General Safety Rules
Warning! Read all instructions. Failure to follow all instructions listed below may result in
electric shock, fire and/or serious injury. The term "power tool" in all of the warnings listed below refers to your mains-operated (corded) power tool or battery-operated (cordless)
power tool. Save these instructions
Work area
• Keep work area clean and well lit. Cluttered and 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 and 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 residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
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 mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
• Avoid accidental starting. Ensure the switch is in the off-position before plugging in.
Carrying power tools with your finger on the switch or plugging in 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 jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewelry 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 these devices can reduce dustrelated hazards.
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 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.
• 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. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools 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 and in the manner intended for the particular type of power tool, 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.
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.
• Safety Warnings Common for Grinding:
• This power tool is intended to function as a grinder. 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.
• Operations such as sanding, wire brushing, polishing or cutting-off 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.
• Do not use accessories which 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.
• 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.
• 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 arbor size of wheels, flanges, backing pads or any other accessory must properly fit the spindle of the power tool. Accessories with arbor 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 a damaged accessory. Before each use inspect the accessory such as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess wear, wire brush for loose or cracked wires. If 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.
• Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop apron capable of stopping small abrasive or work piece 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 work piece or of a broken accessory may fly away and cause injury beyond immediate area of operation.
• Hold 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 shock the operator.
• 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.
• 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.
• 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.
• Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in electrocution or shock.
Further safety instructions for all operations:
• 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 the area where power tool will move if kickback occurs.
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 kickback.
• Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades create frequent kickback and loss of control.
Additional Safety Instructions for Angle Grinder
• Use only wheel (disc) 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.
• The guard must be securely attached to the power tool and positioned for
maximum safety, so the least amount of wheel (disc) is exposed towards the
operator. The guard helps to protect operator from broken wheel fragments and accidental contact with wheel.
• Wheels (discs) must be used only for recommended applications. For example:
do not grind with the side of a 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 (disc) flanges that are of 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.
• Do not use worn down wheels from larger power tools. Wheels intended for larger power tools are not suitable for the higher speed of a smaller tool and may burst.
• Make sure the wheel (disc) is not contacting the work piece before the tool is
turned on. Having the wheel resting on the work piece before starting the tool could result in the tool kicking as it grips the work piece, this could cause potential personal harm and/or material damage.
• Check the wheel (disc) carefully for cracks or damage before operation. Replace cracked or damaged wheels immediately.
• Before operation of the tool an actual work piece, let it run for a few moments.
Watch for vibration or wobbling that could indicate poor installation of the wheel (disc) or a poorly balanced wheel.
• Watch out for flying sparks. Hold the tool at an angle of approximately 15 - 30° to the work piece surface.
• Use only wheels (discs) having a maximum operating speed at least as high as
the “No load speed” marked on the rating label of this tool. Using a wheel with a lower maximum speed rating than the tool is dangerous and could result in the wheel breaking during use causing potential personal harm and/or material damage.
• It should never be necessary to force the tool. If rotational speed drops abnormally, the pressure should be released immediately. Little more than the weight of the tool should be applied. Applying (forcing) excessive pressure can cause dangerous wheel breakage or burn out of the tools motor.
Assembly/Adjustments
BE SURE TO DISCONNECT THE ANGLE GRINDER FROM THE POWER
SUPPLY BEFORE ATTACHING OR REMOVING A DISC OR ATTACHMENT.
Make sure the grinding or cutting disc is mounted with the label on top (facing the angle grinder). If you are fitting any other kind of attachment, refer to attachment fitting instructions. ATD Tools will not be responsible for any damage or injury caused due to the incorrect fitting of grinding or cutting discs or any other kind of attachment.
Incorrect attachments can cause the motor to burn out, generally damage the tool and/or cause injury.
Assembling the side handle
The side handle (5) can be fitted on either the left or the right hand side of your grinder.
Choose the most appropriate position considering user comfort (preferred hand) and the task at hand.
Attaching and removing the grinding disc
• Inspect the grinding disc (7) before fitting and during use to ensure it is not deformed or cracked.
• Do not fit or use a grinding disc (7) for cutting applications - For cutting, use a cutting disc and ask your hardware retailer for advice regarding the type of cutting disc you require for the material you wish to cut. Grinding discs are used for grinding metal only.
