Lift the chain (11) over the clutch drum and onto the sprocket
(12). Using your right hand, guide the chain into the top guide
groove on the guide bar. Note that the cutting edges along the
top of the chain must point in the direction of the arrow!
Lead the chain (11) around the sprocket nose (13) of the guide
bar.
NOTE:
The chain should be easy to pull in the direction of the arrow.
The clutch drum (E/12) should turn with the chain (the sprocket
engages the chain).
First push the sprocket guard (3) into the mounting (4) and then
over the mounting bolt (14).
NOTE:
If the chain brake on the dismounted chain guard is inadver-
tently actuated, it will not be possible to push the sprocket
guard all the way over the mounting bolt. You will first have to
release the chain brake (Fig. B).
Tighten the mounting nut (2) hand-tight.
Tightening the saw chain
Turn the chain tightener (C/6) to the right (clockwise)
until the chain engages the guide groove of the bottom side of
the bar (see circle).
Slightly lift the end of the guide bar and turn the chain adjusting
screw (C/6) to the right (clockwise) until the chain rests against
the bottom side of the guide bar.
While still holding up the guide bar, tighten the retaining nut (2)
with the universal wrench.
