Semi-automatic nylon line heads must be used only with debris shield

knife can result in trimmer damage, caused by operation with excessive
line length.
Note: Your nylon line head may appear different than nylon line head
shown.
To Advance Trimmer Line
See Maintenance Section for nylon line replacement.
Note: To advance trimmer line, tap trimmer head against the ground
while the head is turning at normal operating speed.
