Warning:
Do not start the chainsaw before mounting and
correctly adjusting the guide bar and saw chain.
Attention:
Saw chain is extremely sharp - wear gloves when
handling saw chain.
8.1 ATTACHING/ADJUSTING GUIDE BAR AND
CHAIN (FIGS.1 - 4):
Put the chainsaw on a stable rest.
– Loosen the T-screw
turning it anti-clockwise.
– Remove the gear cover
.
–
Put the saw chain
on the bar
considering
the running direction of the saw chain. The cutting
teeth on the upper side of the bar must point in
forward direction (see Fig.3.).
–
Put the free end of the saw chain over the chain
driving wheel
.
–
Place the bar such as that the long hole in the bar
is placed exactly on the guiding element in the bar
seat.
–
Take care that the saw chain tensioning bolt
is seated exactly in the small opening in the bar
(Fig 2). It must be visible through the opening. If
necessary, adjust the knurling wheel of the saw
chain tensioning device
in both directions until
the saw chain tensioning bolt is seated in the
opening in the bar.
–
Check whether all chain links are seated exactly in
the bar’s groove and the chain is lead around the
saw chain driving wheel correctly.
–
Put the gear cover
back on and push it in place.
–
Moderately tighten the T-screw
by turning it
clock-wise.
–
Tension the saw chain. To do so turn the knurling
wheel upwards (+ direction of arrow). The saw
chain should be tensioned such that it can be lifted
by about 3mm in the middle of the bar (Fig.3). To decrease the saw chain tension turn the
knurling wheel downwards (– direction of arrow).
– Finally, tighten the T-screw
hand tight.
– The tension in the chain has a major effect on the service life of the cutting fittings, and
must therefore be checked regularly. When the chain warms up to operating temperature
it will expand and must be re-tightened. A new saw chain will have to be tightened more
frequently until it has reached its full length.
