CARBURETOR ADJUSTMENT

_i 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 ISLE SPEED under adjusting procedure.

•Engine dies or hesitates instead of accelerating. See ACCELERATION CHECK under adjusting procedure.

•Loss of cutting power. See MIXTURE ADJUSTMENT under adjusting procedure.
