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 band saw works.
READ ALL INSTRUCTIONS
■ KNOW YOUR POWER TOOL. Read the operator's
manual carefully. Learn the applications and limitations
as well as specific potential hazards related to this tool.
■ GUARD AGAINST ELECTRICAL SHOCK by preventing
body contact with grounded surfaces. For example: pipes,
radiators, ranges, refrigerator enclosures.
■ KEEP GUARDS IN PLACE and in working order . Never
operate the tool with any guard or cover removed. Make
sure all guards are operating properly before each use.
■ REMOVE ADJUSTING KEYS AND WRENCHES. Form
habit of checking to see keys and adjusting wrenches
are removed from tool before turning it on.
■ KEEP THE WORK AREA CLEAN. Cluttered work areas
and work benches invite accidents.
■ DON’T 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
work area well lighted.
■ KEEP CHILDREN AND VISITORS AWAY. All visitors
should wear safety glasses and be kept a safe distance
from work area.
■ MAKE WORKSHOP CHILDPROOF with padlocks,
master switches, or by removing starter keys.
■ DON’T FORCE THE TOOL. It will do the job better and
safer at the rate for which it was designed.
■ USE THE RIGHT TOOL. Do not force the tool or
attachment to do a job for which it was not designed.
■ USE THE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one 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.
■ WEAR PROPER APP AREL. Do not wear loose clothing,
neckties, or jewelry that can get caught in the tool’s
moving parts and cause personal injury . Nonslip footwear
is recommended when working outdoors. Wear protective
hair covering to contain long hair.
■ ALWAYS WEAR SAFETY GLASSES WITH SIDE
SHIELDS. Everyday eyeglasses have only impact-
resistant lenses; they are NOT safety glasses.
■ SECURE WORK. Use clamps or a vise to hold work when
practical. It’s safer than using your hand and it frees both
hands to operate tool.
■ DO NOT OVERREACH. Keep proper footing and balance
at all times.
■ MAINTAIN TOOLS WITH CARE. Keep tools sharp and
clean for best and safest performance. Follow instructions
for lubricating and changing accessories.
■ DISCONNECT ALL TOOLS. When not in use, before
servicing, or when changing attachments, blades, bits,
cutters, etc., all tools should be disconnected from power
source.
■ REDUCE THE RISK OF UNINTENTIONAL ST ARTING.
Be sure switch is off when plugging in.
■ USE RECOMMENDED ACCESSORIES. Consult the
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 blade is unintentionally contacted.
■ CHECK DAMAGED PARTS. Before further use of 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 its
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.
■ DIRECTION OF FEED. Feed work into a blade or cutter
against the direction or rotation of the blade or cutter only .
■ NEVER LEAVE TOOL RUNNING UNATTENDED.
TURN POWER OFF. Don’t leave tool until it comes to a
complete stop.
■ DON’T ABUSE CORD. Never carry tool by the cord or
yank it to disconnect from receptacle. Keep cord from
heat, oil, and sharp edges.
■ PROTECT YOUR LUNGS. Wear a face or dust mask if
the cutting operation is dusty.
■ PROTECT YOUR HEARING. Wear hearing protection
during extended periods of operation.
WARNING: Blade coasts after turn off.
■ KEEP TOOL DR Y, CLEAN, AND FREE FROM OIL AND
GREASE. Always use a clean cloth when cleaning. Never
use brake fluids, gasoline, petroleum-based products, or
any solvents to clean tool.
■ INSPECT TOOL CORDS AND EXTENSION CORDS
PERIODICALLY and, if damaged, have repaired by a
qualified service technician. Stay constantly aware of cord
location and keep it well away from the rotating wheel.
■ NEVER USE IN AN EXPLOSIVE ATMOSPHERE.
Normal sparking of the motor could ignite fumes.
■ USE ONLY OUTDOOR EXTENSION CORDS with
approved ground connection that are intended for use
outdoors and so marked.
■ BE SURE THE BLADE PATH IS FREE OF NAILS.
Inspect for and remove nails from lumber before cutting.

