 Do not expose power tools to rain or wet conditions.
Waterenteringapowertoolwillincreasetheriskofelectric
shock.
 Do not abuse the cord. Neveruse the cord for carrying,
pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges and moving parts.Damaged
or entangled cords increase the risk of electric shock.
 When operating a power tool outdoors, use an exten-
sioncord suitablefor outdooruse.Use ofa cord suitable
for outdoor use reduces the risk of electric shock.
 If operating a power tool in a damp location is unavoid-
able, use a residual current device (RCD) protected
supply. Use of an RCD reduces the risk of electric shock.
Personal safety
 Stay alert, watch what you are doing and use common
sensewhenoperatinga power tool.Do notuse apower
toolwhileyouaretiredorundertheinfluenceofdrugs,
alcohol or medication. A moment of inattention while op-
erating power tools may result in serious personal injury.
 Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal inju-
ries.
 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 en-
ergising power tools that have the switch on invites acci-
dents.
 Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a ro-
tating 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 jewel-
lery. 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 ex-
traction and collection facilities, ensure these are con-
nected and properly used. Use of dust collection can re-
duce dust-related hazards.
Power tool use and care
 Donotforcethepowertool.Usethecorrectpower 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 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 bind-
ing of moving parts, breakage of parts and any other
conditionthat may affectthe power tool’s operation. If
damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power
tools.
 Keepcuttingtoolssharpandclean.Properly maintained
cuttingtoolswithsharpcuttingedgesarelesslikelytobind
and are easier to control.
 Use the power tool, accessories and tool bits etc. in ac-
cordance 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.
Service
 Haveyourpowertoolservicedbyaqualifiedrepairper-
son using only identical replacement parts. This will en-

Chain Saw Safety Warnings
 Keep all parts of the body away from the saw chain
whenthemotorisoperating.Beforeyoustartthechain
saw, make sure the saw chain is not contacting any-
thing.Amomentofinattentionwhileoperatingchainsaws
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 on-
ly,becausethesawchainmaycontacthiddenwiringor
its own cord. 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.
 Donotoperateachainsawinatree.Operationofachain

leased 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 re-
duce the likelihood of accidental contact with the moving
saw chain.
 Follow instructions for lubricating, chain tensioning
andchangingaccessories.Improperly tensionedorlubri-
cated 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. Don’t use chain saw for purposes not in-
tended. For example: do not use chain saw for cutting
plastic,masonryornon-woodbuildingmaterials.Useof
the chain saw for operations different than intended could
result in a hazardous situation.
 Causes and operator prevention of kickback:

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 oper-
ating procedures or conditions and can be avoided by tak-
ing proper precautions as given below:
 Maintain a firm grip, with thumbs and fingers encir-
clingthechainsawhandles,withbothhandsonthesaw

ter 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 mainte-
nance instructions for the saw chain. Decreasing the
depth gauge height can lead to increased kickback.
Additional safety warnings
 It is recommended that the first time user should have
practicalinstructionintheuseofthechainsawandthepro-
tective equipment from an experienced operator. The ini-
tial practice should be cutting logs on a saw horse or cra-
dle.

tices older than 16 years and under supervision, may
not operate the chain saw. The same applies for per-
sons whodo not ordo not sufficientlyknowhow tohan-
dle the chain saw. The operating instructions should al-
ways be ready to hand. Persons unfit or tired must not
operate the chain saw.
 When working with the machine, always hold it firmly
with both hands and provide for a secure stance. The
power tool is guided more secure with both hands.
 Always 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.
 Always wait until the machine has come to a complete
stop before placing it down. The tool insert can jam and
lead to loss of control over the power tool.

