N Fit chain around the sprocket (11)
and over the guide bar – the cutting
edges on top of the bar must point to
the bar nose.
N Turn the tensioning screw (7)
clockwise until there is very little
chain sag on the underside of the
bar – and the drive link tangs are
engaged in the bar groove.
N Refit the chain sprocket cover –
the pivot pin on the hand guard must
engage the sleeve – and then screw
the nut onto the stud fingertight.
N Go to chapter on "Tensioning the
Saw Chain"
Retensioning during cutting work:
N Switch off the engine.
N Loosen the nut.
N Hold the bar nose up.
N Use a screwdriver to turn the
tensioning screw (1) clockwise until
the chain fits snugly against the
underside of the bar.
N While still holding the bar nose up,
tighten down the nut firmly.
N Go to "Checking Chain Tension".
A new chain has to be retensioned more
often than one that has been in use for
some time.

see chapter on "Operating
Instructions".
