4.2 ASSEMBLY OF THE GUIDE
BAR AND TOOTHED CHAIN
Always wear heavy-duty gloves when
handling the bar and chain. Mount the
bar and chain very carefully so as not to
impair the safety and efficiency of the
machine. If in doubt, contact your dealer.
Perform all operations
with the engine off.
Before assembling the bar, check that
the chain brake is not engaged (par. 5.7).
1. Loosen all the nuts (Fig. 3.A) and remove
the clutch cover (Fig. 3.B) to get to the drive
sprocket and the point where the bar is fitted.
2. Remove the plastic spacer (Fig. 3.C); this
spacer must be used exclusively when
transporting the machine in its packaging
and must not be used at any other time.
3. Mount the bar (Fig. 4.A) by inserting the stud
bolts (Fig. 4.B) in the groove (Fig. 4.C) and
push it towards the back of the machine body.
4. Mount the chain (Fig. 5.A) around the
drive sprocket (Fig. 5.B) and along the
bar guide (Fig. 5.C), making sure it is
fitted in the right direction (Fig. 5.D).
If the tip of the bar is equipped with a nose
sprocket, make sure the drive links are
correctly inserted in the sprocket rims (Fig. 6).
5. Check that chain tension adjuster pin
(Fig. 7.A) is fitted properly in the hole on
the bar; if it isn't, turn the chain tension
adjuster screw using a screwdriver (Fig.
7.B), until the pin is completely inserted.
6. Replace the guard without
fully tightening the nuts.
7. Turn the chain tension adjuster screw (Fig.
8.A) to achieve the desired tension.
8. Raise the bar and tighten the guard nuts
securely using the wrench (Fig. 9).
