MAINTENANCE AND INSPECTION
WARNING
⅜ Be sure to turn the tool off and remove the battery
from the tool before making inspections or carrying
out maintenance.
⅜ Do not disassemble to blade. Failure to heed this
warning may result in injury.
⅜ Use gloves, or cloth to protect your hands when
handling the blade. Failure to heed this warning may
result in injury.
1. Sharpening the blade (Fig. 15)
Move an iron file in the direction of the arrow for a
rough sharpening then use an oil stone to give the
blade a good finish.
(1) Use a fine iron file or one of intermediate coarseness.
(2) Coat the oil stone with machine oil (bicycle oil or the
like).
(3) Use a whetstone to gently remove any burrs from
the back of the blade edge.
When to sharpen the blade
While this will vary the type of trees that are trimmed
and how often it is used, it is a good idea to sharpen
the blade about once a year to maintain a sharp
edge.
NOTE
Do not use water for cleaning the blade to prevent
rust or other damage.
2. Lubricating the blade
During trimming, sap adhering to the blade edge will
increase load and wear down the battery more rapidly.
Use machine oil (or bicycle oil or the like) to lubricate
the blade and wipe the blade with a cloth. To prevent
the blade from rusting, be sure to lubricate the blade
after use and when it will not be used for an extended
period of time before placing it in the blade case.
3. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
4. Maintenance of the motor
The motor unit winding is the very “heart” of the
power tool.
Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
5. Cleaning on the outside
When the hedge trimmer is stained, wipe with a soft
dry cloth or a cloth moistened with soapy water. Do
not use chloric solvents, gasoline or paint thinner, for
they melt plastics.
6. Storage
Store the hedge trimmer in a place in which the
temperature is less than 40°C and out of reach of
children.
NOTE
Make sure that the battery is fully charged when
stored for a long period (3 months or more). The
battery with smaller capacity may not be able to be
charged when used, if stored for a long period.
