6c. Only for models with quick tensioner on sprocket guard (TLC)

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 7‑6 "Replacing the spark
plug"). Always wear protective gloves!
CAUTION:
Start the chain saw only after having assembled it
completely and inspected.

6c-1. Mounting the guide bar and saw chain

(Fig. 41)
Place the saw on a stable surface and perform the following
work steps in order to install the guide bar and saw chain:
Release the chain brake by pulling the hand guard (1) in
direction of arrow.
Fold up the sprocket guard quick tensioner (2) (see also the
illustration on tensioning the saw chain).
Push the sprocket guard quick tensioner in forcefully against
the spring tension and slowly turn counter-clockwise, until
you feel it engage. Keep pushing, and turn as far as possible
counter‑clockwise.
Release the sprocket guard quick tensioner again and turn
clockwise to bring it back to its original position. Repeat this
procedure until the sprocket guard (4) is unscrewed.
Remove the sprocket guard (4).
(Fig. 42)
Put the guide bar (5) on and push it against the sprocket (6).
(Fig. 43)
Lift the chain (8) over the sprocket (7).
Guide the chain from above about halfway into the groove (9)
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. 44)
Pull the chain (8) around the sprocket nose (10) of the guide
bar in the direction of the arrow.
(Fig. 45)
Align hole on sprocket guard (4) with the pin (11).
Turn the chain tensioner (3, see 6c‑2 "Tightening the saw
chain") to bring the chain tensioner pin (12) into alignment with
the hole in the guide bar.
Push the sprocket guard (4) onto the pin (11).

6c-2. Tightening the saw chain

(Fig. 46)
Simultaneously push in hard on the sprocket guard quick
tensioner (2) and turn it clockwise to screw the sprocket guard
on, but do not yet tighten it.
Raise the tip of the guide bar slightly and turn the chain
tensioner (3) clockwise until the saw chain is flush against the
bottom of the guide bar (see circle).
Push the sprocket guard quick tensioner (2) in again and
tighten by turning clockwise.
(Fig. 47)
Release the sprocket guard chain tensioner until it turns freely,
then fold it in between protective ribs (15) as shown in the
illustration.

6c-3. Checking the chain tension

(Fig. 48)
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!
When checking the chain tension the engine must be switched
off.
NOTE: It is recommended to use 2‑3 chains alternatively.
In order to guarantee uniform wear of the guide bar the bar
should be turned over whenever replacing the chain.

6c-4. Retensioning the saw chain

(Fig. 49)
All that is necessary to retension the saw chain is to loosen the
quick tensioner (2) slightly as described under "Mounting the
guide bar and saw chain".
Tension the chain as already described.