Saw-chain Lubrication (see figures A, B and D)
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 23.
Filling the oil reservoir:
– Set chain saw on any suitable surface with the oil filler cap
4 facing upward.
– Clean area around the oil filler cap 4 with a cloth and un-
screw the cap.
– Add chain saw oil (preferably biodegradable) until the
maximum oil level gauge.
– Avoid dirt or debris from entering the oil reservoir. Screw
on oil filler cap 4 again and tighten.
Note: Important: To allow venting of the oil reservoir, small
breather channels are provided between the oil filler cap, to
preventleakageensuremachineisleftinahorizontalposition
(oil filler cap 4 uppermost) when not in use.
Note: It is important to use only chain saw oil (preferably bio-
degradable) to avoid damage to the chain saw. Never use re-
cycled/ old oil as doing so will invalidate the warranty.
Operation
Initial Operation

Working with the Chain Saw
Before Cutting
Before starting operation and periodically during cutting, car-
ry out the following checks:
– Is the chain saw in a fail-safe condition?
– Is the oil reservoir filled? Check oil level gauge prior to
starting and regularly during operation. Refill oil when oil
level has reached the bottom edge of the viewing glass.
The oil tank filling will last approx. 15 minutes, depending
on sawing intensity and stops.
– Is the saw chain properly tensioned and sharp? Check
chain tension every 10 minutes during operation. Upon in-
itialoperation, new chains can lengthen considerably. The
condition of the chain influences the cutting performance.
Only a sharp chain protects from overload.
– Is the kickback brake deactivated and its function en-
sured?
– Are you wearing the required protective equipment? Wear
safety glasses and hearing protection. Further protective
equipment for head, hands, legs and feet is recommend-
ed.Suitableprotectiveclothing reducesthedanger ofinju-
ry from thrown about cutting material and accidental
touching of the saw chain.
Kickback (see figure F)
Kickbackisthesuddenbackward/upwardmotionofthechain
saw, occuring when the chain (at the tip of the chain bar)
comes in contact with a log or wood, or when the chain be-
comes jammed.
When kickback occurs, the chainsaw reacts unpredictable
and can cause heavy injuries to the operator or bystanders.
Particular attention must be given when sawing sidewards,
slanted or during length cuts, as the gripping teeth11 usually
can not be applied.
To avoid kickback:
– Saw with the chain bar at a flat angle.
– Never work with a loose, widely stretched or heavily worn
out saw chain.
– Sharpen the saw chain as specified.
– Never saw above shoulder height.
– Never work with the tip of the chain.
– Always hold a chain saw firmly with both hands.
– Always use a Bosch low-kickback saw chain.
– Apply the metal gripping teeth 11 for leverage.
– Ensure correct chain tension.
General Behaviour (see figures F – I)
Always hold the chain saw firmly with both hands. Front han-
dle with the left hand and rear handle with the right hand. Ful-
ly grip both handles withthumb and fingersat all times during
operation. Never operate chain saw using only one hand. En-
sure power cord is located to the rear, and keep it out of the
range of the saw chain and cutting material; position yourself
in such a manner that the mains cable can not get caught in
branches and twigs.
Use the chain saw only with secure footing. Hold the chain
saw at the right-hand side of your body.
The chain must be running at full speed before it makes con-
tact with the wood. Use the gripping teeth 11 to support the
chain saw on the wood. Use the gripping teeth as a leverage
point while cutting.
Reset the gripping teeth at a lower point when sawing thicker
logs or tree trunks. For this, pull the chain saw slightly back-
wardsuntilthegrippingteethrelease,andrepositionatlower
level to continue sawing. Do not remove the chain saw com-
pletely out of the cut.
Do not force the saw chain while cutting, let the chain do the
work, using the gripping teeth 11 to apply minimal leverage
pressure.
Never operate the chain saw witharmsfully extended. Do not
attempt to saw areas which are difficult to reach, or on a lad-
der. Never saw above shoulder height.
Sawing is optimized when the chain speed remains steady
during cutting.
Beware when reaching the end of the cut. The weight of the
chain saw changes unexpectedly as it cuts free from the
wood. Danger of injury to the legs and feet.
Always remove the chain saw from a wood cut while the saw
chain is running.
Cutting Logs (see figures G and I)
When cutting logs, observe the following safety instructions:
Support logs so that the face sides at the cut do not close in
against each other, which would result in the chain being
jammed.
Position and set short logs safely before sawing.
Sawonlywoodorwoodenobjects.Whensawing,alwaystake
care to avoid hitting stones, nails, etc., as these could be
thrownup,couldcausedamagetothechain,orcouldresultin
serious injury to the operator or bystanders.
Keep a running chain saw clear of wire fencing or the ground.
Useofthesawtothinoutbranchesorbushesisnotapproved.
Length cuts must be carried out with particular care, as lever-
age with the gripping teeth11 is notpossible. Saw ata flatan-
gle to avoid kickback.
When working on a slope, operate above or to the side of the
trunk or laying tree.
Be careful not to trip over tree stumps, branches, roots, etc.
Cutting Wood under Tension (see figure J)
 Be extremely careful when sawing wood, branches or
trees under tension. Leave saw jobs like these to
trained professionals. There is a high risk of accidents.
When sawing logs supported on both ends, start the cut from
above (Y) about one third of the diameter into the log and
thenfinishthecutatthesamespotfrombelow(Z),inorderto
avoid splitting of the log or jammingof the saw. Avoid contact
of the saw chain with the ground.

