– Place the chain saw on any suitable flat surface.

– Turn  locking  knob 

15

 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 

12

 and on the drive sprocket 

18

.

– Turn the red chain-tensioning ring 

14

 clockwise ratcheting 

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

14

 is hard to turn, loosen the 

locking knob 

15

 further in anticlockwise direction. The 

locking knob 

15

 may also turn, when adjusting the chain-

tensioning ring 

14

.

– The  saw  chain 

11

 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 

11

 is overtensioned, turn the chain-ten-

sioning ring 

14

 in anticlockwise direction.

Clamping the Chain Bar

– When  the  chain 

11

 is tensioned, clamp the chain bar 

12

 by 

turning the locking knob 

15

 in clockwise direction. Do not 

use a tool for this.

Saw-chain Lubrication 
(see figures A – 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.

– Do not remove filter insert during filling.

– Add chain saw oil (preferably biodegradable) until the 

maximum oil level gauge.

– 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 and 
the strainer. To prevent leakage ensure chain saw 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.

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.

To 

switch off

 the machine, release the On/Off switch 

2

.

Note: 

For safety reasons, the On/Off switch 

2

 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 

5

 (activating the kickback brake).

Run-down Brake/Kickback Brake (see figure D)

The chain saw is equipped with two safety features:

The 

run-down brake

 stops the saw chain after releasing the 

On/Off switch 

2

.

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 the front hand guard 

5

 forward (position 



) 

so that the red dot 

28

 under the mark 

6

 becomes visible, and 

briefly start the chain saw. The saw chain must not start. To 
deactivate the kickback brake again, pull the front hand guard 

5

 back (position 



), so that the red dot 

28

 under the mark 

6

is covered.
