General Power Tool Safety Warnings
WARNING Read all safety warnings, instruc-
tions, illustrations and specifica-
tions provided with this power tool. Failure to follow all in-
structions listed below 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 (cord-
less) power tool.
Work area safety
uKeep work area clean and well lit. Cluttered or dark
areas invite accidents.
uDo 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.
uKeep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
Electrical safety
uPower 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 risk of electric shock.
uAvoid body contact with earthed or grounded sur-
faces, such as pipes, radiators, ranges and refrigerat-
ors. There is an increased risk of electric shock if your
body is earthed or grounded.
uDo not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
uDo not abuse the cord. Never use the cord for carry-
ing, 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.
uWhen operating a power tool outdoors, use an exten-
sion cord suitable for outdoor use. Use of a cord suit-
able for outdoor use reduces the risk of electric shock.
uIf operating a power tool in a damp location is un-
avoidable, use a residual current device (RCD) protec-
ted supply. Use of an RCD reduces the risk of electric
shock.
Personal safety
uStay 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 inatten-
tion while operating power tools may result in serious per-
sonal injury.
uUse 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 in-
juries.
uPrevent 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 en-
ergising power tools that have the switch on invites acci-
dents.
uRemove 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 in-
jury.
uDo not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situations.
uDress properly. Do not wear loose clothing or jew-
ellery. Keep your hair and clothing away from moving
parts. Loose clothes, jewellery or long hair can be caught
in moving parts.
uIf devices are provided for the connection of dust ex-
traction and collection facilities, ensure these are con-
nected and properly used. Use of dust collection can re-
duce dust-related hazards.
uDo 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 in-
jury within a fraction of a second.
Power tool use and care
uDo 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 de-
signed.
uDo 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.
uDisconnect the plug from the power source and/or re-
move the battery pack, if detachable, from the power
tool before making any adjustments, changing ac-
cessories, or storing power tools. Such preventive
safety measures reduce the risk of starting the power tool
accidentally.
uStore 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.
uMaintain power tools and accessories. Check for mis-
alignment 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.
uKeep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
uUse the power tool, accessories and tool bits etc. in
accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
uKeep 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.
Battery tool use and care
uRecharge only with the charger specified by the manu-
facturer. A charger that is suitable for one type of bat-
tery pack may create a risk of fire when used with another
battery pack.
uUse power tools only with specifically designated bat-
tery packs. Use of any other battery packs may create a
risk of injury and fire.
uWhen 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 a fire.
uUnder abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally oc-
curs, flush with water. If liquid contacts eyes, addi-
tionally seek medical help. Liquid ejected from the bat-
tery may cause irritation or burns.
uDo not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or risk
of injury.
uDo not expose a battery pack or tool to fire or excess-
ive temperature. Exposure to fire or temperature above
130°C may cause explosion.
uFollow 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.
Service
uHave 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.
uNever service damaged battery packs. Service of bat-
tery packs should only be performed by the manufacturer
or authorized service providers.
General Chain Saw Safety Warnings
uKeep 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.
uAlways 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.
uHold the chain saw by insulated gripping surfaces
only, because the saw chain may contact hidden wir-
ing. Saw chains contacting a “live” wire may make ex-
posed metal parts of the chain saw “live” and could give
the operator an electric shock.
uWear eye protection. Further protective equipment
for hearing, head, hands, legs and feet is recommen-
ded. Adequate protective equipment will reduce personal
injury from flying debris or accidental contact with the
saw chain.
uDo not operate a chain saw in a tree, on a ladder, from
a rooftop, or any unstable support. Operation of a chain
saw in this manner could result in serious personal injury.
uAlways keep proper footing and operate the chain saw
only when standing on fixed, secure and level surface.
Slippery or unstable surfaces may cause a loss of balance
or control of the chain saw.
uWhen cutting a limb that is under tension be alert for
spring back. When the tension in the wood fibres is re-
leased the spring loaded limb may strike the operator
and/or throw the chain saw out of control.
