SAW CHAIN
TENSION
ADJUSTMENT
WARNING: Unplug chain saw from power source before adjust- ing saw chain tension.
WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain.
WARNING: Maintain proper chain tension always. A loose chain will increase the risk of kickback. A loose chain may jump out of guide bar groove. This may injure operator and damage chain. A loose chain will cause chain, guide bar and sprocket to wear rapidly.
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).
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.