F 016 L81 139 | (16.10.14) Bosch Power Tools
When sawing logs supported on only one end, start the cut
from below (Y) about one third of the diameter into the log
and then finish the cut at the same spot from above (Z), in or-
der to avoid splitting of the log or jamming of the saw.
Felling Trees (see figure K)
 Always wear hard hat to protect head against falling
branches.
 The chain saw may only be used to fell trees smaller in
diameter than the length of the chain bar.
 Securetheworkarea.Ensurenopersonsoranimalsare
in the vicinity of the falling tree ().
 Never attempt to free a jammed chain saw with the mo-
tor running. Use wooden wedges to free a jammed
chain saw.
When cutting and felling operations are being performed by
two or more persons at the same time, the felling operations
shouldbeseparatedfromthecuttingoperationsbyadistance
of at least twice the height of the tree being felled. Trees
should not be felled in a manner that would endanger any per-
son,strikeanyutilitylineorcauseanypropertydamage.Ifthe
treedoesmakecontactwithautilityline,thecompanyshould
be notified immediately.
The chain saw operator should keep on the uphill side of the
terrain as the tree is likely to roll or slide downhill after it is
felled.
An escape path () should be planned and cleared as neces-
sary before cuts are started. The escape path should extend
back and diagonally to the rear of the expected line of fall.
Before felling is started, consider the natural lean of the tree,
thelocationoflargerbranchesandthewinddirectiontojudge
which way the tree will fall.
Remove dirt, stones, loose bark, nails, staples, and wire from
the tree.
Notching undercut: Make the notch (X – W) 1/3 the diame-
ter of the tree, perpendicular to the direction of fall. Make the
lower horizontal notching cut first. This will help to avoid
pinching either the saw chain or the guide bar when the sec-
ond notch is being made.
Felling back-cut: Make the felling back-cut (Y) at least
50 mm higher than the horizontal notching cut. Carry out the
felling back-cut parallel to the horizontal notching cut. Make
the felling back-cut so that enough wood is left to act as a
hinge. The hinge-wood keeps the tree from twisting and fall-
ing in the wrong direction. Do not cut through the hinge.
As the felling gets close to the hinge, the tree should begin to
fall. If there is any chance that the tree may not fall in the de-
sired direction or may rockback and bind the saw chain, stop
cutting before the felling back-cut is complete and use wedg-
es of wood, plastic or aluminium to open the cut and drop the
tree along the desired line of fall.
When the tree begins to fall, remove the chain saw from the
cut, stop the motor, put the chain saw down, then use the re-
treat path planned. Be alert for overhead limbs falling and
watch your footing.
Drive a wedge (Z) into the horizontal cut to make the tree fall.
When the tree begins to fall, leave the danger area via the re-
treat path planned. Be alert for overhead limbs falling and
watch your footing.
Limbing a Tree (see figure L)
Limbing is removing the branches from a fallen tree. When
limbing, leave larger lower limbs to support the log off the
ground.Removethesmalllimbsinonecutasillustratedinthe
figure.Branchesundertensionshouldbecutfromthebottom
up to avoid binding the chain saw.
Bucking a Log (see figures M–P)
Bucking is cutting a log into lengths. It is important to make
sure your footing is firm and your weight is evenly distributed
onbothfeet.Whenpossible,thelogshouldberaisedandsup-
ported by the use of limbs, logs or chocks. Follow the simple
directions for easy cutting.
Whenthelogissupportedalongitsentirelength,itiscutfrom
the top (overbuck).
When the log is supported on one end, cut 1/3 the diameter
from the underside (underbuck). Then make the finished cut
by overbucking to meet the first cut.
Whenthelogissupportedonbothends,cut1/3thediameter
from the top overbuck. Then make the finished cut by under-
bucking the lower 2/3 to meet the first cut.
When bucking on a slope, always stand on the uphill side of
the log. When “cutting through”, release the cutting pressure
near the end of the cut without relaxing your grip on the chain
saw handles in order to maintain complete control. Don’t let
the chain contact the ground. After completing the cut, wait
for the saw chain to stop before you move the chain saw. Al-
ways stop the chain saw motor before moving from tree to
tree.