F 016 L94 633 | (03.05.2023) Bosch Power Tools

English | 5
uUse 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.
uCarry 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 re-
duce the likelihood of accidental contact with the moving
saw chain.
uFollow instructions for lubricating, chain tensioning
and changing the bar and chain. Improperly tensioned
or lubricated chain may either break or increase the
chance for kickback.
uCut wood only. Do not use chain saw for purposes not
intended. For example: do not use chain saw for cut-
ting metal, plastic, masonry or non-wood building ma-
terials. Use of the chain saw for operations different than
intended could result in a hazardous situation.
uThis chain saw is not intended for tree felling. Use of
the chain saw for operations different than intended
could result in serious injury to the operator or bystand-
ers.
uFollow all instructions when clearing jammed mater-
ial, storing or servicing the chain saw. Make sure the
switch is off and the battery pack is removed. Unex-
pected actuation of the chain saw while clearing jammed
material or servicing may result in serious personal injury.
uCauses 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 oper-
ator.
– 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 in-
jury.
Kickback is the result of chain saw misuse and/or incor-
rect operating procedures or conditions and can be
avoided by taking proper precautions as given below:
uMaintain a firm grip, with thumbs and fingers encirc-
ling 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 con-
trolled by the operator, if proper precautions are taken.
Do not let go of the chain saw.
uDo not overreach and do not cut above shoulder
height. This helps prevent unintended tip contact and en-
ables better control of the chain saw in unexpected situ-
ations.
uOnly use replacement guide bars and saw chains spe-
cified by the manufacturer. Incorrect replacement
guide bars and saw chains may cause chain breakage
and/or kickback.
uFollow the manufacturer’s sharpening and mainten-
ance instructions for the saw chain. Decreasing the
depth gauge height can lead to increased kickback.
Additional safety warnings
uThis appliance is not intended for use by persons (in-
cluding children) with reduced physical, sensory or
mental capabilities, or lack of experience and know-
ledge, unless they have been given supervision or in-
struction concerning use of the appliance by a person
responsible for their safety. Children should be super-
vised to ensure that they do not play with the appliance.
uWhen working with the tool, always hold it firmly with
both hands and provide for a secure stance. The power
tool is guided more secure with both hands.
uAlways ensure all handles and guards are fitted when
using the machine. Never attempt to use an incomplete
machine or one fitted with an unauthorized modification.
uAlways operate the power tool with a properly aligned
and tensioned chain. Using the power tool with a mis-
aligned or incorrectly tensioned chain can result in chain
breakage, kickback and/or injury.
uAlways make sure that the chain is in the correct position.
An incorrectly positioned chain can result in chain break-
age, kickback and/or injury.

Mounting and Tensioning the Saw Chain (see
figuresB1 – B4)
uDo not use any tools for assembly.
uCheck the chain tension regularly during use. Using
the chainsaw with a misaligned or incorrectly tensioned
chain can result in chain breakage, kickback and/or in-
jury.
uUpon initial operation, new chains can lengthen con-
siderably.
uAvoid tensioning the chain if it is hot, as this will cause
the chain to become overtensioned and fit too tightly
against the chain bar when it cools down.
– Place the chain saw on any suitable flat surface.
– With the chain bar off the tool, make sure that the affixed
tensioning wheel(14) on the chain bar has been fully ro-
tated anticlockwise.
– Slide the saw chain (13) in the slot around the chain bar
(12).
– Ensure the saw chain is in the correct running direction by
comparing the saw chain with the rotation symbol (11).
– Fit the chain links around the drive sprocket (3) and
mount the chain bar (12) onto the fastening bolt (9).
– Check if all parts are seated properly and hold the chain
bar and the chain in this position.
– Then rotate the affixed tensioning wheel(14) clockwise
until the chain is partly tensioned and will stay mounted
to the chain saw.
– Attach the cover(17) and rotate the clamping knob(16)
clockwise until the cover is partly secured.
– Turn the chain-tensioning ring(15) clockwise until the
correct chain tension is reached. When adjusting with the
chain-tensioning ring(15), make sure to hold the clamp-
ing knob(16) to prevent it from turning and clamping too
early.
