If you drop the trimmer, carefully inspect it for damage. If the blade is
bent or cracked, handles broken or if you see any other condition that
may affect the trimmer’s operation, it must be repaired before putting it
back into use. Call our customer service help line at 1-800-313-5111 for
assistance.
CAUTION: Do not at any time let brake fluids, gasoline, petroleum
based products, penetrating oils, etc., come in contact with plastic parts.
They contain chemicals that can damage, weaken or destroy plastic.
Make sure the battery is detached from the unit, then use only mild soap
and a damp cloth to clean the tool. Never let any liquid get inside the
tool; never immerse any part of the tool into a liquid.
IMPORTANT: To assure product SAFETY and RELIABILITY, repairs,
maintenance and adjustment should be performed by a qualified
individual using only identical replacement parts.
The cutting blades are made from high quality, hardened steel and with
normal usage, they will not require re-sharpening. 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 doesn’t interfere with the movement of the blade. If it does interfere,
make sure the battery is detached from the unit and use a fine toothed
file or sharpening stone to remove the nick.
Fertilizers and other garden chemicals contain agents which greatly
accelerate the corrosion of metals Do not store the tool on or adjacent to
fertilizers or chemicals.
LUBRICATE BLADES - Stop the unit and
remove the battery pack. Then remove any
debris on blades. Apply a light machine oil
along the edge of the top and bottom blade
supports. Make sure handles remain clean and
dry.
