2 GENERAL POWER TOOL
SAFETY WARNINGS
WARNING
Read all safety warnings and all instructions. Failure to
follow the warnings and instructions may result in electric
shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your battery-
operated (cordless) power tool.
2.1 WORK AREA SAFETY
•Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
•Do not operate power tools in explosive atmospheres,
such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
•Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
2.2 ELECTRICAL SAFETY
•Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
2.3 PERSONAL SAFETY
•Stay alert, watch what you are doing and use common
sense when operating a power tool. Do not use a
power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in
serious personal injury.
•Use personal protective equipment. Always wear eye
protection. Protective equipment such as a dust mask,
non-skid safety shoes, hard hat or hearing protection used
appropriately will reduce personal injuries.
•Prevent unintentional starting. Ensure the switch is in
the off position before connecting to power source
and/or battery pack and when picking up or carrying
the tool. Carrying power tools with your finger on the
switch or energizing power tools that have the switch on
invites accidents.
•Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal
injury.
4
English
EN

•Do not over-reach. Keep proper footing and balance
at all times. This enables better control of the power tool
in unexpected situations.
•Dress properly. Do not wear loose clothing or jewelry.
Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewelry or long hair can be
caught in moving parts.
•If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection can
reduce dust related hazards.
•Do not let familiarity gained from frequent use of tools
allow you to become complacent and ignore tool safety
principles. A careless action can cause severe injury
within a fraction of a second.
2.4 POWER TOOL USE AND CARE
•Do not force the power tool. Use the correct power
tool for your application. The correct power tool will do
the job better and safer at the rate for which it was
designed.
•Do not use the power tool if the switch does not turn it
on and off. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired.
•Disconnect the plug from the power source and/or
remove the BATTERY pack, if detachable, from the
power tool before making any adjustments, changing
accessories, or storing power tools . Such preventive
safety measures reduce the risk of starting the power tool
accidentally.
•Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool or
these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
•Maintain power tools and accessories. Check for
misalignment or binding of moving parts, breakage of
parts and any other condition that may affect the
power tool's operation. If damaged, have the power
tool repaired before use. Many accidents are caused by
poorly maintained power tools.
•Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
•Use the power tool, accessories and tool bits etc. in
accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
•Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
2.5 BATTERY TOOL USE AND CARE
•Recharge only with the charger specified by the
manufacturer. A charger that is suitable for one type of
battery pack may create a risk of fire when used with
another battery pack.
•Use power tools only with specifically designated
battery packs. Use of any other battery packs may create
a risk of injury and fire.
•When battery pack is not in use, keep it away from
other metal objects like paper clips, coins, keys, nails,
screws, or other small metal objects that can make a
connection from one terminal to another. Shorting the
battery terminals together may cause burns or fire.
•Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from the
battery may cause irritation or burns.
•Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behavior resulting in fire, explosion or risk
of injury.
•Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 130°C may cause explosion.
•Follow all charging instructions and do not charge the
battery pack or tool outside the temperature range
specified in the instructions. Charging improperly or at
temperatures outside the specified range may damage the
battery and increase the risk of fire.
2.6 SERVICE
•Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
•Never service damaged battery packs. Service of
battery packs should only be performed by the
manufacturer or authorized service providers.
3 SAFETY INSTRUCTIONS FOR
CHAIN SAWS
3.1 CHAINSAW SAFETY WARNINGS
•Keep all parts of the body away from the saw chain
when the chainsaw is operating. Before you start the
chainsaw, make sure the saw chain is not in contact
with anything. A moment of inattention while operating
chainsaws may cause entanglement of your clothing or
body with the saw chain.
•Hold the power tool by insulated gripping surfaces
only, because the saw chain may contact hidden
wiring. Saw chains contacting a “live” wire may make
exposed metal parts of the power tool “live” and could
give the operator an electric shock.
•Always hold the chainsaw with your right hand at the
rear handle and your left hand at the front handle.
Holding the chainsaw with a reversed hand configuration
increases the risk of personal injury and should never be
done.
5
English EN

