SPECIFIC SAFETY RULES
1. Hold power tools by insulated gripping
surfaces when performing an
operation where the cutting tool may
contact hidden wiring or its own cord.
Contact with a "live" wire will make
exposed metal parts of the tool "live"
and shock the operator. To reduce the
risk of injury, always check the work
area for hidden wires before coring.
2. Wear ear protectors with diamond
core drills. Exposure to noise can
cause hearing loss.
3. Use auxiliary handles supplied with the
tool. Loss of control can cause
personal injury.
4. Maintain tools carefully. Keep handles
dry, clean and free from oil and
grease. Keep cutting edges sharp and
clean. Follow instructions for lubricating
and changing accessories.
Periodically inspect tool cords and
extension cords for damage. Have
damaged parts repaired or replaced
by a qualified service facility.
5. Maintain labels and nameplates. These
carry important information. If
unreadable or missing, obtain a
replacement .
6. WARNING! Some dust created by
power sanding, sawing, grinding,
drilling, and other construction
activities contains chemicals known to
cause cancer, birth defects or other
reproductive harm. Some examples of
these chemicals are:
  •leadfromlead-basedpaint
.  •crystallinesilicafrombricksand
cement and other masonry
products, and
  •arsenicandchromiumfrom
chemically-treated lumber. Your risk
from these exposures varies,
depending on how often you do this
type of work. To reduce your exposure
to these chemicals: work in a well
ventilated area, and work with
approved safety equipment, such as
those dust masks that are specifically
designed to filter out microscopic
particles.
7. Provide proper protection for people
and property below the coring area
when coring through floors.
8. Always use core bits and drill bits
within the maximum allowed size on
the nameplate. Oversized bits will
cause damage to the motor and
excessive torque leading to loss of
control.
9. Use only recommended bits, rated at
the machine’s maximum rated RPM or
higher with correct coupling thread.
10. Always position your body and arms in
