Blade Maintenance (Fig. A, H)
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.H), 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 pack
7
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.
Blade Lubrication (Fig. A)
1. After use, remove thebattery pack

.
2. Carefully apply a resin solvent to the exposedblades.
3. Insert the battery pack and turn the tool vertical with
the blades toward the ground and run the tool for a few
seconds to fully disperse thelubrication.

through the twigs is most effective. A slight downward tilt of
the blade in the direction of motion gives the bestcutting.
