Stop the motor, remove the battery pack for cordless
power heads, or disconnect the plug from the power
source for electric power heads.
Rotate the lower housing counterclockwise so the arrow
on the upper housing aligns with the outside arrow on
the bump feed housing.

when unlocked. It is not necessary to remove the upper
string head housing from the drive shaft.
Push the spool and bump knob through the string head
housing and remove the string from the spool.
If replacing the bump knob, remove the old knob from
the spool. Align the knob ribs with the spool slots and

replacing the bump knob, skip this step.
Insert the bump knob and spool assembly through the
opening in the string head housing.
