SAW CHAIN TENSION
ADJUSTMENT
!WARNING
Unplug chain saw from power source before adjusting 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.
Note: 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 3, page 6). Also make sure adjust- ing block is in oval adjusting hole on guide bar (see Figure 3 and 4, page 6).
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.

FILLING OIL TANK
1.Remove oil cap.
2.Fill oil tank with Echo bar and chain oil.
3.Replace oil cap at once. Tighten oil cap firmly for good seal. This will avoid oil seepage from tank.
4.Wipe off excess oil.
Note: It is normal for oil to seep when saw is not in use. Empty oil tank after each use to prevent seepage.
