CARBURETOR ADJUSTMENT
_;_ WARNING: The trimmer head
will be spinning during most of this
procedure. Wear your protective
equipment and observe all safety pre-
cautions. After making mixture adjust-
ments, recheck idle speed.
Carburetor adjustment is critical and if
done improperly can permanently
damage the engine as well as the car-
buretor. If you require further assis-
tance or are unsure about performing
this procedure, call our customer as-
sistance help line at 1-800-235-5878.
Old fuel, a dirty air filter, a dirty fuel fil-
ter, or flooding may give the impres-
sion of an improperly adjusted carbu-
retor. Check these conditions before
adjusting the carburetor.
The carburetor has been carefully set
at the factory. Adjustments may be
necessary if you notice any of the fol-
lowing conditions:
• Engine will not idle. See IDLE SPEED
under adjusting procedure.
• Engine dies or hesitates instead of
accelerating. See ACCELERATION
CHECK under adjusting procedure.
• Loss of cutting power. See MIXTURE
ADJUSTMENT (L or H) under adjusting

ment screw is marked with the letter L,
