for application. Always apply a reasonable
amount. Too little or too much oil can adversely affect the saw's performance and the result of
its use.
4. Replacing the sprocket cover. Make sure that the tabs on the inside of the cover fit into the holes
in the saw body (Fig. E4).
5. Turn the lock clockwise to secure the cover (Fig. E5). Then return the lever to its original position
(Fig. E6).
Note: If the saw makes a rattling sound, the chain must be lubricated.
OPERATION
Intended use
This saw is intended only for personal use in the workshop, garden, etc. It is designed for cutting
branches, slats, and hard and soft wood. It is suitable for direct cutting. Do not use it for commercial
or other purposes.
Switching On/Off
Before switching on the saw, make sure that:
It is properly assembled and adjusted;
All bolts and nuts are fully tightened;
The battery is inserted correctly;
The battery is fully charged.
For safety reasons, the saw is fitted with a safety switch that prevents it from starting unintentionally.

USE
17ENGLISH
force the switch without first depressing the safety catch.
Cutting
Before switching on, first, place the protective plate against the edge of the workpiece to be cut.
Otherwise, the guide bar may vibrate, which could cause injury to the operator.
Switch on the saw. Cut the desired object by pushing lightly on the saw and sliding it down. The chain
speed should not decrease during cutting. The speed should remain constant.
If the chain speed decreases, reduce the pressure on the saw and the speed at which the saw moves.
If it is not possible to cut the object with a single cut, pull the saw back slightly and then continue
cutting.
Stand upright and steady when cutting. Keep your balance throughout the cutting process. Do not
lean, bend or stand on one leg, etc.
Do not handle the cover bar while the saw is in operation. There is a risk of serious injury.
Do not put your hands over the cover strip or under the protective plate. There is a risk of serious
injury.
Do not cut if the chain is in contact with the workpiece as it may hit a foreign object. There is a risk of
serious injury.
Loosen the workpieces before fastening them. Remove all foreign objects such as nails, screws, etc.
Keep body parts out of the reach of the saw, especially the chain, while it is in operation.
Always hold the saw with both hands.
When cutting a branch that stretches, pay attention to it springing back. When the tension in the
wood fibres is released, the sprung branch can hit the operator and/or you may lose control of the
saw.
Take extra care when cutting shrubs and young trees. Thin branches can catch on the chain, which can
throw them towards the operator or throw the operator off balance.
Do not overthrow or throw the saw.
Do not cover the ventilation holes.
Carrying the saw
When carrying the saw, always turn it off first and remove the battery. Then put on the chain guard.
Warning: Never carry a switched-on saw.
Overload protection
If using the saw in a way that uses an abnormally high current, the saw will automatically stop with-
out any indication. If this happens, release the switch to turn off the saw and stop the operation that
caused it to overload. Then turn it on again.
Overheating protection
If the saw or battery overheats, the saw will automatically stop. If this happens, release the switch to
turn off the saw and let the battery cool down. Then switch it on again.
Protection against excessive discharge
If the charge level drops excessively, the saw will automatically stop. If this happens, release the
switch to turn off the saw. Remove the battery and charge it.
Note: The saw and battery safety systems protect against overload, overheating and over-discharge.
Do not attempt to bypass or modify these security features. There is a risk of serious injury or death.
MAINTENANCE AND STORAGE
Warning: Before any maintenance or cleaning of the saw, always make sure that it is switched off and
the battery is removed.
The user must only carry out the maintenance and cleaning described in this manual. In the case of
further maintenance, cleaning or adjustment, contact an authorized service centre.
USE
18 ENGLISH
Clean the saw after each use. This will ensure its long service life.
Wear protective gloves when handling the chain.
Warning: Do not immerse any part of the saw in water or other liquids. Do not use a hose or pressure
washer for cleaning. Do not expose the saw to dripping or splashing water.
Remove any dirt from the ventilation holes. Use a dry cloth. Do not allow water to enter the ventilation
holes. There is a risk of damage to the motor unit.
Warning: Do not use petrol, thinner, alcohol or other similar substances for cleaning. There is a risk
of surface damage, deformation or cracking.
Chain grinding
The chain must be sharpened when:
The structure of sawdust has changed, and it is powdery;
more pressure needs to exerted when cutting;
it is not possible to cut straight;
the saw excessively vibrates.
A blunt chain must be sharpened. Use a chain grinder to grind the chain. Make sure the grinding
angle is 30°. If in doubt, have the chain sharpened by an authorized service centre.
If the chain is damaged, it must be replaced. Contact an authorized service centre.
Cleaning the guide rail
Sawdust and wood chips can accumulate in the groove of the guide rail. These can block the guide
rail groove and impair oil flow. Regularly remove sawdust and wood chips (Fig. H).
Cleaning the sprocket cover
Sawdust and wood chips can accumulate inside the sprocket cover. Remove the cover and clean the
interior (Fig. I).
Sprocket Replacement
If the sprocket is damaged or shows signs of damage, it must be replaced. A damaged sprocket can
also damage a new chain, so check the condition of the sprocket before fitting a new chain (Fig. J).
1. First loosen and remove the retaining ring and then the sprocket (Fig. K: 1. Retaining ring; 2.
Sprocket)
2. Then fit a new sprocket and retaining ring. When replacing, replace both parts at the same time.
Regular maintenance instructions
To prolong the life of the saw, prevent damage and ensure full functionality and safe use, it is neces-
sary to perform regular maintenance. Warranty claims can only be accepted if maintenance is per-
formed regularly and properly. Failure to perform the prescribed maintenance steps can lead to ac-
cidents! Chainsaw operators must not perform maintenance that is not described in these operating
instructions. All such operations must only be performed by an authorized service centre.
