4.Holding the chain over the guide bar nose, position the back end of the guide bar against the drive sprocket at a 45° angle to the power head. Pass the free end of the chain around the drive sprocket, swing the guide bar into place over the mounting bolt and against the power head, and guide the chain into the guide bar groove.

5. Seat the guide bar tensioner pin in its hole in the guide bar.

7. Tension the chain by screwing the tensioning screw clockwise using the screwdriver tip on the combination tool.

9.Tighten the mounting nut with the combination tool while hold- ing the tip of the guide bar up.

The tension of a new chain must be checked frequently until it is broken in. Continue to check the tension at regular intervals to ensure good performance and a long service life.

Wear causes a chain to become looser with use. Regular tensioning is important to compensate for this wear.

Check the chain tension at least every time you refill the chain oil reservoir.
