REPLACING SAW CHAIN
IMPORTANT: Do not clamp chainsaw in vise to replace saw chain or guide bar.
Replace chain when cutters are too worn to re-sharpen or when the chain breaks. Only
use replacement chain noted in this manual. Always include a new drive sprocket when
replacing the chain. This will maintain proper driving of chain. (Note: For proper chain
and drive sprocket, see Parts List.)
Refer to Figure 19 while completing the following steps.
1. Loosen and remove guide bar screw.
2. Remove sprocket cover.
3. Remove saw chain.
4. Place new chain around drive sprocket, along top groove of guide bar, and around
guide bar nose.
Note: Make sure cutting edges of chain are facing in right direction.
Position chain so cutting edges on top of guide bar face guide bar nose (
see Fig 20
and
indicator on side cover of saw
).
5. Before placing sprocket cover into positioning groove, verify that the adjusting nib is
in the adjusting hole on the guide bar.
6. Place sprocket cover into positioning groove.
7. Locking the sprocket cover with guide bar screw.
(IMPORTANT: Finger tighten only.)
8. Adjust the chain tension.
9. Securely tighten guide bar screw with Hexagon wrench.
CAUTION: Do not place chain on saw backwards. If chain is backwards, saw will
vibrate badly and will not cut.
