Assembling saw chain and guide bar
CAUTION: Make sure that the saw chain, guide bar and sprocket match each
other in gauge and pitch.
Assemble the saw chain and guide bar as the following steps.
1. Loosen the nut (A) and remove the bar holder (B).
2. Turn the tension screw (C) counterclockwise until the tensioning nut (D)
touches the left end.
NOTICE:
• Do not turn the tension screw counterclockwise too much, otherwise the
tension screw and the tensioning nut comes off from the housing.
3. Fit the saw chain (E) into the groove of guide bar (F). Start the procedure
from the bar nose.
4. Align the position bolt (G) with the notch of the guide bar (H), and then fit
the saw chain (E) onto the sprocket (I). Make sure that the saw chain is kept
fitting along the guide bar during the procedure.
5. Install the guide bar (F) so that the tensioning nut (D) fits into the hole (J) on
the guide bar. Holes (K) are not used.
6. Place the saw chain onto the groove of the guide bar properly. If the saw
chain is not placed into the groove of the guide bar properly at this point,
adjust and fit it appropriately.
7. Fit the bar holder (B) and tighten the nut (A) securely. Then loose the nut a
half turn as a provision of the chain tension adjustment.
8. Adjust the chain tension. Refer to the section "Adjusting the chain tension."
CAUTION:
• Keep the applicable chain tension. Loose tension can cause the saw chain
derail.
To remove the saw chain and guide bar, turn the tension screw (C)
counterclockwise first.
Pull the saw chain outward to let the saw chain comes out from the groove of
the guide bar, then remove them from the housing.
