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.

CAUTION
The lever is attached to a strong spring. Be very careful
not to get your fingers caught when pushing the lever
down.
*2 Mounting dust collection adapter
For use with MSU93D only
*3 Switch operation
When the switch is turned on, the LED light blinks at the
same time.
*4 Adjusting operating speed
You can change the vibration frequency between 6000
to 20000 min-

by adjusting the dial from "1" to "6".
Adjust the dial for the speed that best suits your task
conditions and materials.
*5 Select accessories that are suited to a specific task. For
details contact HiKOKI Authorized Service Center.
MAINTENANCE AND INSPECTION
WARNING
Be sure to turn off the switch and remove the battery
before maintenance and inspection.
1. Inspecting the application tool
Continued use of a dull or damaged application tool will
result in reduced cutting efficiency and may cause
overloading of the motor. Replace the application tool
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. 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.