•Wear safety glasses and hearing protection. Further
protective product for head, hands, legs and feet is
recommended. Adequate protective clothing will reduce
personal injury from flying debris or accidental contact
with the saw chain.
•Do not operate a chainsaw in a tree. Operation of a
chainsaw while up in a tree may result in personal injury.
•Always keep proper footing and operate the chainsaw
only when standing on fixed, secure and level surface.
Slippery or unstable surfaces such as ladders may cause
loss of balance or control of the chainsaw.
•When cutting a limb that is under tension, be alert of
spring back. When the tension in the wood fibres is
released, the spring loaded limb may strike the operator
and/or throw the chainsaw out of control.
•Use extreme caution when cutting brush and saplings.
The slender material may catch the saw chain and be
whipped toward you or pull you off balance.
•Carry the chainsaw by the front handle with the
chainsaw switched off and away from your body.
When transporting or storing the chainsaw, always fit
the guide bar cover. Proper handling of the chainsaw
will reduce the likelihood of accidental contact with the
moving saw chain.
•Follow instructions for lubricating, chain tensioning
and changing accessories. Improperly tensioned or
lubricated chain may either break or increase the chance
for kickback.
•Keep handles dry, clean, and free from oil and grease.
Greasy, oily handles are slippery, causing loss of control.
•Cut wood only. Do not use chainsaw for purposes not
intended. For example: do not use chainsaw for
cutting plastic, masonry or non-wood building
materials. Use of the chainsaw for operations other than
intended could result in a hazardous situation.
•Fatigue causes carelessness. Be more cautious before
rest periods and towards the end of your shift.
•Personal protective clothing required by your safety
organizations, government regulations, or your
employer should be used. At all times when using a
chain saw, snug-fitting clothing, protective eyewear,
safety footwear, and hand, leg, and hearing protection
should be worn.
•Before fuelling, servicing, or transporting your chain
saw, switch off the chain saw.
•When felling, keep at least two tree lengths away from
other persons or animals.
•Plan your work, ensuring an obstacle-free work area
and, in the case of felling, have at least one escape
path from the falling tree prepared in advance.
•Follow the instructions in your operator’s manual for
starting the chain saw and control the chain saw with
a firm grip on both handles when it is in operation.
Always hold the chain saw with your right hand on the
rear handle and your left hand on the front handle. Keep
handles dry, clean, and free of oil.
•When transporting your chain saw, use the
appropriate transportation covers, which should be
available for the guide bar and saw chain.
•Never operate a chain saw that is damaged or
improperly adjusted or that is not completely and
securely assembled. Be sure that the saw chain stops
moving when the power control system trigger is
released. Never adjust the guide bar or saw chain when
the chain saw is operating.
•Do not attempt a pruning or limbing operation in a
standing tree unless specifically trained to do so.
•Guard against kickback. Kickback is the upward
motion of the guide bar that occurs when the saw
chain, at the nose of the guide bar, contacts an object.
Kickback can lead to dangerous loss of control of the
chain saw.
•A chain saw is intended for two-handed use. Serious
injury to the operator, helpers, and/or bystanders can
result from one-handed operation.
3.2 CAUSES AND OPERATOR
PREVENTION OF KICKBACK:
Kickback may occur when the nose or tip of the guide bar
touches an object, or when the wood closes in and pinches the
saw chain in the cut.
Tip contact in some cases may cause a sudden reverse
reaction, kicking the guide bar up and back towards the
operator.
Pinching the saw chain along the top of the guide bar may
push the guide bar rapidly back towards the operator.
Either of these reactions may cause you to lose control of the
saw which could result in serious personal injury. Do not rely
exclusively upon the safety devices built into your saw. As a
chainsaw user, you should take several steps to keep your
cutting jobs free from accident or injury.
Kickback is the result of tool misuse and/or incorrect
operating procedures or conditions and can be avoided by
taking proper precautions as given below:
•Maintain a firm grip, with thumbs and fingers
encircling the chainsaw handles, with both hands on
the saw and your body and arm positioned to allow
you to resist kickback forces.
Kickback forces can be controlled by the operator, if
proper precautions are taken. Do not let go of the
chainsaw.
•Do not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact and
enables better control of the chainsaw in unexpected
situations.
•Only use replacement bars and chains specified by the
manufacturer. Incorrect replacement bars and chains
may cause chain breakage and/or kickback.
•Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.

