Assembly/Tensioning Chain
Do not connect the chain saw to mains be-
fore it is completely assembled.
Always use gloves when handling the chain.
Chain and chain bar Assembly
A
1. Unpack all parts carefully.
2. Place the chain saw on any suitable flat surface.
3. Slide the chain 9 in the slot around the chain
bar 10. Ensure chain is in correct running direc-
tion by comparing with chain symbol 20.
4. Fit the chain onto the drive sprocket 21 and guide
the chain bar 10, so that the fastening bolt 15 and
the two guide fins 18 fit into the keyway of the
chain bar 10, and that the chain tensioning
peg 16 fits into the respective hole of the chain
bar 10. If necessary, adjust chain tensioning
screw 17 to bring tensioning peg 16 in alignment
with the hole in the chain bar 10.
Check if all parts are seated properly and hold
chain and chain bar in a level position.
5. Fit cover plate 12.
6. Handtighten locking nut 14 on fastening bolt 15.
Tensioning chain
A C
Always check the chain tension before use, after the
first cuts and regularly during use, approx. every
10 minutes. Upon initial operation, new chains can
lengthen considerably.
The chain life of the saw chain mainly depends upon
sufficient lubrication and correct tensioning.
Avoid tensioning the chain if it is hot, as this will
cause the chain to become overtensioned when it
cools down.
1. Place the chain saw on any suitable flat surface.
2. Ensure locking nut 14 is hand tight only.
3. Check if the chain links are correctly located in the
slot around the chain
sprocket 21.
4. Turn chain tensioning screw 17 clockwise using
adjusting tool 13, until the correct chain tension is
reached. The screwing action forces the chain
bar 10 forward via the chain tensioning peg 16.
5. The correct chain tension is reached when the
chain 9 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 chain against the
weight of the machine.
6. If the chain 9 is overtensioned, slightly turn the
tensioning screw 17 anti-clockwise and re-check
chain tension. Re-adjust chain tension as de-
scribed if necessary.
7. Re-tighten locking nut 14 fully with adjustment
tool.

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.
– 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.
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.
Starting and Stopping
Observe the correct mains voltage! The voltage
of the power source must agree with the value given
on the nameplate of the machine. Machines desig-
nated for 230 V can also be operated with 220 V.
Starting
bar 10 and drive
Hold chain saw as described in "Cutting".
Press the lock-off button 3, then fully press the On/
Off switch 2 and hold in this position. The lock-off
button 3 can now be released.
Stopping
Release the On/Off switch 2.
Do not stop chain saw after sawing by activating
the front hand guard (kickback brake).
D
The kickback brake is a safety mechanism acti-
vated through the front hand guard 5, when kickback
occurs. Chain stops immediately.

Lubrication
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 dam-
age to the product.
Important: To allow venting of the oil res-
ervoir,small breather channels are pro-
vided between the oil filler cap, to prevent
leakage ensure machine is left in a hori-
zontal position (oil filler cap 4 uppermost)
when not in use.
