Initial Operation

Inserting the Battery
Insert the charged battery 17 from the rear in-
to the handle of the power tool. Push the bat-
tery completely into the handle until the red
stripe can no longer be seen and the battery
is securely locked.
Note: The power tool will not operate unless
both locking levels are engaged.
Switching On and Off
Hold the chain saw as described in section

"Working with the Chain Saw".

To start the machine, first push the lock-off
button for the On/Off switch 2 and then press
the On/Off switch 3 and keep it pressed.
When the machine is running, the lock-off but-
ton can be released again.
To switch off the machine, release the On/Off
switch 3.
Note: For safety reasons, the On/Off switch 3
cannot be locked; it must remain pressed dur-
ing the entire operation.
Note: Do not stop chain saw after sawing by
actuating the front hand guard 6 (activating
the kickback brake).
Kickback brake (see figure F)
The kickback brake is a safety mechanism ac-
tivated through the front hand guard 6 when
kickback occurs. Chain stop response time is
0.15 seconds.
The following function check should be car-
ried out at regular intervals. Push front hand
guard 6 forward (position
chain saw. The chain must not start. To deac-
tivate the kickback brake, release On/Off
switch 3 and pull hand guard 6 backwards
(position
).
Note: When the kick brake is activated and
the chain saw is attempted to be started a
warning sound ("beep") can be heard. To
start chain saw release On/Off switch 3 and
pull hand guard 6 backwards (position
then press the On/Off switch 3.
Working with the Chain Saw
Before Cutting
Before starting operation and periodically
during cutting, carry 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 min-
utes during operation. Upon initial opera-
tion, new chains can lengthen considera-
bly. The condition of the chain influences
the cutting performance. Only a sharp
chain protects from overload.
– Is the kickback brake deactivated and its
function ensured?
Bosch Power Tools
– Are you wearing the required protective
equipment? Wear safety glasses and hear-
ing protection. Further protective equip-
ment for head, hands, legs and feet is rec-
ommended. Suitable protective clothing
reduces the danger of injury from thrown
about cutting material and accidental
touching of the saw chain.
Kickback (see figure F)
Kickback is the sudden backward/upward
motion of the chain saw, occuring when the
chain (at the tip of the chain bar) comes in
contact with a log or wood, or when the chain
becomes jammed.
When kickback occurs, the chainsaw reacts
unpredictable and can cause heavy injuries to
the operator or bystanders.
Particular attention must be given when saw-
ing sidewards, slanted or during length cuts, as
the gripping teeth 8 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 approved low-kickback
saw chain.
– Apply the metal gripping teeth 8 for leverage.
– Ensure correct chain tension.
General Behaviour (see figures F – I)
Always hold the chain saw firmly with both
hands. Front handle with the left hand and
) and start the
rear handle with the right hand. Fully grip
both handles with thumb and fingers at all
times during operation. Never operate chain
saw using only one hand.
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 be-
fore it makes contact with the wood. Use the
),
gripping teeth 8 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 backwards un-
til the gripping teeth release, and reposition
at lower level to continue sawing. Do not re-
move the chain saw completely out of the cut.
Do not force the saw chain while cutting, let
the chain do the work, using the gripping
teeth 8 to apply minimal leverage pressure.
Never operate the chain saw with arms fully
extended. Do not attempt to saw areas which
are difficult to reach, or on a ladder. Never
saw above shoulder height.
Sawing is optimized when the chain speed re-
mains steady during cutting.
Beware when reaching the end of the cut. The
weight of the chain saw changes unexpected-
ly as it cuts free from the wood. Danger of in-
jury to the legs and feet.
Always remove the chain saw from a wood cut
while the saw chain is running.
