Personal safety  
Safety instructions  
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.  
WARNING. Read and understand 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 below refers to your mains-operated (corded) power  
tool or battery-operated (cordless) power tool.  
Save these instructions  
Work area  
Use safety equipment. Always wear eye protection.  
Safety equipment such as a dust mask, non-skid  
safety shoes, hard hat, or hearing protection used for  
appropriate conditions will reduce personal injuries.  
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.  
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.  
Keep children and bystanders away while operating a  
power tool. Distractions can cause you to lose control.  
Remove any adjusting key or wrench before turning  
the tool on. A wrench or a key that is left attached to a  
rotating part of the power tool may result in personal injury.  
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.  
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.  
Avoid body contact with earthed or grounded  
surfaces such as pipes, radiators, ranges and refrig-  
erators. There is an increased risk of electric shock if  
your body is earthed or grounded.  
If devices are provided for the connection of dust  
extraction and collection facilities ensure that these  
are connected and properly used. Use of these  
devices can reduce dust-related hazards.  
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.  
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.  
When operating a power tool outdoors, use an  
outdoor extension cord suitable for outdoor use.  
Use of a cord suitable for outdoor use reduces the risk  
of electric shock.

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.  
Additional safety rules for angle grinders  
Fully unwind cable drum extensions to avoid potential  
overheating.  
Disconnect the plug from the power source before  
making any adjustments, changing accessories, or  
storing power tools. Such preventive safety measures  
reduce the risk of starting the power tool accidentally.  
When an extension cable is required, you must ensure  
that it has the right ampere rating for your power tool and  
is in safe electrical condition.  
Always switch off before you put the angle grinder down.  
Do not let anyone under 18 years operate this tool.  
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.  
Rags, cloths, cord, string and the like should never be  
left around the work area.  
If you are interrupted when operating the tool, complete  
the process and switch off before looking up.  
Maintain power tools. 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.  
Periodically check that all nuts, bolts and other fixings  
are properly tightened.  
Check the disc before mounting it into the angle  
grinder. Check by striking it with a wooden handle whilst  
balancing the disc on your finger. Listen for the ring and  
do not use if dull, as the disc may be cracked.  
Keep cutting tools sharp and clean. Properly  
maintained cutting tools with sharp cutting edges are  
less likely to bind and are easier to control.  
When the disc is installed, run it for at least one minute  
to ensure that it does not have a fault. It is always  
advisable to stay out of the line of the disc when testing  
or when using the tool.  
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 intended could result in a  
hazardous situation.  
Do not use a disc marked with a lower RPM than that of  
the no load speed shown on the rating plate.  
Use discs only of the prescribed diameter.  
Do not use the angle grinder for buffing or polishing  
under any circumstances.  
Service  
Have your power tool serviced by a qualified repair  
personnel using only identical replacement parts.  
This will ensure that the safety of the power tool is  
maintained.  
Never try to operate the angle grinder without the guard  
in place.  
Do not secure the angle grinder in a vice or work bench  
and use it as a static grinder. It can lead to serious injury.  
Never apply excessive pressure to the disc. It might  
shatter causing personal injury.  
Ensure the work piece to be ground or cut, is held tight  
in the vice or other clamping system.

Always use the side handle and ensure a good grip on  
the grinder housing with one hand and the handle with  
the other hand before proceeding with any work.  
Contents of carton  
The GMC MX100MAG Angle Grinder is supplied with the  
following accessories as standard:  
Make sure that the disc is not in contact with the work  
when you start the grinder.  
Pin wrench  
Side handle  
Be careful not to damage the spindle or either of the disc  
flanges. Damage to these parts could result in disc breakage.  
100mm metal cutting disc  
Instruction manual  
Do not press the spindle lock button whilst the spindle is  
turning.  
Unpacking  
Only use good quality grinding and cut off discs. Cheap  
poor quality discs tend to glaze up which loads the  
motor and can damage it. Use discs for their designated  
purpose only. For instance, do not use cutting discs for  
grinding or metal wheels on masonry.  
Due to modern mass production techniques, it is unlikely  
that your GMC Power Tool is faulty or that a part is missing.  
If you find anything wrong, do not operate the tool until  
the parts have been replaced or the fault has been rectified.  
Failure to do so could result in serious personal injury.  
Watch out for flying sparks. Hold the tool at an angle of  
approximately 15º to 30º to the work piece surface.  
Let the disc do the grinding or cutting at a reasonable  
feed, as overloading will occur if too much pressure is  
applied and the disc slows resulting in inefficient cutting  
and possible damage to the motor.  
When using the grinder, use safety equipment including  
safety goggles or shield, ear protection, dust mask and  
protective clothing including safety gloves.  
ALWAYS WEAR EYE PROTECTION  
Wear goggles  
Wear hearing protection  
Wear a breathing mask

Setting up  
Operation  
Multi-position side handle  
This angle grinder can be used for grinding and cutting  
steel, stone or ceramic workpieces such as pipe, box  
section, rectangular, angle iron  
steel bar, house bricks and tiles.  
Do not attempt to grind wood or  
a soft metal such as lead. The  
material will quickly “fill” the disc  
and render it useless.  
Screw the side handle (6) into the  
most suitable mounting port (4)  
(left side or right side) to suit the  
application. Ensure that the handle  
is fully screwed in place and firm.  
Disc guard  
WARNING. Switch off the grinder and disconnect it from  
the power point.  
Before starting the grinder first  
ensure that the disc, disc guard  
and tool are in good condition.  
NOTE. Grinding operations normally require the angle  
grinder to be held with the grinding disc parallel to the  
plane of the workpiece whilst cutting operations normally  
require the angle grinder to be held with the cutting  
disc at right angles to the workpiece. Take the time  
to find the best combination of front handle and main  
handle positions to suit the task on hand. It can make a  
considerable difference to the levels of convenience and  
safety of operation.  
Position the guard (3) as described in the disc guard section  
so that it will deflect hot sparks away from the operator.  
Switching on and off  
1. Plug the power cord into the power point.

minute to ensure the new  
disc is in good condition.  
Make sure you are wearing  
all the safety gear and that  
you face the grinder away from you.  
3. Clean the flanges and check the new disc.  
4. Holding the angle grinder with the spindle facing  
upwards, check that the inner flange is on the spindle  
and correctly located. The two machined flat sections  
must face the angle grinder and locate in the appropriate  
position on the spindle.  
CAUTION. Do not use excessive force to clamp the disc.  
It could crack it and cause failure during use.  
WARNING. Do not immerse the disc into any type of  
lubricant including water. This angle grinder is designed as  
a dry grinder/cutter. Failure to observe this warning could  
result in a fatal shock.  
5. Place the disc onto the spindle  
with the label facing the angle  
grinder. The hole in the disc  
should locate onto the spindle
