5) Battery tool use and care
a) Recharge only with the charger specified by the
manufacturer.
A charger that is suitable for one type of battery
pack may create a risk of fire when used with
another battery pack.
b) Use power tools only with specifically designated
battery packs.
Use of any other battery packs may create a risk
of injury and fire.
c) When battery pack is not in use, keep it away from
other metal objects like paper clips, coins, keys,
nails, screws, or other small metal objects that can
make a connection from one terminal to another.
Shorting the battery terminals together may
cause burns or a fire.
d) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause
irritation or burns.
6) Service
a) Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool
is maintained.
PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach of
children and infirm persons.
PRECAUTIONS FOR CORDLESS IMPACT
DRIVER
1. This is portable tool for tightening and loosenig
screws. 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. After installing the driver bit, pull lightly out the
bit to make sure that it does not come loose. If
the bit is not installed properly, it can come loose
during use, which can be dangerous.
5. Use the bit that matches the screw.
6. Tightening a screw with the impact driver at an
angle to that screw can damage the head of the
screw and the proper force will not be transmitted
to the screw. Tighten with this impact driver lined
up straight with the screw.
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.
5
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
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.
