10. Never let the impact wrench turn without a load
when using the universal joint.
If the socket turns without being connected to a load,
the universal joint causes the socket to turn wildly.
You could get hurt or the movement of the socket
could shake the impact wrench so much as to
make you drop it.
11. Always charge the battery at a 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.
12. Do not use the charger continuously.
When one charging is completed, leave the charger
for about 15 minutes before the next charging of
battery.
13. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
14. Never disassemble the rechargeable battery and
charger.
15. 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.
16. Do not dispose of the battery in fire.
If the battery burnt, it may explode.
17. Do not insert object into the air ventilation slots
of the charger.
Inserting metal objects or inflammables into the
charger air ventilation slots will result in electrical
shock hazard or damaged charger.
18. 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.
19. Using an exhausted battery will damage 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 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.
⅜ During work make sure that swarf and dust do not
fall on the battery.
⅜ Make sure that any swarf and dust falling on the
power tool during work do not collect on the battery.
⅜ Do not store an unused battery in a location exposed
to swarf and dust.
⅜ 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.
5. Do not connect directly to an electrical outlets or
car cigarette lighter sockets.
6. Do not use the battery for a purpose other than
those specified.
7. If the battery charging fails to complete even
when a specified recharging time has elapsed,
immediately stop further recharging.
8. Do not put or subject the battery to high
temperatures or high pressure such as into a
microwave oven, dryer, or high pressure container.
9. Keep away from fire immediately when leakage
or foul odor are detected.
10. Do not use in a location where strong static
electricity generates.
11. If there is battery leakage, foul odor, heat
generated, discolored or deformed, or in any way
appears abnormal during use, recharging or
storage, immediately remove it from the equipment
or battery charger, and stop use.
CAUTION
1. If liquid leaking from the battery gets into your
eyes, do not rub your eyes and wash them well
with fresh clean water such as tap water and
contact a doctor immediately.
If left untreated, the liquid may cause eye-problems.
2. If liquid leaks onto your skin or clothes, wash well
with clean water such as tap water immediately.
There is a possibility that this can cause skin irritation.
3. If you find rust, foul odor, overheating, discolor,
deformation, and/or other irregularities when using
the battery for the first time, do not use and return
it to your supplier or vendor.
WARNING
If an electrically conductive foreign object enters the
terminals of the lithium ion battery, a short-circuit may
occur resulting in the risk of fire. Please observe the
following matters when storing the battery.
⅜ Do not place electrically conductive cuttings, nails,
steel wire, copper wire or other wire in the storage
case.
⅜ Either install the battery in the power tool or
store by securely pressing into the battery cover
until the ventilation holes are concealed to prevent
short-circuits (See Fig. 1).
