3 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 mains-operated (corded) power tool or
battery-operated (cordless) power tool.
3.1 Work area safety
■Keep work area clean and well lit. Cluttered
and 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.
3.2 Electrical safety
■Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs
and matching outlets will reduce the risk of
electric shock.
■Avoid body contact with earthed or
grounded surfaces such as pipes,
radiators, ranges and refrigerators. There
is an increased risk of electric shock if your
body is earthed or grounded.
■Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
■Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil,
sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric
shock.
■When operating a power tool outdoors,
use an extension cord suitable for
outdoor use. Use of a cord suitable for
outdoor use reduces the risk of electric
shock.
■If operating a power tool in a damp
location is unavoidable, use a residual
current device (RCD) protected supply.
Use of an RCD reduces the risk of electric
shock.
3.3 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 for appropriate conditions will reduce
personal injuries.
■Prevent unintentional starting. Ensure the
switch is in the off-position before
connecting to power source and/or
battery pack, picking up or carrying the
tool. Carrying power tools with your finger on
the switch or energising 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.
■Do not overreach. 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 jewellery. Keep your hair,
clothing and gloves away from moving
parts. Loose clothes, jewellery 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 these devices can reduce dust-
related hazards.
3.4 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

10 CS 4030
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 the battery pack 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. 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.
3.5 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
paperclips, 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 a 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 form the
battery may cause irritation or burns.
3.6 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.
4 CHAIN SAW SAFETY WARNINGS
■Keep all parts of the body away from the
saw chain when the chain saw is
operating. Before you start the chain saw,
make sure the saw chain is not contacting
anything. A moment of inattention while
operating chain saws may cause
entanglement of your clothing or body with
the saw chain.
■Always hold the chain saw with your right
hand on the rear handle and your left
hand on the front handle. Holding the chain
saw with a reversed hand configuration
increases the risk of personal injury and
should never be done.
■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.
■Wear safety glasses and hearing
protection. Further protective equipment
for head, hands, legs and feet is
recommended. Adequate protective clothing
will reduce personal injury by flying debris or
accidental contact with the saw chain.
■Do not operate a chain saw in a tree.
Operation of a chain saw while up in a tree
may result in personal injury.
■Always keep proper footing and operate
the chain saw only when standing on
fixed, secure and level surface. Slippery or
unstable surfaces such as ladders may
cause a loss of balance or control of the
chain saw.

11
■When cutting a limb that is under tension
be alert for spring back. When the tension
in the wood fibres is released the spring
loaded limb may strike the operator and/or
throw the chain saw 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 chain saw by the front handle
with the chain saw switched off and away
from your body. When transporting or
storing the chain saw always fit the guide
bar cover. Proper handling of the chain saw
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 chains
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 chain saw for
purposes not intended. For example: do
not use chain saw for cutting plastic,
masonry or non-wood building materials.
Use of the chain saw for operations other
than intended could result in a hazardous
situation.
5 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 chain saw
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 chain saw handles, with both
hands on the saw and position your body and
arm 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 chain saw.
■Do not overreach and do not cut above
shoulder height. This helps prevent
unintended tip contact and enables better
control of the chain saw 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.
Decreasing the depth gauge height can lead
to increased kickback.
6 VIBRATION LOAD
WARNING!
Danger due to vibration
The actual magnitude of the vibration
emissions during the use of the
appliance may deviate from that stated
by the manufacturer. Observe the
following influencing factors before or
during use:
■Is the appliance being used as
intended?
■Is the material being cut or
processed in the proper manner?
■Is the appliance in a proper
condition of use?
■Is the cutting tool properly
sharpened or is the correct cutting
tool installed?
■Are the handle grips and any
optional vibration grips mounted,
and are they firmly attached to the
appliance?
■Only operate the tool at the motor speed
required for the respective work. Avoid using
the maximum speed in order to reduce noise
and vibrations.

