2. Installing Guide Bar and Saw Chain

The saw chain has very sharp edges. Use thick protective gloves for safety.

1. Loosen the nuts and remove the chain cover.

2. Install the attached spike to the power unit.

3. Gear the chain to the sprocket and, while fitting the saw chain around the guide bar, mount the guide bar to the power unit, Then adjust the position of chain tensioner nut on the chain cover to the lower hole of guide bar.

Note:

Pay attention to the correct direction of the saw chain.

4. Fit the chain cover to the power unit and fasten the nuts to finger tightness.

5. While holding up the tip of the bar, adjust the chain tension by turning the tensioner screw until the tie straps just touch the bottom side of the bar rail.

6. Tighten the nuts securely with the bar tip held up. Then check the chain for smooth rotation and proper tension while moving it by hand. If necessary, readjust with the chain cover loose.

7. Tighten the tensioner screw.

Note :

A new chain will expand its length in the beginning of use. Check and readjust the tension frequently as a loose chain can easily derail or cause rapid wear of itself and the guide bar.
