derside of shield) is sharp and can cut you.

ASSEMBLY INFORMATION - -
TRIMMER HEAD
NOTE:
Remove the blade before attaching the
trimmer head. To remove blade, align hole in
the dust cup with the hole in the side of the
gearbox by rotating the blade. Insert a small
screwdriver into aligned holes. This will keep
the shaft from turning while loosening the blade
nut. Remove blade nut by turning clockwise.
Remove the screwdriver. Remove both wash-
ers and blade. See INSTALLATION OF THE
METAL BLADE for illustrations. Be sure to store
all parts and instructions for future use.
