Bar and chain are sized appropriately to each saw and gear
drive for chain, ONLY use approved compatible components for
this saw.
1. Replace new bar where text is upright. Start by inserting bar
toward gear drive clutch, rotate into position with two bolt
holes protruding through slot in bar.
2. Install new blade with teeth facing correct direction. Start by
wrapping blade around gear driven clutch. Position blade in
alignment with gear sprocket. Then wrap blade around front

well as bar groove.

aligns with the mating hold on the guide bar.

turn (clockwise). Align brake onto clutch housing and two
studs making sure the studs align with mating holes on clutch
cover (Fig. 29).

inserted in the mating guide bar hole, tighten two 13mm nuts
to hand tight.
6. While holding up the tip of the bar, tension saw chain by
turning the tension screw clockwise (Right) until the tie straps
just touch the bottom side of the bar rail (Fig. 31).
7. Once proper chain tension has been achieved, using a 13mm
wrench or socket, fully tighten two nuts.
