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.
