Blade Maintenance (Fig. J)
.
The cutting blades are made from high quality, hardened
steel and with normal usage, they will not require
resharpening. However, if you accidentally hit a wire fence
(Fig. J), stones, glass, or other hard objects, you may put a
nick in the blade. There is no need to remove this nick as long
as it does not interfere with the movement of the blade. If
it does interfere, remove the battery and use a fine toothed
file or sharpening stone to remove the nick. If you drop the
trimmer, carefully inspect it for damage. If the blade is bent,
housing cracked, handles broken or if you see any other
condition that may affect the tool's operation contact your
local authorized service center for repairs before putting it
back into use.

blades toward the ground and run the tool for a few
seconds to fully disperse the lubrication.