Troubleshooting
The following chart lists problem symptoms, possible causes and corrective action, if your machine does not operate properly.
If these do not identify and correct the problem, contact your service agent.
 Warning: Switch off and remove plug from mains before investigating fault.
Maintenance and Cleaning
 Before any work on the machine itself, pull the mains
plug.
If the replacement of the supply cord is necessary, this has to
be done by Bosch or an authorized Bosch service agent in or-
der to avoid a safety hazard.
Note:Toensurelongandreliableservice,carryoutthefollow-
ing maintenance regularly.
Regulary 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.
Check that covers and guards are undamaged and correctly
fitted. Carry out necessary maintenance or repairs before us-
ing.
Note: Before returning the chain saw, ensure all oil in the oil
reservoir has been emptied.
Replacing/ChangingtheSawChainandChainBar
Check the saw chain and chain bar according to section “Ten-
sioning the Saw Chain”.
The circular groove of the chain bar will wear particularly on
the lower edge with time. When replacing the saw chain, turn
the chain bar by 180° to allow even wear, thus extending
chain bar life.
Check the drive sprocket 20. If it is worn out or damaged due
to strain, have it exchanged by an authorized Bosch after-
sales service.
Sharpening the Saw Chain
Have your chain sharpened professionally at your authorised
Bosch after-sales service or sharpen it yourself with a sharp-
ening kit suitable for the chain recommended for your chain-
saw. Observe the sharpening instructions provided with the
sharpening kit.
Checking the Automatic Oiler
Proper functioning of the automatic saw chain oiler can be
checked by running the chain saw and pointing the tip of the
chain bar towards a piece of cardboard or paper on the

safety clearance of 20 cm. If an increasing oil pattern devel-
opes, the automatic oiler is operating fine. If there is no oil
pattern despite a full oil reservoir, see section “Troubleshoot-
ing” or contact your authorized Bosch after-sales service.
After Use/Storage
Clean the moulded plastic housing of the chain saw using a
soft brush and clean cloth. Do not use water, solvents or pol-
ishes. Remove all debris, especially from the motor cooling
vents.
After 1 – 3 hours of use, remove the cover 13, the chain bar
10 and the saw chain 9, and clean them using a brush.
Clean the area under the cover 13, the drive sprocket 20 and
the chain bar assembly from adherant debris using a brush.
Clean the oil outlet 23 with a clean cloth.
If the chain saw is to be stored for a longer period of time,
clean the saw chain 9 and the chain bar 10.
