PRECAUTIONS FOR CORDLESS IMPACT
WRENCH
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.