12 CS 4030
■The noise and vibrations of the tool may
increase due to improper use and
maintenance. This leads to health damage.
In this case, immediately switch off the tool
and have it repaired by an authorised service
workshop.
■The degree of stress due to vibration
depends on the work to be performed or on
the use of the tool. Estimate the stress and
plan appropriate work breaks. This
considerably reduces stress due to vibration
over the entire working time.
■Extensive use of the tool exposes the
operator to vibrations, which can lead to
circulatory issues (“white fingers”). To avoid
this risk, wear gloves and keep your hands
warm. If any symptoms of “white fingers”
occur, immediately consult a physician.
These symptoms include: Numbness, loss of
feeling, tingling, itching, pain, reduced
muscular strength, changes in the colour or
condition of the skin. Normally these
conditions affect the fingers, hands or pulse.
The risk increases at low temperatures.
■Take long breaks during your working day so
you can recover from the noise and the
vibrations. Plan your work in such a way that
the use of appliances that generate strong
vibrations is spread over several days.
■If you notice an unpleasant sensation or
discolouration of the skin on your hands
when using the tool, stop work immediately.
Take sufficient work breaks. Without
sufficient breaks, a hand/arm vibration
syndrome can occur.
■Minimise your risk of being exposed to
vibrations. Maintain the tool according to the
instructions in the operating instructions.
■If the tool is used frequently, contact your
dealer to purchase anti-vibration accessories
(e.g. handles).
■Avoid working with the tool at temperatures
below 10 °C. Define how the vibration load
can be limited in a work plan
7 NOISE POLLUTION
A certain level of noise exposure from this
appliance is inevitable. Carry out noisy work at
approved and specified time periods. Observe
rest periods as necessary and restrict the
duration of the work to a minimum. For your
personal protection and protection of persons in
the vicinity, appropriate hearing protection must
be worn.

12.8 Filling saw chain oil (09 - Page 7)
IMPORTANT!
Danger of damaging the chain saw
The chain saw will be severely damaged
if there is too little or even no saw chain
oil in the tank or it has dried/is sticky.
Dried/sticky saw chain oil can lead to
damage to oil-channelling components
or the oil pump.
Damage also occurs if used oil is used.
The use of used oil leads to
environmental damage!
■For start-up work, fill saw chain oil
into the tank.
■Do not use any used oil!
■Each time before changing the
rechargeable battery at the latest, fill
the tank with saw chain oil again.
The saw chain and the chain bar are continuously
supplied with oil during operation by means of an
automatic oiler system. The saw chain oil
protects against corrosion and premature wear.
There must always be sufficient saw chain oil in
the tank to lubricate the saw chain sufficiently.
To lubricate the saw chain and the chain bar,
only use environmentally friendly, biodegradable,
high-quality saw chain oil. This oil must be
transported and stored in approved and
appropriately labelled containers.
Each time before starting work or changing the
rechargeable battery, check the oil level and
replenish the saw chain oil if necessary:
1. Check the oil level in the viewing aperture of
the tank (09/1). It must always be possible to
see oil. The minimum and the maximum oil
level must not be exceeded.
2. Refill saw chain oil via the filler neck (09/2) if
necessary.

14 WORKING BEHAVIOUR AND
WORKING TECHNIQUE
NOTE
Courses in the use of chain saws and
techniques for felling trees are regularly
held by various forestry organisations.

