**GENERAL POWER TOOL SAFETY WARNINGS

**

WARNING
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions 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.

1. Work area safety
   a) Keep the work area clean and well-lit.
   Cluttered or dark areas invite accidents.
   b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
   Power tools create sparks that may ignite dust or fumes.
   c) Keep children and bystanders away while operating a power tool.
   Distractions can cause you to lose control.
2. Electrical safety
   a) 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 and matching outlets will reduce the risk of electric shock.
   b) 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.
   c) Do not expose power tools to rain or wet conditions.
   Water entering a power tool will increase the risk of electric shock.
   d) Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool.
   Keep the cord away from heat, oil, sharp edges, or moving parts.
   Damaged or entangled cords increase the risk of electric shock.
   e) When operating a power tool outdoors, use an extension cord suitable for outdoor use.
   The use of a cord suitable for outdoor use reduces the risk of electric shock.
   f) If operating a power tool in a damp location is unavoidable, use a residual
   current device (RCD) protected supply.
   The use of an RCD reduces the risk of electric shock.
3. Personal safety
   a) 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.
   b) Use personal protective equipment. Always wear eye protection.
   Protective equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.
   c) Prevent unintentional starting. Ensure the switch is in the off position before
   connecting to a power source and/or battery pack, picking up or carrying the tool.
   Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
   d) 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.
   e) Do not overreach. Keep proper footing and balance at all times.
   This enables better control of the power tool in unexpected situations.
   f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts.
   Loose clothes, jewelry, or long hair can be caught in moving parts.
   g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used.
   The use of dust collection can reduce dust-related hazards.
4. Power tool use and care
   a) 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.
   b) Do not use the power tool if the switch does not turn on and off.
   Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
   c) Disconnect the plug from the power source and/or the battery pack 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.
   d) 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.
   e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool operation.
   If damaged, have the power tool repaired before use.
   Many accidents are caused by poorly maintained power tools.
   f) Keep cutting tools sharp and clean.
   Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   g) 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.
5. Service
   a) 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.
   Keep children and infi rm persons away.
   When not in use, tools should be stored out of reach of children and infi rm persons.

SAFETY WARNINGS ARE COMMON FOR GRINDING OR ABRASIVE CUTTING-OFF OPERATIONS

a) This power tool is intended to function as a grinder or cut-off tool. 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.
b) Operations such as sanding, wire brushing, and 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.
c) Do not use accessories that are not specifically designed and recommended by the tool manufacturer.
Just because the accessory can be attached to your power tool, it does not assure safe operation.
d) 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 fl y apart.
e) 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.
f) Threaded mounting of accessories must match the grinder spindle thread. For accessories mounted by flanges, the arbor hole of the accessory must fi t the locating diameter of the flange.
Accessories that do not match the mounting hardware of the power tool will run out of balance, vibrate excessively, and may cause a loss of control.
g) Do not use a damaged accessory. Before each use inspects the accessory such as abrasive wheels for chips and cracks, a backing pad for cracks, tears, or excess wear, and a wire brush for loose or cracked wires. If a power tool or accessory is dropped, inspect for damage or install an undamaged accessory. After inspecting and installing an accessory, position yourself and bystanders away from the plane of the rotating accessory and run the power tool at maximum no-load speed for one minute.
Damaged accessories will normally break apart during this test time.
h) Wear personal protective equipment. Depending on the application, use a face shield, safety goggles, or safety glasses. As appropriate, wear a dust mask, hearing protectors, gloves, and a workshop 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.
i) Keep bystanders at a safe distance away from the work area. Anyone entering the work area must wear personal protective equipment.
Fragments of workpieces or of a broken accessory may fl y away and cause injury beyond the immediate area of operation.
j) Hold the power tool by insulated gripping surfaces only, when performing an operation where the cutting accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
k) Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
l) Never lay the power tool down until the accessory has come to a complete stop.
The spinning accessory may grab the surface and pull the power tool out of your control.
m) 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.
n) Regularly clean the power tool’s air vents.
The motor’s fan will draw dust inside the housing and excessive accumulation of powdered metal may cause electrical hazards.
o) Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
p) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in electrocution or shock.

