WARNING
The saw chain has very sharp edges. Use thick, protective gloves to avoid injury.

3.Fit the chain tensioner nut into the lower hole of the guide bar, then install the chain cover, and fasten the mounting nut to finger tightness. (SE3)
NOTE
When installing the chain cover, be sure to fit the hook completely at the rear end of the cover. (SE4)
4.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. (SE5)
5.Keep holding the guide bar up, tighten the mounting nut firmly with the attached socket wrench.
6.Rotate the saw chain by hand, wearing a protective glove, to see if it turns smoothly without noticeable gap between the tie straps and the guide bar.
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.
