DM15A9C/CDM2CSA — RULES FOR SAFE OPERATION
■
Maintain the core drill and drill bits with care. Make sure
bit maintains good diamond exposure. A dull bit will cause
glazing.
■
NEVER
drill into a work piece that is not secured.
■
Use this core drill only for its intended purpose.
DO NOT
use this core drill for applications not recommended.
■
Inspect the drill after each use. Replace any damaged or
worn parts immediately.
DO NOT
use a defective core-
drill.
■
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.
■
If a malfunction occurs, immediately unplug the core drill
from the power source and correct the problem. If the
problem can not be corrected, contact your nearest MQ
service center.
■
DO NOT
force your core drill. Excerting excessive force
while drilling will damage your machine and is hazardous.
■
ALWAYS
make sure drill bit is installed securely so that
it will not slip or fall out. It is hazardous to use a core drill
with a loose fitted drill bit.
■
Some materials contain chemicals which may be
toxic.Take precautions to prevent dust inhalation and skin
contact.
ELECTRICAL SAFETY
■
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
use a extension cord that is frayed or damaged
where the insulation has been cut.
■
NEVER
carry the core drill by its power cord or disconnect
it by yanking the cord from the power outlet.
■
ALWAYS
make certain that the proper extension cord
has been selected for the job. See Table 1.
■
NEVER
allow power cord to
lay in wate
r.
■
NEVER
stand in water
while operating the core drill.
■
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.
■
When plugging the core-drill into a power receptacle, check
the nameplate for the correct operating voltage. Operating
the core drill at the wrong voltage will damage the electric
motor.
ALWAYS
read the nameplate before applying
power.
■
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 fit into the receptacle, contact
a qualified electrician to install a 3-conductor wall
receptacle (outlet).
■
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.
■
DO NOT
expose the the core drill to rain or wet conditions.
Water entering the drill wii increase the risk of electrical
shock.
■
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.
■
ALWAYS
be on the lookout for hidden wiring, the
possibility exists of the drill bit making contact with hidden
wiring. Contact with a "live" wire can cause electrical
shock to the operator.
■
ALWAYS
remove the AC power cord from the power
source before performing any service or maintenance on
the core drill. This preventative safety measure reduces
the possibility of accidental starting.
