10 mm nut securely.
7. Insert split pin (L) in hole in PTO shaft, and
bend pin legs around shaft counterclockwise to
retain the 10 mm nut.
IMPORTANT: Never reuse a split pin. Install a new
split pin each time a blade is installed or replaced.
8. Remove the locking tool.
Your ECHO trimmer is now set up to for safe blade
application. Always save your original equipment
shield, upper plate adapter, fasteners, and trimmer
head for re-installation for trimmer line cutting ap-
plication. Do not use a trimmer line head with blade
shield and adapter, otherwise the trimmer head
line will rapidly damage the shield. When convert-
ing back to trimmer line application always remove
and retain blade shield, fasteners, upper, and lower
adapter plates, and spacers from the gear case.
