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.
