NOTE
○ The recharging time may vary according to the ambient
temperature and power source voltage.
○ If charging takes a long time
– Charging will take longer at extremely low ambient
temperatures. Charge the battery in a warm location
(such as indoors).
– Do not block the air vent. Otherwise the interior will
overheat, reducing the charger's performance.
– If the cooling fan is not operating, contact a HiKOKI
Authorized Service Center for repairs.
4. Disconnect the charger’s power cord from the
receptacle.
5. Hold the charger firmly and pull out the battery.
NOTE
Be sure to pull out the battery from the charger after
use, and then keep it.
Regarding electric discharge in case of new
batteries, etc.
As the internal chemical substance of new batteries and
batteries that have not been used for an extended period is
not activated, the electric discharge might be low when
using them the first and second time. This is a temporary
phenomenon, and normal time required for recharging will
be restored by recharging the batteries 2–3 times.
How to make the batteries perform longer.
(1) Recharge the batteries before they become completely
exhausted. When you feel that the power of the tool
becomes weaker, stop using the tool and recharge its
battery. If you continue to use the tool and exhaust the
electric current, the battery may be damaged and its life
will become shorter.
(2) Avoid recharging at high temperatures. A rechargeable
battery will be hot immediately after use. If such a
battery is recharged immediately after use, its internal
chemical substance will deteriorate, and the battery life
will be shortened. Leave the battery and recharge it
after it has cooled for a while.

authorized Service Center.
MAINTENANCE AND INSPECTION
CAUTION
Be sure to turn off the switch and remove the battery
before maintenance and inspection.
1. Inspecting the tool
Since use of as dull tool will degrade efficiency 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. 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.
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. Cleaning the battery installation compartment and
the battery
After demolishing concrete, if concrete dust has
accumulated on the battery installation compartment
and the battery, clean off the accumulated concrete
dust with an air gun or a dry cloth before using the tool.
(Fig.15)
Also, after cleaning, ensure that the battery can be
installed and removed smoothly from the tool.
CAUTION
Using the tool when the battery is covered with concrete
dust may lead to accidents such as the battery falling
during use.
Furthermore, such use may cause a malfunction or
contact failure between the battery and the terminals.
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,
significantly reducing battery usage time or rendering
the batteries incapable of holding a charge.

However, significantly reduced battery usage time may
be recovered by repeatedly charging and using the
batteries two to five 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.
