RULES FOR SAFE OPERATION
READ ALL INSTRUCTIONS
KNOW YOUR POWER TOOL. Read the
operator's manual carefully. Learn the saw's applications and limitations as well as the 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 good working order.
REMOVE ADJUSTING KEYS AND WRENCHES. Get in the habit of checking to see
that hex keys and adjusting wrenches are removed from tool before turning on saw.
KEEP THE WORK AREA CLEAN. Cluttered work areas and work benches invite accidents. DO NOT leave tools or pieces of wood on the saw 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 lit.
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 while operating.
MAKE WORKSHOP CHILD-PROOF 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. Do not force the tool or attachment to do a job it was not designed for. Don't use it for a purpose not intended.
USE THE PROPER EXTENSION CORD FOR CHARGER. 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.
PERIODICALLY INSPECT EXTENSION CORDS and replace if damaged.
DRESS PROPERLY. Do not wear loose clothing,
gloves, neckties, rings, bracelets, or other jewelry. They can get caught and draw you into moving parts. Rubber gloves and nonslip footwear are recommended when working outdoors. Also 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.
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.
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 better and safer 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 or battery pack removed.
AVOID ACCIDENTAL STARTING. Be sure switch is in the locked or off position before inserting battery pack. Carrying tools with your finger on the switch or inserting the battery pack into a tool with the switch on invites accidents.
USE RECOMMENDED ACCESSORIES. The use of improper accessories may cause risk of injury. Refer to this operator's manual for recommended accessories.
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.

RULES FOR SAFE OPERATION
NEVER LEAVE TOOL RUNNING UNAT­TENDED. REMOVE BATTERY PACK. Do not
leave tool, move workpiece or make adjustments until it comes to a complete stop.
FIRMLY CLAMP OR BOLT your miter saw to a workbench or table at approximately hip height.
USE ONLY CORRECT BLADES. Do not use blades with incorrect size holes. Never use blade washers or blade bolts that are defective or incorrect. The maximum blade capacity of your saw is 8-1/4 in. (209.6 mm).
KEEP BLADES CLEAN, SHARP AND WITH SUFFICIENT SET. Sharp blades minimize
stalling and kickback.
DO NOT REMOVE THE SAW'S BLADE GUARDS. Never operate the saw with any guard
or cover removed. Make sure all guards are operating properly before each use.
KEEP HANDS AWAY FROM CUTTING AREA.
Keep hands away from blades. Do not reach underneath work or around or under the blade while blade is rotating. Do not attempt to remove cut material when blade is moving.
BLADE COASTS AFTER TURN OFF.
DO NOT ABUSE CHARGER CORD. Never yank
cord to disconnect it from receptacle. Keep cord from heat, oil, and sharp edges.
INSPECT CHARGER CORD PERIODICALLY
and if damaged, have repaired at your nearest authorized service center.
DO NOT USE TOOL IF SWITCH DOES NOT TURN IT ON AND OFF. Have defective switches
replaced by an authorized service center.
KEEP TOOL DRY, 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.
ALWAYS SUPPORT LONG WORKPIECES to minimize risk of blade pinching and kickback. Saw may slip, walk, or slide while cutting long or heavy boards.
BEFORE MAKING A CUT, BE SURE ALL ADJUSTMENTS ARE SECURE.
AVOID CUTTING NAILS. Inspect for and remove all nails from lumber before cutting.
ALWAYS USE A CLAMP to secure the work- piece when possible.
NEVER TOUCH BLADE or other moving parts during use.
NEVER START A TOOL WHEN THE BLADE IS IN CONTACT WITH WORKPIECE. Allow motor to come up to full speed before starting cut.
MAKE SURE THE MITER TABLE AND SAW ARM (BEVEL FUNCTION) ARE LOCKED IN POSITION BEFORE OPERATING YOUR SAW.
Lock the miter table by securely tightening the miter lock handle. Lock the saw arm (bevel function) by securely tightening the bevel lock knob.
NEVER USE A LENGTH STOP ON THE FREE SCRAP END OF A CLAMPED WORKPIECE. NEVER hold onto or bind the free scrap end of
the workpiece in any operation. If a work clamp and length stop are used together, they must both be installed on the same side of the saw table to prevent the saw from catching the loose end and kicking up.
NEVER cut more than one piece at a time. DO NOT STACK more than one workpiece on the
saw table at a time.
