– Fit the chain links around the drive sprocket 

18

 and mount 

the chain bar 

11

 in such a manner that the guide fins 

20

 in 

front and behind the fastening bolt 

21

 engage into the key-

way of the chain bar 

11

.

– Check if all parts are seated properly and hold the chain 

bar and the chain in this position.

– Fit  the  cover 

15

 exactly and take care that the chain catch 

bolt 

23

 engages into the groove of the cover plate 

15

.

– Lightly tighten the cover 

15

 with the locking knob 

14

.

– The chain is not yet tensioned. The saw chain is tensioned 

as described in section “Tensioning the Saw Chain”.

Tensioning the Saw Chain (see figures A and C)

Always check the chain tension before use, after the first cuts 
and regularly during use approx. every 10 minutes. Upon ini-
tial 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 and face too tightly against 
the chain bar when it cools down.

– Place the chain saw on any suitable flat surface.
– Turn  locking  knob 

14

 approx. 1 – 3 turns anticlockwise to 

loosen the chain bar.

– Check if the chain links are correctly located in the slot 

around the chain bar 

11

 and on the drive sprocket 

18

.

– Turn the red chain-tensioning ring 

13

 clockwise ratcheting 

until the correct chain tension is reached. The ratchet 
mechanism prevents the chain tension from loosening. If 
the chain-tensioning ring 

13

 is hard to turn, loosen the 

locking knob 

14

 further in anticlockwise direction. The 

locking knob 

14

 may also turn, when adjusting the chain-

tensioning ring 

13

.

– The  saw  chain 

10

 is correctly tensioned when it can be 

raised approx. 3 – 4 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 

10

 is overtensioned, turn the chain-ten-

sioning ring 

13

 in anticlockwise direction.
