IMPORTANT SAFETY INSTRUCTIONS FOR USE
OF THE CORDLESS IMPACT DRIVER/WRENCH
WARNING:
Death or serious bodily injury could result from
improper or unsafe use of the cordless impact
driver/wrench. To avoid these risks, follow these
basic safety instructions:
1. Never use this impact driver/wrench handle for any
application other than those in this manual.
2. Never place hands or other body parts near the
drill bit or chuck during operation.
Hold the impact driver/wrench by its handle only.
3. When working in high places, always make sure
that ther is no one below before starting to work.
4. Always wear eye and ear protection when you
work.
5. Always install the driver bit securely. A loose bit is
dangerous because it can come loose while you
are working. (WH18DSDL)
6. Always use the driver bit that matches the screw
size. (WH18DSDL)
7. Always have the screw you are screwing in and
this impact driver in a straight line. Working with
this impact driver at an angle to the screw can
damage the screw head and will not give the
prescribed tightening torque. (WH18DSDL)
8. Confirm whether the socket has any crack in it.
(WR18DSDL)
9. Attach the hex. socket securely onto the anvil. If
the hex. socket is insufficiently secured, it may drop
out and cause an accident. For hex. socket
attachment refer to “OPERATION”. (WR18DSDL)
10. Confirm the tightening torque by a torque wrench
before use in order to ascertain the correct
tightening torque to be used. (WR18DSDL)
11. If a universal joint is used, be sure not to operate
the unit in a no-load condition. Operating in this
condition is dangerous. When the socket section
spins around it may cause injury to hands or
bodies, or the resulting intense vibration may
cause the user to drop the tool. (WR18DSDL)
12. Be careful that foreign matters do not block the
holes located on both sides of the handle. Also do
not close the holes with a tape. The holes act an
important role. (WR18DSDL)
