INSTALLING TRIMMER HEAD
See Figures 1 - 6.
The Bump Feed String 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 bump feed trimmer head housing by rotating the lower
housing counterclockwise so the arrow on the upper housing aligns with
the outside arrow on the bump feed housing.
NOTE: The housing is spring loaded and will self eject when unlocked.
 Separate the upper housing, spring, spool, knob, from lower housing
and set aside.
 Locate the bolt or nut, line guide, and/or spacer required to install the
trimmer head to your attachment. Refer to the Installation Chart for
details.
