SAW CHAIN TENSION
ADJUSTMENT
Note: For pre assembled models, the saw chain tension is
properly set at factory. A new chain will stretch. Check new
chain after first few minutes of operation. Allow chain to cool
down. Follow steps below to readjust saw chain tension.
1. Before adjusting chain, make sure guide bar nuts are only
finger tight (see Figure 16, page 11). Also make sure
adjusting block is in oval adjusting hole on guide bar (see
Figure 16 and 17, page 11).
2. Turn adjusting screw clockwise until all slack is out of
chain (see Figure 14).
Note: There should be no gap between side links of chain
and bottom of guide bar (see Figure 15)
3. 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.
4. 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 chain tension.