19
DANGER!
Danger of fatal injury due to
inadequate technical knowledge!
Inadequate technical knowledge can
result in extremely serious up to fatal
injury!
■Only trained and experienced
people are allowed to fell trees and
lop branches.
DANGER!
Danger of fatal injury from splintered
wood!
Wood chips caught up in the chain can
cause extremely serious and even fatal
injury!
■Remove loose chips and wood
splinters from the part to be sawn.
14.1 Felling trees (17,18 - Page 8)
Take the following measures before starting
felling work.
■ Makesurethatnootherpeople,animalsor
objects are in the danger area.
■ Thesafedistancefromotherworkplacesor
objects should be at least 2½ tree lengths.
■ Watchoutforpowerlinesandotherpeople’s
property. If necessary, notify the power
supply company or the property owner.
■ Judgethefallingdirectionofthetree.
Factors influencing the falling direction of the
tree:
■Natural lean of the tree
■Height of the tree
■Branches growing on one side
■Level ground or slope
■Asymmetrical growth, wood damage
■Wind direction and wind speed
■Snow load
■When working on a slope, always work uphill
of the tree to be felled.
■Establish your escape route in advance, and
make sure that there are no obstacles in the
way. The escape route should be at an angle
of approx. 45° backwards from the falling
direction (17).
■The trunk must be free from growth,
branches and foreign bodies (e.g. dirt,
stones, loose bark, nails, staples, wire, etc.).
Make two undercuts and one back cut in order to
fell a tree.
1. During back cuts and cross-cuts, place the
bumper spike firmly against the wood to be
cut.
2. Saw the first undercut (18/C) horizontally,
then the second undercut at an angle of at
least 45° from above. This prevents the chain
saw becoming trapped when you make the
second undercut. The undercut must be as
close as possible to the ground and in the
required felling direction (18/E). The depth of
the undercut should be about 1/4 of the
diameter of the trunk.
3. Cut the back cut (18/D) exactly horizontally
opposite to the undercut. The back cut must
be made 3-5 cm above the horizontal
undercut.
4. Saw in the back cut (18/D) sufficiently deep
so that a bridge (18/F) of at least 1/10 the
trunk diameter remains between the undercut
(18/C) and the back cut (18/D). This bridge
prevents the tree from twisting and falling in
the wrong direction. The tree should start to
fall when the back cut (18/D) approaches the
bridge (18/F).
If the tree falls whilst you are sawing:
■Interrupt the back cut if the tree does fall
in the wrong direction or leans back and
traps the chain saw. To open the cut and
fell the tree, drive in wedges in the
direction of the required felling line.
■Immediately pull the chain saw from the
cut, switch it off and put it down.
■Walk away in the direction of the escape
route.
■Watch out for falling branches and twigs.
5. If the tree remains standing, drive wedges
into the back cut in order to cause it to fall in
a controlled way.
6. At the end of sawing work, immediately
remove your ear protection and listen out for
signals or warning calls.
NOTE
Only use wedges made from wood,
plastic or aluminium.

20 CS 4030
DANGER!
Danger of fatal injury from a falling
tree!
Having no escape route when felling a
tree represents a danger of serious and
even fatal injury!
■Do not start the felling work until you
are sure there is an unobstructed
escape route away from the tree to
be felled.
DANGER!
Danger of fatal injury from an
uncontrollably falling tree!
Uncontrolled falling trees can lead to
extremely serious and even fatal injury!
■In order to guarantee controlled
felling of a tree, leave a bridge
between the undercut and the back
cut. The length of this bridge should
be approx. 1/10 of the trunk
diameter.
■Do not carry out any felling work in
windy conditions.
14.2 Branch lopping (19 - Page 8)
Heed the following points during this work:
■Support the chain saw against the tree trunk
during the work.
■In the preliminary phase, leave larger,
downward-pointing branches that are
supporting the tree (19).
■Cut off smaller branches with one cut.
■Pay attention to branches under tension, and
saw through these from underneath upwards
in order to avoid the chain saw becoming
trapped (19).
■Do not saw off free-hanging branches from
underneath.
■Only experienced or trained people should
make plunge cuts, longitudinal cuts and
boring cuts (18).
14.3 Cross-cutting
Heed the following points during this work:
■When working on a slope, always stand uphill
from the tree trunk, because it could roll away
(19).
■Guide the chain saw so that there is no part
of your body in the extended sweep arc of
the saw chain.
■Position the bumper spike directly adjacent to
the cut edge and allow the chain saw to pivot
about this point. Do not exert any pressure at
the end of the cut.
■Make sure that the saw chain does not touch
the ground.
■At the end of the cut, wait for the saw chain
to come to a halt before you remove the
chain saw.
■Always switch off the engine of the chain saw
before you go to the next tree.
The entire length of the tree trunk is in contact
with the ground:
■Saw through the tree trunk from above,
without cutting into the ground (20 - Page 8).
Tree trunk is lying raised at one end:
■To prevent the chain saw becoming trapped
and the wood splintering, first saw through
1/3 of the trunk diameter from below, then
saw through the remainder from above, down
as far as the cut made from underneath (10 -
Page 7).
Tree trunk is lying raised at both ends:
To prevent the chain saw becoming trapped and
the wood splintering, first saw through 1/3 of the
trunk diameter from above, then saw through the
remainder from underneath, up as far as the cut
made from above (11 - Page 7).
DANGER!
Danger of fatal injury due to kickback!
The operator can be fatally injured by
kickback of the appliance.
■It is essential to comply with the
measures in order to avoid any
kickback.
Sharpen the saw chain frequently, without
removing much material while doing so. After
sharpening 3 to 4 times yourself, have the saw
chain resharpened by a specialist workshop. This
also involves resharpening the depth limiter.
Renew the saw chain as soon as the minimum
cutting tooth length of 4 mm (13) is reached.
