fuel/air mix to provide maximum Saw performance. Your
Carburetor may need resetting, however, if you notice any of
these conditions:
a, Chain moves with Saw engine idle,
bo Loss of cutting power which is not corrected by Air' Filter'
or Muffler Screen cleaning,
c, Saw engine dies or hesitates on acceleration,
NOTE: CARELESS ADJUSTMENTS CAN SERIOUSLY