NEVER PERFORM ANY OPERATION "FREE­HAND". Always place the workpiece to be cut on
the miter table and position it firmly against and parallel to the fence as a backstop. Always use the fence.
NEVER hand hold a workpiece that is too small to be clamped. Keep hands clear of the no hands zone.
NEVER reach behind, under, or within three inches (76 mm) of the blade and its cutting path with your hands and fingers for any reason.
NEVER reach to pick up a workpiece, a piece of scrap, or anything else that is in or near the cutting path of the blade.
AVOID AWKWARD OPERATIONS AND HAND POSITIONS where a sudden slip could cause
your hand to move into the blade. ALWAYS make sure you have good balance. NEVER operate your miter saw on the floor or in a crouched position.
NEVER stand or have any part of your body in line with the path of the saw blade.
ALWAYS release the power switch and allow the saw blade to stop rotating before raising it out of the workpiece.
DO NOT TURN THE MOTOR SWITCH ON AND OFF RAPIDLY. This could cause the saw blade
to loosen and could create a hazard. Should this ever occur, stand clear and allow the saw blade to come to a complete stop. Disconnect your saw from the power supply and securely retighten the blade bolt.

RULES FOR SAFE OPERATION
REPLACEMENT PARTS. All repairs, whether
electrical or mechanical, should be made at your nearest authorized service center.
When servicing use only identical Ryobi replace­ment parts. Use of any other parts may create a hazard or cause product damage.
NEVER USE IN AN EXPLOSIVE ATMO­SPHERE. Normal sparking of the motor could
ignite fumes.
NEVER leave the miter saw unattended while connected to a power source.
POLARIZED PLUGS. To reduce the risk of electric shock, this charger has a polarized plug (one blade is wider than the other). This charger plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
IF ANY PART OF THIS MITER SAW IS MISS­ING or should break, bend, or fail in any way, or
should any electrical component fail to perform properly, release switch trigger, remove the battery pack and have damaged, missing, or failed parts replaced before resuming operation.
DO NOT OPERATE THIS TOOL WHILE UN­DER THE INFLUENCE OF DRUGS, ALCOHOL, OR ANY MEDICATION.
ALWAYS STAY ALERT! Do not allow familiarity (gained from frequent use of your saw) to cause a careless mistake. ALWAYS REMEMBER that a careless fraction of a second is sufficient to inflict severe injury.
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 THE WORK AREA HAS AMPLE LIGHTING to see the work and that no obstruc-
tions will interfere with safe operation BEFORE performing any work using your saw.
IMPORTANT SAFETY RULES FOR BATTERY TOOLS
Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in operating condition. Be aware of possible hazards when not using your battery tool or when changing accessories.
Remove battery pack from tool or make sure the switch is in the lock-off position before making any adjustments, changing accessories, storing the tool or when not in use. Such preventive safety measures reduce
the risk of starting the tool accidentally.
When battery pack is not in use, keep it away from metal objects like paper clips, coins, keys, nails, screws, other small metal objects as well as necklaces, chains, rings etc. that can make a connection from one terminal to another. Shorting the battery terminals together
may cause sparks, burns, or a fire.
Use battery operated tool only with specifically designated battery pack. Use of
any other batteries may create a risk of fire. Use only the battery pack listed.
USE ONLY THE CHARGER PROVIDED WITH YOUR BATTERY TOOL. Do not substitute any
other charger. Use of another charger could cause batteries to explode causing possible serious injury.
DO NOT PLACE BATTERY TOOLS OR THEIR BATTERIES NEAR FIRE OR HEAT. Batteries
vent hydrogen gas and can explode in the presence of heat or a source of ignition, such as a pilot light. To reduce the risk of serious personal injury, never use any cordless product in the presence of open flame. An exploded battery can propel debris and chemicals. If exposed, wash immediately with soap and water and neutralize with lemon juice or vinegar.
DO NOT CHARGE BATTERY TOOL IN A DAMP OR WET LOCATION.
Your battery tool should be charged in a location where the temperature is more than 50°F (10°C) but less than 100°F (37°C).
Under extreme usage or temperature conditions, battery leakage may occur. If liquid comes in contact with your skin, wash immediately with soap and water, then neutralize with lemon juice or vinegar. If liquid gets in your eyes, flush them with clean water for at least 10 minutes, then seek immediate medical attention.
If carrying your battery tool at your side, make sure it is not running and your finger is not on the switch. Avoid accidental starting.
WHEN SERVICING USE ONLY IDENTICAL RYOBI REPLACEMENT PARTS.
