INSTALL THE SAW CHAIN
WARNING:
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
sprocket teeth (Fig. 25).
3. Guide the drive links into the groove (H) and around
the end of the bar (Fig. 25).
4. The chain will be tight so you will have to rotate the
clutch clockwise by hand so the chain engages the
bar sprocket.
5. Replace the outer guide bar plate (I) so the bent
edges (top and bottom) are directed away from the
chain (Fig. 27).
6. Install spike on Chain Brake® cover as shown in
Fig. 27 (Optional accessory).
7. Install the Chain Brake® cover (Fig. 27). Make sure
the chain does not slip off of the bar. Install the 2
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
adjustment is required. Follow instructions in
Saw Chain Tension Adjustment.
