REPLACING GUIDE BAR AND CHAIN

WARNING: Always use protective gloves when handling

the saw chain.

1.Spread chain out in a loop with cutting edges (E) pointing CLOCKWISE around loop (Fig. 24).

2.Slip the chain around the sprocket (F) behind the clutch (G). Make sure the links fit between the sprock- et teeth (Fig. 25).

3.Place the slotted end of the guide bar over the two bar bolts (D, Fig. 23). Be sure adjusting tang

(J, Fig. 23) is in lower adjusting hole of the bar.

4.Guide the drive links into the groove (H) and around the end of the bar (Fig. 25).

5.The chain will be tight so you will have to rotate the clutch clockwise by hand so the chain engages the bar sprocket.

6.Replace the outer guide bar plate (I) so the bent edges (top and bottom) are directed away from the chain (Fig. 27).

7.Install the Chain Brake® cover (Fig. 27). Make sure the chain does not slip off of the bar. Install the 2 bar retaining nuts hand tight and follow instructions in Saw Chain Tension Adjustment.

NOTE: The guide bar retaining nuts are installed only hand tight at this point because saw chain adjust- ment is required. Follow instructions in Saw Chain Tension Adjustment.
