*5 About the mode change function
With Auto mode, you can lower noise and vibration by
lowering the maximum number of revolutions while in a
no-load state.
While in Auto mode, the number of revolutions will be
raised if the load becomes greater during operation.
On the other hand, the number of revolutions will be
lowered if the load decreases during operation.
NOTE
○
To enable mode changes, pull the switch once after
installing the battery.
○
The set mode remains set even if the power is turned o
ff
.
○
Do not give a strong shock to the switch panel or break it.
It may lead to a trouble.
Pressing the Auto mode switch will change the operating
mode back and forth between Auto mode and Full-Speed
mode. In Full-Speed mode, the number of revolutions is
controlled so that it always remains constant.
Set the mode according to work application.
*6 Grinding angle and grinding method
Press down the machine evenly on the surface and
move back and forth so that the surface of the workpiece
does not become too hot.
Rough grinding: position the machine at an angle of
15°–30° for the best working results.
When the grinding stone is new, its corner may dig in
when it is pushed forward, so pull back during use.
(
Fig. 13-a
)
Once the wheel edge is worn, the workpiece can be
ground in both directions. (
Fig. 13-b
).
*7 Cutting work
Always work against the run of the disc. Otherwise there
is the danger of the machine kicking back from the cut
out of control. Guide the machine evenly at a speed
suitable for the material being processed. Do not tilt,
apply excessive force or sway from side to side.
*8 Remaining battery indicator (Product)
When using a battery with a remaining battery indicator,
please refer to the indicator lamp on the battery for the
battery remaining power.
MAINTENANCE AND INSPECTION
WARNING
Be sure to turned o
ff
the switch and remove the battery
before maintenance and inspection.
1. Inspecting the depressed center wheel
Ensure that the depressed center wheel is free of cracks
and surface defects.
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. Filter cleaning and inspection (Fig. 16)
WARNING
Wear protective glasses and a dust mask when cleaning
the
fi
lter with an air gun.
Failure to do so may result in inhalation or exposure of
the eyes to debris or dust.
After use, remove any debris or dust adhered to the
fi
lter
using a soft brush. Check the
fi
lter periodically to ensure that
it is free of scratching, chipping, or tearing. Replace with a
new
fi
lter if the
fi
lter is damaged in any way.
NOTE
○
If the mesh is clogged and the debris or dust cannot be
removed, detach the
fi
lter and clean it with an air gun,
etc.
○
After cleaning, make sure to securely attach the
fi
lter.
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.
NOTE
In order to expel debris and dust, periodically run the
motor with no load.
5. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
6. Cleaning on the outside
When the cordless disc grinder 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.
Important notice on the batteries for the HiKOKI
cordless power tools
Please always use one of our designated genuine
batteries. We cannot guarantee the safety and
performance of our cordless power tool when used with
batteries other than these designated by us, or when
the battery is disassembled and modi
fi
ed (such as
disassembly and replacement of cells or other internal
parts).
NOTE
Due to HiKOKI’s continuing program of research and
development, the speci
fi
cations herein are subject to
change without prior notice.
