ASSEMBLING AND PREPARING FOR USE
1. Assembling the guide bar and saw chain (Fig. 2)
Warning! Risk of injury. Before performing any maintenance operation unplug the power cord
from the wall socket. When mounting the chain wear protective gloves. Use only
manufacturer‐recommended guide bar and saw chain.
Electric chain saw is equipped with either a standard nut clamping bar (7) and the front chain tensioning
screw (17) or quick‐locking nut (7A) and the side chain tensioning (17A). Mounting rail and chain tensioning
therefore these details differ.

Place the chain saw on a stable, level surface.

Make sure the chain brake is turned off ‐ pull the brake lever (4) towards the front handle (2) (Fig. 2‐A).

Release the fastening nut (7) or knob (7A) in counter‐clockwise direction and remove side cover (8).

Make sure that the chain tensioner pin (19) is in the maximum position back (Fig. 2‐B) ‐ if not turning
the tensioning mechanism (17 or 17A) to move it backward.

Fit the saw chain onto the bar and observe the direction of the chain. The cutting teeth must be
pointing forward on the top of the bar (Fig. 2‐C).

Fit the unattached end of the saw chain over the sprocket (16) and the bar (5) with the elongated hole
over the guide bar and chain tensioning pin (19). Observe that the chain tensioning pin is sitting exactly
in the small opening in the bar (Fig. 2‐D). It must be visible through the opening.

Now push the bar together with the chain forwards. Observe that all chain links are positioned exactly
in the bar groove and that the saw chain is fitted precisely around the guide bar.

Replace the side cover (8) by inserting the tab into the opening in the housing plate (Fig. 2‐E) and press
it to the bar, making sure the chain catcher is properly seated in its hole.

Screw the fastening nut (7 or 7A). The securing nut should initially only be tightened by hand.

Tighten the chain. To do this, turn the chain tensioning screw (17 or 17A, Fig. 2‐G) in a clockwise
direction. The chain should be tensioned so that it can still be raised approx. 3 mm in the middle of the
bar (Fig. 2‐F), and it can be hand moved freely along the bar.

Finally, tighten the fastening nut. In case of nut (7) use a socket spanner (21); in case of knob (7A) use
hand (Fig 2‐H). Keep your saw supported on the tip of the bar while tightening.
The tension in the chain has a major effect on the service life of the cutting fittings, and must therefore be
checked regularly. When the chain warms up to operating tempe‐rature 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.
If the chain vibrates or fall out of the bar groove, you must tighten it instantly!
For the chain tensioning slightly loosen the fixing nut (7 and 7A). Then tighten the chain as described above.
