that can make a connection from one terminal
to another. Shorting the battery terminals together
may cause burns or a re.
• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact ac-
cidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
• Do not use a battery pack or tool that is dam-
aged or modied. Damaged or modied batteries
may exhibit unpredictable behavior resulting in re,
explosion or risk of injury.
• Do not expose a battery pack or tool to re or
excessive temperature. Exposure to re or tem-
perature above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specied in the instructions. Charging
improperly or at temperatures outside the specied
range may damage the battery and increase the risk
of re.
SERVICE
• Have your power tool serviced by a qualied
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
CORE DRILL
Safety instructions for all operations
•Use the auxiliary handle(s). Loss of control can
cause personal injury.
•Brace the tool properly before use. This tool
produces a high output torque and without properly
bracing the tool before operation, loss of control may
occur resulting in personal injury.
•Hold the power tool by insulated gripping
surfaces, when performing an operation where
the cutting accessory or fasteners may contact
hidden wiring. Cutting accessory or fasteners
contacting a “live” wire may make exposed metal
parts of the power tool “live” and could give the
operator an electric shock.
Safety instructions when using long drill bits
•Never operate at higher speed than the maximum
speed rating of the drill bit. At higher speeds, the
bit is likely to bend if allowed to rotate freely without
contacting the workpiece, resulting in personal injury.
• Always start drilling at low speed and with the
bit tip in contact with the workpiece. At higher
speeds, the bit is likely to bend if allowed to rotate
freely without contacting the workpiece, resulting in
personal injury.
• Apply pressure only in direct line with the bit
and do not apply excessive pressure. Bits can
bend causing breakage or loss of control, resulting
in personal injury.
SPECIFIC SAFETY RULES FOR
CORE STANDS
Diamond drill safety warnings
•When performing drilling that requires the use of
water, route the water away from the operator’s
work area or use a liquid collection device. Such
precautionary measures keep the operator’s work
area dry and reduce the risk of electrical 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 hearing protection when diamond drilling.
Exposure to noise can cause hearing loss.
•When the bit is jammed, stop applying down-
ward pressure and turn o the tool. Investigate
and take corrective actions to eliminate the cause
of the bit jamming.
•When restarting a diamond drill in the workpiece
check that the 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, at or well
axed, the pad may pull away from the workpiece.
•Ensure there is sucient vacuum before and
during drilling. If the vacuum is insucient, the
pad may release from the workpiece.
•Never perform drilling with the machine secured
by the vacuum pad only, except when drilling
downwards. 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.
•Do not use this tool for overhead drilling with
water supply. Water entering the power tool will
increase the risk of electric shock.
ADDITIONAL SPECIFIC
SAFETY RULES
•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 and batteries for dam-
age. Have damaged parts repaired or replaced by
a MILWAUKEE service facility.
•
To reduce the risk of injury, when
working in dusty situations, wear
appropriate respiratory protection or use an
OSHA compliant dust extraction solution.
• Always use common sense and be cautious when
using tools. It is not possible to anticipate every
situation that could result in a dangerous outcome.
Do not use this tool if you do not understand these
operating instructions or you feel the work is beyond
your capability; contact Milwaukee Tool or a trained
professional for additional information or training.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing,
contact a MILWAUKEE service facility for a free
replacement.
