3.An adjusting pin and screw is used to ad- just the tension of the chain. It is very im- portant when assembling the bar, that the pin located on the adjusting screw aligns into a hole in the bar. Turning the screw will move the adjustment pin up and down the screw. Locate this adjust- ment before you begin mounting the bar onto the saw. See illustration.

4.Turn the adjusting screw counterclock- wise to move the adjusting pin almost as far as it will go to the rear. This should al- low the pin to be near the correct posi- tion. Further adjustment may be neces- sary as you mount the bar.

5.Slide guide bar behind clutch drum until guide bar stops against clutch drum sprocket.

8.Fit bottom of drive links between the teeth in the sprocket in the nose of the guide bar.

9.Fit chain drive links into bar groove.

10.Pull guide bar forward until chain is snug in guide bar groove. Ensure all drive

links are in the bar groove.

11Now, install chain brake making sure the adjusting pin is positioned in the lower hole in the guide bar. Remember this pin moves the bar forward and backward as

the screw is turned.

12.Install chain brake nuts and finger tighten only. Once the chain is tensioned, you will need to tighten chain brake nuts.

CHAIN TENSION (Including units with chain already installed)

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 combination screwdriver/wrench tool to move the chain around the bar. If the chain does not rotate, it is too tight. If too loose, the chain will sag be- low the bar.
