Blade Maintenance (Fig. A, J)

WARNING: Use gloves and proper eye protection while
removing, sharpening, and installing blade.
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, 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 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.
1. Remove the battery 
2. Remove blade from pruner. See instructions for
Removing and Installing Blade.
3. Wear proper eye protection and gloves and be careful
not to cut yourself.

with a fine tooth file 
stone (not included), maintaining the angle of the
original cutting edge of the cutting blade.
