Use and Care Manual

SPECIFIC SAFETY RULES
•Diamond coring equipment requires the use
of water. When drilling overhead, use a liquid
collection system. Water in contact with the elec-
trical system of the tool may make exposed metal
parts of the tool "live" and could give the operator
an electric shock.
•Operate power tool by insulated grasping sur-
faces, when performing an operation where the
cutting accessory may contact hidden wiring
or its own cord. Cutting accessory contacting a
"live" wire may make exposed metal parts of the
power tool "live" and could give the operator an
electric shock.
•Wear ear protectors when diamond drilling.
Exposure to noise can cause hearing loss.
•When the bit is jammed, stop applying down-
ward pressure and turn off the tool. Investigate
and take corrective actions to eliminate the cause
of the bit jamming.
•When restarting a diamond drill in the work-
piece check that bit rotates freely before
starting. If the bit is jammed, it may not start, may
overload the tool, or may cause the diamond drill
to release from the workpiece.
•When securing the drill stand with anchors and
fasteners to the workpiece, ensure that the an-
choring used is capable of holding and restrain-
ing the machine during use. If the workpiece is
weak or porous, the anchor may pull out causing
the drill stand to release from the workpiece.
•When securing the drill stand with a vacuum
pad to the workpiece, install the pad on a
smooth, clean, non-porous surface. Do not
secure to laminated surfaces such as tiles
and composite coating. If the workpiece is not
smooth, fl at or well affi xed, the pad may pull away
from the workpiece.
•Ensure there is suffi cient vacuum level before
drilling. If the vacuum level is insuffi cient, the pad
may release from the workpiece.
•Never perform overhead drilling with the
machine secured only by the vacuum pad. If
the vacuum is lost, the pad will release from the
workpiece.
•When drilling through walls or ceilings, ensure
to protect persons and the work area on the
other side. The bit may extend through the hole
or the core may fall out on the other side.
•Always use a liquid collection system when
drilling overhead. Water in contact with an elec-
trical system of the tool may make exposed metal
parts of the tool "live" and could give the operator
an electric shock.
•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 dam-
aged parts repaired or replaced by a MILWAUKEE
service facility.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
• 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 spe-
cially designed to fi lter out microscopic particles.
