CAUTiON
Bar and chain are sized appropriately to each saw and gear
drive for chain, ONLY use approved compatible components for
this saw.

toward gear drive clutch, rotate into position with two bolt
holes protruding through slot in bar.

wrapping blade around gear driven clutch. Position blade in
alignment with gear sprocket. Then wrap blade around front

inserted in the mating guide bar hole, tighten two 13mm nuts
to hand tight.