– The saw chain(13) is correctly tensioned when it can be
raised approx. 6−7mm from the chain bar in the centre.
This should be done by using one hand to raise the saw
chain against the weight of the machine.
– Once the correct tension is reached, hold the chain-ten-
sioning ring(15) and rotate the clamping knob(16)
clockwise until it is firmly secured.
– If the chain is tensioned too tightly, unscrew the clamping
knob(16) and repeat the steps for tensioning.
– The locking mechanism of the clamping system prevents
the chain from loosening. If the chain-tensioning ring(15)
is hard to rotate, loosen the clamping knob(16) by turn-
ing it anticlockwise.
Saw Chain Lubrication (see figure C)
Note: The chain saw is not supplied filled with oil. It is essen-
tial to fill with oil before use. Operating the chain saw
without chain oil or when the oil level is below the minimum
mark will result in damage to the chain saw.
Chain life and cutting capacity depend on optimum lubrica-
tion. Therefore, the chain is automatically lubricated with
chain oil during operation via the oil outlet (7).
Filling the oil reservoir:
– Set chain saw on any suitable surface with the oil filler cap
(19) facing upward.
– Clean area around the oil filler cap (19) with a cloth and
unscrew the cap.
– Add Bosch biodegradable chain saw oil until the oil level
can be viewed through the oil tank opening (25). Take
care when filling to avoid dirt or debris from entering the
oil tank. Screw on oil filler cap (19) again and tighten
fully.
Note: It is important to use only readily biodegradable chain
lubricants (according to RAL-UZ48) to avoid damage to the
chain saw. Never use recycled/old oil. Use of non approved
oil will invalidate the warranty.
Note: The oil filter is embedded inside the oil tank. Contact
the Bosch service centre for cleaning or troubleshooting.
Note: It is strongly recommended to use Bosch Biodegrad-
able chain oil. This can be seen in the accessories section.
Note: Oil becomes denser at lower temperatures which de-
creases the flow rate of oil.
Starting Operation
Inserting/removing the battery (see figureD)
Note: Using unsuitable batteries can lead to malfunctions or
damage the machine.
Insert the charged battery (21). Make sure that the battery
is fully fitted.
To remove the battery (21) from the machine, press the bat-
tery unlocking button (22) and pull the battery out.
Charging the Battery
uPay attention to the mains voltage. The voltage of the
power source must match the voltage specified on the
rating plate of the charger.
The battery is equipped with temperature monitoring that al-
lows charging only in the temperature range between 0 °C
and 35 °C. In this manner, a high battery service life is
achieved.
Note: The battery is supplied partially charged. To ensure
full battery capacity, completely charge the battery in the
battery charger before using for the first time.
The lithium-ion battery can be charged at any time without
reducing its service life. Interrupting the charging procedure
does not cause damage to the battery.
The “Electronic Cell Protection (ECP)” protects the lithium-
ion battery against deep discharging. When the battery is
empty, the product is switched off by means of a protective
circuit: The product no longer operates.
Do not continue to press the On/Off switch after an auto-
matic shut-off of the product. The battery could become
damaged.

Observe the notes for disposal of the battery.
Operation
The saw chain is automatically lubricated with chain oil dur-
ing operation via the oil outlet(7).
The chain saw is not supplied filled with oil.
Be sure to fill the chain saw with chain oil before using it.
It is important to use only biodegradable chain lubricants
(according to RAL-UZ48) to avoid damage to the chain saw.
The recommended Bosch biodegradable chain saw oil can
be found in the accessories.
Filling the oil reservoir: (see figureC)
– Set the chain saw on any suitable surface with the oil filler
cap(19) facing upward.
– Clean the area around the oil filler cap(19) with a cloth
and unscrew the cap.
– Add Bosch biodegradable chain saw oil until the oil level
can be viewed through the oil tank opening (25). You can
check the oil level through the viewing window(25) dur-
ing operation. When the minimum level is reached, top up
with new oil.
