MAINTENANCE AND REPAIR INSTRUCTIONS
SPECIFICATIONS
LUBRICATING BLADE
1. For easier operation and longer blade life, lubricate the hedge
trimmer attachment blade before and after each use. Before
lubricating, be sure the powerhead is turned OFF. Apply light
machine oil along the edge of the top blade strap (Fig. 6).
2. Occasionally, you should oil your hedge trimmer attachment
during use. Before oiling, stop hedge trimmer, then oil. You
then can resume trimming. Do not oil while hedge trimmer
attachment is running.
OTHER MAINTENANCE
1. 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 it does interfere, turn the
powerhead off and use a fine toothed file or sharpening stone
to remove the nick.
2. If you drop the trimmer, carefully inspect it for damage. If the
blade is bent, housing cracked, or handles broken or if you
see any other condition that may affect the trimmer’s
operation contact a professional service center for repairs
before putting it back into use.
3. 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.
4. With the unit powered off (and the spark plug disconnected),
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.
NOTE: To assure product SAFETY and RELIABILITY, repairs,
maintenance and adjustments should be performed by an
professional service center using identical replacement
parts.

serious personal injury.
