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 be-

fore you start the chain saw.

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.