Switching On and Off (see figureE1)
uPull the hand guard/activation lever for the kickback
brake (5) from position ➋ to position ➊ towards the
front handle (4). If the hand guard/activation lever for
the kickback brake(5) has not been moved, then the
kickback brake has not been deactivated before use
and the chain saw will not start.
uAlways push the hand guard/activation lever for the
kickback brake forward to the deactivated position
after each use.
– Remove the chain guard (18).
– Hold the chain saw as shown in figureE2.
– Pull the activation lever for the kickback brake(5) back-
wards to the front handle.
– To start the machine, first push the lock-off button for
the On/Off switch (20) and then press the On/Off switch
(2) and keep it pressed. When the machine is running,
the lock-off button can be released again.
– To switch off the power tool, release the On/Off switch
(2).
– The kickback brake is a safety mechanism activated by
the wrist through the front hand guard(5) when kickback
occurs. The chain stops immediately. This reduces the
risk of kickback injury. Try to avoid kickback.
– Periodically push the activation lever for the kickback
brake(5) forward during operation to test the function of
the kickback brake. Stop operation immediately if the
chain saw does not stop immediately.
Note: Do not stop the chain saw after sawing by actuating
the kickback brake(5).
Checking the Lubrication (see figureE3)
– Tilt the chain saw so that the chain bar is 20cm away
from a sheet of paper lying on the ground.
– Switch on the chain saw and let it run for approx.
1minute until oil splashes can be seen on the sheet of pa-
per to confirm that oil is being pulled through the auto-
matic lubrication system.
Note: Operating the chain saw without chain oil or when the
oil level is below the minimum mark will result in damage to
the chain saw.
Note: Oil becomes denser at lower temperatures, which de-
creases the flow rate of oil.
Note: Saw chain life and cutting capacity depend on op-
timum lubrication.

Maintenance and Service
Maintenance and Cleaning
uBefore any work on the garden product itself (e.g.
maintenance, tool change, etc.) as well as during
transport and storage, remove the battery from the
garden product. There is danger of injury when uninten-
tionally actuating the On/Off switch.
– Always fit the chain guard(18) on the chain bar(12)
when the chain saw is not being used to prevent injury.
– For safe and proper working, always keep the power tool
and its ventilation slots clean.
– Do not use water, solvents or polishes.
– Clean the chain and chain bar before storing the product
for an extended period of time to prevent the parts from
seizing.
– Remove the SDS cover(17), chain bar(12) and saw
chain(13) and clean these parts with a brush to remove
oil, sap and dust residue, especially from the saw blade
groove.
– Use a clean cloth to carefully remove debris from the oil
outlet(7) and drive sprocket(3). Make sure that no
debris enters the oil outlet(7), as this can cause block-
ages and lubrication problems.
– Carry out the required maintenance before use.
– Regularly check the chain saw for obvious defects such as
loose, dislodged or damaged saw chain and chain bar,
loose fixings and worn or damaged components.
– Do not modify this product. Unauthorized modifications
may impair the safety of your product and may result in
increased noise and vibration.
– Always empty the oil reservoir before storage and refill it
before use.
– Store the chain saw in a secure, dry place, out of the
reach of children.
– Do not place other objects on the chain saw.
Replacing and Sharpening the Saw Chain
– The saw chain can become blunt through prolonged use
or when coming into contact with objects other than
wood.
– A sharp saw chain is required for optimum performance
and safety.
– Never sharpen the saw chain yourself unless you have ex-
perience with it.
– Replace the saw chain with the Bosch saw chain access-
ory or have the saw chain professionally resharpened.
Replacing the Chain Bar
uOnly replace the chain bar if you fully understand the
product and the instructions, otherwise please con-
tact the Bosch Service Centre.
– If the chain bar is worn, you can mount it upside down to
extend its life, or you can replace it.
– Use a hex key to loosen the screw between the chain
bar(12) and the affixed tensioning wheel(14).
– Once you have flipped or replaced the chain bar, reattach
the affixed tensioning wheel(14).
Note: Tighten by hand until you feel a slight resistance, then
perform1/8 turn for proper fastening. Overtightening can
cause the chain bar to pinch and restrict the path of the ro-
tating saw chain.
