The Fixed Line/Bladed Trimmer Head installs differently on different
string trimmer attachments. Assembly instructions will vary based
on the style and type of attachment you have. See figures 3 and 4
to determine if you have a curved shaft or straight shaft attachment
and if your attachment comes with or without an arbor. Refer to
the Installation Chart to determine the appropriate items for your
attachment. Be sure to follow the instructions for your attachment
style and type.
NOTE: If you cannot identify the style and type of attachment you
have, contact customer service for assistance.
 Stop the engine or motor, disconnect the spark plug wire for gas
power heads, remove the battery pack for cordless power heads,
or disconnect the plug from the power source for electric power
heads.
 Remove the trimmer head housing by rotating the lower housing
counterclockwise so the arrow on the upper housing aligns with
the post on the lower housing.
 Separate the upper housing from lower housing and set aside.

head to your attachment. Refer to the Installation Chart for details.
