4. Install guide bar onto saw body. Assemble center
slot of guide bar onto guide bar bolts.
5. To replace sprocket support, repeat step 3 in
reverse 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 chain tensioning knob (Model 107625-
01, -02, 111174-01) or chain tensioning screw
(Model 107624-01, -02), adjust position of
adjustment block 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
chain tensioning knob or chain tensioning screw
counterclockwise will move adjustment block to
rear of guide bar. Turning chain tensioning knob
or chain tensioning screw clockwise will move
adjustment block to front of guide bar.
10. If needed, readjust guide bar nuts to finger tight only.
11. Adjust saw chain tension. Follow steps under
