– If the saw chain 10 is overtensioned, turn the chain-ten-
sioning ring 13 in anticlockwise direction.
– When the chain 10 is tensioned, clamp the chain bar 11 by
turning the locking knob 14 in clockwise direction. Do not
use a tool for this.
Saw-chain Lubrication (see figures A and B)
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 19.
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
tank/reservoir is full.
– 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
prevent leakage ensure machine is left in a horizontal position
(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
 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Bosch Power Tools
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 3 and then press the On/Off switch 2 and keep
it pressed.
When the machine is running, the lock-off button can be re-
leased again.
3-4 mm
To switch off the machine, release the On/Off switch 2.
Note: Do not stop chain saw after sawing by actuating the
front hand guard 5 (activating the kickback brake).
To save energy, only switch the power tool on when using it.
Kickback Brake (see figure D)
The kickback brake is a safety mechanism activated through
the front hand guard 5 when kickback occurs. Chain stops im-
mediately.
The following function check should be carried out at regular
intervals. Push front hand guard 5 forward (position ) and
start the chain saw. The chain must not start. To deactivate
the kickback brake, release On/Off switch 2 and pull hand
guard 5 backwards (position ).

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 D)
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.
