chain bar in the centre. This should be done by
using one hand to raise the chain against the
weight of the machine.

Lubrication
A B
Important: The chain saw is not supplied
filled with oil. It is essential to fill with oil
before use. Never operate the chain saw
without chain oil or at an empty oil tank level, as
this will result in extensive damage to the prod-
uct.
Chain life and cutting capacity depend on optimum
lubrication. Therefore, the chain is automatically
oiled during operation via the oil outlet 19.
Filling oil tank:
– Set chain saw on any suitable surface with oil
filler cap 4 facing upward.
– Clean area around the oil filler cap 4 with cloth,
unscrew cap.
– Do not remove filter insert during filling.
– Add Bosch biodegradable chain saw oil until res-
ervoir is full.
– Avoid dirt or debris entering oil tank, refit oil filler
cap 4 and tighten.
Important: To allow venting of the oil res-
ervoir,small breather channels are pro-
vided between the oil filler cap and the
strainer, to prevent leakage ensure machine is
left in a horizontal position (oil filler cap 4 upper-
most) when not in use.

It is important to use only the recommended bi-
odegradable oil to avoid damage to the chain
saw. Never use recycled/old oil. Use of non ap-
proved oil will invalidate the warranty.

Do not stop chain saw after sawing by activating
the front hand guard (kickback brake).
Kickback Brake/
Run Down Brake
The chain saw is equipped with two chain brake sys-
tems for user safety:
The run down brake automatically stops the chain
and motor after the switch lever (On/Off) 2 is re-
leased.
The kickback brake is a safety mechanism acti-
vated through the front hand guard 5, when kickback
occurs. Chain stops immediately.
Perform an operational check from time to time.
Push the front hand guard 5 to the front (position
so that the red dot 28 becomes visible under the
mark 6 and briefly switch on the chain saw. The
chain must not start. In order to release the kickback
brake again, pull back the front hand guard 5 (posi-
tion ) so that the red dot 28 is covered under the
mark 6. (see figure

– Is the chain saw in a fail-safe condition?
– Is the oil reservoir filled? Check oil level

gauge 26 prior to starting and regularly during op-
eration. Refill oil when oil level is low. The oil tank
filling will last approx. 15 minutes, depending on
sawing intensity and stops.