• The grinding disc (7) is not solid. It is made from grit which is bonded together with reinforcement and adhesives. It is always possible that a part of the disc can dislodge and fly away from the tool at high speed. This is why you must wear the appropriate safety equipment (glasses, gloves and protective clothing) described herein and follow all safety instructions also described herein.
• Do not use any kind of attachment (discs or otherwise) that has a diameter greater than

(9) supplied to loosen the outer flange (10).
• Never press the spindle lock button (2) when the disc or attachment is still rotating.
Always wait until the disc or attachment has stopped rotating before pressing the spindle lock button (2). Pressing the spindle lock button (2) will cause damage to the spindle lock mechanism which will not be covered under warranty.
• Holding the angle grinder with the spindle facing upwards, ensure the inner flange (11) is on the spindle and located correctly. The two machined flat sections on one side of the inner flange (11) must face the angle grinder and locate in the appropriate position on the spindle.
• Insert the hole in the grinding disc (7) over the angle grinder spindle with the disc label facing the angle grinder. The hole in the disc should be located onto the spindle.
Ensure the hole in the disc locates and fits firmly into the ring section of the inner flange
(11).
Operation
• Screw the outer flange (10) onto the spindle with the protruding ring section facing the angle grinder. This ring section must locate with the hole in the grinding disc (7).
• Tighten the outer flange (10) by locking the spindle (using the spindle lock button) and then tightening the outer flange (10) with the pin spanner (9) provided.
• Removal of the disc is conducted in reverse order to the above.
• Regularly check that the outer flange has not loosened during use.
Note: When fitting a cutting disc or diamond wheel, the ring section on the outer flange should face away from the disc / wheel in order for the face of the outer flange (10) to sit flush against the bottom side of the disc / wheel.
Note: Disc/wheel label or marking, should face towards inner flange.
On/off switch
The ON/OFF switch (4) is provided with a lock button (3). Simply pull the trigger then push in the button to lock the trigger in the ‘ON’ position. To unlock, pull the trigger a second time.
The lock button is used to aid in reducing fatigue in the hands and arms when operating the tool for lengthy periods.

Safety guard
The safety guard (6) is assembled to your tool for your protection. The safety guard (6) will protect you from any dislodging objects or materials that may be ejected by the cutting/grinding discs during normal operation. This guard (6) will protect you from any accidental contact of the disc with your hands, fingers and any other parts of your body.
To adjust the safety guard (6), first disconnect the tool from the power supply.
Now loosen the Allen key bolt by using the Allen key. Rotate the safety guard (6) into the required position, and then refasten the bolt. Ensure the safety guard (6) is firmly secured prior to use.
Basic abrasive cutting procedure
First ensure the work piece is securely held down (by both sides of the work piece if possible). Turn on the angle grinder and proceed to start the cut gently - do not
“bump” the cutting disc to start a cut. Feed the disc through the work as fast as possible without slowing the cutting disc in the cut or laboring the machine. The abrasive cutting operation generates a great deal of localized heat which causes rapid expansion of the piece being cut. Discs operated at speeds significantly below the efficient speed or if fed through the cut too slowly will generate
excessive heat. Such heat can cause rapid disc wear, fraying around the edge of the reinforced discs and disc breakage.
Basic grinding procedure
First ensure the work piece is securely held down (by both sides of the work piece if possible). Turn on the angle grinder and proceed to start grinding your work piece gently - do not “bump” the grinding disc on your work piece as this may damage your grinding disc. The optimal grinding position is to hold your grinder at approximately 10-15º to your work piece and grind slowly. This will assist you and prevent deep gouging.
Maintenance
• Keep ventilation slots of the grinder clean at all times and prevent any foreign matter
from entering.
• If the enclosure of the grinder requires cleaning do not use solvents but a moist soft
cloth only.
• The grease in the gearbox will require replacement / replenishment after extensive use of
the grinder. Please see a qualified electrical repairer to provide this service.
• Blow out the unit through the rear ventilation slots with compressed air periodically to
ensure a dust free area around the switch.
• Carbon brushes should be replaced before they wear out. Both carbon brushes should
be replaced at the same time.
• Sparking visible through the housing air vents. A small amount of sparking may be
visible through the housing vents. This is normal and does not indicate a problem.
• Excessive sparking visible through the housing air vents and/or the tool FAILING
to operate May indicate the carbon brushes have worn down and need to be replaced.
Carbon brushes should only be replaced by a qualified electrician or power tool repairer.
