WARNING
When using electric power tools, basic safety precautions including the following, should always be followed to
reduce the risk of fire electric shock and personal injury. Also please read and heed the advice given in the
additional important safety instructions.
READ ALL THESE INSTRUCTIONS BEFORE OPERATING THIS PRODUCT AND SAVE THESE
INSTRUCTIONS.
1. Keep the work area clean and tidy. Cluttered work areas and benches invite accidents and invite injury.
2. Consider work area environment. Do not expose power tools to rain. Do not use power tools in damp
or wet locations. Keep the work area well lit. Do not use power tools where there is risk to cause fire or
explosion. Do not use power tools in the presence of flammable liquids or gases.
3. Guard against electric shock. Avoid body contact with earthed or grounded surfaces (e.g. pipes,
radiators, ranges, refrigerators).
4. Keep children and visitors away from the work area. All visitors and onlookers, especially children
and infirm persons should be kept well away from where you are working. Do not let others in the
vicinity make contact with the tool or extension cord.
5. Store idle tools. When not in use, tools should be stored in a dry, high or locked up place out of reach of
children.
6. Do not force the tool. The tool will do the job better and safer at the rate for which it was designed.
7. Use the right tool. Do not force small tools or attachments to do the job best handled by a heavier duty
tool. Do not use tools for purposes not intended; do not use circular saws to cut tree limbs or logs.
8. Dress correctly. Do not wear loose clothing or jewellery; they can be caught in moving parts. Rubber
gloves and non-slip footwear are recommended when working outdoors. Wear a protective hair covering
to contain long hair.
9. Use safety accessories. Safety glasses and ear defenders should always be worn. A face or dust mask is
also required.
10. Connect dust extraction equipment. If devices are provided for the connection of dust extraction and
collection facilities, ensure that these are connected and properly used.
11. Do not abuse the power cord. Never carry the tool by the cord or yank it to disconnect it from the
socket. Keep the cord away from heat, oil and sharp edges.
12. Secure the work piece. Use clamps or a vice to hold the work piece. It is safer than using your hand and
it frees both hands to operate the tool.
13. Do not overreach. Keep proper footing and balance at all times.
14. Maintain and Look after your tools with care. Keep cutting tools clean and sharp for better and safer
performance. Follow the instructions for lubrication and accessory changes. Inspect tool cords
periodically and if damaged have it repaired by an authorized service facility. Inspect extension cords
periodically and replace, if damaged. Keep tool handles dry, clean and free from oil and grease.
15. Disconnect tools. Switch off the power. Disconnect the plug from the power point before servicing and
when changing accessories such as blades, bits and cutters, and when the tool is not in use.
16. Remove adjusting keys and wrenches. Form the habit of checking to see that the keys and adjusting
wrenches are removed from the tool before switching the tool on.
17. Avoid unintentional starting. Ensure that the switch is in the OFF position before plugging the tool to
the power supply. Do not carry a plugged in tool with your finger on the switch.

18. Use outdoor rated extension cords. When a tool is used outdoors, use only extension cords that are
intended for outdoor use and are so marked.

19. Stay alert. Watch what you are doing. Use common sense. Do not operate a power tool when you are
tired.
20. Check for damaged parts. Before using a tool, check that there are no damaged parts, if a part is
slightly damaged carefully determine if it will operate properly and perform its intended function other
wise replace. Check for alignment of moving parts binding of moving parts, breakage of parts, free
running of moving parts, proper mounting and any other conditions that may affect the operation of the
tool. A guard or other parts that are damaged should be properly repaired or replaced by an authorised
service centre, unless otherwise indicated in this instruction manual. Defective switches must be replaced
by authorised service facility. Do not use the tool if the switch does not turn the tool on and off correctly.

ADDITION SAFETY RULES FOR ANGLE GRINDER
•Fully unwind cable drum extensions to avoid potential overheating.
•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.
•Ensure your mains supply voltage is the same as your tool rating plate voltage.
•Always switch off before you put the angle grinder down.
•Keep the area free of tripping hazards.
•Do not let anyone under the age of 18 years operate this tool.
•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.
•Periodically check that all the nuts, bolts and other fixings are properly tightened.
•Abrasive wheels shall be stored and handled with care in accordance with manufactures instructions.
•Do not store materials or equipment above a machine in such a way that they could fall into it.
•Do not use discs having a maximum permissible speed below the tool rated marked RPM.
•Inspect the grinding wheel before use, do not use chipped, cracked or otherwise defective products. 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 to the sound it makes if it rings it is ok if it sounds dull it may be cracked and needs
to be replaced.
•Ensure that mounted wheels and points are fitted in accordance with the manufacturers instructions.
•When the disc is installed, run it for at least a 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 in general use.
•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.
•Never try to operate the angle grinder without the guard in place .
•Do not use separate reducing bushings or adaptors to adapt large hole abrasive wheels.
•For tools intended to be fitted with threaded hole wheel, ensure that the thread in the wheel is long enough to
accept the spindle length.
•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 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 non metallic objects) and avoid
damaging internal parts.
•If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly
qualified person in order to avoid hazard.

•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 both hands and ensure a good handgrip on the grinder before proceeding with any work
•Make sure that the disc is not in contact with the work surface when you start the grinder.
•Be careful not to damage the spindle or either of the disc flanges. Damage to these parts could result in disc
damage or breakage.
•Only use good quality grinding and cutting discs. Cheap or 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 for masonry.
•Watch out for flying sparks. Hold the tool at an angle of approximately 15°to 30°to the work piece surface.
when using discs.
•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, and safety shoes.
