N Turn the guide bar so that the chain
is positioned as shown in the
pictogram (1) – the arrows show the
chain's direction of rotation.
N Fit the guide bar over the studs (2)
and engage the tensioner slide in
the hole (3) – place the chain over
the sprocket (4) at the same time.
N Turn the tensioning screw (5)
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 sprocket cover and tighten
the nut only moderately by hand –
finally tighten the nut only after
tensioning the saw chain.
N Go to chapter on "Tensioning the
Saw Chain".
Re-tensioning during cutting work:
N Disconnect the plug from the wall
outlet.
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.

often than one that has been in use for
some time.
N Check chain tension frequently –
see chapter on "Operating
Instructions".
N Disconnect the plug from the wall
outlet.
N Wear work gloves to protect your
hands.

hand guard (1) against the front
handle and hold it there – the chain
brake and coasting brake are
disengaged in this position.
N The chain must fit snugly against
the underside of the bar and it must
still be possible to pull the chain
along the bar by hand.
N If necessary, re-tension the chain.
A new chain has to be re-tensioned
more often than one that has been in
