PRECAUTIONS ON USING IMPACT WRENCH
1. When using the tool at a hight, make sure that there
is nobody below.
2. Use earplugs if using for a long time use.
3. Switch the reversing switch only after the motor
has stoped when it is necessary to change the
direction of the rotation.
4. Use a step up transformer when a long extension
cable is used.
5. Confirm the tightening torque by a torque wrench
before use in order to assertain the correct tightening
torque to be used.
6. Assemble the socket securely to the impact wrench
with the socket pin and ring.
7. Confirm whether the socket has any cracks in it.
8. Always hold the body and side handles of the
impact wrench firmly. Otherwise the counterforce
