GENERAL POWER TOOL SAFETY WARNINGS

RYOBI Cut-Off Tool User Manual  & troubleshooting 3 WARNING :  Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.
The term “power tool” in the warnings refers to your mains operated (corded) power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY

  • Keep work area clean and well lit. Cluttered or dark areas invite accidents.
  • Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
  • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

  • Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs an  matching outlets will reduce risk of electric shock.
  • Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators.There is an increased risk of electric shock if your body is earthed or grounded.
  • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
  • Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
  • When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
  • If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk
    of electric shock.Use this product only with batteries and chargers listed
    in tool/appliance/battery pack/charger correlation supplement 987000-432.

PERSONAL SAFETY

  • Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
  • Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
  • Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.
  • Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
  • Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
  • Dress properly. Do not wear loose clothing or jewellery. Keep your hair,  clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
  • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection
    can reduce dust-related hazards.
  • Do not let familiarity gained from frequent use of tool sallow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
  • Do not wear loose clothing or jewelry. Contain long hair. Loose clothes, jewelry, or long hair can be drawn into air vents.
    Do not use on a ladder or unstable support. Stable footing on a solid surface enables better control of the power tool in unexpected situations.

POWER TOOL USE AND CARE

  • Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
  • Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
  • Disconnect the plug from the power source and/ or remove the battery pack, if detachable, from the power tool before making any adjustments, changing
    accessories, or storing power tools. Such preventive safety measures reduce the  risk of starting the power tool accidentally.
  • Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
  • Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the
    power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
  • Keep cutting tools sharp and clean. Properly maintained cutting tools with  sharp cutting edges are less likely to bind and are easier to control.
  • Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
  • Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

BATTERY TOOL USE AND CARE

  • Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
  • Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
  • When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
  • Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentall yoccurs, flush with water. If liquid contacts eyes,  additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
  • Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
  • Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265°F may cause explosion.
  • Follow all charging instructions and do not charge the battery pack or tool  outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

SERVICE

  • Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
  • Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

SAFETY INSTRUCTIONS FOR CUT-OFF TOOLS

  • The guard provided with the tool must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the operator. Position yourself and bystanders away from the plane of the rotating wheel. The guard helps to protect operator from broken wheel fragments and accidental contact with wheel.
  • Use only bonded reinforced or diamond cut-off wheels for your power tool. Just because an accessory canbe attached to your power tool, it does not  assure safe operation.
  • The rated speed of the accessory must be at least equal to the maximum speed  marked on the power tool. Accessories running faster than their rated speed can break and fly apart.
  • Wheels must be used only for recommended applications. For example: do not grind with the side of cut-off wheel. Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.
  • Always use undamaged wheel flanges that are of correct diameter for your selected wheel. Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage.
  • Do not use worn down reinforced wheels from larger power tools. Wheels intended for a larger power tool are not suitable for the higher speed of a smaller tool and may burst.
  • The outside diameter and the thickness of your accessory must be within the capacity rating of your power tool. Incorrectly sized accessories cannot be adequately guarded or controlled.
  • The arbour size of wheels and flanges must properly fit the spindle of the power tool. Wheels and flanges with arbour holes that do not match the  mounting hardware of the power tool will run out of balance, vibrate excessively and may cause loss of control.
  • Do not use damaged wheels. Before each use, inspect the wheels for chips and cracks. If power tool or wheel is dropped, inspect for damage or install an undamaged wheel. After inspecting and installing the wheel, position yourself  and bystanders away from the plane of the rotating wheel and run the power  tool at maximum no load speed for one minute. Damaged wheels will normally break apart during this test time.
  • Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and shop apron capable of stopping small abrasive or  workpiece fragments. The eye protection must be capable of stopping flying debris generated by various operations. The dust mask or respirator must be capable of filtrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.
  • Keep bystanders a safe distance away from work area. Anyone entering the work area must wear personal protective equipment. Fragments of workpiece or of a broken wheel may fly away and cause injury beyond immediate area of operation.
  • Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
  • Never lay the power tool down until the accessory has come to a complete stop. The spinning wheel may grab the surface and pull the power tool out of your control.
  • Do not run the power tool while carrying it at your side. Accidental contact  with the spinning accessory could snag your clothing, pulling the accessory into your body.
  • Regularly clean the power tool’s air vents. The motor’s fan will draw the dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
  • Do not operate the power tool near flammable materials. Sparks could ignite  these materials.

KICKBACK AND RELATED WARNINGS:

Kickback is a sudden reaction to a pinched or snagged rotating wheel. Pinching or snagging causes rapid stalling of the rotating wheel which in turn causes the uncontrolled power tool to be forced in the direction opposite of the wheel’s rotation at the point of the binding. For example, if an abrasive wheel is snagged or pinched by the workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. The wheel may either jump toward or away from the operator, depending on direction of the wheel’s movement at the point of pinching. Abrasive
wheels may also break under these conditions. Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

  • Maintain a firm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use auxiliary handle, if provided,for maximum control over kickback or torque reaction  during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.
  •  Never place your hand near the rotating accessory. Accessory may kickback over your hand.
  • Do not position your body in line with the rotating wheel. Kickback will propel the tool in direction opposite to the wheel’s movement at the point of snagging.
  • Use special care when working corners, sharp edges etc. Avoid bouncing and snagging the accessory. Corners, sharp edges or bouncing have a tendency to
    snag the rotating accessory and cause loss of control or kick back.
  • Do not attach a saw chain, woodcarving blade, segmented diamond wheel with a peripheral gap greater than 10 mm or toothed saw blade. Such blades create frequent kickback and loss of control.
  • Do not “jam” the wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut. Over stressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback or wheel breakage.
  • When wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a
    complete stop. Never attempt to remove the wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding.
  • Do not restart the cutting operation in the workpiece. Let the wheel reach full speed and carefully re-enter the cut. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece.
  • Support panels or any over sized workpiece to minimize the risk of wheel pinching and kickback. Large workpieces tend to sag under their own weight. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel.
  • Use extra caution when making a “pocket cut” into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback.
  • Operations such as grinding, sanding, wire brushing, or polishing are not recommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.

