– The saw chain 11 is correctly tensioned when it can be
raised approx. 5–10 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.
– If the saw chain 11 is overtensioned, slightly turn the chain
tensioning knob 15 anti-clockwise and re-check chain ten-
sion. Re-adjust chain tension as described if necessary.
– Tighten the cover 13 with the locking knob 12.
Saw-chain Lubrication (see figure E)
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 31.
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 Bosch biodegradable chain saw oil until oil level reads
"max" on oil level gauge 7.
– Avoid dirt or debris from entering the oil reservoir. Screw
on oil filler cap 4 again and tighten.
– Run chainsaw for 30 seconds to "prime" oil system.
Note: To allow venting of the oil reservoir, small breather
channels are provided between the oil filler cap. To prevent
leakage ensure chain saw is left in a horizontal position (oil fill-
er cap 4 uppermost) when not in use.
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: Oil becomes denser at lower temperatures which de-
creases the flow rate of oil.
Operation
Initial Operation
Inserting the battery
Slide the charged battery 17 from behind into the foot of the
power tool. Press the battery fully into the foot until the bat-
tery is securely locked.
Note: The power tool will not operate unless both locking lev-
els 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.
Bosch Power Tools
When the machine is running, the lock-off button can be re-
leased 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 during the entire operation.
Note: Do not stop chain saw after sawing by actuating the
front hand guard 6 (activating the kickback brake).
To save energy, only switch the power tool on when using it.
Kickback brake (see figure F)
The kickback brake is a safety mechanism activated through
the front hand guard 6 when kickback occurs. Chain stop re-
sponse time is 0,15 seconds.
The following function check should be carried out at regular
intervals. Push front hand guard 6 forward (position ) and
start the chain saw. The chain must not start. To deactivate
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 at-
tempted 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, 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-
itial operation, 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. Suitable protective clothing reduces the danger of inju-
ry 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 be-
comes jammed.
When kickback occurs, the chainsaw reacts unpredictable
and can cause heavy injuries to the operator or bystanders.