KICKBACK AND RELATED WARNINGS

Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush, or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory’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 the 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.
a) Maintain a fi rm grip on the power tool and position your body and arm to allow you to resist kickback forces. Always use an 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.
b) Never place your hand near the rotating accessory.
The accessory may kick back over your hand.
c) Do not position your body in the area where the power tool will move if kickback occurs.
Kickback will propel the tool in the direction opposite to the wheel’s movement at the point of snagging.
d) 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 kickback.
e) Do not attach a saw chain woodcarving blade or toothed saw blade.
Such blades create frequent kickbacks and loss of control.

SAFETY WARNINGS SPECIFIC FOR GRINDING AND ABRASIVE CUTTING-OFF OPERATIONS

a) Use only wheel types that are recommended for your power tool and the specific guard designed for the selected wheel.
Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe.
b) The grinding surface of center depressed wheels must be mounted below the plane of the guard lip.
An improperly mounted wheel that projects through the plane of the guard lip cannot be adequately protected.
c) The guard must be securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed to the operator.
The guard helps to protect the operator from broken wheel fragments, accidental contact with the wheel, and sparks that could ignite clothing.
d) Wheels must be used only for recommended applications. For example: do not grind with the side of the cut-off wheel.
Abrasive cut-off wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.
e) Always use undamaged wheel flanges that are of the correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus reducing the possibility of wheel breakage.
Flanges for cut-off wheels may be different from grinding wheel flanges.
f) Do not use worn-down wheels from larger power tools.
The wheel intended for larger power tools is not suitable for the higher speed of a smaller tool and may burst.

ADDITIONAL SAFETY WARNINGS SPECIFIC FOR ABRASIVE CUTTING-OFF OPERATIONS

a) Do not “jam” the cut-off wheel or apply excessive pressure. Do not attempt to make an excessive depth of cut.
Overstressing 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.
b) Do not position your body in line with and behind the rotating wheel.
When the wheel, at the point of operation, is moving away from your body, the possible kickback may propel the spinning wheel and the power tool directly at you.
c) When the 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 cut-off 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.
d) 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 kick back if the power tool is restarted in the workpiece.
e) Support panels or any oversized 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.
f) 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.

GENERAL SAFETY INSTRUCTIONS FOR GRINDERS

• Check that speed marked on the wheel is equal to or greater than the rated speed of the grinder;
• Ensure that the wheel dimensions are compatible with the grinder;
• Abrasive wheels shall be stored and handled with care in accordance with the manufacturer’s instructions;
• Inspect the grinding wheel before use, do not use chipped, cracked, or otherwise defective products;
• Ensure that mounted wheels and points are fitted in accordance with the manufacturer’s instructions;
• Ensure that blotters are used when they are provided with the bonded abrasive product and when they are required;
• Ensure that the abrasive product is correctly mounted and tightened before use and run the tool at no-load for 30 seconds in a safe position, stop immediately if there is considerable vibration or if other defects are detected. If this condition occurs, check the machine to determine the cause;
• If a guard is equipped with the tool never use the tool without such a guard;
• When using an abrasive cutting wheel, be sure to remove With the standard accessory wheel guard and attach the wheel guard with the side guard (sold separately) (Fig. 1);
• Do not use separate reducing bushings or adapters to adapt large hole abrasive wheels;
• For tools intended to be fitted with a threaded hole wheel, ensure that the thread in the wheel is long enough to accept the spindle length;
• Check that the workpiece is properly supported;
• Do not use cutting off wheel for side grinding;
•  Ensure that sparks resulting from use do not create a hazard e.g. do not hit Fig. 1 persons, or ignite flammable substances;
• Ensure that ventilation openings are kept clear when working in dusty conditions, if it should become necessary to clear dust, first disconnect the tool from the mains supply (use nonmetallic objects) and avoid damaging internal parts;
• Always use eye and ear protection. Other personal protective equipment such as a dust mask, gloves, helmet, and apron should be worn;
• Pay attention to the wheel that continues to rotate after the tool is switched off.

