5.Tighten the nuts securely with the bar tip held up (12 ~ 15 N·m). Then check the chain for smooth ro- tation and proper tension while moving it by hand. If necessary, readjust with the chain cover loose.
6.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 itseif and the guide bar.
