Maintenance And Inspection - Hitachi CH 10DL Handling Instructions Manual

○ During work (for example, when taking rests) do not
leave the tool in a place exposed to direct sunlight or high
temperature. This will prevent proper cooling and could
result in damage.
○ Do not use the tool for work that exceeds its capacity.
Such operation could cause the motor to lock up or slow
down and will damage it.
○ Do not lower the front end of the blade to prevent sand,
gravel or soil from entering the blade and damaging it by
making it less sharp.
Trimming tall grass
Attempting to cut tall grass at one go will expose the
blade to excessive load and wear the blade. First remove
1/3 of the height starting from the top before trimming it to
the desired height.
Trimming around stone walls and curbs
When trimming around curbs, move the blade sideways
along the curb. (Fig. 24)
This makes it possible to trim without leaving untrimmed
edges.
3. Continuous operating time
Approx. 30 minutes (depending on the work conditions)

MAINTENANCE AND INSPECTION

WARNING
○ Be sure to turn the tool off and remove the battery
from the tool before making inspections or carrying out
maintenance.
○ Do not disassemble to blade. Failure to heed this warning
may result in injury.
○ 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. 19)
Move an iron fi le in the direction of the arrow for a rough
sharpening then use an oil stone to give the blade a good
fi nish.
(1) Use a fi ne iron fi le 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 power tool 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 power tool in a place in which the temperature
is less than 40°C and out of reach of children.
