MAINTENANCE AND INSPECTION

CAUTION
Be sure to turned off the switch and remove the battery
before maintenance and inspection.
1. Inspecting the blade
Continued use of a dull or damaged blade will result in
reduced cutting effi ciency and may cause overloading of
the motor. Replace the blade with a new one as soon as
excessive abrasion is noted.
2. 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.
3. 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.
4. Inspecting the carbon brushes (Fig. 12)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
brush can result in motor trouble, replace the carbon
brush with new ones when it becomes worn to or near
the "wear limit" ⓐ. In addition, always keep carbon
brushes clean and ensure that they slide freely whithin
the brush holders.
NOTE
When replacing the carbon brush with a new one, be
sure to use the Hitachi Carbon Brush Code No. 999068.
5. Replacing carbon brushes (Fig. 12)
Take out the carbon brush by fi rst removing the brush
cap and then hooking the protrusion of the carbon brush
with a fl at head screw driver, etc.
When installing the carbon brush, choose the direction
so that the nail ⓑ of the carbon brush agrees with the
contact portion ⓒ outside the brush tube. Then push it in
with a fi nger. Lastly, install the brush cap.
CAUTION
Be absolutely sure to insert the nail of the carbon brush
into the contact portion outside the brush tube. (You can
insert whichever one of the two nails provided).
Caution must be exercised since any error in this
operation can result in the deformed nail of the carbon
brush and may cause motor trouble at an early stage.
6. 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.
7. Storage
Store the power tool 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.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage of batteries with a low charge
may result in performance deterioration, signifi cantly
reducing battery usage time or rendering the batteries
incapable of holding a charge.
However, signifi cantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to fi ve times.
If the battery usage time is extremely short despite
repeated charging and use, consider the batteries dead
and purchase new batteries.
