1.
Before adjusting chain, make sure
guide bar nuts are only finger tight. Also
make sure adjusting block is in oval
adjusting hole on guide bar.
2.
Turn adjusting screw clockwise until all
slack is out of chain (see Figure 5).
Note:
There should be no gap between
side links of chain and bottom of guide
bar (see Figure 6).

Wearing protective gloves, move chain
around guide bar. Chain should move
freely. If chain does not move freely,
loosen chain by turning adjusting screw
counterclockwise.

After chain tension is correct, tighten
guide bar nuts firmly. If not, guide bar
will move and loosen chain tension.
This will increase the risk of kickback.
This can also damage saw.
Note:
A new
chain will stretch. Check new chain
after first few minutes of operation.
Allow chain to cool down. Readjust
