RULES FOR SAFE OPERATION

Safe operation of this power tool requires that you read and
understand this operator's manual and all labels affixed to
the tool. Safety is a combination of common sense, staying
alert, and knowing how your tool works.

READ ALL INSTRUCTIONS

■ KNOW YOUR POWER TOOL. Safe operation of this

power tool requires that you read and understand this
operator’s manual and all labels affixed to the tool. Learn
its applications and limitations as well as the potential
hazards.

■ GUARD AGAINST ELECTRICAL SHOCK by preventing

body contact with grounded surfaces such as pipes,
radiators, ranges, refrigerator enclosures.

■ KEEP GUARDS IN PLACE and in good working order.

■ REMOVE ADJUSTING KEYS AND WRENCHES. Get in

the habit - before turning on tool - that hex keys and
adjusting wrenches are removed from tool.

■ KEEP THE WORK AREA CLEAN. Cluttered work areas
and work benches invite accidents. DO NOT leave tools
or pieces of wood on the machine while it is in operation.

■ DO NOT USE IN DANGEROUS ENVIRONMENTS. Do
not use power tools near gasoline or other flammable
liquids, in damp or wet locations, or expose them to rain.
Keep the work area well lighted.

■ KEEP CHILDREN AND VISITORS AWAY. All visitors
should wear safety glasses and be kept a safe distance
from work area. Do not let visitors contact tool or extension
cord while operating.

■ MAKE WORKSHOP CHILDPROOF with padlocks and
master switches or by removing starter keys.

■ DO NOT FORCE THE TOOL it will do the job better and
safer at the rate for which it was designed.

■ USE THE RIGHT TOOL FOR THE JOB. Do not force the
tool or attachment to do a job for which it was not designed
for. Use it only the way it was intended.

■ USE THE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. Use only a 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 and overheating. A wire gage size
(A.W.G.) of at least 16 is recommended for an extension
cord 25 feet or less in length. If in doubt, use the next
heavier gage. The smaller the gage number, the heavier
the cord.

■ DRESS PROPERLY. Do not wear loose clothing, gloves,
neckties, rings, bracelets, or other jewelry that could get
caught and draw you into moving parts. Non-slip footwear
is recommended. Wear protective covering over long hair.

■ ALWAYS WEAR SAFETY GLASSES WITH SIDE
SHIELDS. Everyday eyeglasses have only impact
resistant lenses; they are not safety glasses.

■ PROTECT YOUR LUNGS. Wear a face or dust mask if
the operation is dusty.

■ PROTECT YOUR HEARING. Wear hearing protection

during extended periods of operation.

■ SECURE WORK. Use clamps or a vise to hold the work

when practical. It’s safer than using your hand and frees
both hands to operate the tool.

■ DO NOT OVERREACH. Keep proper footing and balance

at all times.

■ MAINTAIN TOOLS WITH CARE. Keep tools sharp and

clean for better and safer performance. Follow instructions
for lubricating and changing accessories.

■ DISCONNECT ALL TOOLS. When not in use, before

servicing, or when changing attachments, all tools should
be disconnected.

■ AVOID ACCIDENTAL STARTING. Be sure switch is off

when plugging in any tool.

operator’s manual for recommended accessories. The
use of improper accessories may cause risk of injury.

■ NEVER STAND ON TOOL. Serious injury could occur if

the tool is tipped or if the bit is unintentionally contacted.

■ CHECK DAMAGED PARTS. Before using the tool, a

guard or other part that is damaged should be carefully
checked to determine that it will operate properly and
perform its intended function. Check for alignment of
moving parts, binding of moving parts, breakage of parts,
mounting and any other conditions that may affect
operation. A guard or other part that is damaged must be
properly repaired or replaced by an authorized service
center to avoid risk of personal injury.

■ NEVER LEAVE TOOL RUNNING UNATTENDED, TURN
THE POWER OFF. Do not leave tool until it comes to a

complete stop.

■ DO NOT ABUSE CORD. Never yank the cord to
disconnect it from the receptacle. Keep the cord from heat,
oil, and sharp edges.

■ KEEP BITS CLEAN AND SHARP. Sharp bits minimize
stalling. Dirty and dull bits may cause misalignment of
the material and possible operator injury.

■ KEEP HANDS AWAY FROM WORK AREA. Keep hands
away from the bit. Restrain any loose clothing, jewelry, long
hair, etc. that may become entangled in the bit.

■ KEEP TOOL DRY, CLEAN, AND FREE FROM OIL AND

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 paints,

• 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 specially designed to filter
out microscopic particles.

■ Never place your fingers in a position where they could
contact the drill or other cutting tool if the workpiece should
unexpectedly shift.

■ Never use your hand to hold the object while drilling.
Always clamp the object tight on the work table or use a
drill vise to prevent accidental injury.

■ Never perform any operation by moving the head or table
with respect to one another. Do not turn the motor switch
ON or start any operation before checking that the head
and table lock handles are clamped tight to column and
head and table support collars are correctly positioned.

■ Before engaging the power switch ON, make sure the
belt guard is down and the chuck is installed properly.

■ Lock the motor switch OFF when leaving the drill press.
Do not perform layout, assembly, or set-up work on the
table while the cutting tool is rotating, switched on or
connected to a power source.

■ Firmly clamp or bolt your drill press to a work bench or
table.

ELECTRICAL

EXTENSION CORDS

Use only 3-wire extension cords that have 3-prong ground­ing plugs and 3-pole receptacles that accept the tool's plug.
When using a power tool at a considerable distance from the
power source, use an extension cord heavy enough to carry
the current that the tool will draw. An undersized extension
cord will cause a drop in line voltage, resulting in a loss of
power and causing the motor to overheat. Use the chart
provided below to determine the minimum wire size required
in an extension cord. Only round jacketed cords listed by
Underwriter's Laboratories (UL) should be used.

Length of Extension Cord Wire Size (A.W.G.)

Up to 50 feet 16

When working with the tool outdoors, use an extension cord
that is designed for outside use. This is indicated by the
letters WA on the cord's jacket.

Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation. Repair or replace
a damaged or worn cord immediately.

CAUTION:

Keep the cord away from the cutting area and position
the cord so that it will not be caught on material, tools,
or other objects during cutting.

ELECTRICAL CONNECTION

Your Ryobi Drill Press is powered by a precision built electric
motor. It should be connected to a power supply that is 120
volts, 60Hz. If the machine does not operate when plugged
into an outlet, double check the power supply.

GROUNDING INSTRUCTIONS

In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped with an
electric cord having an equipment-grounding conductor and
a grounding plug. The plug must be plugged into a matching
outlet 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 outlet, have
the proper outlet installed by a qualified electrician. Improper
connection of the equipment-grounding conductor can result
in a risk of electric shock. The conductor with insulation
having an outer surface that is green with or without yellow
stripes is the equipment-grounding conductor. If repair or
replacement of the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a live
terminal.

Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if in
doubt as to whether the tool is properly grounded.

Repair or replace a damaged or worn cord immediately.

This tool is intended for use on a circuit that has an outlet like
the one shown in
one shown.
