Mounting the guide bar and saw chain
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 direc-
tion 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).
Lift the chain (8) over the sprocket (7).
CAUTION:
Do not insert the chain between the chain sprocket and the
disc.
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!
Put the guide bar (5) on and push it against the sprocket (6).
Only for models with quick tensioner
on sprocket guard
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 protec-
tive gloves!
CAUTION:
Start the chain saw only after having assembled it com-
pletely and inspected.
