MAINTENANCE AND INSPECTION
1. Inspecting the tool
Since use of as dull tool will degrade e
ffi
ciency and
cause possible motor malfunction, sharpen or replace
the tool as soon as 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 HiKOKI Carbon Brush Code No. 999054.
5. Replacing carbon brushes
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 angle drill 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 and battery in a place in which
the temperature is less than 40°C and out of reach of
children.
NOTE
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully
charged before storing them.
Prolonged storage (3 months or more) of batteries with
a low charge may result in performance deterioration,
signi
fi
cantly reducing battery usage time or rendering
the batteries incapable of holding a charge.
However,
signi
fi
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.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
