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

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:
(Fig. 25)
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)
Lift the chain (9) over the sprocket (8).
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.

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.
6a-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!
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.
6a-4. Retightening the saw chain (Fig. 33)
Loosen the nuts (2) about one turn with the universal
wrench.
Raise the tip of the guide bar a little and turn the chain
tensioning screw (4) to the right (clockwise) until the saw
chain is again up against the bottom edge of the guide bar
(see circle).
While keeping the tip of the guide bar raised, tighten the nuts
(2) again with the universal wrench.

6b. Only for the QuickSet guide bar

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