CHAIN TENSION

(Including units with chain already installed)

WARNING: Wear protective gloves when handling chain. The chain is sharp and can cut you even when it is not moving.

NOTE: When adjusting chain tension, make sure the bar nuts are finger tight only. Attempting to tension the chain when the bar nuts are tight can cause damage.

Checking the tension:

Use the screwdriver end of the chain adjust- ment tool (bar tool) to move chain around guide bar. If the chain does not rotate, it is too tight. If the chain is too loose, it will sag below the bar.

Adjusting the tension:

Chain tension is very important. Chains stretch during use. This is especially true during the first few times you use your saw. Always check chain tension each time you use and refuel your saw.

An adjusting screw (located on the guide bar) is used to adjust the tension of the chain (see illustration).

1.Loosen bar nuts until they are finger tight against the clutch cover.

2.Turn adjusting screw clockwise until chain solidly contacts bottom of guide bar rail.
