4. Install guide bar onto saw body. Assemble cen-
ter slot of guide bar onto guide bar bolts.
5. To replace sprocket support, repeat step 3 in re-
verse order. Firmly tighten drive sprocket screw
with #2 Phillips screwdriver (if applicable).
6. Place chain around drive sprocket, along top
groove of guide bar, and around guide bar nose.
Note:
Make sure cutting edges of chain are fac-
ing in right direction. Position chain so cutting
edges on top of guide bar face guide bar nose (see
Figure 4, and indicator on side cover of saw).
CAUTION: Do not place chain on
saw backwards. If chain is backwards,
saw will vibrate badly and will not cut.
7. Insert tab of sprocket cover into slot on side cover
and rotate sprocket cover onto guide bar bolts until
sprocket cover rests against guide bar.
8. Place guide bar nuts, removed in step 2, over
guide bar bolts.
IMPORTANT:
Tighten guide bar nuts finger
tight only.
9. Turning thumbscrew (Model 107625-01, -02,
111174-01) or tensioner screw (Model 107624-
01, -02), adjust position of nib until it is aligned
and inserted into the round adjusting hole on guide
bar (see Figure 4 and Figures 5 and 6, page 8).
Turning thumbscrew or screw counterclockwise
will move tensioner bar to rear of guide bar. Turn-
ing thumbscrew or screw clockwise will move
tensioner bar to front of guide bar.
10. If needed, readjust guide bar nuts to finger tight only.
11. Adjust saw chain tension. Follow steps under
