remains on PTO shaft (A).
2. Align locking hole in upper plate
with notch in edge of gear
housing and insert head locking
tool (D).

by turning it counterclockwise
until head is tight against adapter
plate (C).
4. Remove locking tool (D).
Semi-automatic nylon line heads
must be used only with debris
shield with cut-off knife. Using
nylon line heads with debris shield
without cutoff 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.