ADDITIONAL SAFETY RULES

  • Know your power tool. Read operator’s manual carefully. Learn its applications and limitations, as well as the specific potential hazards related to this tool. Following this rule will reduce the risk of electric shock, fire, or serious injury.
  •  Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.

  • Rotate the guard until it snaps securely into one of the four fixed positions.

KICKBACK
See Figures 8 – 9, page 14.

Kickback occurs when the wheel stalls rapidly and the tool is driven back towards you. Wheel stalling is caused by any action which pinches the wheel in the material.

RYOBI Cut-Off Tool User Manual  & troubleshooting 26 DANGER:
Release switch immediately if wheel binds or tool stalls. Kickback could cause you to lose control of the tool. Loss of control can lead to serious personal injury.

To guard against kickback, avoid dangerous practices such as the following:

  • Twisting the cutting wheel while making a cut.
  • Making a cut with a dull, gummed up, or improperly set cutting wheel.
  • Forcing a cut.
  • Operating the tool incorrectly or misusing the tool.

To lessen the chance of kickback, follow these safety practices:

  •  When appropriate, adjust the shoe assembly up or down to set the depth of cut. The shoe assembly should be positioned so that very little of the cutting wheel is visible below the workpiece. The more wheel is exposed, the more  likely the tool is to bind and kickback.
  • Make straight cuts. Always use the shoe assembly or a straight edge guide when  rip cutting. This helps prevent twisting the wheel.
  • Support and clamp the workpiece properly before beginning a cut.
  • Use steady, even pressure when making a cut. Never force a cut.
  • Always let the cutting wheel reach full speed before beginning a cut.
  • Hold the tool firmly and keep your body in a balanced position so as to resist the forces if kickback should occur.
    WARNING:
    When using the tool, always stay alert and exercise control. Do not remove the tool from the workpiece while the cutting wheel is moving.

OPERATING THE TOOL
See Figures 10 – 12, page 14.

RYOBI Cut-Off Tool User Manual  & troubleshooting 27 DANGER:
Never use the tool with the guard removed. It has been designed for use only with the guard installed. Attempting to use tool with guard removed will result in loose particles being thrown against the operator resulting in serious personal injury.

RYOBI Cut-Off Tool User Manual  & troubleshooting 28 WARNING:
To make cutting easier and safer, always maintain proper control of the tool. Loss of control could cause an accident resulting in possible serious injury.

RYOBI Cut-Off Tool User Manual  & troubleshooting 29 WARNING:
When lifting the tool from the workpiece, the wheel is exposed on the underside of the tool.

  • Remove the battery pack.
  • Install the appropriate cutting wheel and rotate the wheel guard to the desired position.
  • Adjust the shoe assembly up or down to set the depth of cut or remove it  completely if needed.
  • Secure the workpiece to a work bench or table with a vise or with clamps.
  • Mark the line of cut clearly.
  • Install the battery pack.
  • Check the direction of rotation on the wheel and select the correct setting (forward or reverse) on the tool.
  • Hold the tool firmly in front of and clearly away from you, keeping the cutting wheel clear of the workpiece.
  • Depress the switch trigger and let the cutting wheel reach full speed.
    WARNING:
    The wheel coming in contact with the workpiece before it reaches full speed could cause tool to “kickback” toward you resulting in serious injury.
  • Move the wheel through the workpiece.
    NOTE: Do not force. Use only enough pressure to keep the tool cutting. Let the wheel and tool do the work.
  • Continue to use steady and even pressure to obtain a uniform cut through the material. Never force the wheel into the material being cut.
  • When the cut is complete, release the switch trigger and allow the wheel to stop rotating before raising the wheel out of material.

CUTTING TILES

Always draw the line to be cut on the tile using a marker or grease pencil. If the tile is shiny and hard-to-mark, place masking tape on the tile and mark the tape.

A common problem when cutting tile is straying from the marked line. Once you’ve strayed from the mark, you can not force the wheel back to the line by twisting the tile. Instead, back up and recut the tile slicing off a small amount of tile until the wheel is back on track.

CUTTING PLASTICS

Heat generated from the cutting wheel can melt plastic. Follow these steps to reduce the risk of overheating the cutting wheel:

  • Cut slowly and do not force the wheel into the material. Maintain a speed and pressure which allows cutting without overheating the wheel.
  • Take frequent breaks when cutting plastic materials and allow the cutting wheel to cool.

CUTTING METALS

With a metal cutting wheel installed, you may cut metals such as sheet steel, pipe, steel rods, aluminum, brass, and copper. Use caution when cutting metals and observe the following to avoid potential hazards:

  • Adjust the position of the wheel guard to provide maximum protection from sparks and loose particles thrown from the cutting wheel.
  • Material will get hot during cutting operation. Keep hands off of metal being cut to avoid serious personal injury.
  • Do not touch the cut material until it cools or you can be burned.
