English 15 Assembling the Chain Saw
► Turn the tensioning gear clockwise until it stops.
► Point the guide bar tip away from the chain sprocket (2),
with the teeth of the tensioning gear (4) facing away from
the motor.
► Place the chain around the chain sprocket.
► Slide the guide bar over the collar screw (3). The head of
the collar screw must protrude into the oblong hole.
► Disengage the chain brake, @ 16.2.
► Direct the drive links into the groove of the guide bar
(arrow) while turning the tensioning gear (4)
counterclockwise until it stops.
The guide bar and chain must be firmly and securely
mounted on the saw.
► Fit the sprocket cover on the saw so that it is flush with the
housing.
► When fitting the chain sprocket cover, the teeth of the
adjusting wheel and the tensioning gear must mesh.
► If necessary, turn the adjusting wheel slightly until the
chain sprocket cover sits flush against the housing.
► Turn the wingnut clockwise until the chain sprocket cover
is firmly attached to the saw.
► Close the handle of the wingnut.
15.2.2 Removing the Guide Bar and Chain
► Raise the handle of the wingnut to open and then turn the
wingnut counterclockwise until the chain sprocket cover
can be removed.
► Remove the chain sprocket cover.
► Turn the tensioning gear counterclockwise until it stops
and the chain is loose.
► Remove the guide bar, including the tensioning gear and
chain.
NOTICE
The top and bottom of the guide bar are symmetrical, and
the bar may be mounted with the printing facing up or down.
Flipping the guide bar each time the chain is sharpened or
changed will help reduce uneven wear and improve its
service life.
15.3 Tensioning the Saw Chain
WARNING
To reduce the risk of severe personal injury from chain
derailment, check chain tension frequently, @ 6.5. At
operating temperatures, the chain stretches and sags. New
chain tends to stretch more than used chain. Tension the
chain so that the drive links cannot come out of the groove
on the underside of the guide bar.
To properly tension the chain:
► Switch off the chain saw, @ 18.2.
► Engage the chain brake, @ 16.1.
► Remove the battery, @ 17.2.
► Raise the handle of the wingnut (1).
► Turn the wingnut counterclockwise twice or until the chain
is loose.
