For the warning label, refer to your Hitachi Authorized
Service Center.
25. When working, if local rules or regulations apply,
comply with the same.
26. Do not use the product if the tool or the battery terminals
(battery mount) are deformed.
Installing the battery could cause a short circuit that
could result in smoke emission or ignition.
27. Keep the tool’s terminals (battery mount) free of swarf
and dust.
○
Prior to use, make sure that swarf and dust have not
collected in the area of the terminals.
○
During use, try to avoid swarf or dust on the tool from
falling on the battery.
○
When suspending operation or after use, do not leave
the tool in an area where it may be exposed to falling
swarf or dust.

smoke emission or ignition.
PRECAUTIONS FOR BATTERY AND
CHARGER
1. Always charge the battery at an ambient temperature
of -10–40°C. A temperature of less than -10°C will
result in over charging which is dangerous. The battery
cannot be charged at a temperature greater than 40°C.
The most suitable temperature for charging is that of
20–25°C.
2. Do not use the charger continuously.
When one charging is completed, leave the charger for
about 15 minutes before the next charging of battery.
3. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
4. Never disassemble the rechargeable battery or
charger.
5. Never short-circuit the rechargeable battery.
Short-circuiting the battery will cause a great electric
current and overheat. It results in burn or damage to the
battery.
6. Do not dispose of the battery in
fi
re.
If the battery is burnt, it may explode.
7. Using an exhausted battery will damage the charger.
8. Bring the battery to the shop from which it was
purchased as soon as the post-charging battery life
becomes too short for practical use. Do not dispose of
the exhausted battery.
9. Do not insert objects into the air ventilation slots of the
charger.
Inserting metal objects or
fl
ammable into the charger
air ventilation slots will result in an electrical shock
hazard or damage to the charger.
CAUTION ON LITHIUM-ION BATTERY
To extend the lifetime, the lithium-ion battery equips with
the protection function to stop the output.
In the cases of 1 to 3 described below, when using this
product, even if you are pulling the switch, the motor may stop.
This is not the trouble but the result of protection function.
1. When the battery power remaining runs out, the motor
stops.
In such a case, charge it up immediately.
2. If the tool is overloaded, the motor may stop. In this
case, release the switch of tool and eliminate causes of
overloading. After that, you can use it again.
3. If the battery is overheated under overload work, the
battery power may stop.
In this case, stop using the battery and let the battery
cool. After that, you can use it again.
Furthermore, please heed the following warning and
caution.
WARNING
In order to prevent any battery leakage, heat generation,
smoke emission, explosion and ignition beforehand,
please be sure to heed the following precautions.
1. Make sure that swarf and dust do not collect on the battery.
○
During work make sure that swarf and dust do not fall
on the battery.
○
Make sure that any swarf and dust falling on the power
tool during work do not collect on the battery.
○
Do not store an unused battery in a location exposed to
swarf and dust.
○
Before storing a battery, remove any swarf and dust
that may adhere to it and do not store it together with
metal parts (screws, nails, etc.).
2. Do not pierce battery with a sharp object such as a
nail, strike with a hammer, step on, throw or subject the
battery to severe physical shock.
3. Do not use an apparently damaged or deformed battery.
4. Do not use the battery in reverse polarity.
