English
7
7. 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.
8. Do not use the charger continuously.
When one charging is completed, leave the charger for about 15
minutes before the next charging of battery.
9. Do not allow foreign matter to enter the hole for connecting the
rechargeable battery.
10. Never disassemble the rechargeable battery and charger.
11. 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.
12. Do not dispose of the battery in fire.
If the battery burnt, it may explode.
13. 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.
14. 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.
15. Using an exhausted battery will damage the charger.
PRECAUTIONS FOR CORDLESS IMPACT
WRENCH (WR14DBDL / WR18DBDL)
1. This is a portable tool for tightening and loosening bolts and nuts.
Use it only for these operation.
2. Use the earplugs if using for a long time.
3. One-hand operation is extremely dangerous; hold the unit firmly with
both hands when operating.
4. Check that the socket is not cracked or broken.
Broken or cracked sockets are dangerous. Check the socket before using
it.
5. Secure the socket with the socket pin and the ring.
If the socket pin or ring securing the socket is damaged, the socket may
come off from the impact wrench, which is quite dangerous. Do not use
socket pins or rings that are deformed, worn out, cracked, or in any other
way damaged. Always make sure to install the socket pin and ring in the
correct position.
6. Check the tightening torque.
The appropriate torque for tightening a bolt depends on the material
the bolt is made of, its dimensions, grade, etc.
Also, the tightening torque generated by this impact wrench depends
on the materials and dimensions of the bolt, how long the impact wrench
is applied for the way in which the socket is installed, etc.
Also the torque when the battery has just been charged and when it
is about to run out are slightly different. Use a torque wrench to check
that the bolt has been tightened with the appropriate torque.
7. Stop the impact wrench before switching the direction of rotation.
Always release the switch and wait for impact wrench to stop before
switching the direction of rotation.
8. Never touch the turning part.
Do not allow the turning socket section to get near your hands or any
other part of your body. You could be cut or caught in the socket. Also,
be careful not to touch the socket after using continuously it for a long
time. It gets quite hot and could burn you.
9. 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.
10. 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.
11. Do not use the charger continuously.
When one charging is completed, leave the charger for about 15
minutes before the next charging of battery.
12. Do not allow foreign matter to enter the hole for connecting the
rechargeable battery.
13. Never disassemble the rechargeable battery and charger.
14. 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.
15. Do not dispose of the battery in fire.
If the battery burnt, it may explode.
16. 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.
17. 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.
18. 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. (BSL1430, BSL1830)
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
