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

WRENCH

1. Hold power tool by insulated gripping surfaces,

when performing an operation where the fastener

may contact hidden wiring. Fasteners contacting

a "live" wire may make exposed metal parts of

the power tool "live" and could give the operator

an electric shock.

2. This is a portable tool for tightening and loosening

bolts and nuts. Use it only for these operation.

3. Use the earplugs if using for a long time.

4. One-hand operation is extremely dangerous; hold

the unit firmly with both hands when operating.

5. Check that the socket is not cracked or broken.

Broken or cracked sockets are dangerous. Check

the socket before using it.

6. 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.

7. 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.

8. 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.

9. 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.

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.
