Electrical Requirements And Safety - KNOVA KN DP-2000N Manual

IMPORTANT SAFETY INSTRUCTION FOR DRILL PRESS
• Do not operate the laser around children or allow children
to operate the laser / power tool.
• Do not disassemble. Modifying the product in any way
can increase the risk of laser radiation. Use of controls or
adjustments or performance of procedures other than
those specified in this manual may result in hazardous
laser radiation exposure.
• Do not operate in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust.
• Store idle product out of reach of children and other
untrained persons. Lasers / power tools are dangerous
in the hands of untrained users.
• Use only accessories that are recommended by the
manufacturer for your model. Accessories that may be
suitable for one laser / power tool, may create a risk of
injury when used on another laser / power tool.
• Repairs and servicing MUST be performed by a qualified
repair facility. Repairs performed by unqualified
personnel could result in serious injury.
• Do not remove or deface warning labels. Removing labels
increases the risk of exposure to radiation.

ELECTRICAL REQUIREMENTS AND SAFETY

POWER SUPPLY AND MOTOR SPECIFICATIONS
WARNING
To avoid electrical hazards, fire hazards, or damage
to the tool, use proper circuit protection. Use a
seperate electrical circuit for your tool. Your drill
press is wired at the factory for 120 V operation.
Connect to a 120 V, 2.3 Amp circuit and use a
2.3 Amp time delay fuse or circuit breaker. To avoid
shock or fire, if power cord is worn, cut, or damaged
in any way, have it replaced immediately.
GROUNDING INSTRUCTIONS
WARNING
This tool must be grounded while in use to protect the
operator from electrical shock.
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN,
grounding provides a path of least resistance for electric
currents and reduces the risk of electric shock. This tool
is equipped with an electrical cord that has an
equipment-grounding conductor and a grounding plug. The
plug must be plugged into a matching receptacle that is
properly installed and grounded in accordance with all local
codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED.
If it will not fit the receptacle, have the proper receptacle
installed by a qualified electrician.
IMPROPER CONNECTION of the equipment grounding
conductor can result in risk of electric shock. The conductor
with the green insulation (with or without yellow stripes) is
the equipment grounding conductor. If repair or replacement
of the electrical cord or plug is necessary, do not connect the
equipment grounding conductor to a live terminal.
CHECK with a qualified electrician or service person if you
do not completely understand the grounding instructions, or if
you are not certain the tool is properly grounded.
USE only 3-wire extension cords that have three-pronged
grounding plugs with three- pole receptacles that accept
the tool's plug. Repair or replace damaged or worn cords
immediately.
• For indoor use only.
• This product is intended for use in a temperature range
of 41°F (5°C) - 104°F (40°C).
WARNING
LASER RADIATION. AVOID DIRECT EYE
EXPOSURE. Do not stare into the laser light source.
Never aim light at another person or object other than
the work piece. Laser light can damage your eyes.
WARNING
LASER RADIATION. Never aim the beam at a work
piece with a reflective surface. Bright shiny reflective
sheet steel or similar reflective surfaces are not
recommended for laser use. Reflective surfaces could
direct the beam back toward the operator.
WARNING
DO NOT use tinted glasses to enhance the laser light.
Tinted glasses will reduce overall vision for the
application and interfere with the normal operation of
the tool.
Use a separate electrical circuit for your tool. This circuit must
not be less than #18 wire and should be protected with a
2.3 Amp time lag fuse. Before connecting the motor to the
power line, make sure the switch is in the off position and the
electric current is rated the same as the current stamped on
the motor nameplate. Running at a lower voltage will damage
the motor.
GUIDELINES FOR EXTENSION CORDS USE THE
PROPER EXTENSION CORD.
Make sure your extension cord is in good condition. Use an
extension cord heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line
voltage resulting in loss of power, overheating and burning
out of the motor. The table below shows the correct size to
use depending on cord length and nameplate ampere rating.
If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
Make sure your extension cord is properly wired and in good
condition. Always replace a damaged extension cord or have
it repaired by a qualified technician before using it. Protect
your extension cords from sharp objects, excessive heat and
damp or wet areas.