ADDITIONAL SAFETY WARNINGS

1. Ensure that the power source to be utilized conforms to the power requirements specifi ed on the product nameplate.

2. Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

3. When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

   ○ Lubricate the sliding section of the set piece (B) and the lever if the lever does not move smoothly.

5. Ensure that mounted wheels and points are fitted in accordance with the manufacturer’s instructions.
   Ensure that the depressed center wheel to be utilized is the correct type and free of cracks or surface defects. Also ensure that the depressed center wheel is properly mounted and the wheel nut is securely tightened, Refer to the section on “ASSEMBLING AND DISASSEMBLING THE DEPRESSED CENTER WHEEL”.
   Ensure that blotters are used when they are provided with the bonded abrasive product and when they are required.
   Do not use separate reducing bushings or adaptors to adapt large-hole abrasive wheels.
   For tools intended to be fitted with a threaded hole wheel, ensure that the thread in the wheel is long enough to accept the spindle length.
   Do not use the cutting off wheel for side grinding.

6. Test the grinder before using it.
   Before actually beginning the grinding work, test the grinder by first clearing the area of all other personnel. Make sure the wheel guard is in place and that you are wearing eye protection. Turn the grinder “on”, and make sure the grinder runs smoothly and shows no abnormalities.
   The duration of the trial run is as follows:
   When the depressed center wheel is replaced ……………………………………..3 minutes or more
   When starting daily work ……………………………………………………………..1 minute or more

7. Check, the push button.
   Make sure that the push button is disengaged by pushing the push button two or three times before turning on the grinder. (Fig. 4)

8. Fixing the side handle

   Pull the switch lever to lock the off lock lever to the depressed position. Release the switch lever to automatically return the off lock lever to this original position. (Fig. 6)

2. Pressure
   To prolong the life of the machine and ensure a first class finish, it is important that the machine should not be overloaded by applying too much pressure. In most applications,
   the weight of the machine alone is sufficient for effective grinding. Too much pressure will result in reduced rotational speed, inferior surface finish, and overloading which could reduce the life of the machine.

3. Use proper grinding angle.
   Grind only with the wheel’s edge by lifting the grinder 15° to 30°, as shown in Fig. 7.
   CAUTION
   Do not use the entire surface of the depressed center wheel. Use only the edge of the depressed center wheel.

4. Move the grinder in the proper direction.
   When using a new depressed center wheel in direction A (Fig. 7), the wheel edge may be cut into the workpiece. In this case, grind in direction B (Fig. 7). Once the wheel edge is worn, the workpiece can be ground in both directions.

5. Precautions immediately after finishing operation
   The wheel continues to rotate after the tool is switched off.
   After switching off the machine, do not put it down until the depressed center wheel has come to a complete stop. Apart from avoiding serious accidents, this precaution will reduce the amount of dust and swarf sucked into the machine.

6. Hold the grinder firmly by its handle and side handle.
   The grinder produces a counterforce which must be controlled by firmly holding onto the grinder.

CAUTION

• Check that the workpiece is properly supported.

• Ensure that ventilation openings are kept clear when working in dusty conditions.
  If it should become necessary to clear dust, first disconnect the tool from the mains supply (use non-metallic objects) and avoid damaging internal parts.

• Ensure that sparks resulting from use do not create a hazard e.g. do not hit persons, or ignite flammable substances.

• Always use eye and ear protection.
  Other personal protective equipment such as a dust mask, gloves, helmet, and apron should be worn when necessary.
  If in doubt, wear protective equipment.

• When the machine is not used, the power source should be disconnected.
