over the direction it is facing, and then set the saw
chain in the guide bar groove. (Fig. 5)
(3) Set the clip on the side cover in the housing, put on
the side cover, rotate the tension dial, align the chain's
tension pin with the hole on the guide bar and attach it

(2) Adjust the saw chain tension so that the gap between
the edge of the chain's drive links and the guide bar is
between 0.5 mm and 1 mm when the chain is lightly
raised from the center of the guide bar. (Fig. 10)
(3) Once adjustment has been completed, raise the end of
the guide bar and fi rmly tighten the knob. (Fig. 9)
(4) Rotate the saw chain approximately one half of a
