● In the usage of the connecting cable, inspect periodi-
cally and exchange when broken.
Otherwise, the electric shock or short circuit may arise,
which may cause the fire.
● Do not modify the circuit board.
● Do not touch the inside of the circuit board blindly,
which may cause the failure.
● Do not touch the circuit board with wet hand, which
may cause the failure.
● Do not give the useless force to the circuit board.
Bending or twisting force may cause the removal of the
parts on the board.
■ Attachments
● Be sure to use an attachment for power tools.
If attachments for hand tools are used, there is a risk of
breakage which may cause the accident such as scattering
of fragments. Therefore be sure to use attachments for
power tools.
● Be sure not to use an attachment with large mass
Do not use the bit or socket with large mass(heavy or long)
Such mass may be transferred as the false torque to the
tool, which may cause the incorrect tightening.
● Do not use a socket with much wabble.
● Remove the air hose when installing or removing an
attachment.
Be sure to stop compressed air coming in and remove air
hose, then exchange or install an attachment.
Besides, unless protective devices (couplers and etc.)
which can shut down compressed air automatically are
used, before removal of air hose, please be sure to first
close a main cock and stop compressed air from coming in,
and then open a valve on the tool side to discharge
remaining air in the air hose.