4. Call approved service center for repair before use if
• The chain brake does not stop the chain immediately.
• The chain brake does not stay in the disengaged
position without aid.
9.6 PREPARE TO CUT THE TREE
IMPORTANT
Do not work alone when you are working at height from a
rope and harness. You must:
• get help from a ground worker trained in applicable
emergency procedures.
• be trained in general safe climbing and work
positioning techniques.
• have correct harnesses, ropes, strops, carabiners and
other equipment.
Examine, charge up, start and warm up the machine.
Switch off the machine before you send it up to the operator
in the tree.
Make sure that the machine has a correct strop for attachment
to the harness.
• Secure the strop around the attachment point on the rear
of the saw.
• Attach the machine to the harness directly or indirectly
with correct carabiner.
• Make sure that the machine is safely attached when it is
being sent up to the operator.
• Make sure that the machine is secured to the harness
before it stops rising.
• Always switch the machine off when it is directly
attached to the harness.
Attach the machine to the recommended attachment points on
the harness (mid-point or at the sides).
When changing the attachment point to another, make sure
that the machine is secured in the new position before
releasing the previous attachment point.
9.7 THE WORK POSITION FOR TWO-
HANDED USE
NOTE
An analysis of accidents with the machine during tree
service operations shows the primary cause is inappropriate
one-handed use of the machine. In the vast majority of
accidents, operators do not use a safe work position that let
them hold both handles of the machine. Not hold the
machine firmly results in an increased risk of injury. If it
kicks back, it is more likely to touch climbing lines and the
operator’s body (particularly the left hand and arm).
• To use the machine with both hands, as a general rule
operators must aim for a safe work position in:
• hip level, when cutting horizontal sections, and
• solar plexus level, when cutting vertical sections.
• When operator is working close into vertical stem with
low lateral forces on the work position, a good footing
could be all that is needed to maintain a safe work
position.
• When operators move away from the stem, it is necessary
to remove or counteract the increasing lateral forces by
• a redirect of the main line via a supplementary anchor
point, or
• use of an adjustable strop direct from the harness to
supplementary anchor point.

9.8 START THE MACHINE IN THE
TREE
1. Apply the chain brake before starting.
2. Hold the machine with your left hand on the front handle.
3. Thrust the machine away from your body while holding
the pull starter cord in your right hand.
4. Hold the machine with your right hand on either handle.
5. Thrust the machine away from your body while holding
the pull starter cord in your left hand.
NOTE
• The chain brake must always be engaged before a
running machine is lowered onto its strop.
• Examine that the machine has sufficient energy before
doing critical cuts.
9.9 OPERATE THE MACHINE WITH
ONE HAND
NOTE
Do not use the machine with one hand when work position
is unstable or in preference to a handsaw when cutting small
diameter wood at the branch tips.
Operate the machine with one hand only when:
• You cannot get a work position enabling two-handed
operation.
• You need to support the working position with one hand.
• The machine is being used at full stretch, at right angles
to and out of line with your body.
Do not:
• Cut with the kickback zone at the tip of the saw guide bar.
• "Hold and cut" sections, or.
• Attempt to catch falling sections.
9.10 FELL A TREE
23
24
24
25
25
It is recommended that the first-time user should, as a
minimum practice, start cutting logs on a saw-horse or cradle.
Before you start to fell a tree, make sure that:
• The minimum distance between the areas of bucking and
felling performed by two or more persons at the same
time is two times the height of the tree felled.
• The operation does not:
• Cause injury to personnel.
• Hit utility lines. If the tree touches utility lines,
immediately tell the utility company.
• Cause losses in property.
• The user is not in the danger area (24), for example, the
downhill side of the area.
• The escape paths (25) that extend back and diagonally
behind the felling direction (23) are clear. The felling
direction is controlled by:
• The natural lean of the tree.
• The location of larger branches.
• The wind direction.
• Ensure there is no dirt, stones, loose bark, nails, or staples
on the tree.

English EN

1. Make a lower level notching cut (27). Make sure that
this cut is:
a) 1/3 width of the diameter of the tree.
b) Perpendicular to the felling direction.
CAUTION
The level notching cut helps prevent pinching of the
saw chain or the guide bar when you make the second
notch.
2. Make the felling cut (28) no less than 2 in. (50 mm) or
higher than the level notching cut. Make sure that this
cut:
a) Is parallel to the level notching cut.
b) Keeps sufficient wood 2 in. (50 mm) or 1/10 the
diameter of the tree to become a hinge (29) which
prevents the tree from twisting and felling in the
wrong direction.
When the felling cut (28) gets near the hinge (29), the tree
falls. Stop the felling cut if the tree:
• Does not fall in the correct direction or
• Moves backwards, causing the cutting bar and chain
to become stuck in the cut.
3. Use felling wedge to open the cut and let the tree fall
in the correct direction.
4. When the tree starts to fall:
a) Remove the chainsaw from the cut.
b) Stop the machine.
c) Put the machine down.
d) Move away from the tree via the escape path (25).
Always keep watching the tree to see the direction of
fall. Be careful with overhead branches and your
footing.
9.11 LIMB A TREE
30
31
Limbing is the removal of the branches from a fallen tree.
1. Keep the larger lower branches to hold the log off the
ground (31).
2. Remove the small limbs (30) in one cut.
3. Limb the branches with tension from the bottom to top.
4. Keep the larger lower branches as a support until the log
is limbed.
9.12 BUCK A LOG
To buck is to cut a log into lengths.
CAUTION
Do not let the chainsaw touch the ground.
It is important to make sure your footing is secure and your
weight is evenly distributed. If possible, lift the log and hold
it with branches, logs or chock. Obey the instructions below:
33
32
When the log is held along the full length (32), cut it from the
top (33).
34
36
35
When the log is held on one end (34):
1. Cut the first time 1/3 of the diameter from the bottom
(35).
2. Cut the second time from the top (36) to complete the
bucking.
36
37 35
When the log is held on two ends (37):
1. Cut the first time 1/3 of the diameter from the top (36).
2. Cut the second time lower 2/3 from the bottom to
complete the bucking (35).
12
English
EN