RULES FOR SAFE OPERATION
■ AVOID AWKWARD OPERATIONS AND HAND POSI-
TIONS where a sudden slip could cause your hand to
move into the blade. ALWAYS make sure you have good
balance.
■ ALLOW THE MOTOR TO COME UP TO FULL SPEED
before starting a cut to avoid binding or stalling.
■ DO NOT USE TOOL IF SWITCH DOES NOT TURN IT
ON AND OFF. Have defective switches replaced by an
authorized service center.
■ REPLACEMENT PARTS. All repairs, whether electrical
or mechanical, should be made by a qualified service
technician at an authorized service center.
WARNING:
When servicing use only identical Ryobi replacement
parts. Use of any other parts may create a hazard or
cause product damage.
■ KEEP HANDS AW AY FROM CUTTING AREA. Do not
hand hold pieces so small that your fingers go under
the blade guard. Do not reach underneath work or in
blade cutting path with your hands and fingers for any
reason.
■ NEVER CUT MORE THAN ONE PIECE AT A TIME or
stack more than one workpiece on the saw table at a
time.
■ FIRMLY CLAMP OR BOLT your saw to a stable, level
workbench or table. The most comfortable table height
is approximately waist height.
■ DO NOT FEED THE MA TERIAL T OO QUICKLY. Do not
force the workpiece against the blade.
■ USE ONLY CORRECT BLADES. Use the right blade
size, style and cutting speed for the material and the type
of cut. Blade teeth should point down toward the table.
■ BEFORE MAKING A CUT, BE SURE ALL ADJUST-
MENTS ARE SECURE.
■ ALWAYS SUPPORT LARGE WORKPIECES while cut-
ting to minimize risk of blade pinching and kickback. Saw
may slip, walk or slide while cutting large or heavy boards.
■ DO NOT REMOVE JAMMED CUTOFF PIECES until
blade has stopped.
■ NEVER ST ART THE TOOL when the blade is in contact
with the workpiece.
■ NEVER TOUCH BLADE or other moving parts during
use.
■ BEFORE CHANGING THE SETUP, REMOVING COVERS, GUARDS OR BLADES, unplug the saw
and remove the switch key.
■ KEEP BLADES CLEAN, SHARP, AND WITH SUFFICIENT SET. Sharp blades minimize stalling and kick-
backs.
■ ALWAYS TURN OFF SAW before disconnecting it to
avoid accidental starting when reconnecting to a power
source.
■ DO NOT OPERATE THIS TOOL WHILE UNDER THE
INFLUENCE OF DRUGS, ALCOHOL OR ANY
MEDICATION.
■ STAY ALERT AND EXERCISE CONTROL. Watch what
you are doing and use common sense. Do not operate
tool when you are tired. Do not rush.
■ MAKE SURE WORK AREA HAS AMPLE LIGHTING to
see the work and that no obstructions will interfere with
safe operation BEFORE performing any work using your
saw.
■ SA VE THESE INSTRUCTIONS. Refer to them frequently
and use them to instruct other users. If you loan someone
this tool, loan them these instructions also.
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.
SAVE THESE INSTRUCTIONS
ATTENTION:
WARNING:
The blade guides have been preset at the factory. These settings are functional for some applications. We recommend
that you check and adjust blade guide settings before first use of your saw. Refer to “ADJUSTING THRUST BEAR-
INGS, BLADE GUIDE SUPPORT, AND BLADE GUIDES” procedures explained in the
operator’s manual.

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 25 feet 16
26-50 feet 16
51-100 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.

ELECTRICAL CONNECTION
Your band saw is powered by a precision built electric motor.
It should be connected to a power supply that is 120 volts,
60Hz, AC only (normal household current). Do not operate this tool on direct current (DC). A substantial voltage drop
will cause a loss of power and the motor will overheat. If the
machine does not operate when plugged into an outlet,
double check the power supply.
CAUTION:
Keep the cord away from the cutting area and position
the cord so that it will not be caught on materials, tools,
or other objects during cutting.
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.
