SAFETY INFORMATION
ELECTRIC MOTOR SAFETY
CAUTION
When connecting the core drill to a power receptacle,
make sure the receptacle circuit is connected to either
a GFCI receptacle or a receptacle protected by a 20
amp circuit breaker.
This core drill is equipped with a 3-prong male power
plug.
DO NOT use a 2-prong adapter when plugging
into a wall outlet. This will defeat the purpose of the
ground circuit. If the plug does not fi t into the receptacle,
contact a qualifi ed electrician to install a 3-conductor wall
receptacle (outlet).
Operate electric motor only at the specifi ed voltage
indicated on the nameplate.
ALWAYS test the
ON/OFF
switch on the core drill before
operating. The purpose of this switch is to shut down the
electric motor.
NEVER cover the air vents on the body of the core drill.
ALWAYS leave these vents exposed. These vents are
essential for the cooling of the electric motor.
NEVER
place tape over the vent to keep out dust.
DO NOT spray water onto electric motor.
NEVER leave the core drill unattended. When not in use
always unplug the core drill from power source.
ALWAYS disconnect AC power plug from power source
before performing maintenance.
ALWAYS make sure the ON/OFF switch
on the electric motor is in the OFF position
when not in use.
ALWAYS hold core drill by its insulated
gripping handle when performing work. The possibility
exists of the drill bit making contact with hidden wiring
or its own cord. Contact with a "live" wire can cause
electrical shock to the operator.
DO NOT walk around with a plugged in core drill. The
possibility exist of your fi nger accidently hitting the power
ON/OFF switch, causing severe
bodily harm or even
death.
Avoid body contact with grounded surfaces such as
pipes, radiators, ranges and refrigerators. There is an
increased risk of electrical shock if your body is grounded.
When operating the core drill outside, be sure to use
the apporpriate outdoor extension cord. This type of
extension cord reduces the risk of electrical shock.
Power Cord/Cable Safety
DANGER
NEVER let power cords or cables lay in water.
NEVER
stand in water
while operating the core drill.
NEVER use damaged or worn cables or cords when
connecting equipment to generator. Inspect for cuts in
the insulation.
NEVER grab or touch a live power
cord or cable with wet hands. The
possibility exists of
electrical shock,
electrocution or death.
Make sure power cables are securely
connected. Incorrect connections may
cause electrical shock and damage to the
core drill.
CAUTION
Ensure that cables and cords will not be tripped over.
Never use the cable to pull out the plug from the power
source.
NOTICE
ALWAYS make certain that proper power or extension
cord has been selected for the job.
Protect the cable from heat, oil, and sharp edges.
TRANSPORTING
ALWAYS place the core drill inside its carrying case
when work has been completed.
ALWAYS wrap power cord neatly to avoid damage.
ALWAYS place wrenches back into carrying case when
work has been completed.
