up place — out of reach or children. Store tools and
charger in a place in which the temperature is less
than 40°C.
5. Don't abuse cord. Never carry charger by cord or yank
it to disconnect from receptacle. Keep cord from heat,
oil and sharp edges.
6. When the charger is not in use or when being
maintained and inspected, disconnect the power cord
of the charger from the receptacle.
7. To avoid danger, always use only the specifi ed
charger.
8. Use only genuine HITACHI replacement parts.
9. Do not use power tools and charger for applications
other than those specifi ed in the Handling Instructions.
10. To avoid personal injury, use only the accessories
or attachment recommended in these handling
instructions or in the HITACHI catalog.
11. If the supply cord is damaged, it must be replaced
by the manufacture or its service agent or a similarly
qualifi ed person in order to avoid a hazard.
Let only the authorized service center do the
repairing. The Manufacture will not be responsible
for any damages or injuries caused by repair by the
unauthorized persons or by mishandling of the tool.
12. To ensure the designed operational integrity of power
tools and charger, do not remove installed covers or
screws.
13. Always use the charger at the voltage specifi ed on the
nameplate.
14. Always charge the battery before use.
15. Never use a battery other than that specifi ed. Do not
connect a usual dry cell, a rechargeable battery other
than that specifi ed or a car battery to the power tool.
16. Do not use a transformer containing a booster.
17. Do not charge the battery from an engine electric
generator or DC power supply.
18. Always charge indoors. Because the charger and
battery heat slightly during charging, charge the
battery in a place not exposed to direct sunlight;
where the humidity is low and the ventilation is good.
19. Use the exploded assembly drawing on this handling
instructions only for authorized servicing.
PRECAUTIONS FOR CHARGER
1. Always charge the battery at an ambient temperature
of 0–40°C. A temperature of less than 0°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.
