CAUTION:
Before doing any work on the guide bar or chain,
always switch off the engine and pull the plug cap
off the spark plug (see 8-6 "Replacing the spark
plug"). Always wear protective gloves!
CAUTION:
Start the chain saw only after having assembled it
completely and inspected.

7a-1. Mounting the guide bar and saw chain

(Fig. 25)
Use the universal wrench delivered with the chain saw for the
following work.
Put the chain saw on a stable surface and carry out the
following steps for mounting the guide bar and saw chain:
Release the chain brake by pulling the hand guard (1) in
direction of arrow.
Unscrew retaining nuts (2).
Pull off the sprocket guard (3).
(Fig. 26)
Turn chain tensioning screw (4) to the left (counter‑clockwise)
until the pin (5) of the chain tensioner is underneath the
threaded pin (6).
(Fig. 27)
Put on the guide bar (7). Make sure that the pin (5) of the chain
tensioner engages in the hole in the guide bar.
(Fig. 28)

CAUTION:
Do not insert the chain between the chain sprocket and the
disc.
Guide the chain from above about halfway into the groove (10)
on the guide bar.
CAUTION:
Note that the cutting edges along the top of the chain must
point in the direction of the arrow!
(Fig. 29)
Pull the chain (9) around the sprocket nose (11) of the guide
bar in the direction of the arrow.
(Fig. 30)
Replace the sprocket guard (3).
IMPORTANT:
Lift the saw chain over the chain catcher (12).
Tighten the nuts (2) only hand‑tight to begin with.

7a-2. Tightening the saw chain

(Fig. 31)
Turn the chain tensioning screw (4) to the right (clockwise)
until the saw chain catches in the groove on the lower side of
the guide bar (see circle).
Slightly lift the end of the guide bar and turn the chain adjusting
screw (4) to the right (clockwise) until the chain rests against
the bottom side of the guide bar.
While still holding up the tip of the guide bar, tighten the
retaining nuts (2) with the universal wrench.

7a-3. Checking the chain tension

(Fig. 32)
The tension of the chain is correct if the chain rests against the
bottom side of the guide bar and can still be easily turned by
hand.
While doing so the chain brake must be released.
Check the chain tension frequently ‑ new chains tend to get
longer during use!
