•  After use, lay the chainsaw horizontally on some absor-

bing surface. The oil spread on the blade, chain and 
drive may lead to some further dripping of oil. 

3.2. Assembling the blade and chain 

(Fig. 3-4)

CAUTION  ! Risk of injury !  Always  use safety 

gloves when assembling the chain !

For assembling the bar and chain with this chain saw 

no tools are required !

•  Put the chain saw on a stable rest. 
•  Loosen the T-screw (7) turning it clockwise.
•  Remove the gear cover (8).
• Put the chain on the bar considering the running 

direction of the chain. 

The cutting teeth on the upper 

side of the bar must point in forward direction 

(see 

Fig. 4).

•  Put the free end of the chain over the chain driving 

wheel (B). 

•  Place the bar such that the long hole in the bar is 

placed exactly on the guiding element in the bar seat. 

•  Take care that the chain tensioning bolt (A) is seated 

exactly in the small opening in the bar (Fig. 3). It must 
be visible through the opening. If necessary, adjust the 
knurling wheel of the chain tensioning device (16) in 
both directions until the chain tensioning bolt is seated 
in the opening in the bar.

•  Check whether all chain links are seated exactly in the 

bar’s groove and the chain is lead around the chain 
driving wheel correctly.

•  Put the gear cover (8) back on and push it in place.
•  Moderately tighten the T-screw (7) by turning it clock-

wise.

•  Tension the chain. To do so turn the knurling wheel 

upwards (+ direction of arrow). The chain should be 
tensioned such that it can be lifted by about 3mm in 
the middle of the bar (Fig. 4). To decrease the chain 
tension turn the knurling wheel down-wards (- direction 
of arrow).

•  Finally, tighten the T-screw (7) well by hand.

The tension in the chain has a major effect on the service 
life of the cutting fi ttings, and must therefore be checked 
regularly. When the chain warms up to operating tem-
perature it will expand and must be retightened. A new 
saw chain will have to be tightened more frequently until 
it has reached its full length.

CAUTION:  During the running-in period, the 

chain  must be more frequently tightened. The 

chain  must be immediately retightened if it 

shakes or leaves the grove !

To tension the chain slightly loosen the T-screw (7). Then 
turn the knurling wheel upwards (+ direction of arrow). 
Tension the chain such that it can be lifted by about 3mm 
in the middle of the bar, as shown in Fig. 4.

3.3. Connecting the chainsaw 

(Fig. 5) 

We recommend to operate the chain saw in connec-

tion  with a residual current operated device with a 

maximum breaking current of 30mA.

This device is designed to be operated on a mains supp-
ly with a system impedance Z max at the point of con-
nection (house service connection) of max. 0.4 Ohm. The 

user must ensure that the device is only operated on an 
electricity supply  system meeting these require-ments.  
If required,  system  impedance  data may be obtained 
from the local public utility.

Use only extension cords that are approved for 

outdoor  use and are not lighter than rubber-

sheathed cables of type H07 RN-F according to 

DIN/VDE 0282 with a diameter of at least 1.5 sq. 

mm.  They cords must be splash-proof. If the 

connection cable of this device should be dam-

aged it must be replaced by a workshop named 

by the manufacturer only as this work requires 

the use of special tools. Mobile devices for out-

door  use should be connected over a residual 

current operated device.

This chainsaw is fi tted with a strain-relief device to pro-
vide extra safety for the connection. First connect the 
device plug with the connection line. Form a narrow loop 
with the connecting cable, press on the button and swivel 
the cable holder (18) out into position A. Now insert the 
loop of cable from below into the mains lead cleat. Once 
you have released the cable hook button, it will auto-
matically return to starting position B and the cable will 
be held in place. Press the cable holder button again to 
loosen the cable and pull out the cable.

3.4.  Switching on

 (Fig. 6) 

• Press with your thumbs the stopping button (15) on 

the left side of the rear handle and then the operating 
switch (9).

• The stopping button (15) is used for unlocking the 

switch-on mechanism and does not need to be pressed 
again after the device is switched on.

•  To switch off the device, release switch (9).

Attention:  The sawing  chain will start running 

at high  speed  immediately.   When putting the 

saw down, make sure that the chain never gets 

in touch with stones or metal objects.

4. Safety devices on your chain brake

4.1. Chain brake 

(Fig. 7) 

This chain saw is equipped with a mechanical brake for 
the chain. In the case of uncontrolled movements, when 
the tip of the sax blade gets in contact with wood  or a 
solid object, the drive of the chain is immediately stopped 
by activation of the hand guard (4), the motor will not 
be stopped. This brake function is initiated by the back 
of your hand on the front handle (2) pushing the hand 
guard. The proper function of the saw chain brake shall 
be checked before each use of the saw.

CAUTION: No buttons should be pressed when 

the  chain brake is released (hand protection 

pulled  back in the direction of the handle and 

locked).

Always  ensure before starting the chainsaw that 

the  hand protection (4) is locked in the operating 

position. To do this, pull back the hand protection  in 

the direction of the handle.
4.2. Rundown brake

In accordance with the latest regulations, this chain saw