38
39
When the log is on a slope:
1. Stand on the uphill side.
2. Control the chainsaw completely.
3. Hold the chainsaw handles tightly.
4. Release the cutting pressure near the end of the cut.
When bucking is complete (38):
1. Wait for the chain to stop (39).
2. Ensure the chainsaw is turned off.
3. Check for hazards before you move to another tree.
10 MAINTENANCE
CAUTION
Do not let brake fluids, gasoline, petroleum-based materials
touch the plastic parts. Chemicals can cause damage to the
plastic, and make the plastic unserviceable.
CAUTION
Do not use strong solvents or detergents on the plastic
housing or components.
WARNING
Remove the battery pack from the machine before
maintenance.
10.1 REPLACE THE GUIDE BAR AND
THE CHAIN

English EN

11. Tighten the nuts when the chain is correctly tensioned.
NOTE
If you start the chain saw with a new chain, have a test for
2-3 minutes. A new chain gets longer after the first use,
examine the tension and tighten the chain if necessary.
10.2 ADJUST THE CHAIN TENSION
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up the
slack.
Tension the chain so that it can only just be pulled away from
the bar at its centre point.
WARNING
A slack chain may jump off and cause serious or even fatal
injury.
CAUTION
Wear protective gloves if you touch the chain, bar or areas
around the chain.
1. Stop the machine.
2. Loosen the lock nuts with the wrench.
NOTE
It is not necessary to remove the chain cover to adjust the
chain tension.
3. Turn the chain adjustment screw clockwise to increase
the chain tension.
4. Turn the chain adjustment screw counterclockwise to
decrease the chain tension.
5. When the chain is at the wanted tension, tighten the lock
nuts.
NOTE
During normal saw operation, the temperature of the chain
increases. The drive links of a correctly tensioned warm
chain will hang approximately 1/16 in. (1,58 mm) out of the
bar groove.
1/16 in. (1,58 mm)
10.3 SHARPEN THE CUTTERS
Sharpen the cutters if chain does not go into wood easily.
NOTE
We recommend that a service center, which has an electric
sharpener, perform important sharpening work.
1. Tensioning chain.
2. Sharpen the cutters corner with a 5/32 in. (4 mm)
diameter round file .
3. Sharpen the top plate, side plate and depth gauge with a
flat file.
14
English
EN

4. File all the cutters to the specified angles and the same
length.
NOTE
During the process:
• Keep the file flat with the surface to be sharpened.
• Use the midpoint of the file bar.
• Use light but firm pressure when sharpening the
surface.
• Lift the file away on each return stroke.
• Sharpen the cutters on one side and then move to the
other side.
Replace the chain if:
• The length of the cutting edges is less than 1/5 in. (5
mm).
• There is too much space between the drive links and the
rivets.
• The cut speed is slow.
• Sharpening the chain many times but it does not increase
the cutting speed. The chain is worn.
10.4 GUIDE BAR MAINTENANCE
NOTE
Make sure that the bar is turned over periodically to keep
symmetrical wear on the bar.
1. Lubricate the bearings on the nose sprocket (if present)
with the syringe (not included).
2. Clean the bar groove with the scraping hook (not
included).
3. Clean the lubrication holes.
4. Remove burr from the edges and level the cutters with a
flat file.
Replace the bar if:
• the groove does not fit with the height of the drive links
(which must never touch the bottom).
• the inside of the guide bar is worn and makes the chain
lean to one side.
11 TRANSPORTATION AND
STORAGE
Before you move the machine, always
• Remove the battery pack from the machine.
• Keep hands clear of the lock-out button.
• Put the scabbard on the guide bar and the chain.
Before you put the machine into storage, always
• Remove all residual oil from the machine.
• Remove the battery pack from the machine.
• Clean all unwanted material from the machine.
• Make sure that the storage area is
• Not available to children.
• Away from agents which can cause corrosion, such as
garden chemicals and de-icing salts.
